Customer Reviews

Customer Review: “First off, this thing is massive. So if you are considering using this in your build, make sure that you have room to clear your GPU and such. That being said, I used this for a new build for my son and it is working perfectly. I love that it’s not loaded down with RGB and only has the LCD display to give CPU frequency, load %, power draw, and temperature. It is designed to fit the 5mm offset on an AM5 to align with the hotspot area. Installation was simple and over the past few days, my son has been putting his new build through the paces with lots of FPS gaming and he says that he’s never heard the fans on the cooler ramp up for more that a few seconds and the temps have never gotten over 50 degrees Celsius. Highly recommend.”

Customer Review: “Fantastic cooler, quite but can ramp up in noise if the CPU usage increases rapidly but once at high usage quiet downs again. Loving the functionality of the fan slider so it doesn’t interfere with the RAM slots. Will advise due to the size depending on where you PCIE slot is for you GPU and its size, the cooler may end up touching it resulting in you having to carefully adjust your GPU”

Customer Reviews

Customer Review: “My liquid cooling kit for my ibuypower machine failed and machine keep shutting down after 60s. after monitoring the temperature i found the cpu temperature spike to beyond 90 and shut it down. Quickly look online for a replacement and found this thermalright assessin x120 for a good price. I have the SUS TUF X470-PLUS GAMING board. Removal of the water cooling kit was a bit harder but installing the thermalright assassin as easy and the machine was maintaing between 40 to 60 celcius without the fan noise is pretty low so it serve it job. has been on the setup for a few months and so far no issues yet.”

Customer Review: “Mister Twiggly is an ardent gamer, and his home-built gaming rig, while ancient, is capable. However, the stock cooler was getting a little noisy at times, so it was time for a replacement. Enter the Thermalright Assassin X120 Refined SE.Installation was fairly straightforward, though he had to pull out the motherboard to attach the backplate. From then on it was plain sailing.Testing showed that the CPU temperature is 10-15°C cooler at rest and 20-25°C cooler under load than the stock cooler, which he is holding in his right paw. Moreover, fan noise is barely noticeable – hardly surprising, since the fan is huge and runs far more slowly than its predecessor to cool that monster heatsink. This is music to Mister Twiggly’s fluffy but sensitive ears.A very good solution at a modest price.Mister Twiggly says “Hurrah for Thermalright!”, and gives this product his highest recommendation.”

Customer Review: “Great cooling temperature with overclock cpu ! Gets the job done”

Customer Review: “I grabbed this cooler for a new build I’ve been working on, as I’m familiar with Jonsbo’s chassis offerings and have also tried one of their coolers previously, with great success.The cooler arrived in a smallish box packed with parts used to support various socket types, as one would expect. The instructions are clear and easy to understand, describing all the details one requires to complete the assembly. It also contains a tube of thermal compound for the CPU to heatsink thermal transfer.Assembly was as easy as I’m accustomed to from building many coolers over the years. However, it’s not tough, so if this is your first, you’ll be fine. Just take your time. In my case, this went on a socket 1200 board, and the fit was perfect.In use, the fan speed remained low and quiet even under load, as the heatsink is very efficient with the six thermal pipes. At 270 degrees of thermal dispersion, most users will be just fine and experience smooth, quiet cooling.installed and with the RGB LEDs enabled, it’s a great-looking cooler and shows off the unique style that Jonsbo is bringing to the PC building arena. Even better, Jonsbo is showing off its ability to offer great performance and good looks at a reasonable price.I’ll continue to check out Jobnbo parts as I’m impressed with the few that I have already tried.”

