Quote:Anyone have any answers to as what it is? I've watched my CPU & GPU fan speeds as its happening and they do not change at all during this noise.

My GPU fan sometimes does this thing where it chops the fan speed when it's temperature is steady at the limit of the preprogrammed "overheat" value (which is around 70deg on mine I think).

In AMD Catalyst it doesn't recognize the change in fan speed though since it happens so quickly.

Yeah I highly doubt my temps are high at boot after a very cold morning today in the UK. Also I've never had any problems with heat on my CPU or GPU ever. (inb4 something happens now)

But she's all cleaned out now and tightened up. The fans sound a lot quieter, most likely to all the fans being cleaned they were full of dust. (Must remember to buy dust filters)

I'll update this thread if I hear the noise again. Also if anyone's had similar problems like this and think they know what it is feel free to post.
