Review: Great cooler, performs how you'd expect! - It cools amazingly, it's easy to install and remove for maintenance and cleaning, and honestly, it looks great too!
Review: Really impressed at the value you get for the cost. Looks good too - I didn't have too much trouble installing this cooler. The instructions were pretty clear, despite not using many words to describe each step. It's a little meticulous but nothing out of the realm of expectations. I am using this on an i5-12600K overclocked to 4K. At idle its about 30C and when using the Passmark burn test it maxed out at 68C. Never felt hot to the touch. The fans are held on by clips so you can arrange them however you want (both outward, both same direction, etc) The order I chose may cool one side more than the other, but I'm not concerned with minor variance between the two. Obviously you cannot attach a fan in the middle until you screw it onto the board. Order of operations matters. Shown here in a Jonsbo Z20 mATX case.

### ⭐⭐⭐⭐⭐ May well be the best value CPU cooler
*by P***R on September 3, 2024*

I have an i7 13700K cpu, which is known for hot running, and was using a NZXT T120 cpu cooler. The NZXT T120 was quite decent, but temperature could reach the 100 C max under stress. It should be perfectly fine, but I do want more margin. This Thermalright is so inexpensive that I have to give a try, especially given the many positive reviews. BTW, I had considered AIO, but the additional complexity and potential for failure made me dropped the idea. It arrived promptly. It is massive compared to the NZXT, which is not small already. I spent quite a bit of time to understand the installation process. It was a good thing I did that. The installation is not complicated, but the planning helped to speed up the process and eliminated many potential mistakes. It only took me may be 10 minutes from removing the old cooler to finishing up the installation of the new cooler. Now the performance. Idle temperature is just a couple degrees above ambient. Max temperature barely reached above 90 degrees under synthetic stress test. 80 degree was about the max under normal stress, which is photo editing for my case. In terms of noise, it is quite quiet imo. It seems to live up to expectations. Given the price, it is highly recommended.
