DeepCool AK620

The Thermalright Peerless Assassin 120 SE has honestly been one of the best upgrades I’ve put in my PC. I’ve been using it for a while now in my setup, and the performance has been amazing for an air cooler in this price range. It keeps temps low and stable even under load, and it just quietly does its job without any drama. The dual 120mm PWM fans move a lot of air while still staying fairly quiet, and the 6 heat pipe design really seems to make a difference in heat dissipation. Installation was straightforward, and it’s been fully reliable across long gaming and everyday use sessions. It also fits a wide range of sockets, which made it perfect for my setup. Overall, it’s easily one of the best or the best value cooler out there.

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 Affordable Cools very well Very well made Package 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.

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.

When I built my PC five years ago I installed a Dark Rock Pro 4 for my CPU cooler. It worked very well, but over the years the fans grew louder, the cooling became less efficient, and dust began to accumulate in hard to clean places. I decided to look for an affordable replacement and settled on the Thermalright Peerless Assassin. Overall, I believe this was a very good choice. Compared to my Dark Rock Pro 4, the Thermalright Peerless Assassin was a breeze to install. The LGA 155x bracket fit my motherboard and was easy to install. The thermal paste seemed thicker than other pastes I've used, but it went on neatly and is clearly working. The spring screws seem to have secured the cooler to the brackets very well. My biggest complaint with my old cooler was installing the fans. Happily, I can report that the Peerless Assassin's fan are easy to install, and remove if needed, and are secure. In terms of performance, I'm completely satisfied. The fans are not as quiet as my Dark Rock Pro 4 when I first installed it. However, they are an acceptable low volume. My PC has an Intel Core i7-8700k CPU and the cooler has no problem keeping it between 20C to 30C while idle or under a light load. I am no longer an avid gamer, and do not play modern video games, however I did test the thermals while playing Minecraft. It kept my CPU around 40C most of the time and would briefly shoot up to 50C when loading parts of the map. At less than 40 USD this cooler is a fantastic option for CPU cooling. Its significantly less expensive than comparable coolers, is easy to install, and delivers good performance.

This cooler does an excellent job keeping temps under control. Even during heavier workloads, it handles heat really well and keeps everything running stable. For the price, the performance is honestly impressive and competes with much more expensive options. That said, installation took a bit more patience than expected. The mounting process isn’t difficult, but it can feel a little awkward, especially in tighter cases. Also, make sure you have enough clearance for RAM and your case, since it’s a fairly large cooler. Once it’s in, though, it’s solid—quiet, efficient, and reliable. If you don’t mind spending a few extra minutes on setup and double-checking fitment, it’s definitely worth it.
