    Less fans = more performance!

    (In my case(pun intended) anyways!) In my case i have a 500watt psu. You WOULD think this would be enough, right? WRONG! Also in my case i have(had) 5 case fans, just for the case, not counting the cpu, or the psu its self. These fans were pulled from a switch(yes all the fans came from the same switch).
    After i installed my GeForce 3, it would crash after about 2min into windows. So the whole time, i was untweaking, underclocking, and everthing else i could think of. I thought it was the card screwing everything up! But NOOOO! Its my psu! I unplugged 2 of the fans and my system finally became stable at 140 fsb. Soooo, i unplugged all but 2 intakes and now im running about 146fsb. Awwwwwwwwwwwwwwwwwwwwww! The feeling of finding the problem and fixing it!!!! Now for my overheating issues. .

    So, this is why the subject reads "Less fans= more peformance"

    You may perhaps make it "Less fans = More stability"

    Hi OC guy
    Well, i think the the PSU you are using is not a high quality one ..
    I have 300watts PSU from AOpen and it can handle really a lot of stuff .. mind you my system is OCed to 150 MHz FSB + voltage is raised for Memory and CPU, in this case my rig need more juice ...

    500Watts seems way too high .. if it can`t handle the GF3, few fans and 146FSB OC .. then, there must be something wrong with the PSU ...

    IMO
    Regards

    Who makes the psu?? Sounds more like 50 watts.. sheesh...

    Is it an enermax??? They have been known to have a low 5v rail... and that is bad for AMD bases systems because they need a solid 5v rail.. if the fans were draining of of the 5v rail that migth explain the less fans= more performance..

    What is a "rail", if you dont mind me asking?? Im pretty sure its a noname brand, and the fans are running of the 12v lines. It makes me mad that i paid the extra bucks for the 500 watter and it blows this bad. God im glad i didnt get the 300watt ver., i would've really been pissed.

    The 5 volt rail is just another term for the circuit.

    A quality 400 watt p/s has specs like this->>

    +3.3v = 28amps
    +5.0v = 40 "
    +12v = 15 "

    Hmmm, very interesting, ill have to read up on this. Maybe a combo of 12 and 5v fan speeds will free up some juice.

    My friend recently bought a cheap case w/300 watt PSU running 1 fan, 2 HDs, CDRW, Floppy, and Zip Drive with a 1.2 Athlon and not even 2 months later the PSU is dead!... kaput.. threw a good 250w PSU and booted up np so I guess I've learnt my lesson about cheap PSUs

    BTW: I thought Enermax were great PSU's for AMD systems.??? are they not AMD approved?

    it's all about quality, not quantity. three well placed fans can do a far better job than five fans for show...

    Screw the noise. I just want a few(yeah right) fans that wont crash my damn pc after 2mins. Thats what my other ones did. So took them out. They just used too much juice.

    You can always get a 3-4" "Boxer" fan, 120vac

    Use a hole saw for a couple of holes on the case at convenient points and power them from the wall socket, not the power supply.

    What were/are those fans you're using?
    And how big are they?
    They must be something pretty potent---or at least powerhungry...
    The baddest 80mm Delta Screamer EHO (extreme high output) fan (80.16CFM @ 5700 RPM) "only" draws alittle over 1 amp---that 500watt p/s must have some serious issues...

    Like storm2k said, quality matters just as much as quantity. I'd like to add a few other things too look for in a quality supply:

    Uses 18 gauge wires (18 AWG), not 20 gauge.
    Weighs 3 lbs or more.
    ball bearing fan
    AMD approval <---- very important

    I have no case fans. Well, none running at least. I have one in the front and back but I saw no temp differences with them on. Just more noise.
    Nope, I refuse to have a signature
