Sweet sooo any idea where to get a single 18 volt battery or 3 6 volt batteries? 6-10ah.
size.. probably about 6x6x6 cube.

That article is a good read, but fails to mention AMD's complete failure in relative thermal performance in the 2000's. Intel's processors had significantly lower TDP for the same performance levels, and at least for me, that was a major factor, as I don't the sound of massive airflow solutions. I've been watercooled since 2004, but even so, going with Intel at the time left me with a solution where the CPU ran at <100F and the fan barely spun. For other people the higher thermal overhead allowed for easier overclocking of Intel processors.

Oh man, early 2000's water cooling was legit. I built my first water cooled rig on a PIII 450 Slot 1 CPU plugged into an ABit BX6 R2 motherboard. Cooler was built from a peltier cooler harvested from some random piece of industrial equipment I bought off eBay, a spare heater core from my 66 Mustang and a fish tank circulation pump all running on a spare AT power supply. I managed to push that thing somewhere past 750MHz, **** was dope.

System died when the ice that condensed on the edge of the peltier block melted when the system was powered off, and it dripped into the CPU slot. Much sadness.

I am debating on throwing my next build in mineral oil.

I'm surprised that the fans spin in the oil, that's kinda cool. Are there any issues with the oil? Like, dust or water contamination?

Just keeping it closed with an average seal is good enough. According to people have done it the main issue is that the mineral oil makes the wire shielding stiff and susceptible to cracking. Its essential that the motherboard has all the plugs facing up so most of the cables are out of the way. As far as replacing the mineral oil goes the dude that ran it for 5 years says every 2 years or so.

I imagine it's also a hell of a mess to clean up when you decide it's time to upgrade the ram.

Firestone scams customers...

I'm not often a fan of the CA B.A.R., but good on them for this. I rather dislike dishonest repair shops ��

Firestone has always done alright by me. Goodyear on the other hand, is a bunch of shady bastards. It all depends on where you go, and who is running the shop.

I get my alignments done at a local Firestone. Mostly because the tech who does it is a friend and will hit the numbers I want dead on without any questions asked. I also have the lifetime alignments through them so I sort of take all my miata's there and get them done under the that.

Yeah, when I took my Miata in, I asked for "custom" specs (FM numbers), which they hit right on the money. Even took me out in the shop to confirm that's what I wanted before they took it off the lift. Like I said, it's all dependent on the shop manager. A good manager keeps customers happy and coming back. A guy that tries to milk the customers soon loses business.

That said, it's their job to upsell if they can. Need new pads? Try to get them to spring for rotors at the same time. It's (unfortunately) the way the corporate offices expect them to run the place. I've never had a problem just telling them no.

Nope, just pull up the board and pop the ram in. It might be a 2 person job though since you'll need 1 to hold the system over the oil while you swap the ram. Main problem is that its impossible to wash the components if you decide to go back to a normal case.

For firestone my buddy got scammed for brake rotors, brake fluid flush and tranny flush.

Meh, I bet QD Electrical Parts Cleaner would work fairly well.



I used it to clean Pepsi off a motherboard after I made a friend do an involuntary spit-take. System ran just fine after that

I am no longer impressed by people immersing their computers in mineral oil.

Serious question: why not use water? It's less viscous, has a higher thermal conductivity, and is much easier to work with. Not seawater obviously, but I'd think that distilled water from the grocery store would suffice.

I should bring a sample of store-bought distilled water with me the next time I go up to Empire to do the analysis on the chilled-water system for the transmitter. We have a tool that measures the conductivity of water down into the μS/m region.

I'd be worried about it still becoming conductive and corrosion.

Water cooled applications are where it's at

Because distilled water will become conductive in about an hour of running just from contaminants on the surface of the motherboard/tank/and radiator.

I don't see the point in a lot of **** that g4m3r d00dz do, and haven't for many years.

Like buying shitty CPUs, immersing them in liquid helium, and powering them directly with the output of Niagara Falls, rather than just buying a decent-quality processor in the first place.

Or all this case-modding **** with the flashy lights and the polycarb. See-thru PC cases are so 1965...

Good point.

So use perfluorotripentylamine, then. Or 2-butyl-tetrahydrofurane. Just something that isn't friggin' oil... It's lazy.

This is all people who pour baby oil onto their motherboard:
