Default Re: Testing under vacuum

Hey thanks guys, this is good stuff. It's starting to look like the mobo would just fry.

In this test, I'd probably run a full CPU load test, so there would be a significant amount of heat there. If I only ran a low power test, we're still talking about a lot of power.


Following your suggestion (get77), I gave some thought to an immersed test run, but I can't imagine what fluid would be both dielectric, and a low thermal conductor, for a reasonable price.

It finally just hit me; I started this idea with a target vacuum of 1 millibar; what if I progressively lowered the pressure, starting from atmosphere, take some temp measurements around the mobo's surface, and see what happens as I drop the vacuum in 100 millibar (10% of atm) increments?

I've got some mylar sheeting that I could use to isolate various components from radiation heating.
