So the garage pc was a little noisy so I decided to take a look to see why and try to reduce the noise a little. I was hoping to be able to use the stock cooler from my newer AMD chip which has previously been upgraded (Link). Case open and here it is, its a very old athlon pc but it runs the latest version of xubuntu fine. The CPU cooler looks clogged with dust.
See server build post here, as I thought I had encountered hardware issues, I swapped out the stock cooler with something a bit better. The Arctic Alpine 64GT rev.2 is a cheap (less than £10) upgrade and the larger fan should in theory be a little quieter and the bigger heatsink so be more efficient.
Here is the motherboard with stock cooler
The new Cooler
Cooler much bigger than the original
To fit, I just removed the old one, cleaned the CPU with isopropyl alcohol to remove the old thermal paste and clipped the cooler in. It arrived pre-applied with thermal paste.

Job done, seems quieter and a temps are better.
