Customer Reviews
Customer Review: I was seriously starting to regret my entire build. I have an i9-12900KS and couldn’t even get into the BIOS — just black screens and endless frustration. Eventually realized the issue might be thermal-related, so I picked up the Hyper 212 Black after seeing solid reviews. Installation was smooth, especially for an air cooler this size. The mounting brackets for LGA 1700 worked without any fuss. Once it was on, temps dropped dramatically — like, instantly noticeable. And best of all? My system booted right up. BIOS, Windows, everything. The SickleFlow fan is surprisingly quiet, and the all-black design with the aluminum top gives it a premium look… Honestly can’t believe this solved the issue, but I’m glad it did.
Customer Review: I like this product. Here’s my day 1 experience…First you need to be ok with potentially removing the mother board, clearing thermal paste and reapplying thermal paste. If that is too much for you then find another solution! My stock AMD fan was driving me CRAZY! It was so loud… At that point I looked for a solution and here’s my experience: Good: + Price to me was fair and Amazon arrived the same day! + Very Quiet (compared to my stock fan) + Keeping my cpu between 38 – 60C + Comes with thermal paste! + fits Intel/AMD (mine is AMD) + able to add a second fan but not included… All in all, I like this solution. It’s very quiet, inexpensive and working nicely. Happy Computing!

Customer Reviews
Customer Review: I recently upgraded my system’s cooling with the Thermalright PS120SE ARGB, moving from a single-fan Cooler Master air cooler hyper 212 RGB, and the difference is night and day. This dual-tower, dual-fan behemoth has completely transformed my PC’s performance and acoustics. Previously, with my single-fan Cooler Master cooler Hyper 212 RGB, I was constantly battling high temperatures… The jump to a dual-tower design with two 120mm fans immediately paid off. My temperatures have dropped dramatically across the board. But what truly surprised me was the NOISE LEVEL. The Thermalright PS120SE is whisper-quiet, even when the fans ramp up. The ARGB lighting is a nice bonus… It’s the raw cooling power and near-silent operation that make this cooler a truly worthwhile investment.
Customer Review: Note that the cooler’s size means one fan will likely interfere with non low profile RAM (Vengeance LPX). The fan that interferes (if it does) can be moved slightly upwards, which will not harm performance in any meaningful way but will look a bit worse. Reasonably quick to assemble… Comes with thermal paste, keep in mind the paste is very thick… Keeps even the Ryzen 9 9950x3d at good temps up to a 78 celcius max after sustained workloads, with minimal thermal throttling. The cooler is overall quiet (no AIO pump whir helps), well built.
7. Noctua NH-U9S Premium CPU Cooler
The Noctua NH-U9S is a compact, single-tower air cooler that shares Noctua’s famous build quality and quiet operation in a slightly larger (125mm) form factor than the L9x65.

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… 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… 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… All the positive reviews I’ve read about Noctua, turned out to be 100% true. UPDATE – I bought this Noctua CPU Cooler Feb. 2022. March 2024 it is still working like new.
Customer Review: I was recommended this cooling system for my 13th gen i7 because it was overheating real bad… 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.

Customer Reviews
Customer Review: This is a review of the Thermalright Phantom Spirit 120SE. I read many performance reviews online before purchasing this. According to those reviewers, this offers top-tier cooling vs noise at a fraction of the price. It even competes with some AIOs. I recently replaced an AIO with this, the first air cooler I’ve used in a while. I did it because this computer is getting long in the tooth, and I’m more concerned about long-term reliability than a couple of degrees Celsius. Compared to my old NZXT Kraken X63, this gets very similar cooling performance. The temperatures fluctuate more than they did with the AIO, but the minimum idle temperature is now slightly lower than it was with the AIO, and the max temps are only a couple of degrees hotter than they were with the 280mm AIO. This is all despite the fact that I used about half of the normal amount of thermal paste due to a screwup on my part. As long as you’re not using a processor with a very high TDP, this is the ideal cooler.
Customer Review: I’ve been using the Thermalright Phantom Spirit 120SE with my AMD Ryzen 7800X3D, and I couldn’t be more satisfied with its performance. This cooler has exceeded my expectations in every way. Performance: The Thermalright Phantom Spirit 120SE keeps my 7800X3D at idle temperatures in the 40s, and during gaming sessions, it stays impressively cool between 50s and 60s. Price/Performance Ratio: Considering its price, the performance of this cooler is outstanding. It’s hard to find another cooler that offers such a great balance of cost and cooling capability. Installation: The installation process was straightforward, and the included instructions were clear. The cooler fits perfectly in my mid-tower case without any clearance issues. Build Quality: The build quality of the Phantom Spirit 120SE is solid. The fins and heat pipes are well-constructed, and the overall design is sleek and functional. Noise Levels: One of the pleasant surprises was how quiet this cooler is. Even under load, the noise levels are minimal, making for a much more enjoyable gaming experience. Conclusion: If you’re looking for a high-performance cooler for your 7800X3D that won’t break the bank, the Thermalright Phantom Spirit 120SE is an excellent choice. It delivers exceptional cooling, is easy to install, and offers fantastic value for money. Highly recommended!

