    Can anyone tell me specifics on these fans? I need four new ones as they are failing. I can't seem to find information on these. I have not removed them yet but it does not look like they have a square mounting configuration like most fans. What is the voltage?
    Thanks for any help.

    Yes, there are very few of us, we tend to lurk in the shadows waiting for an FX-57 to drop out of the sky.... ;-> :-) Reply

    that mobo looks like something from my nightmares. here i am trying to reduce fans and use bigger ones with fanbuses to reduce noise and this thing comes with 4 tiny ones. wouldn't all those fans be useless if your case do not move air well? just blow around the hot air inside the case. Reply

    The noise level is okay, not as good as a fanless setup but so far not too bad. I will be conducting thermal tests with only the power supply running and a stock Intel heatsink/fan from a 820D to see how well the rear two fans exit air. Reply

    More like how much dog hair will the fans collect over the next week. ;-) Reply

    - We will be comparing the thermal characteristics of this system to Asus's 8-phase power and fanless cooper heat pipe technology in the near future -

    Hi (as I'm new around here)...and a question. That Asus board is also 975x? :) cuz I'm rather keen on something less noisy then 4 60mm plastic fans. If I'd like a vacuum cleaner in a comp, I'd still stick to FX 5800 :). I'm really thinking of coming back to Intel, especially when Presler appears, but I don't want too much noise

    And 2nd question. Is it possible to have two x1800Xl on crossfire, and also squeeze the X-fi card on that board (I pressume that other 975x boards will have same PCI-PCI-ex design?)
