I have recently purchased a Intel D945Paw motherboard. I purchased a heatsink and CPU as well. The CPU works, but to my horror there is no way to attach the heatsink to the CPU, since the motherboard lacks the attachment holes (or the ones on there arn't in the currect position). The heatsink I bough said it was Socket 775 compatible, but isn't. Now I need to find a heatsink (cheap one is preferred) for my Socket LGA 755 CPU (3.2Ghz, 800Mhz FSB). I don't want to buy another, wait 3 days for it to arrive only for it to be a complete waist of money if it doesn't mount. The motherboard uses the mBTX formfactor, so finding a comapatible case for it was a pain in the a**. Now the only thing I need is the heatsink. (and fan) Here is a photo of my motherboard that may help determine the currect heatsink attachment: http://img406.imageshack.us/img406/... I have already wasted $19 on the case since it is mATX/ATX and not mBTX. I have found a mBTX case on ebay (and hopefully the mATX one that I bid on will be outbid, since I just now figured out it won't work either, so it may be another $50 down the drain) I don't want to get another motherboard since I can't refund it and already found compatible RAM and CPU (which is now installed) Plus it was cheap considering it had a PCI 16x slot. I tried to find another, but they only had AGP and were more expensive.

Thanks for the link! I found one on the site you listed: http://www.svc.com/acalp7.html Just to make sure, will this mount properly? Could you recommend a better one then what I found?

The Intel site has a HUGE pic of your board & it clearly shows 4 mounting holes for the heatsink: http://support.intel.com/design/mot... Here's the info about the HSF you chose: http://www.arctic-cooling.com/cpu2.... http://www.arctic-cooling.com/downl...

Thanks for the info. Looks to have the same Fan size as the failed heatsink I bought earlier, if this one breaks or is too loud I could try the other. Here is another I found: http://www.geeks.com/details.asp?in... This is from the same site I got everything else and accurding to the description, it is "LGA-775 Prescott" Which is the type of mounting I need right? Right now looking at the other I found, the mounting bracket it uses seems close in size to the one I already have so it looks like it may not fit. I need to know the measurments from attachment hole to attachment hole, and the measurments of the heatsink I'm going to buy since photos alone arn't enough. Here is the link to the heatsink that I bought that turned out not to fit: http://www.geeks.com/details.asp?in... Looks like it has slightly different packaging then what I got. I need to be sure it will fit the motherboard before I spend any more money on one.

Looks like I may need to make a new thread, as it turns out, the BTX formfactor that this motherboard uses make it incompatible with standard LGA 775 (and Prescott ones too) heatsinks. I have found more info on the case and BTX info, and it looks like it needs a special heatsink type called a "Type II BTX Thermal Module". I will have to make a new thread on this since this is a whole new problem.

Just in case one of your threads get's deleted: You might wanna reconsider this idea altogether. Cut your losses...sell the BTX board & go with an ATX or mATX system
