    380 -450cfm Delta power MCX4000

    I had ordered this stuff a while ago and they arrived today from sidewindercomputers.com Each 120x38mm Delta 190cfm fan consumes 36W of power You can blow dry your hair with these

    All pics at http://www.fileshosts.com/heatsinks/MCX4000/

    Zalman fan bracket screws and bolts are soooo useful







    Last 2 pics show a 92x25mm Sunon 50cfm fan attached which would hover over the memory slots to cool the memory

    That's a nice idea there with the extra fan bolted on for the RAM, I might give that a try myself.
    I've heard it all, I've seen it all, I've done it all. I just don't remember any of it.

    You need to move upto toriodal fans (rat cages) to get better air pressure and cfm really though, my fans are 24watts and 380cfm... And i use 2 of them... Theyre also considerably quieter than axial fans too.

    toridal fans ?

    lol Liquide



    Just got it up and running and wow!

    high speed = 100% ~4050 rpm/cfm = 190cfm
    medium speed = 75% ~3150 rpm/cfm = 142.5cfm
    low speed = 50% ~2150 rpm/cfm = 95cfm

    on lowest speed setting these 190cfm are as quiet as a mouse but still generate enough air to keep the cpu at idle 0.5 - 1.0C above motherboard temps

    low speed setting
    cpu idle: 24.5 - 25C
    mb idle: 24 - 25C

    Now this is crazy! With this 190cfm delta fan, I'm memtesting passing this 2.4C costa rica @ 285fsb at 1.725v in bios This is the same cpu which before couldn't even pass memtest test #1-3 on first pass @ 276fsb at 1.6-1.825v in bios

    running pcmark2002 @ 285fsb right now.. a whole 15fsb better oc!

    oh i see hehe


    well 2.4C @ 285fsb @ 1.725v managed to run pcmark2002 to the end but rebooted straight after





    2.4C @ 283fsb @ 1.75v ran pcmark2002 fine







    Remember this is with a 2.4C costa which prior to using 190cfm delta couldn't even boot into windows past 278fsb or even run pcmark2002 past 276fsb at any voltages!

    i have to say 190cfm delta fans are awesome probably close to what you'd get with water ???

    2.4C SL6WF Costa rica cpu

    MCX4000 + 92x38mm Sunon 120cfm fan
    max 99.9% stable oc = 270fsb at 1.75-1.8v
    max unstable benchable oc = 270-275fsb
    max boot into windows = 275fsb

    MCX4000 + 120x38mm Delta 190cfm fan
    max 99.9% stable oc = 275-280fsb at 1.70-1.775v
    max unstable benchable oc = 283-284fsb
    max boot into windows = 288fsb

    2.4C Costa Rica 288fsb 3:2 divider
