Y-ellow Y'all.
	I know I'm prolonging this perhaps beyond it's use-by date but now I'm
really curious.

How 'n' hell do Frost-free/no-frost and auto-defrost fridges work? I don't
actually have one so I don't know but they have these little vent things
all over the place. Could some scheme like this be adapted?

I was thinking last night, perhaps if you were real careful, you could
actually remove the pump and heat exchangers from a fridge and then build
them into something like a printer hood? After all, this is all a cryo-CPU
cooler is. A very small fridge. My guess is though that the CPU cryos
probably make a high pitched wining sound due to their small size.

But if you wanted to go all the way you could take a leaf out of IBM's book
and do what they did on the 3090s. Where they had liquid nitrogen pumped
through these little spring loaded booties on top of every chip.

Doing the Seamore Cray thing and dumping your entire machine in something
Like Flurinert (as Eric Suggested) would be the way to go. But it's so damn
expensive. You wouldn't want to spill a drop. And you probably wouldn't
want to immerse your HDs in it either.

If hard drives still work like they use to, the chambers aren't
hermetically sealed. There is an air filter on them that filters out
particles larger than about a micron. The heads themselves float on a
cushion of air, a couple of microns above the disk surface. Imagine trying
to run that in a bath of flurinert. So you're back to square one.

But probably the best way to get round the problem is to simply build
yourself some kind  of vocal booth. A room isolated from your control
room/studio where you can plonk people who want to sing or play acoustic
instruments. I just wish I had room to do that. The fan noise I can
actually live with personally.

Be absolutely Icebox.
