The fan on my Akasa AK 965 Cpu Cooler has died.

This has a clip on mount that takes 80mm fans but the original supplied fan is a 92mm with 80mm mounts.

So I'm looking for a replacement fan, needs pwm as well.

So any recommendations as I'm struggling to find anything?

Here's a thread which shows pics of all the bits, but its old and the fans mentioned don't seem to available now. https://forums.ebuyer.com/showthread...-AK-876-AK-965
