bolt-thru S478 heatsink?

I ordered this motherboard
without noticing that the cpu heatsink retention bracket was missing.

Looking for heatsink solutions.

Edit: Found this one, but it has a single review, a bad one.

I'm cooling a 2.0Ghz P4 mobile chip, which is the same as the desktop chip except for speedstep support, and it lacks a heatspreader, which means that heatsinks which assume exact clearance for a chip with a heatspreader will not work. Luckily, the standard Intel heatsink WILL work with a mobile P4 chip, but it requires the retention bracket.
 
Perhaps request in For Sale/Trade that you are looking for a replacement socket 478 retention bracket. Someone out there must have a dead board that they can yank one off and mail to you for minimal cost.

As for your mobile chip, good luck on getting the mobile P4 to run on it. Asus boards are usually good for it, but sometimes you may need to bend a pin to make it boot up, and do other tricks to it to run at whatever speed you want. With SpeedStep, the chip will boot with a 12x multiplier on a desktop board, meaning 1.2GHz. That mATX Asus board probably does not have overclocking in the BIOS, so you'll have to pin mod it to a higher FSB. Your choices are 400/533/800 (AKA 100/133/200 in BIOS). Those translate to 1.2GHz, 1.6GHz and 2.4GHz.

This thread might help It is for mobile Celerons, but a lot of that information applies to mobile P4.

As for a bolt-thru P4 heatsink, I have one on my mobile P4. 😀 It's my server box and the heatsink is an Alpha brand. Good luck finding one for sale. 😕
 
Well, the mobile chip boots fine in my 845PE mobo without modifications. That board (which is unfortunately failing) has overclocking features with jumper settings for a 200Mhz FSB setting, so the chip is currently running at 2.4Ghz happily.

The replacement mobo has an 865G chipset, which (hopefully) will likewise run the mobile chip without modifications. Otherwise, I will have to pick up a replacement 2.4-2.8 Northwood P4 S478 CPU too.
 
It isn't the chipset that makes the board work with the mobiles. Asus BIOSes tended to work with them. Regarding Asus mATX boards, BITD they were terrible overclockers like all other mATX boards back then. Only ones that barely OC'd at all were the SiS chipset boards like the P4S8X.
 
I believe the Raidmax Glacier fits socket 478 and is bolt through, might want to try one of those. I have one sitting on my shelf waiting to be installed in a system lol. Pretty big.....
