Thermalright AXP90 X53 Full Low Profile ITX CPU Cooler,with 92mm Slim PWM Fan for 2700RPM High Speed ITX CPU Fan,Pure Copper Version,for Intel LGA1150/1151/1200/1700/AMD AM4/AM5

I have descended into the molten core of thermodynamics itself to study this CPU cooler. I have read papers, haunted forums, communed with spirits of overclockers past, and emerged with one blazing truth: copper is not just 60% more effective than aluminum—it’s a metallic god among thermal conductors. Maybe the claims are real. Maybe they’re fake. Who cares. This cooler slaps so hard it could dissipate the heat of my existential dread. I slapped this copper beast onto a Ryzen 5800XT — a chip notorious on Reddit for running hotter than a GPU in a microwave, and guess what? Idle temps hover at 45–50°C, which is cooler than I was in high school. Under full load, this thing holds the line at 75°C like a war-hardened sentinel, refusing to let my silicon fry. Do I understand how? Not entirely. Is it witchcraft? Probably. Do I recommend it? With every fiber of my copper-cooled being. This isn’t just a cooler. It’s a temple of thermal management. A low-profile, high-performance, heat-slaying legend. Buy it. Worship it. Bolt it to your CPU and never look back.

Keeps 9800x3d cool in a Fractal Terra. Gaming temps top out at 80c maximum in CPU hungry games like BF6 and stays in the high 60's-low 70's for most other games. CPU has a -30 curve optimizer and while it will hit 95c in ycruncher/furmark, it does not throttle per HWInfo64 (5.25GHz the whole time) (this is with a quiet fan curve). I added a Noctua 90mm fan (not that the stock one was excessively loud) and the noctua foam duct kit in order to optimize temps. However the stock fan with no foam duct was also fine. For reference I am using a Gigabyte 9070xt Gaming OC edition (132mm tall and 56mm thick) in a Fractal Terra and the spine is in position 4, which allows for enough space for the CPU cooler and GPU to not create turbulence.

Performance is admirable and the noise levels aren't too shabby either

Using in a FLP01 silverstone case on a 5700g with no gpu. In a low flow enviroment (3 120mm case fans and this cooler being only fans in that case) it works amazing. Running prime 95 for 5 hours it maxed out at 71.5C idling around 63C. I only bought this for its low profile, but I will very much be coming back for its performance. The only reasons it gets 4 stars is due to the lack of spacers and sub par thermal paste. I have used this same paste before, and it seems to harden after a year of occasional usage. I would reccomend getting an alternative paste. You have a few bare bolts going through the motherboard to the back bracket. This makes it very easy to over tighten. Im fine living with it, bit I am sure some spacers could be found at a local hardware store. Over all, very worth it for the solid copper (if it is real copper) and great specs.

paired this with a ryzen 3800x 12 core cpu in 65w eco mode that i use as a media encoder / streaming pc in a 2u rackmount. good build quality. fan is very quiet.

Best tiny cooler for the money I have it on my 7900x3d keeps it 70c under gaming load. Inside a terra with a msi gaming x slim 4090. I had the Thermalright AXP90 X47 copper its a good cooler but it would keep my 7900x3d 82c under gaming load which isnt bad but the Thermalright AXP90 X53 Full is better if you have the space. I replaced the red fan with a white and it looks sweet.

If you HAVE AN AM5 CPU, DO NOT GET THIS BECAUSE THE MOUNTING INSTRUCTIONS WON'T APPLY TO YOU, SINCE THE BACKPLATE ON YOUR BOARD WON'T BE REMOVABLE (AM5 BOARDS DO NOT HAVE A REMOVABLE BACKPLATE). DO NOT GET THIS FOR AN AM5 BOARD OR YOU WILL MOST LIKELY DEFINITELY BE SORRY. I AM SERIOUSLY JUST TRYING TO HELP. IN ALL FAIRNESS, I WILL ADD THAT I USED ANOTHER OF THEIR COOLERS AND IF WAS PERFECTLY FINE (AXP120-X67), so the problem seems to lie with just this one product. My guess is they have a lot of precious copper heatsinks leftover and they can't really sell them since AMD made AM5 with a non-removeable backplate, but I could be wrong.

Easy install for AM5 Good temps on my 7600X Idle temp. mid 40s Celsius Very cool look as well with the orange fan blades and copper heatsink Pretty quiet as well, I have on silent mode.

The heatsink started to rust idk why

Bought this last month and waited for around 10 days before it arrived only to find out that there were parts that were missing like the thermal paste, the screws to hold them and a few brackets. Returned it right away. Ordered a new one hoping its complete now.
