Using PSU to Exhaust warm air from case

post #1 of 10
Thread Starter 
Hey guys,

So my power supply is right underneath one of my MSI GTX 465 GE.
If I flipped over my psu so it would intake the exhaust from my video card and push it out through its back would this be effective in lowering my video cards temp?

Or would this own my psu?

Not sure where I should post this but I reckon this falls under air cooling.

Hot air rises. I don't see how it will be exhausting anything?

Not recommended. PSU has an operating temp of 50C.... Also thermodynamics

You are fine, heat rises so it won't be pulling hot air from the GPU just case temp air.

Put your case on a stand.
Cut a hole directly underneath PSU.
Flip PSU over.
Place fan over fan.
???
Profit.

Hot air only rises when it is stationary or very close to it.

This is a VERY VERY bad idea and can kill your power supply.

I'm sure he has case fans that stirs up the heat.
I'm sure it's not just sitting there stagnant.

If hot air rises regardless of the power supply's fan, then why the hell do we have case fans? Jeez. You could theoretically do that and might even see actual differences in GPU temps, but the extreme likelihood of killing your PSU is just not worth it.

because fans are much better at exhausting air than... uh.... nothing?

Power supply fan is for the power supply,and that is all it should be counted on keeping cool. Feeding the power supply a steady diet of hot air makes a lot of assumptions about the power supply (like it is not better if it also runs cool).
