hi all new to the forums and was just after some advice.Iv`e recentely noticed one of the fans on my AMD HD7900 device id 679A is not working but has a quick spin on start up,
the question is are both fans always on or does the secondary fan kick in when a required temp. is reached.
thanks in advance for replies.
I have got the same thing happening on my Radeon HD 7870.
It isn't physically blocked, It is clean etc.
I can make it run via MSI afterburner if I set it to 85% fan speed.
So is it a feature that it only works when it gets hot and if so is there a way to make it spin at normal speed with the other fan.
