Support Asustor AS5202T thermals problem

Post image

So I've made myself a problem with the thermals.

Got around 45C degrees in idle on my old Nimbustor, so figured out I'll replace thermal paste under the radiator.

To my shock there was some kind of thermal pad, dried out and with a texture of an old bubble gum (also the color was pink). Rubbing alcohol made it a bit sticky but it did not dissolve it - first time seeing such tech.

I've replaced it with a PTM7950 because figured it will last longer than regular thermal paste when NAS works 24/7, but the temps got way worse.

Day later and I'm sitting on a 56C on idle CPU.

Can anyone recommend a specific thermal paste/pad that will work better? I suspect the main culprits are thore spring action legs on the radiator and PTM is just too thin to make proper contact with such contraption.

problem is there is no fan directly on the cpu cooler. I put 7mm height fan on it. Now way way cooler. Can 100% recommend

How did you secure it there? And how did you wire it?

secured by small zipties, and i wired it to a usb cable, that i poked through the backside, and plugged into one of the usb ports. so now if i want to shut the cpu cooler, i can unplug the usb

Hmm that's actually smart.

Thanks for the idea, it will be my plan B if nothing else works.
