Customer Reviews
Customer Review: Performance is superb. Switched out my “mushroom” style stock cooler on my 12th gen i7. Idle temps dropped from 50c to 39-40c. Under 100% load it reaches about 52c, which is fantastic compared to the stock cooler that was giving temps of over 70c under full load. Fan is whisper quiet, perfect fit for an lga 1700 CPU, installation is easy if you already have a backplate, otherwise you have to take out your whole motherboard to attach it to the rear. Looks great in the case. Took me about 15 mins to install ( had to remove a proprietary backplate to install, overall pretty easy ). For the cost, its a great buy.
Customer Review: Grabbed this cooler on a whim and impressed by it so far. Threw it on a 12600k in an ITX build. Very happy with the results – keeps it around 58*C under an all-core stress test for a couple of hours. Really impressively for such a budget cooler.Aside from performance, the other thing I’m impressed by is volume. The fan is one of the more quiet ones I’ve heard – or, not heard? Cooler looks great, too. All black is always in.Careful though: the fins are ridiculously sharp. I sliced my thumb and now I guess I can say there are literal blood, sweat and tears in this system. Good news is that you don’t actually need to risk life and limb since the fan comes pre-installed (I switched orientation of mine due to the ITX case).Honestly one of the best performing budget coolers I’ve ever used.
2. Thermalright Peerless Assassin 120 SE CPU Cooler
The Thermalright Peerless Assassin 120 SE is a dual-tower legend that consistently tops performance charts. With six heat pipes and two TL-C12C PWM fans, it moves a massive amount of air while staying surprisingly quiet.

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.Additional Recommendations:The thermal paste that comes with the package is ok, but I would highly recommend buying a high quality NON CONDUCTIVE thermal past.(Thermal Grizzly Kryonaut, Artic-mx4, Cooler Master MasterGel Pro v2 etc)This is important!Make sure its NONCONDUCTIVE. Some thermal paste uses metallic ingredients to aid in thermal conductivity. The problem with this is that if you apply too much, it can go into the cpu electronic components and damage your system. With noncoductive thermal paste, this isn’t a issue so you don’t really need to be too exact. (If its a little too much, it doesn’t hurt anything.)This Air cooler also comes in single or double tower configurations, if your case can support it, I would definitely get the double tower.Make sure you get the fans installed/oriented correctly.I would also recommend installing cpu temperature monitoring software as well to make sure that everything is working correctly. I would definitely recommend this to anyone who wants a very reliable and very affordable air cooling option.
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.
3. Thermalright Assassin X120 Refined SE CPU Air Cooler
When your budget is razor-thin, the Thermalright Assassin X120 Refined SE is the undisputed champion. It’s a single-tower cooler that punches way above its weight class. For the price of a fast food meal, you get a capable AGHP heat pipe cooler with a quiet PWM fan that will demolish any stock cooler. It’s the go-to recommendation for budget builders and office PCs that need a quiet, reliable upgrade.
Key Features That Stand Out
✓ Incredibly Low Price without sacrificing build quality
✓ AGHP (Anti-Gravity Heat Pipe) technology for consistent performance
✓ Compact Size fits in almost any case

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.
4. Dual-Tower CPU Air Cooler
This dual-tower cooler is a fantastic alternative to the more famous Thermalright models. It packs six copper heat pipes and two high-static pressure ARGB PWM fans into a relatively compact design. The dual-tower setup provides a huge heatsink surface area, and the 2000RPM fans ensure you have headroom for even the hottest CPUs. The ARGB lighting adds a touch of style without being overbearing.
Key Features That Stand Out
✓ Dual-Tower with 6 Pure Copper Heat Pipes for massive cooling potential
✓ Two 120mm ARGB PWM Fans with 2000RPM speed for strong airflow
✓ Wide Compatibility with Intel LGA 115X/1200/1700/1851 & AMD AM4/AM5

