Works like a charm. Good buy easy to install


Stephanie Seagraves

The box of the product does not specifically indicate AM4, but it does work. Quiet, efficient. Excellent value.


Jose Enrique Romero Marte

Works pretty well with ryzen 5 3600, won't pass 60°c while gaming


Chris V

It brings about 3 different brackets depending on your board & some thermal paste.It's been great at cooling, so I don't have any complaints.Aesthetically? It's pretty average, but I see it as an extra feature to the cooling.


Logan Jackman

I have a AMD Ryzen 5 3600 CPU and it hit 95 degrees C while gaming. That’s insanely hot so I bought this and now the maximum that I have hit was 78 degrees C. That’s a 17 degree difference. Would definitely recommend. It was a little weird to install but once I got it on there it worked great



I Bought this because it said its said GAMMAXX 400 is for AM4 Compatible. Turn out to be wrong..It does not come with AM4 Bracket.My CPU is Ryzen 2600 come with Default Cooler (Wraith Stealth Cooler) which does not use Socket Retention Mounting Bracket. *It just screw onto motherboard like how Intel*.EDIT: Bought AM4 Retention Bracket. Good Cooling and Quiet. just hard to put on a case. the fan to install kinda pain in the once you install the Heatsink first. (i did not take out the motherboard from PC..While Playing WoW. CPU stay cool at 44 Degree Celsius.You will need to buy a Socket Retention Mounting Bracket AM4. The Wing Clips don't match the length for AM4. They are for Intel. there is AM4 hook type but does not include a AM4 Retention Mounting Bracket.



Only drawback is that it can be a pain to mount but that's to be expected from a cheaper cooler that might not be built to perfect spec.Function is amazing. I'm running with dual fans in a well ventilated case and my 3600X with PBO enabled tops out at 75 degrees at the highest Prime 95 load while cooling back down almost instantly the minute I stop the test. If you want a super efficient air cooler that also looks pretty good on the cheap I highly recommend this.Also yes, I know the photo I uploaded has the fans backwards but I've since noticed and fixed it. I think I was tired the night I mounted it and didn't pay attention to the direction.

The only downside of the entire thing is the instructions were slightly unclear to read but I figured it out. All together it's it's quiet and keeps my CPU cool for hours.


Seth M. Dudley

I used this CPU Fan/Heatsink to upgrade from an older stock AMD cooler.It made a massive difference in noise, thermal levels, and has a pretty cool blue light. It was fairly easy to install since it didn’t require a new backplate but did take some muscle to get onto the AM3+ socket properly.My only complaint/warning is buyers should order thermal paste along with this cooler. It does come with a VERY SMALL amount that was barely enough for my install. It’s possible I just had an older/dried out packet but it wasn’t great. I might have to order more and do a fresh install.Besides that, great value for the $25 it cost.



OK, so this isn't rocket science or anything out of this world. Its a cooler, its cheap and it WORKS. I placed this on my AMD FX 8350 that had the old stock cooler on it. Went from 38c to 40c idle to 22c to 23c idle with the new cooler (I also added a fan as well). It is quiet, efficient and didn't rape my wallet. So I am happy and I do recommend it. PLUS it comes with an extra set of fan clips! The instructions are on the inside top flaps. Again, not rocket science. I can't say anything if you are a Overclocking crack addict, but then again, that's what water cooling is for. No regrets, buy it.



Took my i5 8400 from 80c (stock cooler) to 57c when gaming. Love it for the price


Richard W. Morrison

Excellent cooling for such a price. FX 8350 CPU now temperature average about 30 degrees instead of 76.



I bought this for the crypto miner in the picture. Without modification it wont work for this purpose.That said my computer just got an unneeded CPU cooler upgrade.Was not a fan of the stock fans color/ noise, but have a box of red thermetake’s that popped right on. And the out of box support for 2 fans was actually dope af.The intel plastic mounts are wobbly and difficult to install but with a few shots of bourbon and much cussing the manufacture they eventually popped in.Overall satisfied with the product and the results the cpu does run about 15-25 degrees C under load vs stock cooler.



Its quiet and keeps my cpu at 30C when idling.



I installed this cooler as an upgrade. Installing with the motherboard mounted in the case is a pain. It would have been much easier to install with the motherboard outside the case.


samuel freeman

Easy install quick shipping highly recommend


Michael Carpenter

Awesome makes everything look really clean



Bien de bien


Corey b.

Works very well. Its worth the money for sure, and a lot quieter than I had imagined it would be.


Don kash

My old rig was running a 8150 with a stock cooler on a 890fxa gd70 and after about 9 years it finally started to fail. I ended up grabbing this product and have already noticed better results with temp and sound. Great solution for old cpus at a great price
