Been using this cooler on one of my PC`s - Cooling a Ryzen 5700x no problem - Low 60`s in Game

ID Cooling is best value for money

I'm using this cooler in an ITX case running Intel Core i3-9350KF (95w TDP) on a Supermicro X11SCL-IF. Before purchasing this cooler, I was using a Noctua NH-L9i. It simply could not keep up, every now and again the CPU would hit PROCHOT (100℃) and would average 50℃. With the IS-55 my idle temperatures have dropped to 35℃ and I haven't exceeded 60℃.

Would definitely recommend this cooler, especially at this price-point, you get a lot for your money

Solid construction, nice low profile, cools my i5 mini-ITX Kodi box at least as well as my liquid cooler used to.
Fits nicely onto the MSI H8i board, even with my full size RAM with heat spreaders.
Very quiet and CPU temps remain in the desired range.
Definitely recommended.

And they say size matters ;)

Outstanding cooler considering its low profile. It works very well on higher core count chips at lower TDP's, and even with the high heat density of chips like the 5800X3d it still managers to hold up well and keep temps in check under all-core workloads.

When you consider that this is as cheap as it is, it makes it a no brainer - for anyone building an SFF system, if your RAM is at a compatible height just buy this and don't think twice.

Using it to cool my Ryzen 9 3900 with the power limit set to 115W. The processor doesn't go past 80 degrees celsius after running a CPU-Z stress test for about an hour.

Low profile and quiet, keeps cpu cool. Difference between this and a stock amd am4 cooler is quite noticeable when it comes to sound and cooling performance.
