Question about PSU and fan speed on boot

#1popping4itPosted 2/15/2014 1:20:48 AM(edited)
whenver i cold boot or come back from standby the power supply fan goes max speed for about a second then goes to normal. I've seen this on other computers as well.

what the heck... is there anyway to prevent this from happening? thanks.

I wouldnt think so... there's no way for a computer to control a PSU... that I know of.

All of my fans do the same thing for a second when I boot my PC. My last rig didn't do this, but this one does.
I actually kinda like it. I figure it helps get rid of loose dust.

Out of curiosity, what app or tool are you using to determine that the PSU is running at max speed? I didn't even know it was possible to keep track of such a thing.

i dont think theres any control i just hear the thing goes VOOOOOOOOM on boot.

im kind of wondering if its the power supply or the motherboard that determines this sort of thing. since the power on switch goes to the motherboard but the psu goes from the wall.

The power supply has its own fan controller and does that. It can't be controlled.
