Question about Power Supply and cooling

[CHHASmatroxuser]

I've just reversed the fan in my PSU as it was blowing into the case, and I wanted it to draw hot air out, as I have installed a 80mm fan in the bottom of the case drawing cool air in.

Do I risk overheating my PSU ?

And should I block the holes in my case making it (almost) airtight except for the fans ?

Many people reverse the PS fan. I would not do so. If your computer starts crashing all the time, you'll know that there is a problem. As for covering holes, why? Just put the fans where you want them, close the case and use the computer.

I've done just what you're thinking of doing and I haven't had any problems. Last year I've reversed the ATX P/S fan so it would exhaust out and (duct) taped other small (non purposely vented) holes. But ideally you want to have as much air going in as those that are exhausting so you have to take that into account as well.

Ok, thanks

I'll be picking up more fans next week, to try and get the system even cooler.

Just after a cold boot the case temp is 26 C, now it has climbed to 37 C, and it looks stabilized. This seems a bit high ?

I have a Katmai 500@560, 2 Maxtor Harddrives, Matrox G400 (I'll bet noone expected that), SBLive, NIC, a DVD drive and a CDRW. The case is an Aopen HX45.

You WANT your PS fan to be blowing OUT of the case. If you make it blow in, the air that you are blowing in will heat up because of the power supply and then you'll be venting warm/hot air into your case.

37 is way hot
over 100 degrees, your goal should be a few degreees over room temp
