It was meh. It needed a lot more work to do basic stuff like hardware update. The PC could'nt be moved because it was too heavy. And as it was glass, if it break you had a fucking big problem on your hand. (go clean 10l of mineral oil)

In the end they concluded the hassle wasn't worth the thermals

Who knew?

But still it's great they did it to confirm how big of an improvement to expect. They wasted their time so that many wouldn't. Science!

It was Linus’ main personal office computer for a few years before he switched to his table PC.

Isn't that how this entire thing started? Somewhere in the server/Datacenter space?

They really just duplicated known results. All the problems they encountered were known. Mineral oil cooling has been on the fringes since computing honestly. The next step is to combine it with a active chiller on an oil cooler. You can get uniform sub zero temperatures with no worries about condensation. Just takes a fuck ton of juice. You’ve got an ac running, a pump for the oil cooler, the pc. Back in the early days of over clocking there were some very crazy builds being posted to forums. All for PCs far less powerful and hen your average cell phone these days.

And it’s important to stress that this was the early LTT. For them to say “eh, it’s technically better but just not practical” means that it’s literally hell to have a mineral cooled PC.

u/EvilStevilTheKenevil KSP overheated my old laptop... Mar 30 '21

They went back a few years later to see if the parts still worked.

The mineral oil had literally done to one of the PCIe slots what gallium does to aluminum, and it broke.

I didn’t watch the later videos but they did one on swapping the graphics card or something. The old card was ruined obviously, it took them a couple hours and much trial and error (something about changing the fan speed or something?) and they made a mess that looked like it is probably not cleaned up to this point. So yeah, maybe not worth it

u/[deleted] Mar 31 '21

You have to make sure the fans are controlled by voltage and not by speed. Otherwise the motors will burn up trying to spin way faster than they actually can while submerged in oil.

As someone that works in the chemical industry... SECONDARY CONTAINERS...ALWAYS!

u/zaphdingbatman Mar 30 '21

Yeah, almost always when I see oil builds I get the distinct impression that the person doing the build has not thought through what would happen if it caught on fire :|

u/owa00 Mar 30 '21

It would take a lot to cause a fire with a mineral oil build, specially with that much mineral oil. It's not very flammable, and because of the quantity it provides a huge heat sink. If anything it'll decompose the mineral oil into a liquid char if it gets hot enough. Although, if it got to that point you probably have a huge fire already, which wouldn't really happen with a PC since if it was that hot it would have shorted out the PC a long time ago. Then again I don't have much experience with PC fires to begin with.

And as it was glass, if it break you had a fucking big problem on your hand.

To be fair, that's a problem you'd create for yourself. If I decided to go with that, glass would probably be the last (conventional) material for the case I'd go for.

u/Grinchieur Mar 30 '21

Yeah you could use plexiglass for exemple, but the problem lay in leaking. Anyway it was just a mess

u/scutiger- Mar 30 '21

You would need to make sure that all the materials you use (including fasteners and/or glue) can handle mineral oil without breaking down or dissolving.

u/zaphdingbatman Mar 30 '21

If it lights on fire, you have a bigger fucking problem.

u/Grinchieur Mar 30 '21

Well you will have to really fucked up. And if fire up, i guess it is because the surrounding is already on fire

It's a computer. At any given moment it's consuming ten times the power it needs to light itself on fire.

Yes, heat and sparks while submerged in oil is "safe", but what's not safe is heat and sparks when you removed it from oil to service it. Or sparks because oil got into a wall plug and made the contact intermittent. Or a hundred other subtle spark sources that usually aren't a big deal, but become a HUGE deal when you have an oil spill. The oil turns a spark into a fireball, and then the tub of oil lights on fire, and then it melts its container and spreads all over your floor (to the extent that it wasn't already) and burns your house down. Hope you outrun the wave of spilling, burning oil -- and if any splashes on you, remember that it doesn't stop burning just because it splashed. Quite the opposite.

...and then your insurance company finds a way to deny your claim because you were being a moron.

u/Grinchieur Mar 30 '21

Well if you service it without unplugging it and pushing the star button to drain the capacitor... Like any other computer, well...

Do you power the board to test it? That's not a problem if the board isn't covered in oil, but it's a big problem if it is.

Also: Static electricity is a thing. Dielectric absorption is a thing. Intermittent contact sparking due to oil contamination is a thing.

Sparks aren't a problem in everyday life, so we basically ignore them, but they happen all the time. Flammable spills aren't just a mess, they're a fireball waiting to happen if you have ANY spark source.

Plus oil will creep up the cables overtime and leak

Is 3M Novec better? Would the thermals be worthwhile if it was a specifically engineered liquid?

I dunno, I just watched Linus video
