Re: Silent PC build

I guess I wasn't expecting "decent" fanless GPUs to exist. They're surprisingly rare. I'm not really sure why, because $20 or $30 extra is really not that much to shut the thing up, and GPUs are traditionally the loud annoying component of any system. (I guess quiet computing is still kin...

Re: Silent PC build

If you're using "silent" to mean "inaudible over ambient noise" your task isn't all that hard. Nor do you have to limit your component choice all that drastically--you won't be pushing the highest end GPU unless you invest a lot in its cooler, but a midrange discrete GPU is accep...

Re: Crazy idea to cool/silence a computer.

It seems clear to me if you really wanted to submerge your system and still cool it passively. you'd also submerge the bottom half of a large metal heatsync with the top half exposed to air. And you could pretty easily remove the oil from that equation just slapping the heatsync on the processor di...

Re: Crazy idea to cool/silence a computer.

You may be forgetting that the oil is three orders of magnitude denser than air, so not only is it approx. 1000x more efficient volumetrically at storing heat, there's also a significant amount more convective forces acting on it. Coefficients of thermal expansion are significant there (after all, w...

Re: Crazy idea to cool/silence a computer.

You have correctly identified the bottleneck in the system as transferring the heat into the air, but copper doesn't necessarily fix that. What fixes it is airflow--air is a good insulator, and lacks the density to be a good store of heat, so you need to move a lot of it across your hot surface to p...
