Thermalright AXP-90 X47 Full Copper Low Profile CPU Air Cooler with Quite 90mm TL-9015R PWM Fan, 4 Heat Pipes, 47mm Height, for AMD AM4/Intel LGA 1150/1151/1155/1156/1200

Bought this for the fractal terra case alongside the ryzen 5700x, under full load it can keep it under 80c

I too had to use pliers to remove one of the hex nut, just like other user. It comes with poorly designed back plate and stanoff for AM4 motherboard. Also 4x standoff with rubber rings are not touching the motherboard as a stopper.That's why when you tighten the backplate screws AM4 motherboard bends with it. ( Some users also reported the exact same problem ). I might return the product.

Paid for a new one but got a clearly used one. Screws are missing and there is clearly thermal paste remaining on the unit. Disappointed.

So if you can only fit a 47mm cooler into your AM4 system then the full copper version is the best performing cooler I have found by far, but it does have some issues. 1. It is not a cheep cooler, and for the price the build quality is not as good as the much cheaper and thinner Noctua. 2. The fan is unnecessary loud, I used the Noctua fan that came with my previous cooler, which is much quieter and has no noticeable loss in performance. 3. Mounting the cooler is a bit of a pain. It takes some juggling to get the mounting pressure firm enough for best cooling without bending the motherboard like a banana. However in my ultra thin micro ATX case that sits under my TV this cooler is worth about 100 points in cinnebench over the Noctua due to reduced thermal throttling.

The cooler was missing and the thermal paste was fully used, empty in the box.
