Customer Reviews
Customer Review: My Ibuypower water cooler failed on my system. (I discovered this is very common).I was debating on either getting a water cooler or going to Air cooling. I checked a lot of videos online and this air cooler kept coming up in the top 5 replacement recommendations over and over again. (search water coolers vs Air coolers)Since I don’t do any overclocking and the fact that they are much more reliable, I bought this unit.It works really great. It cost so much less than a water cooler and (in my opinion) is easier to install that a water cooler unit with hoses and radiator and cpu block.Positives:Very AffordableCools very wellVery well madePackage comes with everything you need. (different cpu socket mounts and thermal paste)Extremely reliable. (no worries about coolant leaks or pump failure or in my case, clogged lines)The fans that come with it seemed pretty quiet. (more than my cheap water cooler fans)Negatives:Can be a little difficult to install. The most difficult part was installing the fans.The instructions could be better. (they’re not horrible). I do recommend watching online videos.Its big, you definitely need to make sure you have enough room in your case.
Customer Review: Works great so far. 10900k at idle was sitting at around 30°c when the ambient temp in the room was 85°f. This does come with its own tube of thermal paste but I had some leftover Thermal Grizzly Kryonaut so I used that instead. Not sure how good or had the Thermalright paste is but its a pretty big tube of it, its enough for 5-6 PCs. Can’t comment on how loud it is, I couldn’t hear it but my room has a lot of background noise. All in all installation was fairly simple (its pretty much like any other after market air cooler) and it did include a 4pin splitter so if you only have one cpu fan header you can still run both fans that come with this cooler. And for the price its a no trainer. This cooler is essentially the modern era version of the Hyper 212 Evo.

Customer Reviews
Customer Review: Good cooler but was delivered broken and had chipped front plate out the box.
Customer Review: I have used a lot of different types of coolers in the past. I’ve also had a lot of different amd cpus in the past throughout my time with building my own gaming computers. In that time, usually the CPUs I would buy would come with a cooler included from AMD which I would try. Most of these on the 2600 or 3600 would really just not handle what they’d need to. I ended up going with something else like a hyper 212 or something.I ended up getting this included with a 5700x a few months back and decided to give it another try because it looked so much beefier than what I’d seen in the past. They have definitely improved these quite a bit. I was pretty impressed with thermals for something like this. I like the RGB of the fan as well and the fact that the fan sits flat for the look of it instead of going side to side like other coolers.For the price of this one, I decided to pick up another for a new build I’m doing. I think it’s a good value for this cooler overall.

Customer Reviews
Customer Review: I haven’t built a decent desktop since 2008. I thought it was about time to build a new one. I went with a Gigabyte Aorus Pro, with this AMD Ryzen 7 9700X. Couldn’t be happier! It over clocks great (5.38GHz on all cores), temps are really good, it’s fast, and I think it is a great balance between price and performance. It has performed very well on all of the benchmarks I have tried. I don’t game and my new graphics card just died, so I’ve been using the onboard graphics. It has been performing quite well for my needs.
Customer Review: Easy to install, fast to load games or web browsers. Didn’t have any compatibility issues. And overall cooling is normal. Would recommend.

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.
9. Thermalright Assassin X120 Refined SE CPU Air Cooler
The Thermalright Assassin X120 Refined SE is a single-tower air cooler that offers excellent performance for its size and price.