Customer Reviews

Customer Review: “My Dell Studio XPS 9100 desktop’s cooler was not keeping my CPU cool – due to the well-known plastic tabs breaking on the cooler – keeping the cooler from making solid contact with the CPU. I tried to order a replacement from Dell for a perfect-working computer…but Dell no longer sells a cooler for that model. Planned obsolescence, I presume even though my XPS runs perfect in all other regards.So i checked a few aftermarket coolers that some said “might work” and after viewing some YT videos, this Noctua U9S cooler seemed to be my best option. Before, my core temps were almost “off-the-charts” reaching 90-100 Celsius regularly with very little load. After (easily) installing this cooler, my minimum core temps went from 50c to under 25c in all six cores. My maximum core temperatures decreased from over 95c in all six cores to about 55c. And the fan that comes with the cooler is much quieter than the OEM fan provided by Dell. All the positive reviews I’ve read about Noctua, turned out to be 100% true.To make this work, Noctua had to send me a modification kit for my Intel 1366 motherboard. I just had to provide proof of purchase of the U9S and my dell 1366 socket. Once I did that, Noctua customer support mailed me the kit I needed. Just great customer support. And my computer is now running cool and calm. Should help me get another year, or two, out of Michael Dell’s computer.****UPDATE – I bought this Noctua CPU Cooler Feb. 2022. March 2024 it is still working like new. My CPU never runs hot and the fan is extremely quiet. One of the best Amazon purchases I’ve made in the last 15 years. Good company to work with, too.”

Customer Review: “I was recommended this cooling system for my 13th gen i7 because it was overheating real bad i was not sure about a air cooled when people tell you that the only way to go is liquid cooled but i do have to give it to this cooler i play lots of games and my temps used to go up to almost 100c and now under load the max i see is around 50c to 70c max and its super nice when gaming. I have had my system for a couple of years now and it works great for the price point and compatible with most fans. It fits in the case and super quiet. The build quality is nice and should stand the test of time. All round great solution when on a budget.”

A few highlight points:With 6 heat-pipes and a dual-tower heatsink, this cooler handles high thermal loads surprisingly well for the price.It supports both Intel (LGA 115x/1200/1700) and AMD (AM4/AM5) sockets out of the box — easy to integrate into different systems.It is impressively quiet. According to the official spec the noise level tops out at ~25.6 dBA, which means minimal fan noise in daily use.The ARGB lighting is a nice bonus for anyone who cares about aesthetics, and it does not seem to compromise performance.My experience in use:Installation was straightforward (with the back-plate and mounting brackets included). After setup I noticed lower idle and load temperatures vs the stock cooler, and the system remained quiet even under sustained load. It also had good clearance around my RAM slots and GPU (always good to check fit in your case). In terms of value vs performance, this cooler really stands out.Minor note:You’ll want to check your case’s CPU cooler clearance, the heatsink is ~155mm tall.Also, if you’re doing extreme overclocking or very high-end CPUs at 300 W+ loads, this may not quite match the very top-tier 280/360mm liquid-coolers, but for most builds it gives excellent bang for the buck.Bottom line:If you’re looking for a high-performance air cooler that doesn’t break the bank, the Peerless Assassin 120 SE ARGB is hard to beat. Highly recommended.”

Customer Review: “Installed this cooler in my PC, and it’s honestly one of the best air coolers I’ve used. Temps dropped significantly compared to my old one, and it’s super quiet even under load. Installation was straightforward, and the ARGB lighting looks clean inside the case. Build quality feels premium, and the fans are smooth and silent. For its price, it’s an amazing value for keeping your CPU cool. It works perfectly as it is compatible with my R9 5900 XT. It has lasted around 2 years since I bought it and looks nice!”

