So, I made an error with the fujipoly extreme, thinking that it was adhesive. However I'll be able to use it in my Blood and Guts build to redo the VRM heatsink on my Crosshair V Formula Z.
It's probably just as well, since it got me thinking about how to better cool the VRMs on my GPUs. I'm planning on this setup for VRM2 and the RAM on my R9 290s, and since they don't make much heat it's no big deal to stick with the thermal tape that came on the ramsinks rather than the fujipoly extreme. Apologies for the crappy shots, these are just mockups of the GPU cooling:
For VRM1, I was planning on this but while researching the fujipoly I realized that it wouldn't provide enough surface area:
So I resolved to use some aluminum to better cool VRM1. I went to a local metals shop and bought a few off-cuts, about $10 worth:
They are 1/4" thick in order to fit on the VRMs, I have a 1/4x1/4, a 1/4x1/2, and a 1/4x1 piece. At first I was thinking of making a tee, with the thermal pad on the bottom and between the base and top of the tee, and the ramsinks adhered to the top. Here is a mockup:
But I'd have to attach the top through the base and the mounting holes in the pcb. I think this would be lighter and more elegant, while requiring one layer of fujipoly instead of two, and radiating more heat. I'll cut a notch at the ends, drill (ahhhhhhhhhh!) through for the mount, and put the ramsinks on the sides of a single 1/4x1 piece, like so:
The cuts shouldn't be difficult, and I can polish the aluminum bar a bit before I install the ramsinks. What do you guys think?
*edit* Actually, I just tried the last mockup with another ramsink sitting right on top. Fits perfectly and hides the edge of the aluminum bar.
