PSU noise.

post #1 of 2
Thread Starter 
Does a PSU fan spin dynamically? I mean when i see the GPU temps go up - i can also hear the overall PC sound increasing but i've locked the GPU fans at 42% (through AFterburner) at those temps so the sound shouldn't be from the graphic card.....does the PSU & CPU fans adjust according to the temps? If yes, then that explains the noise i'm getting when it's hot. And when i get out of the game and the GPU cools down i can hear the fan noises winding down......

I've put my ears next to the PSU and graphic card....can't tell which is louder....they are too close too each other.

The CPU and the PSU fans are thermal-regulated, so when the load increases the fans should spin up. The CPU fan can be fixed in the sense that you can set it to maximum speed in the motherboard BIOS and then use a fan controller (like a Zalman fanmate) to set it at a fixed, but sufficient speed as usually a huge ramp in fan speed isn't necessary.