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. Tried reseating the CPU, swapping RAM, checking cables, you name it. 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 that blends nicely into my case. Honestly can’t believe this solved the issue, but I’m glad it did.If you’re building with a high-end CPU like the 12900KS and running into weird stability or boot issues, don’t overlook cooling. This thing just works.
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 that I didn’t want to use the system for more time than necessary. I was not sure which fan was making all the noise but with a tooth pick narrowed it to the CPU fan.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+ directions with basic stepsNot as good:- Installation took me about 90 minutes (I don’t do this daily… so I am a bit slow)- If you’re reapplying thermal paste you need 99% alcohol to clean the old paste (not included)- Installation required removing my system board- not a huge deal but takes time (case didn’t allow access to under the system board) So this could be because I have an older case. Be ready.- If you have a small case it may not fit… check the case size, it’s tall. Mine is full size Lian-Li and fit nicely.- second fan not included but can be added.- second fan may be tight against the memory on your system board.- split cable to power the first fan and add a second fan made my cpu fan speed unreadable. I added it so that the cable would be there for a future second fan.All in all, I like this solution. It’s very quiet, inexpensive and working nicely.Happy Computing!
6. Thermalright Assassin X120 Refined SE ARGB CPU Air Cooler
This is the ARGB sibling of our Best Budget pick. It’s identical in performance to the non-ARGB version but adds a vibrant addressable RGB fan for builders who want a bit of light show. The performance remains stellar, and the fan is just as quiet. If you like the Assassin X120’s value but want some customizable lighting, this is the one to get.
Key Features That Stand Out

Customer Reviews
Customer Review: This is without a doubt the BEST budget cpu cooler you can get. It SIGNIFICANTLY reduces temps compared to the factory wraith cooler. It just plain works. My temps are much more regulated, the fan is surprisingly quiet (BeQuiet! is still quieter). Looks great, actually matches my stock case fans almost perfectly. Very easy to install, just torque down the bolts in a cross pattern. Overall, fit and quality is great. Love this thing.
Customer Review: The Thermalright Assassin X120 R SE is so good. It’s inexpensive, isn’t the most difficult to mount on an AM4 system, is quiet, and keeps temperatures super low while the CPU is under load. I installed mine onto a B450 board with a 5600G. Compared to the Wraith Stealth during a Cinebench R23 benchmark, 10-minute run, temperatures on average were 19+ degrees C cooler with the Thermalright Assassin X. The ARGB fan is nice and sturdy and while only 8-leds, it’s plenty bright and very quiet at idle speeds.For the cost, the performance is out of this world. I’m unsure how well this cooler will perform on higher TDP CPUs (5600G is only 65W), but I definitely recommend it.I took a couple of stars off for the mounting system/ease of install as the brackets are a tad fiddley. I highly recommend installing the cooler before you put the motherboard into your PC Case. As I was replacing my cooler, my mobo was already installed, so it was a bit more difficult than I liked.Other than that, this is a great product for those looking to get better temperatures for not a lot of money! A+++

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. If you are building a new computer, this is much easier to install and more reliable than an AIO water cooler.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.Note: you should prefer this over the 120 EVO. Yes, the EVO has RGB and can get you a couple of degrees cooler on higher TDP processors, but at the cost of much higher noise. If you’re using anything less than 170watt CPU, this is probably the better choice.Addendum: now using this on two computers. Zero regrets.Addendum: this cooler does make it more difficult to replace the M.2 drive without removing the cooler. Not impossible, just obnoxious.Addendum (November 2024): started getting obnoxious fan noises about a half year later. Thankfully, there are a variety of fans you can replace these with that will produce reasonably similar performance, including the Arctic P12 or the Noctua NF-A12x25 (the latter being about as expensive per fan as this entire cooler with included fans).
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. This is a testament to its excellent thermal management and efficiency.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!

Customer Review: This cooler was incredibly easy to install onto my motherboard and does a great job of keeping things nice and cool. It’s not too loud, the included fan isn’t blazingly bright, and is overall a very sleek and useful cooler. One thing I will note to everyone is to be extra careful to not bend any argb pins on your board while installing this or any other kind of fan (Speaking from experience.)

