Home made RAM heat-sink

My Kingston HyperX DDR2-1066 modules were getting purdy hot, as high as 65C - so I decided to cool 'em down a bit. After attaching a lil heat-sink, these dropped down to the 30-32C-ish range with exhaust air from the CPU fan.

The first fin was sheared by hand, but it looked crummy, so I fired up my mill to rip out a couple more. I wound up using the hand-sheared fin anyway, but I could replace it in 5 minutes if it turns out I should.










Hand-job :(

Good job! I wish I had a mill, I want to make some heat sinks for my GPU VRMs...

With the surface area equivalent to an entire sheet of plywood, I bet they'd run at ambient. :)  Nice DIY work!

Thanks guys; I have some .050" copper I was gonna use, but, aluminum happened to do the trick.

Fins: AL6061, 5.0" x 3.0" x .050", .25" width with a 1.75" x .0625" gap (1/16" endmill); Drill 5plcs, Y=1.000" X=.500", 4ea+1.000"
Spacer: Al6061, .250" plate 5"long, drilled .125" 5plcs (same spacing); cut at .270" wide.


Since the DIMM-slot spacing is equidistant, these can be stacked to fit more than just the two chips I used (depending on the DIMM heat-spreader, which is .270" to .290".)
