    PSU - COOLER MASTER eXtreme RP-500-PCAR 500W

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817171018

    Based on the sticker it seems like manufactured by Seventeam (E141400)

    Based on the TPU (Pancho's) PSU guide Seventeam is supposed to be a good OEM manufacturer of PSUs.

    Now here is the problem -

    Bought this PSU like 1.5 yrs ago. Working great till now. But the Fan is like a Jumbo Jet when the PSU is under load and like a V8 engine when not. It was on the guest computer so to annoy them is perfect:D

    Now I am rebuilding my home server and need to replace the 350w Ultra (ultra quiet one) with more watts. The server is going to run a Phenom 9500 (earlier it was running BE2400 45w cpu), i need more cores for my project.

    So I thought if I make the PSU quiet, it will hold me for a while. So got brave and opened up the PSU grill to reach the fan inside and unplugged it. Replaced with a high cfm quiet Xigmatek 120mm fan. The fan that came out is 2 pin and the new one is 3 pin, i managed to connect the right pins and the fan is super quiet, but it spins with low rpm.

    So when the PSU is powered on and the phenom sucks juice to start, the air that comes out of the PSU is not really warm, but that warm hardware smell is there. When I put the Phenom under load, the fan seems to increase rpm and i can feel the air coming, this time bit warmer and more warm hardware smell. I don't remember smelling this before replacing the fan and when in use 6 months ago.

    So did I mess something up? Is the PSU going to die? Should I just put in a better PSU? Or is this normal for those CM PSUs.

    I have a brand new Antec Trio 430W that needs to go to a customer, should I put that in?

    Also is this Corsair 400W a good one?

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139008

    My system absolute load will not be more than 300W (used with Kill-A-Watt).

    Just need it to be Quiet, Stable and long running.

    Specs:
    Abit mobo powering Phenom 9500 @2.6Ghz, 1.27V
    8GB DDR2 800 Ram
    1 IDE drive for OS
    2 SATA for storage and Virtuals
    1 PCI-E X600SE Video card
    1 Samsung DVDRW
    1 AeroCool Coolwatch fan controlling and temp monitoring guage.
    1 PCI Gig Nic Card
    1 PCI SATA card
    1 Coolermaster 120mm Rear Blue LED fan
    1 Coolermaster 120mm Front regular fan
    All in Coolermaster Elite 335 case with loads of airflow.

    Can someone help me on this. Sorry for the long explanation.

    Thanks,

    :toast:

    I currently use a CM 550W PSU, It's from the same line as yours and you're correct, was maded from SevenTeam.

    I don't need to change the fan, for me It runs quitely and well, If I stress the system It start to make it loud but still not too much, AND I can feel the air blow from it kinda hard (idle and more at load, on both the air is warm/normal) so the fan does It's duty very nice.

    You shouldn't messed with the fan, I think the stock one came tunned to run at determinated speed under certain load, when you changed it maybe the new fan don't run at the required speed, so the PSU heats up more.

    Better to reverse that fan mod. I did a fan mode a years ago, changed the fan of a generic PSU ('cause it was very loudly, doesn't have speed control, so the fan ran at 100% everytime) for a Thunderblade of TT, the PSU died a month later 'cause It heated up a LOT more, even at IDLE the air were much hotter.

    Hope I've been clear, my english isn't so good, I'm from Mexico.

    Thanks for your input, I think I am going to use the Antec instead.

    BTW, your english is really good, not joking.
