Sorry, thought I'd put that. Motherboard is ASRock H81M-DGS R2.0 The BIOS has a whole load of fan customisation available but the fan always runs at the same speed.
I've tried fancontrol. When I run the pwmconfig none of the fans change speed so it says they aren't able to be controlled.
@Velocio I'm mixing terminologies a little. The CPU has one of these http://www.nofancomputer.com/eng/products/CR-80EH.php
as it's passive the air in the case heats up under load which is what I want to turn a fan on to clear.
The temperature I'm measuring is from the CPU/motherboard.
The case fan is actually plugged into the CPU fan jumper, although I've also tried it on the chassis fan jumper. I was assuming that they were sensor bound as there are BIOS settings for fan speed but they don't seem to do anything.
I can find very little info on safe CPU temps. If 85C is OK for two or three hours (and rarely that) then the option is just to leave the passive cooling. It idles around 35C or so so there's no issue there.
Cheers
