Computer CPU Memory

Cpu Fan doesent fit on Micro-BTX motherboard, Why?

I recently bought a lga 775 socket cpu fan for my pentium d cpu on an intel D945GCz microbtx motherboard. But when i took out the previous heatsink of my cpu i noticed that the holes were way to far apart to fit my new cpu fan. And there werent any other holes or openings for my fan either. Now i know that i got the socket type and everything right, but so now, is it possibly that microbtx have different fan sockets than atx and microatx. If so (which is what i think, comparing pictures of microbtx and atx motherboards), does anyone know where i can buy a microbtx fan?
thanx
no the motherboard is a d945 but the socket is still 775, and no screws are too far aport for my new one.

Well, even if they both had the same socket type; it doesn’t mean that the CPU will work, or the fan, or the powersupply etc. etc.

I mean, for example; you get a Shuttle PC (those cubic ones) even though they may have the same CPU socket number, you may not be able to use the high end CPU (of that socket) Because the CPU will overheat, the motherboard is not compatible with Dual-Core etc.

Anyways, I’ve got a 120mm CPU fan that only goes on specific model of heatsinks. You’d think 120mm is a 120mm and should work with any heatsinks of that size but nope… And not to mention when I had liquid glycol cooling in there… I removed the liquid/water cooling and tried to attach a regular/air cooling socket fan… well, the OEM guys had removed the original CPU heatsink mount from the motherboard (little plastic and some screws that you won’t find in stores unless you buy the motherboard)

If it doesn’t fit without you modding the screw holes etc. don’t use it… trust me on this… just go out and spend $30~, and get the one that fits… Do you know what happens when your CPU fan falls off of the heatsink when the PC is ON? A damaged CPU is the least of your worries…

Again, if it doesn’t look like it will fit (screw holes are further part) DO NOT use it. I have had a $8000 loss when my heatsink fell off. (No fan since it was water cooling.) First the CPU got cooked, then the pipes started to melt/expand, then it sprayed water/liquid glycol non-conductive luckly but spilled slimy liquid all over the components then the fallen CPU heatsink destroyed my RAID card (I was running RAID-0) on top of that broke the SATA pin on one of two hard drives which rendered the entire RAID array useless, so there is no way to recover the data on those drives, and only thing that still worked was the RAM and the optical drives. Everything else was DEAD… All because somebody didn’t tightened the screws hard enough.

Don’t bother trying to mod that fan on it, if the fan fell off while you were a sleep (or while I was on vacation in my case… It was dumb of me…) Remember that the fan will still be spinning which can shread the chips on your Motherboard in pieces and your CPU will start to overheat (most modern processors will shutdown but some won’t…) BUY NEW FANS.
