Review: Good price, easy to install, works brilliantly. - Swapped out an Intel stock cooler with this and I gotta say, the temperature difference is truly striking. From averaging around 50c on desktop and around 70c under load (playing games, using heavy software) to 30c-35c on desktop and no more than really 45c-50c under load is really amazing. Can't stress enough that the cooler comes with everything you need (brackets, screws, back-plate, radiator and fan) especially since it's compatible with intel or AMD and for the price? I seriously doubt yours gonna find a better cooler for the cost of this one. The install is relatively simple, video on this page is super helpful if you need it but instructions come in the box. TL;DR, Its a great cooler. Really good price, easy to fit and looks nice. Can't ask for more than that.
Review: Performance to price ratio is through the roof! - Have used a few Thermalright products previously but usually the larger ones such as the peerless assassin, but needed something as cheap as possible as the cooler I was using (AMD Wraith Prism) in this build just wasnt doing the job. For the price I really wasnt expecting much but everything was up to the great standard I have come to expect from TR and this functioned above my expectations! CPU temps were nearly 15 degrees cooler at full load (had replaced thermal paste previously with no improvement), was nice and easy to install and felt sturdy once it was on. I always worry these tower coolers wont fit and this was a relatively slim case but there was plenty of room and it looks fantastic. Would absolutely recommend this for mid range CPUs. I wasnt seeing much above 70 degrees on a 5600X which considering I was seeing up to 85 before, which impressed me - especially at this price point!

## Questions & Answers

**Q: has anyone added a 2nd 'pull' fan to the back of this? are there mounting holes/screw slots to facilitate?**
A: it comes with a second set of fan clips so any standard 120mm can be clipped on. I had a left over fan from a hyperX 212 worked a treat.

**Q: Does the thermalright ak120 se support AM5?**
A: Dear customer:

Our radiator supports the AM5 platform.

### ⭐⭐⭐⭐⭐ Fan Tastic
*by A***3 on 7 December 2025*

Good performance on my Ryzen 5800G. However I decided to fit an extra PWM fan on the rear of the heatsink fins with the extra clips provided in tandem with the original fan. Fairly quiet until the upper reaches of CPU temperatures when pushing my system on some games. Quality made by the looks of it and an economical price tag.
