    Yes it can, there are heatsinks inside a PSU for a reason. Since the PSU is basically a transformer, heat is generated when mains current (115V) is converted to 12V DC.

    if your gona put it in a nicer system i wouldnt recommend it cause a power supply can take alot of heat no problem, the only reason why a fan is on a power supply is to keep the small amout of heat it generates out of the case. hope my advice helps, it wouldnt matter if you had it in an older system obviously.

    Its also to provide airflow for even minimally configured systems. For example, in Gateway systems, it is THE ONLY standard fan. They duct the powersupply air over large heatsinks to cool the processor.

    Remember to make that when you replace your PSU fan, you have it blowing outwards.

    Ok, I did everything as normal and now I'm pissed
    I hooked up all my fans to the seconds PSU and then I turned it on
    so the normal SPU was running my mobo and components, 2 HDD's 2 CD-roms and 1 fan
    while the second PSU was running about 5-6 fans.
    I booted up and it said something about a boot error please insert book disk and press enter.
    I did that and WOW, my primary HDD was GONE!!
    I had to re-partition/ format it

    and now I'm in fear if I fried it

    oh well, I guess this is an excuse to get that 7200 Rpm I've always wanted