Customer Review: “So my use case for this is in a mATX home server with an 8th gen i7-8700k, 32GB of RAM, NVIDIA Quadro P1000 GPU and approx 100TB of storage. The case is a Fractal Meshify 2 Nano. I have 3x 3.5″ drives internally, as well as 2x 2TB M.2 SSDs (Windows 11 Pro on one, and mirror backup of the OS on the other). This server is primarily used for data backups, Plex Media Server and also does a lot of the grunt work for encoding blu-rays to MKV files via Handbrake. The CPU barely ever needs to work hard, and my existing cooler was a well trusted and heavily used 10 year old Coolermaster Hyper 212 cooler. It’s an exceptional air cooler. However, as you can see in the original installation the flaw in the plan. It blows warm CPU heat onto one of the 24TB Seagate Drives. I actually had to RMA the previous drive in that location, likely due to heat. Despite the cool temps inside the case, the blowing of warm air directly onto it probably did it no favours.Enter, a replacement AIO! There is no longer warm air onto the drive at all. I have the radiator front mounted, and venting out of the front panel. This is opposite to how most of my builds are since I typically pull air in from the front and out via the rear. Well, this different layout makes sense in this configuration. I will be adding a 120mm intake fan in what little free space is above the CPU.Installation was stupidly easy. I just picked the Intel parts, (Yes, it doesn’t say on the listing but it WILL fit a LGA 1151) and then mounted the back plate. I then had to shuffle the top mounted HDD back an inch or two, and finagle the front radiator into place without the fans (micro ATX case, so tight space). Once I had it set just right, I pre-wired the fans and routed their cables and then secured them to the radiator. I reattached the vent panel on the bottom of this particular case for maximum airflow efficiency. Once I connected the 4 pin fan header and 4 pin water pump header, I installed the pump/block itself. I was pleasantly surprised to find that the fan headers are actually still accessible after mounting the pump. These were completely blocked off by the old air cooler.I fired it up, ran some bench testing to verify it was working – as well as see what noise level was like. It’s actually pleasantly quiet! Some pumps have a whine, but this one does not. I have used a Corsair Capellix H150i in my gaming build for several years so this is my only AIO to compare with – I have so far been impressed. Just 15c after a reboot from doing stress tests, temps barely kicked up to 19-21c during testing. This is a big improvement over the air cooler. At this price point, you cannot go wrong. Great price, great fit, great compatability. I am happy.”

Customer Review: “It looks beautiful and minimalistic. The aio not only feels premium but also gets the job done by keeping my cpu temps cool i get temps between 45° C – 50°C idle with the highest of 68°C during gaming on a Ryzen 7800x3d in an Asus A32 case. It comes with two high quality fans that are silent even during gaming times. I’ve used it on mATX and an ATX cases in which installation was simple.”

9. Noctua NH-L9x65 chromax.Black Low-Profile CPU Cooler

Noctua NH-L9x65 chromax.Black Premium Low-Profile CPU Cooler (65mm) fo

The NH-L9x65 chromax.Black is the premium, all-black version of Noctua’s famous low-profile cooler. At just 65mm tall, it’s designed for the most space-constrained builds, like ultra-compact Mini-ITX or HTPC cases. It uses a highly efficient 95x95mm heatsink and the renowned NF-A9x14 PWM fan to deliver cooling performance that defies its size. The all-black finish integrates perfectly with modern builds, and it maintains Noctua’s legendary quiet operation and build quality.

Key Features That Stand Out

  • Ultra-Low 65mm Profile: One of the shortest high-performance coolers available, fits in almost any case.
  • 95x95mm Low-Profile Heatsink: Provides a large surface area in a compact footprint, excellent for heat dissipation.
  • NF-A9x14 PWM Fan: A slim, high-quality 92mm fan with excellent static pressure and near-silent operation.
  • All-Black chromax Finish: Sleek, modern look that matches any build theme without the traditional Noctua beige.
  • Great RAM/PCIe Clearance: The small baseplate and fan ensure no interference with motherboard components.

Why We Recommend It

When you have absolutely no vertical space, this is the cooler you choose. Noctua took their award-winning low-profile design and gave it a sleek black makeover. It’s the only cooler we’d trust to keep a high-end CPU like a Ryzen 7 7700X or Core i7 cool in a tiny case. The performance is astonishing for its height, and the noise levels are impressively low. If you’re building a small form factor masterpiece and need a cooler that won’t limit your component choices, this is it.

Best For

Constructors of ultra-compact Mini-ITX PCs, Home Theater PCs (HTPCs), and small form factor (SFF) builds where CPU cooler height is severely restricted (under 70mm). Ideal for CPUs up to ~105W TDP that need reliable, quiet cooling in a tiny package.

