CPU heatsinks

[ksoth]

Man, I bought the thermaltake orb cooler, and just read that it pretty much sucks, since my Duron 700 idles at about 50°-53° with a 30° Chassis temperature in about a 22° room temperature. That's pretty weak. The kick ass Swiftech MC462 sounds good, but that [-peep-] is like $80!!!!!! Now that's just insane. So, I'm gonna make my own. Pretty much just copy how that one is made, only do a few things a bit better. Probably get that made for like $15. But, I'm not sure where to get the aluminum pins. Anyone know? Probably just have to buy like a 3/16" round bar of aluminum and cut it to size, ya? Also, anyone know where to get some clips? I can't just rip the clip off my thermaltake, as the one it has is pretty frickin retarded. Maybe just ghettoize it with some baling wire? HAHAHA. I already made my custom RAMsinks which was pretty fun, so this should be much cooler! (literally!)

Thanks.

You could also use the four holes in the motherboard and four bolts/8 nuts to hold it. Get thin nuts, put the bolts through the back of the board, and screw the thin nuts on to hold them to the board. Then you have a board with four bolts attached, if the nuts are thin enough you can install the heatsink over them and put on four more nuts If you want to keep steady pressure on them, make those last four nylock nuts, and use them to compress springs, where the springs provide the force against the heatsink. By attaching the bolts to the board in this fashion, your heatsink can be installed or removed without removing the motherboard or modifying the case.

Im pretty sure the alum pins in the Swiftech are a press fit. This would require turning the ends of the pins to a specific size and also holding the holes in the copper plate to a specific size (probably by reaming) so as to allow the proper fit for pressing.
Do you have a lathe and a drill press?

I have a drill press, of course... A lathe isn't needed. You get an aluminum stock bar slightly larger (slightly) than the holes you drill into the copper, then tap the aluminum pins in. Aluminum and copper are both fairly soft metals, so they will deform a bit with some tweakage. Or, you know, just make the holes the same size as the pins and use a thermal epoxy or something to glue em in. Man, I called some copper places, and this one place wanted $100 for a 3"x3"x3/8" copper plate!!!!!! That's suck f*cked up stuff there.... So, I'll have to look around some more for a cheaper place, as I think they're trying to screw me. I'll make something that's real sweet...

If you're wanting to use your drill press, a solid block is definately the way to go. Copper will give you noticably better results than aluminium, but you'll have to watch for oxidation all the time. If you can't find a halfway decent metal/contractor shop around where you live, you might give www.metalsdepot.com a look. Probably around $100 for a 1x1x36.
