so why does it work with the liquid in it?

 

 

kinda dumb...it would be nicer if it incorporated the CD drive INTO the tank, and if the tank were seperated into a running liquid free computer, and an actual aquarium

because mineral oil doesn't conduct electricity.

nothing new, I built one 7 years ago.

mine was self enclosed, and had a seperate chamber for the drives.

Mine also had a heat exchanger and pump to circulate the mineral oil.

 

it allowed me to run a duron 600 at 1100 MHz, stable.

that was faster than anything you could buy from AMD at the time.

hmm....i bet working on one is kinda slimy

honestly the submersion process is cool, but it's not the best way to cool. Mineral oil just isn't a very good conductor of heat.

I eventually went to a custom copper waterjacket I built, so I could focus te cooling directly to the CPU die.

that let me hit 1200 MHz stable with a 600 Mhz chip.

that and the then brand new Geforce 2 GTS I had were pretty impressive.

Whats the benefit.... I know I am going to get flamed for that question ;) I thought your computer was supposed to be used for surfing porn and posting on the forums

[JeepcoMJ]

not to mention that mineral oil has GOT to be flammable...me no likey the idea of lighting my desk/house/computer on fire

oil is a lube so I imagine your internet experience would be better?

Now that's funny right there!!

well, my day job is computers. At the time I was young, had too much money and liked to play video games.

It was also a challenge.

engineering a water cooling system to dissipate the kind of thermal energy I was developing was pretty cool.

I'm going to type some stuff now, your eyes will likely roll into your skull.

 

A duron 600 thunderbird core dissipates about 80W of heat from a die smaller than a dime.

After I upped the core voltage and the clock speed I figured mine was putting out about 170W of heat.

In order to keep the transistors stable at that kind of core voltage you have to keep it running real cool. the chips were specced to run at 85* C, but that was the top of the thermal limits.

Mine ran nominally at about 55C. but this was after quite a bit of engineering, and a 300 GPH pump feeding into a large heatercore.

The thermal load was sufficient to heat my room.

 

Just think of it like rockcrawling for nerds, there's no NEED for you to truggy a perfectly good MJ, you just got there because it was an end to a means.

thermal load...core voltage.....

blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah

 

nominal value...clock speed (WTF is THAT???)

all that, and you forget to put 80/90W in a new differential????

 

:D

 

(sorry, had to bust yer stones a bit there :jump: )

man, I finished swapping that axle in at 11 PM, and didn't feel like waiting for the RTV to dry. Should have left a note on my steering wheel.

 

but that about sums me up, it's always a simple thing forget

[Twisty]

I think thats pretty cool.. I have a watercooling system for my desktop. Its a pretty crappy "kit" that I bought that does not have very wide tubing..but I have CPU and GPU coolers, and the temps stay rather low. I like it

 

Now I have to try the mineral oil thing with my spare P4 and motherboard.

 

Question.........do you put the hard drive in the mineral oil too, or just the motherboard, and cards?

Ok so let me get this straight... you put a Clock in your computer :???: Then you heated your room with the heat off of it :dunno: I guess tis is why I never made it as a nerd :roll:

nothing mechanical.

the fluid would ruin the HDD. THe HDD arm rides on a thin cushion of air between the read/write head and the platters.

OK, let me try and explain the basics of a CPU in one hundred words or less.

 

A CPU is made up of millions of transistors, they're basically microscopic on/off switches. On=1 Off=0 This is how a CPU does work, by switching them on and off rapidly. A CPU running at 600 MHz does this 600 times a second. By increasing the clock speed you increase how many ops you can do a second, thereby increasing the speed of your calculations.

Unfortunately everytime one of those transistors switches state it generates heat, and consumes electricity. So, in oder to run a processor at a faster than designed speed you must increase the core voltage, so that the transistors remain stable. Increasing the core voltage increase the amount of heat you must dissipate. As does increasing the core's clock speed. So when you increase the voltage AND the speed you end up with something the size of a dime producing enough heat to heat a room.

water cooling and submersion cooling are more effective at removing that heat form the core than air to air heatsinks.

 

Think of it like a diesel.

You want to have more power, so you up the boost. When you up the boost you also must add more fuel, both of those make your EGT's go up.

isn't that what's referred to as "overclocking" or something like that?

yes.
