Not just for Ryzen mother boards. Words find on my ASUS 88x.

So far it has been pretty solid...Dropped my temps on my CPU by ~10+ degrees (I was previously using the wraith stealth that came with my Ryzen 5 3600, which is the bottom tier of the AMD stock coolers). As I stated above you need the two small retention brackets that the cooler hooks on to mount this cooler so if you get this cooler make sure you get those as well. Luckily I believe the brackets came with my 3600 even tho the wraith stealth does not used them. It did come with thermal paste pre-applied but it did not coming with any instructions on how to mount although you can easily find a youtube video/instructions online to figure it out. Also there is a small Low/High switch on the cooler itself, I recommend starting on low unless you needed it on high because high is very loud. I switched back to low which is much better but still has random ramp ups where it gets noticeable even with just doing internet browsing. If you game with a headset it mostly wont be a problem but if you absolutely want your fans quiet you may want to look somewhere else or Ive heard there is software to control the fan curves which I havent gotten into yet. The RGB is nice and easy to control using the cooler master software. I use a USB header to control the RGB although you can also the 12V RGB header but it may need a different software.

Update: the cooler didnt cool as well as I initially thought, it started out good and did do better than the cooler I had but still wasnt doing a great job at keep temp where I wanted them. And the noise was better but still quite noticeable. Im going to return this cooler and get a Noctua cooler, from the reviews of the Noctua it should greatly help with both my temps and noise and im willing to pay the difference in cost to solve those problems.

Ordered this to use with an R5 3600 build in a micro case I'm putting together. Due to the small case size, I was limited on size of the cooler but wanted a bit more than the wraith stealth could offer without going over the top with an AIO. This cooler came packaged in the box it came in with its original processor. This is from a higher end Ryzen processor, this is not a retail item. This is not an aftermarket cooler. That being said, it came to me unused and packaged exactly as it is in a higher end Ryzen box. The original thermal paste was intact and appeared unused on the cooler and it came with all necessary cords. It also came with a small syringe of thermal paste in the box. The cooler did not look damaged and was pristine out of the box. I'm not sure why many reviews state the cooler looks damaged, used, etc unless I got lucky and got a legitimately unused one. No instructions for the RGB control are included (and aren't normally), so google is your friend there.

it work

This cooler runs my 1600AF chip at 25 degrees C at idle. I know, when I was a child in America my teachers taught us the decimal system and promised us that when we were their ages, the US would have standardized the Metric system. Four pin Fan power and then optional connectors 4Pin ARGB or 3 pin to USB header. The 4 FAN is hard wired in and the two ARGB or USB header (9 pin USB 2.0) are optional to provide the illumination and control. Great temps, limited RGB options but one is the TEMP setting, 1 of about a dozen. As you can see in the pic is idling green. Very pleased. This item was purchased from a return stock and was scratched up pretty good. Windex Vinegar, a paper towel and 5 minutes results in it looking new. The face of the sink was also dirty with old compound. Alcohol pads I use to clean my readers, perhaps 5 in total and some work and it came near new clean before installation. Very happy with it.

So this is my 2cents on installation. I aligned mine so AMD could be read in the upper left side, assuming this was the intended orientation of the fan. This means the lock side is near the top of the board. I clipped the bottom ring on the AM4 plastic mount first and made sure the top side clip was in the extreme 'relaxed' position that is the latch allowing the clip to travel towards the board as much as it allows (play with a minute, get familiar). Then once the bottom was clipped on I sat the sink level and pushed (gently) while apply pressure on the top near the base where the square clip is moving it side to side slightly to align the hole with the plastic catch, I pushed harder on the metal clip than I did on the sink to avail the 'click' of the second clip. Once done, move the clip lever (black) at the top over to face the other direction, 'locking' the heat sink in place. This is a wonky procedure, but is not really all that hard.
