.... I wish a company made a copper option with heatpipes, could make a huge difference for overclocking.
Should not be that hard to fabricate on your own .... just need to find out what thickness of the copper slab to get, slice some slots / channels in it and then split a few copper tubes to for the fins that are slid into the slots. All you are left to do is drilling tapped holes for attaching the PCB. I wonder how cost efficient it would be though for just a handful of units ..... ?
digging up an old post here.....anyone think copper foil/tape would transfer heat to the heat-sink more efficiently? just trying to think of inexpensive ways to cool these S5's down. a 6 yard roll of copper foil is 20$ on amazon....could put a later of it on the aluminum heat sink then put on some good thermal compound. just brainstorming here.
My goal is to have much lower temps with a less noisy fan. trying to make this more "home miner" friendly so I can take these out of my garage.
I do not think with it being summer in most places foil will do enough. If you want additional cooling you can add another fan to back. It might make the noise level higher.
Depending on conditions there are not cheap but you could do a push/pull combo of Corsair SP120. I would not recommend this in very hot summer areas I would suggest keeping the higher RPM fan.