The RS120 ARGB fans look great and provide smooth, vibrant lighting that syncs perfectly with other components. Build quality is exactly what you’d expect from Corsair: solid, reliable, and premium. If you’re looking for a powerful, low-noise 360mm AIO with clean RGB and easy installation, this cooler is a fantastic choice.
Customer Review: Works and performs great!! with some of the higher demanding CPU games like Starship Troopers Extermination, and POE2 which run my ryzen 5 5600 at about 70-90% my CPU temp never got over 62C !!! i have the current fan config set to AIO cooler set to intake, drawing in fresh air to the CPU first, then the case, then i have one fan below the GPU also intake heavy gaming GPU never reached more than 72C!! with two exhaust fans on rear and top as well. this fan config seems to work really well for cooling! recommend full corsair case, AIO cooler is quiet and easy to install. all hardware included. U CAN control all fan RGBlights at the same time using corsair Commander duo. YOU DO NOT NEED ICUE LINK FANS OR ICUE HUB FOR RGB. just duo and corsair app.
10. CORSAIR Nautilus 360 RS Liquid CPU Cooler
This is the non-ARGB version of the Nautilus 360 RS. It’s functionally identical in terms of cooling performance, pump, radiator, and mounting hardware. The key difference is the fans: this model uses standard, non-RGB RS120 fans. For users who don’t care about RGB lighting and want to save a few dollars, or who plan to install their own set of fans for a custom look or specific performance profile, this is the smarter buy. You get the same excellent 360mm AIO cooling performance from Corsair without the added cost of addressable lighting.
Key Features That Stand Out
- ✓ Same 360mm AIO Performance: Identical radiator, pump, and cold plate as the ARGB model.
- ✓ Standard RS120 Fans: High-performance, low-noise fans without RGB.
- ✓ Cost-Effective: Lower price by omitting RGB hardware.
- ✓ Clean, Minimalist Look: Perfect for builds without RGB or with lighting from other components.
Why We Recommend It
We recommend this specific model for the 9800X3D if you’ve decided on a 360mm AIO for its cooling potential but don’t want or need RGB lighting on the radiator fans. It’s the sensible choice for a performance-focused, clean-looking build. You can always add your own aftermarket fans later if you change your mind, but the included Corsair fans are already very good. It’s about getting the core liquid cooling benefit without paying for a feature you won’t use.

Pros and Cons
Pros:
- Identical high-performance cooling to the more expensive ARGB model.
- Lower cost by skipping RGB features.
- Quiet pump and effective fans.
- Same great Corsair build quality and warranty.
- Simpler for users who don’t use RGB control software.
Cons:
- No RGB lighting on the fans (obviously).
- Still requires a large case with 360mm radiator support.

