[ale] Replacing Fan in Power Supply?

[Jeff Hubbs]

Jeff -

One thing I would suggest you look into is the temperature of the air 
going into the power supply from inside the case.  If the CPU, RAM, 
video, disk, and chipset are already pre-warming that air significantly, 
then, yeah, your power supply could be running a little hot.  The 
question to ask yourself is this:  is the power supply the principal 
means of exhausting air from the case?

On the machine I'm typing on right now, I have two "pusher" fans in the 
front and two open holes in the rear, below the "puller" fan of the PS. 
    The exiting PS air is warmer than the air that I can barely feel 
coming from the open holes, but consider that the two front fans are 
blowing in roughly twice as much air as the PS is blowing out, so 
there's plenty of air available.  I have filters over my fan inlets to 
keep dust and critters down.

Barring general airflow improvement, you might want to rig up a duct 
inside your case that pulls PS air in from the outside.  However, don't 
position the intake such that it pulls in hot air from another outlet - 
I was screwing around with case fans once and ran into that problem.