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 Reviews
Customer Review: Previously had the cheap ThermalTake cooler, and the difference is about 12C at idle. Even running games like Cyberpunk, and my Ryzen 3600 would get into the 80s. With this one, it peaked at 73C, even when running a stress test.Installation was simple, and much easier than the ThermalTake I had previously. Came with thermal paste applied already, which seems to be doing just fine. RGB works as expected, though the outer ring seems to have an unchangeable rainbow effect. I haven’t looked in to changing that, it doesn’t bother me much. Only thing I have an issue with, this didn’t include the mounting brackets. Would have been nice to have, even if it ended up being a backup.Cooling is much better than I anticipated, particularly while gaming. I don’t do much that requires a heavy CPU load, and while gaming I would see temps in the 80s. Most of my games now run well below that, usually under 60C. This cooler is also much more quiet than the ThermalTake. Can no longer hear a whine as the fan speed picks up.I did pair this with a Lian Li LANCOOL II Mesh case, which is a big factor here. However, with my previous case’s doors open, I still didn’t see idle temps around 38C. Usually in the low 50s.
Customer Review: This cooler runs my 1600AF chip at 25 degrees C at idle. I know, when I was a child in America my teachers taught us the decimal system and promised us that when we were their ages, the US would have standardized the Metric system. Four pin Fan power and then optional connectors 4Pin ARGB or 3 pin to USB header. The 4 FAN is hard wired in and the two ARGB or USB header (9 pin USB 2.0) are optional to provide the illumination and control. Great temps, limited RGB options but one is the TEMP setting, 1 of about a dozen. As you can see in the pic is idling green. Very pleased. This item was purchased from a return stock and was scratched up pretty good. Windex Vinegar, a paper towel and 5 minutes results in it looking new. The face of the sink was also dirty with old compound. Alcohol pads I use to clean my readers, perhaps 5 in total and some work and it came near new clean before installation. Very happy with it.So this is my 2cents on installation. I aligned mine so AMD could be read in the upper left side, assuming this was the intended orientation of the fan. This means the lock side is near the top of the board. I clipped the bottom ring on the AM4 plastic mount first and made sure the top side clip was in the extreme ‘relaxed’ position that is the latch allowing the clip to travel towards the board as much as it allows (play with a minute, get familiar). Then once the bottom was clipped on I sat the sink level and pushed (gently) while apply pressure on the top near the base where the square clip is moving it side to side slightly to align the hole with the plastic catch, I pushed harder on the metal clip than I did on the sink to avail the ‘click’ of the second clip. Once done, move the clip lever (black) at the top over to face the other direction, ‘locking’ the heat sink in place. This is a wonky procedure, but is not really all that hard.
Complete Buying Guide for Best Cpu Cooler For Ryzen 7 9700X
Essential Factors We Consider
When selecting a cooler for the Ryzen 7 9700X, the primary factors are thermal performance, noise levels, case compatibility, and budget. The 9700X has a 105W TDP but can draw significantly more power under heavy multi-threaded loads. A cooler should handle at least 150W of heat dissipation for comfortable headroom. Air coolers rely on heatsink mass and airflow; larger towers (like dual 120mm) perform best. AIOs use radiator surface area—360mm offers the best cooling but needs case space. Low-profile coolers trade performance for height. Also consider RAM clearance: some large air coolers overhang DIMM slots. Noise is measured in dBA; look for fans with PWM control and low-noise adaptors. Finally, ensure socket compatibility (AM5 is a must) and that the cooler fits your case’s dimensions.
Budget Planning
You can spend anywhere from $0 (using the included Wraith Prism) to over $200 on a high-end AIO. For the 9700X, we recommend budgeting at least $40–$50 for a decent aftermarket air cooler like the Thermalright Assassin X120. The Peerless Assassin 120 SE at ~$35 offers exceptional value. If you want top-tier air cooling, expect $50–$70. For a 280mm/360mm AIO, budget $100–$180. Remember to factor in potential additional costs like extra thermal paste or fan mounts. The sweet spot for performance-per-dollar is in the $40–$60 air cooler range.
Final Thoughts
The Ryzen 7 9700X is a powerful CPU that deserves a capable cooler. While the included Wraith Prism works for light use, serious builders should invest in a dedicated solution. Air coolers like the Thermalright Peerless Assassin 120 SE provide outstanding performance, silence, and value. For small builds, Noctua’s low-profile options excel. If you have the space and budget, a 360mm AIO like the Corsair Nautilus 360 RS delivers the ultimate cooling for overclocking and silent operation. Match the cooler to your case size, noise tolerance, and budget for the best experience.
Frequently Asked Questions
Q: Is the stock AMD Wraith Prism cooler enough for a Ryzen 7 9700X?
A: The Wraith Prism can handle the 9700X at stock settings in a well-ventilated case for general use and gaming. However, under sustained multi-core loads (like rendering or encoding), it will run warmer and louder than aftermarket coolers. For optimal performance, silence, and overclocking headroom, we recommend a dedicated air cooler or AIO.
Q: What size cooler do I need for the Ryzen 7 9700X?
A: For air cooling, aim for a dual-tower 120mm cooler (like the Thermalright Peerless Assassin) or a high-performance single-tower (like the Assassin X120). These provide ample cooling headroom. For AIOs, a 280mm or 360mm radiator is ideal for maximum performance. Low-profile coolers (under 70mm) will work but may run warmer under heavy loads.
Q: Can I use a low-profile cooler with the Ryzen 7 9700X?
A: Yes, but with caveats. Low-profile coolers like the Noctua NH-L9x65 can manage the 9700X at stock speeds in small cases with good airflow. However, they will run hotter and potentially louder under heavy loads compared to larger coolers. If you have a small form factor build, choose the best low-profile cooler you can fit.
Q: Should I choose air cooling or liquid cooling for the 9700X?
A: Air cooling is simpler, more reliable, and often quieter for the same performance tier. A high-end air cooler like the Peerless Assassin will match or beat many 240mm AIOs. Liquid cooling (AIO) makes sense if you want the absolute best temperatures, have a case that supports a 360mm radiator, or prioritize aesthetics. AIOs also help with RAM clearance. For most users, a premium air cooler is the smarter choice.
Q: Does the Ryzen 7 9700X come with a cooler?
A: Yes, retail-boxed Ryzen 7 9700X processors include the AMD Wraith Prism RGB cooler. However, as noted, it’s a basic solution. If you’re buying the CPU, plan on purchasing a dedicated cooler for the best experience, especially if you’ll be pushing the CPU hard.
Choosing the best CPU cooler for your Ryzen 7 9700X doesn’t have to be overwhelming. Whether you pick the unbeatable value of the Thermalright Peerless Assassin 120 SE, the convenience of the AMD Wraith Prism, or the extreme performance of a Corsair 360mm AIO, you’ll keep your powerful processor running cool and quiet. Consider your case size, noise preferences, and budget, then grab the cooler that fits your build. Your CPU—and your ears—will thank you.