- Fan cables are not daisy-chained like the ARGB model (may have more cables).
Customer Reviews
Customer Review: The Corsair Nautilus 360 RS delivers excellent cooling performance. It keeps temperatures low even under heavy load and runs quietly. Easy to install and great build quality. Highly recommended!
Customer Review: Had a PC that had been in storage for a long period of time and needed a cooler replaced. This unit basically was plug and play on a PC that was built in 2011. Had zero compatibility issues and PC temps haven’t budged since. With Corsair’s known quality this should last the life of the PC and longer. The efficiency is noticeable and the sound isn’t, it is very quite for an AIO. It is a bit simple by todays standards of RGB and onboard diagnostics. If you need a simple effective upgrade this is it.
Complete Buying Guide for Best Cpu Cooler For Amd Ryzen 7 9800X3D
Essential Factors We Consider
Choosing the right cooler for your 9800X3D isn’t just about picking the biggest number. First, consider your case compatibility. Measure the available CPU cooler clearance (height for air coolers, radiator support for AIOs). The 9800X3D has a 105W TDP, but it can spike higher, so aim for a cooler rated for at least 120-150W for comfortable headroom. Noise levels are crucial—check reviews for dBA ratings or user comments about fan whine. RAM clearance is a big deal for dual-tower air coolers; ensure it fits over your memory modules. Finally, think about aesthetics and RGB. Do you want a clean, functional look, or integrated lighting that syncs with your build?
Budget Planning
You don’t need to spend a fortune for excellent cooling. For the 9800X3D, a budget of $50-$80 gets you a top-tier air cooler like the Thermalright Peerless Assassin or Phantom Spirit, which will handle the CPU with ease. Spending $80-$120 opens up premium air coolers like Noctua’s offerings and high-performance 240mm AIOs. For the ultimate in cooling capacity and a clean look, a 360mm AIO from Corsair or another reputable brand will run $120-$200. Remember, the stock Wraith Prism is “free” but only suitable for basic, well-cooled cases.
Final Thoughts
The AMD Ryzen 7 9800X3D is a fantastic CPU that deserves a cooler that can keep up. The good news is that you have outstanding options at every price point. For most users, a high-end air cooler like the Thermalright Phantom Spirit 120SE or Peerless Assassin 120 SE provides the best blend of performance, silence, reliability, and value. Only step up to a 360mm AIO if you have the case space and specifically want the lowest possible temperatures for extreme overclocking or a pristine aesthetic. Avoid the stock cooler for any sustained heavy workloads.
Frequently Asked Questions
Q: Can I use the stock AMD Wraith Prism cooler with the Ryzen 7 9800X3D?
A: You can, but it’s not recommended for optimal performance. The Wraith Prism is adequate for light gaming and general use in a well-ventilated case. However, during sustained all-core workloads or in a case with poor airflow, the 9800X3D will thermal throttle, losing performance. A dedicated aftermarket cooler is a worthwhile investment to unlock the CPU’s full boost potential.
Q: Is an AIO liquid cooler necessary for the 9800X3D?
A: No, it’s not necessary. Modern high-end air coolers like the Thermalright Phantom Spirit 120SE or Noctua NH-D15 perform on par with, and sometimes even better than, 240mm and 280mm AIOs, with zero risk of leaks. A 360mm AIO offers a slight edge in extreme, sustained loads and provides a different aesthetic, but a top-tier air cooler is more than sufficient for the 9800X3D at stock or with PBO enabled.
Q: What’s the best cooler for a small form factor (SFF) PC with a 9800X3D?
A: The Noctua NH-L9x65 is the undisputed champion for low-profile cooling. At just 65mm tall, it’s designed for the most compact ITX cases and still manages the 9800X3D’s heat impressively. The Noctua NH-U9S (125mm) is another excellent, slightly more powerful option for SFF cases with a bit more vertical clearance.
Q: How do I know if my case can fit a dual-tower air cooler?
A: Check your case’s specifications for “CPU Cooler Clearance.” Dual-tower coolers like the Thermalright models are typically 154-155mm tall. Most mid-tower and full-tower cases support this, but many compact or SFF cases do not. Also, check the width—these coolers are wide and may interfere with tall RAM sticks or the side panel of some cases.
Q: Should I prioritize low noise or maximum cooling performance?
A>For a 9800X3D, you shouldn’t have to choose. Coolers like the Thermalright Phantom Spirit 120SE and Noctua NH-U9S offer near-silent operation at typical fan curves while providing more than enough cooling headroom. The loudest coolers are usually those being pushed to their absolute limit. Choose a cooler with a 10-15W performance buffer over your expected CPU power draw, and you can run it quietly and cool.
Ultimately, pairing your Ryzen 7 9800X3D with the right cooler is one of the most impactful upgrades you can make. It ensures your investment performs at its peak, stays quiet during your gaming sessions, and runs reliably for years to come. Use our guide to find the perfect match for your case, budget, and aesthetic, and enjoy everything this incredible CPU has to offer.