Pros and Cons

Pros:
  • Unbeatable combination of low height and high cooling performance.
  • Extremely quiet operation, a hallmark of Noctua’s fan engineering.
  • Beautiful all-black aesthetic that fits modern builds perfectly.
  • Excellent compatibility; never blocks RAM or PCIe slots due to its tiny footprint.
  • Includes Low-Noise Adaptor and all necessary mounting hardware.
Cons:
  • Premium price for a low-profile cooler.
  • Not suitable for the highest TDP CPUs or heavy overclocking (it’s physically limited by size).
  • The 92mm fan, while excellent, will get louder under heavy load than a larger, slower-spinning fan.
  • May require careful case airflow planning to ensure hot exhaust doesn’t recirculate.

Customer Reviews

Customer Review: “I’m running this on my Ryzen 7 7700X and honestly, it handles it way better than I expected. Even when I’m pushing it hard with heavy workloads or gaming, it peaks at around 75°C (167°F), which is pretty wild for a low-profile cooler.​The all-black look is super clean and the build quality feels premium. If you need to save space but don’t want your CPU cooking, this is definitely the move.”

Customer Review: “This is noctua…the best brand for cooling period. Extremely easy to install and very quite. The black matches my build and the price to performance including noise can not be beat.”

Customer Reviews

Customer Review: “After years with the G1, the upgrade to the G2 has been incredible. The revised design solves the clearance issues that previously forced me to run only a single fan due to motherboard and RAM interference.The Thermal DifferenceThe “heat soak” I experienced with the G1 is gone. Using FanControl to sync with my exhaust, the “wicking” is night and day:Arc Raiders (High/Epic Settings): Dropped from 80°C–85°C (G1) down to 58°C–65°C (G2).Idle/Lobby: Dropped from 45°C–60°C down to 35°C–48°C.Build Quality & InstallationThe G2 feels much denser; the fins are sturdy and don’t “ping” or flex during installation like the G1. The shift in the bracketry—moving the stack about 1/8″ inward and 1/2″ toward the bottom—drastically improved clearance, finally allowing a dual-fan setup.A few standout details:They included a custom Wera Torx driver. If you know tools, you know that’s a premium touch they didn’t even have to include.Aesthetics: The all-black finish perfectly matches my color-coordinated build and will for others.Quiet Efficiency: Paired with “be quiet!” Pure Wings-3 140mm fans at 60–80% duty cycle (1000–1200 RPM), the rig is whisper-quiet.I’ve stuck with air cooling over AIOs for the reliability and ease of installation. In a climate-controlled room with positive airflow, this unit is a beast. If you’re debating the upgrade for the clearance improvements alone, it’s worth every penny.”

Customer Review: “Noctua has always been reliable (at least for me) and this huge cpu cooler (using it on a 9950x3d) is a decent alternative from liquid cooling. 8 heat pipres and robust noctua quality fans keep my ryzen 9 from throttling (stressed using aida64 and cinebench). Idle temps (ambient room temps in humid/tropical Fiji right now get up to 30degCelcius) so 50degCel is fine at idle (no I don’t use aircon, we are fan people and am not rich enough to comfortably/consistently afford AC cooling). Under stress temps shoot up to 84 and sometimes has spiked to 88degC but still manageable and actually really cool (no pun) vis-a-vis ambient tropic humid temps. I have tried testing in AC controlled environment at my friends house (low as 18degC) and obviously the cooler performs way better with idling the 9950x3d at 40degC (under volted only with negative curves at 31/25 per ccd, i don’t OC) and load temps never exceeding 78degC. Please don’t take this the wrong way, this cooler is just as decent as an overpriced AIO or a reasonably priced AIO and lesser failure points. This is my backup if my current 420aio (no need to name names) ever craps out. Noctua gives me peace of mind and this cooler is a piece of cake to setup and use. Noise is negligible for me (using a havn hs 420 non vgpu; maxed 140 fans as recommended). I don’t have any form of anechoic chambers (thanks Steve) to test for noise but to my naked ears, a noticeable “whoooom” sound (somewhat subdued) under load is fine while normal use noise is non-existent (subjective since I boldly assume my hearing is average/normal). I would buy again but given the quality, there will be no need (unless I can ever afford to build another PC). Overall, vinaka (thanks) Noctua and Amazon. Vinaka vakalevu from hot hot hot Fiji.”

