After about one year of 24/7 operation, the CPU fan started make weird/loud noises, like it's about to fail within the next months. So here is my take on the "Noctua fan mod".
Required Equipment:
- Noctua NF-A6x25
- Zip ties
- Thermal paste
- Screw driver
- Pliers (to cut the zip ties)
How to: as in the pictures
It's easy to do, it took me about 2h from shutdown to boot, including removing the necessary parts from the chassis, cleaning, etc.
The fan is held in place very firmly. The zip ties on the side are held in place by the outer fins, because they are in the shape of a hook.
As a side-effect, average temperature has also improved. This could be because of the new fan, or because of cooling paste replacement (however, temps were good already before the replacement).
Avg temp before: 38
Avg temp after: 31
(this is regular operation with very light usage, I didn't compare heavy-load temps)
