Question - Reversing PS Fan, and more!

[Nefir]

Question: how does one go about reversing the direction of a power source fan? I can't seem to find any info on this. Sorry if its a newbie question thats been answered on this board hundreds of times 🙂

Also, is the below an acceptable cooling setup for a 950mhz Thunderbird on an Abit KT7 RAID 100 (possible future overclocking) in a Full Tower?

Front Bottom: 1 dinky fan (came with case, blowing in)
Rear Top: 2 dinky fans (came with case, blowing out)
Power Source: 1 dinky fan (300W, fan possibly reversed thus blowing in)
Lowest 5.25" Bay: CoolerMaster 4002 CoolDrive Hard Drive Cooler (hopefully blowing in)
Processor: Alpha PAL6035MUC Socket-A Heatsink/Fan
The case itself only has ventilation (whatever you call those slits) in the front, back, and one side. Will I have to butcher the case and add ventilation to the other side?

Thanks in advance.

Fix your fan

To reverse the Power SUPPLY fan direction you physically flip the fan over. In other words, you carefully open the unplugged PS, you remove the screws fastening the fan to the PS housing, turn the fan around, re-install the screws (opposite side of the fan from which they were threaded). IMHO, a PS cooling fan should blow OUT.
