Cooling Thermalright AXP 120-X67 Cooler Performance

[Mark13]

I decided to test out the new Thermalright AXP 120-X67 low profile downdraft cooler on my Maker Beam test bench bench cooling the Ryzen 7 4750G Pro APU without a graphics card. The cooler was very nicely built - cold plate has a very smooth finish. The fin direction is turned 90 degrees from the Noctua and the Blackridge coolers. Unlike the Noctua it does not include a second set of mounting brackets for AM4 to allow the cooler to be rotated in 90 degree intervals. I chose to mount the cooler over the RAM as I use Corsair LPX memory that has plenty of clearance and I preferred to have the cooler not over the IO section of the motherboard. It uses the standard AMD backplate making the cooler as easy as the Noctua to install. Thermalright also includes fan clips for both 15mm & 25mm thick fans. I did earlier testing with this exact configuration with both the Noctua L12 Ghost Edition, and Alpenfoehn Blackridge CPU coolers with both 15mm and 25mm thick fans. The lower fan from both coolers was removed from both for those tests. I consolidated the testing results from my earlier testing with those of the Thermalright cooler for an easier comparison. You can see from the photographs as to why the Noctua is mounted with the Thermal Grizzly Carbonaut Thermal Pad - it fused to the Noctua cold plate on its first use - so I continue to use it in this manner. The GPU and the case fan in the photos were removed prior to testing.

Thank you for the great post and info, would you be able to mount 15mm fan under the heatsink with the AXP 120 just like the blackridge + VLP ram ?

No, there is no space to mount a fan underneath - the heatsink is built out in the middle on the underside.

Can you still measure the distance there? Maybe some bending might free some space.

I took another look at the cooler and there does not appear to be a way to mount even a 92mm fan underneath. First there is a support bracket from the front of the cold plate up to the bottom of the central portion of the fin stack that would have to be removed. Second, the central portion of the fin stack extends down approximately an additional 7mm across most of the length & width of the cooler and this portion extends over the 2 cooler mounting screws that attach to the mounting bars, with only about 4mm between the bottom of the fins and the top of the 2 cooler mounting screws. You will need to look elsewhere. I am still very impressed with this cooler if you have the space.