- AGHP technology works well
- Good value for the unique feature set
Cons:
- Display software can be a bit clunky to set up
- Fan can get louder at higher RPMs
- Display may not sync with other RGB software
Customer Reviews
Customer Review: It does the job and looks good. For only $20 it was not as cheap feeling or looking as expected. I was very surprised. Very quiet at 40% (using fan control) and keeps temp around 30c at idle (stock cooler at idle was 45c). I am running a ryzen 5 5600XT 65w cpu. When boosting the cpu can pull 95w. Even keeping the fan at 40% my temps are around 50c at 100% load. Keep in mind that I have 5 intake and 3 exhaust case fans, so tons of airflow around it. I would recommend. Setup was straight forward. It used the stock AM4 backplate so there was no need to pull the motherboard. On initial setup the display just stayed static on the temp it read during startup. I had to go into the program and set it to one of the cores to have a real-time readout displayed. The fan is argb so of course that was just connected to my hub so it worked with signal rgb. The display was not picked up by signal rgb but is customizable through the downloaded software.
Customer Review: Solid value for the price. It’s quiet, keeps the cpu cool and looks good.
10. Thermalright Peerless Assassin 120 Vision MAX ARGB White CPU Air Cooler

Complete Buying Guide for Best Cheap Cpu Air Cooler
Essential Factors We Consider
When choosing a budget CPU air cooler, we prioritize cooling performance per dollar, noise levels, build quality, and compatibility. A great cheap cooler must effectively lower temperatures without sounding like a jet engine, fit in your case and on your motherboard, and feel durable. We also look at the heat pipe design (AGHP is a big plus for consistent performance), fan quality (PWM control is key), and whether it includes necessary thermal paste and mounting hardware.
Budget Planning
You can get excellent cooling for $20-$40. The $20-$30 range is where the true value kings live (like the Assassin X120), perfect for 65W-105W CPUs. Spending $35-$50 gets you dual-tower or high-end single-tower performance capable of handling 125W+ chips. Avoid the ultra-cheap (<$15) no-name brands—their performance and longevity are often questionable.
Final Thoughts
The market for cheap CPU air coolers is better than ever. Brands like Thermalright have redefined what “budget” means, offering performance that used to cost twice as much. You don’t need a liquid cooler for a great build. A top-tier air cooler is more reliable, often quieter, and provides peace of mind. Our top picks prove that you can have exceptional cooling without the premium price tag.
Frequently Asked Questions
Q: Can a cheap air cooler handle a high-end CPU like an i9 or Ryzen 9?
A: Yes, but with caveats. Models like the Thermalright Peerless Assassin 120 SE or Phantom Spirit 120SE can handle high-end CPUs at stock speeds or mild overclocks. They will keep temperatures within safe limits, though they may run warmer and louder than a high-end AIO under extreme, sustained loads. For heavy overclocking, a more robust cooler is recommended.
Q: Is installation difficult?
A: It varies. Coolers with a backplate (like most Thermalright and Cooler Master models) often require motherboard removal for the easiest installation. Some, like the DARKROCK PX4 or Assassin X series, can sometimes be installed with the motherboard in the case if your case has a cutout. Always watch an installation video for your specific model first. The process is straightforward but requires patience and care.
Q: Do I need ARGB lighting?
A: No, ARGB is purely aesthetic. The non-ARGB versions (like the standard Assassin X120 Refined SE) are often cheaper and perform identically. Choose ARGB only if you want your cooler to sync with your system’s lighting and you have a compatible motherboard with a 5V 3-pin ARGB header.
Q: How loud are these budget coolers?
A: Most modern budget coolers are surprisingly quiet at idle and moderate loads. The DARKROCK PX4 and Thermalright Assassin X series are known for near-silent operation. Under heavy load, all fans will become audible, but models with better fans (like the TL-C12C) maintain a tolerable hum. Look for coolers with PWM fans so they can slow down when temperatures are low.
Q: What thermal paste should I use?
A: The paste included with these coolers is usually decent for a first-time application. However, for the best possible temps, we recommend a high-quality non-conductive paste like Thermal Grizzly Kryonaut, Arctic MX-4, or Cooler Master MasterGel Pro. Apply a pea-sized dot in the center of the CPU—the pressure of the cooler will spread it evenly.
Finding the best cheap CPU air cooler is about balancing your CPU’s needs with your case size and budget. From our testing, the DARKROCK PX4 is the top all-around pick for its quiet performance and wide compatibility. For the absolute best performance-per-dollar, the Thermalright Peerless Assassin 120 SE is unbeatable. And if your budget is extremely tight, the Thermalright Assassin X120 Refined SE is the undisputed budget king.
Don’t overthink it. Any of the coolers on this list will be a massive upgrade over a stock cooler and will serve you well for years. Check the price on your favorite model today and give your CPU the cooling it deserves without emptying your wallet.
