140mm fan to Thermalright AXP-120 x67 mounting solution

Hello all,

this is my first contribution to any 3D print database service, because I thought that my trouble in finding a fixing mechanism for a 140mm fan, and my solution for it might help also others. Came across the Fractal Design Ridge case and wanted to have a solution to keep it cool, even if the height of the CPU cooler is restricted to 70mm including the fan. Tried Noctuas NH-L9x65, beQuiet Shadow Rock LP and the Thermalright AXP120-x67. Sticked with the Thermalright, because it fitted best with the I/O shied of my motherboard. Tried the 120x120x15mm Noctua fan, which gave better results as the included Thermalright fan, as it moves a bit more amount of air, as the Thermalright. Looked into the case and found out, that also a slim 140mm fan should fit without issues, but no clean solution possible here, except for zip ties, which I didn't had a good point to fix the fan to.

So then looked around, saw some ideas from others and created a rough fan bracket by myself at the end, which just clicks onto the already mounted AXP120 nicely. The long mounting "legs" need to head to the PCI-E slot, and the "thinner" leg part to the fan connectors. Does perhaps not meet some visual requirements some may have, but does the trick and you don't see it anyway in the case.

I used also the screws with the finer threads, that came with the Silverstone 140mm slim fan, to mount the fan onto the bracket.

If you happen to have a FD Ridge case and want a mounting solution for your AXP120, then this might be useful. Buy these:

1. Thermalright AXP120-x67
2. Silverstone Air Slimmer 140mm Fan

Print with min 50%, better 100% infill, as you need a bit rigidness for the printed part to stay on the cooler. I have used PLA matte from Anycubic. Temperature wise and in the long run, I might want to print out another one in PETG or ABS in the future. No support needed.

I use it with an ASUS B560I Motherboard, Intel i9-11900KF CPU. The i9 can still get to nearly 97° C/ 200-210°F, but the cooler itself won't reach those temperatures. Recommended is also to restrict the i9 to around 180w Turboboost short term, and 150w long term. That works quite good. If you are an overclocker, don't go with the Ridge, if you also use a potent GPU and can not use the space for an AIO 240/280 😉😄

Update 30.12.2025: I do not have the ridge anymore, sold it as it was. So I can't modify without measuring. Please use as it is or modify the stl by yourself. Did this with tinkercad so no stepfile available.