Complete Buying Guide for What Is The Best Cpu Cooler

Essential Factors We Consider

Choosing the right CPU cooler hinges on a few key factors. First, CPU Thermal Design Power (TDP) is your baseline. A cooler rated for 150W will struggle with a 250W CPU under load. Second, case compatibility is crucial—measure your case’s maximum CPU cooler height (for air) or radiator support (for AIO). Third, consider RAM clearance; some large air coolers overhang DIMM slots, blocking tall RAM modules. Fourth, think about noise tolerance—larger fans spin slower for the same airflow, often making dual-tower air coolers quieter than single-tower or AIO pumps under load. Finally, socket compatibility must match your motherboard (AM5, AM4, LGA1700, etc.).

Budget Planning

Your budget directly dictates your options. Under $40, you get solid single-tower air coolers that handle mid-range CPUs. The $50-$100 range is where the best value lives—high-performance dual-tower air coolers like the Peerless Assassin or capable 240mm AIOs. Over $100, you’re paying for flagship air coolers (Noctua NH-D15) or premium 280/360mm AIOs with advanced features. Remember, the best CPU cooler is the one that meets your cooling needs without overspending. A $30 Thermalright can often outperform a $120 older AIO.

Final Thoughts

For most users, a high-quality dual-tower air cooler offers the best blend of performance, quietness, and reliability. AIOs make sense for cramped cases where a large air cooler won’t fit, or for those who prefer the aesthetic. Low-profile coolers are non-negotiable for SFF builds. Don’t over-spec—a Ryzen 5 doesn’t need a Noctua NH-D15. Match the cooler to your CPU’s heat output, your case’s limits, and your personal noise preferences. The SK620V leads for high-end AM5 air cooling, the Assassin X120 is the unbeatable budget king, and the NH-D15 G2 is the air-cooling apex predator.

Frequently Asked Questions

Q: Is a liquid cooler (AIO) better than an air cooler?

A: Not inherently. High-end dual-tower air coolers now match or exceed 240mm AIO performance in many tests, with zero risk of pump failure or leaks. AIOs excel in cases with poor airflow or where a large air cooler won’t fit. For most builds, a top-tier air cooler is simpler, more reliable, and quieter. AIOs are chosen for specific aesthetics or extreme heat dissipation in very small cases.

Q: How do I know if my CPU cooler is compatible with my motherboard?

Q: What’s the difference between a single-tower and dual-tower CPU cooler?

A: A single-tower has one heatsink fin stack and usually one fan. A dual-tower has two separate fin stacks, typically with a fan on each side (push-pull). Dual-towers have vastly more surface area for heat dissipation, allowing them to handle higher TDPs and often run fans at lower, quieter speeds. They are also much taller and wider, requiring more case space.

Q: Do I need to replace the thermal paste on my CPU cooler?

A: The paste that comes pre-applied or in the box is perfectly adequate for most users. High-end thermal paste can offer a few degree improvement, but it’s marginal. You should replace the paste if you remove the cooler for any reason, as the bond is broken. Always clean off old paste thoroughly with isopropyl alcohol before reapplying new paste.

Q: My CPU temperatures are high even with a good cooler. Why?

A: Check your case airflow first. A great cooler needs cool air to work. Ensure you have a balanced intake/exhaust fan setup and that the cooler’s fans are not fighting against negative air pressure. Also, verify the cooler is mounted correctly with even pressure and the right amount of thermal paste (a pea-sized dot or a thin line, depending on the cooler). Lastly, ensure your CPU’s voltage settings aren’t excessively high from an auto-overclock or BIOS setting.

Finding the best CPU cooler doesn’t have to be overwhelming. By focusing on your specific CPU’s needs, your case’s constraints, and your budget, you can narrow it down quickly. The SK620V stands as our top overall pick for its innovative features and raw power, while the Thermalright Assassin X120 remains the unbeatable value champion. For those with space constraints, the Noctua NH-U9S and NH-L9x65 are simply the best in class. Remember, a good cooler is an investment in your processor’s lifespan and your system’s quiet operation. Take a look at the options above, check the prices, and you’ll find the perfect match for your next build.
