I just tried the 2206 BIOS and the CPU fan still runs at 100% also there is another problem where you cannot disable the onboard Audio.

So I thought I'd give the 2301 BIOS a go just to see and it seems to be the same as the 2206 but I put the audio into vista mode and then disabled it, so now it seems to be detected as a unknown device.

I'm just using speedfan to get my cpu fan down to 75%-80% so it's not noisy, need to find something similar for linux now tho

I notice the BIOS program only allows updates aswell, I was going to try the 1305 or even 1503 BIOS if I could get it to force a downgrade
