    For a KD7A? One of mine's going south, I think.

    They do that, don't they?

    ALL the ABIT NB coolers I have seen are that way...they use cheap sleeve bearings.

    If you aren't interested in getting a new CPU cooler (mine cools the entire MOBO, NB included), then there are some aftermarket solutions available.

    Here's a fanless solution that works as well as the ABIT active HS...

    But here's the cooler my CPU wears...it cost $44, BTW.

    You can see how it would cool the RAM, NB, MOSFETs and all the caps and such, can't you? There isn't much blocking the airflow down through the fins, so the air streams over the MOBO and chills everything out quite well.

    Plus it dropped my CPU temps by about 10 degrees Centigrade...so if the Zalman CNPS7700-Cu (or AlCu) will fit your boad, I highly recommend it.

    Good luck!

    PS. If you get another ABIT fan, it'll do the same thing in a few months.

    How would you know if your NB fan is going out - short of staring at it through a clear window?

    It started making racket, so I opened up the case and looked. It was just barely turning. I took it out and gave it a good soaking in WD-40, which freed it up and it's running fine now, but I don't think it'll last.

    I have never done more than discarded them, but if theres a way to get the fan blades off the spindle, you should be able to get some cup grease in there.

    That'll extend fan life for quite a while...but those things are so incredibly cheap to start with, there's no telling if they'll even work after being disassembled.

    And that cheap aluminum heatsink will NOT cool efficiently enough in passive mode; you'd need to use a passthrough CPU cooler or another NB cooler, that's all there is to it.

    The best cheap fix, besides buttering it up with axle grease, is to jury-rig a 60mm or 80mm fan to blow directly onto that cooler.

    And remember, WD-40 has no real lubricative properties...it's merely refined Kerosene.

    Good luck!

    You might find something on these pages.

    http://www.mouser.com/catalog/621/1273.pdf

    I just found an old P100 or P133 fan to work on my nVidia 4800 vid card. But someone pointed me to the above site. Sure has a hell of a selection.

    Actually, after cleaning it with WD-40 I applied a couple of drops of Militec on the bearings. But your points are well taken.

    Rager and Wash, thanks, I'll look into those. ;)

    You're welcome.

    I have taken the time to take a proc cooler fan apart. It's an Orb brand heatsink and fan. With a magnifying lamp and the right tools it wasn't too bad.

    I lubed it with some synthetic lube and got another 6 months out of it. It was just kinda dry, not particularly worn. I can't remember, I think it was setup with ball bearings not a sleeve.
