Oil cooling overclocking?

[jointjene]

hey everyone
i ahve heard of an oil which does not conduct electricity.
So i was thinkin, i have an old computer at home pentium 3 933mhz with 768mb ram, that i should sink the mobo with components in the oil and oc it, well since you can put the oil into a freezer and so you can keep it cool.
does anyone think this would work?
20L of oil should be enough. 20L costs about US$100.
Anyone think its worth a try?

people have done it before but this isn't really a long term solution though and there are many problems going with it and lets just name a few here.

Oil is a much thicker liquid than water, what do you plan on using to keep the oil circulating in the system. Your components will heat the oil around it up, without any circulation that oil around the components would not move away (it's a little like watercooling without a pump in the loop or air cooing without a fan although the consequence is less severe).

You said you plan to cool the oil in a freezer. Did you mean you cool the oil before hand and take it out just for a quick run (probably a benchmark) before it warms up or is planning to cool it continuously? A short run might work but you will need an extremely powerful freezer to keep up with the heat load if you plan to cool it continuously.

I have also head that sometimes the oil would slowly damage the capacitor or plastic components on the board killing it eventually.

And why would you want to do this on such a computer? Just wondering, coz with a bigger heatsink for the CPU and video card you may be able to keep it totally fanless.

No, it is a stupid way to waste time, money and pc parts, even if they are old junk pc parts.

hey yeah you guys have all good arguments but the thing is my dad works with the oil and i can get it for free. i was thinkin of just cooling the oil to very low temperatures and then using it to benchmark. also i have a spare freezer here to 2 cool it with. (i have alot of junk flying around). also my dad uses the oil to keep things cool aswell, because he makes metal tools which they cut with high amp electricity, so they use this special cooling oil. thats where i got the idea from. but thx 4 the replies

Have fun. But a freezer isnt powerful enough to cool the heat a pc computer puts out, which is gona stress your freezer and cause condensation all over the freezer most likely will crap out on you.

But ya have at it if you wanna cool the oil and submerge it, the more oil the better, more oil = more room for heat to go through.

But i have a question. If you were to do this would you install a heatsink on the processor without a fan or would you let the oil make bare contact with the processor core?

[jointjene]

haha good question. i havent thoguht of that yet. only the basics. i dont know if it will attack the plastic, or if i shall use the heatsink or not. i think ill get 2 that when im ready. (hopefully soon)
also all u guys have alot of computer sense u shud all go work for a computer company (if you arent already)

[Taichan]

doesn't need to be cooled. there enough surface area to keep the heat out of it. just sink some fans into it and keep it moving

its been done a lot.. just never with a top end hardware...

oil is actually less harmful then air as long as its pure...

don't put you harddrives in it...

I think i saw an article in maximum pc where someone, a beleive a college class, sealed the case and ran on oil and the system ran just fine. here's one from Tom's hardware. http://www.tomshardware.com/2006/01/..._out_the_fans/

Also, a case full of oil would be a much better cooler system than even a water set-up. The oil wouldn't just set there as one of the posters replied. What you would have is heat convection. To put it simply it would be like heating a pot of oil. The oil just doesn't sit there with no movement when you turn on the burner. The hot oil moves away from the processor and cooler oil moves toward the processor and so on. You would have a swirling affect and with that much oil it would take a long time to get it hot enough to be an issue.

Since you would have a continual saturation of cooler oil and the oil transfers heat more efficently than a hot piece of copper. i wouldn't even worry about cooling the oil before pouring it in.

The biggest issue would probably be sealing the case. I doubt the non- conductive oil will not damage or degrade any electrical components in the system. Therefore, that isn't even an issue and i wouldn't evne worry about it.

See how he used a heatsink on his oil cooled rig at tom's hardware... Just pointing that out, as you may want to look into a good heatsink that you can take the fan off of.

This has to be the funniest line of crap I have read to date about this topic. Just exactly how does a case full of oil dissipate the heat?

You are wrong, and unless you can provide any concrete proof to that statement, I will truely believe you have no understanding about convection, heat dissipation and the fact that all the components give off heat as well.

i gotta say, the test on the toms hardware link was pretty good, but with a feew modifications i think i could up the project a little, I wouldent use cooking oil id use special cooling oil, and also i would introduce a small self made pump. Also if it would be necessary i do have access to one of them big huge food storage freezers, but this is all still planned and i have to finish my time in the army first so id have to wait about 3 more months. But a nice project for experience.

[Chillaxed]

i beleive that guy, and if you do make sure you rinse ur components in oil or blow compressed air on everythign so that the oil isnt dirty

[901-Memphis]

Ye its gona be fun to make some sort of a pump/fan for that to circulate the oil.

Can you circulate the oil thru a 3x120 mm radiator used for watercooling?

Im not sure if the Danger Den D5 can pump oil too well LoL!

[Ghost742]

u mite want to use a thin oil like 10w-30 or somthing, if u realy want to get into it get a water pump used in homes for heating. there are cheap 1 hp pumps just look in home depo or lows.
and?or get a oil radiator like 4x4's have

[jointjene]

well like i have been saying the oil i am using is not vegetable oil or normal oil, this stuff was designed to run cool and stay cool and is extremely thin stuff nearly same as water, but its pitch black fro what i remember.
And once i have saved up a bit more money i shall post you all the pics and benmchmarks of what i am gonna try, alos if you guys could help me what the best o/c components would be, my budget is US$2000dont know if amd or intel will b betta. but thats what this forum is for.

I would not want to be putting 2k$ worth of parts into oil, but if you must, im sure you can take precautions to make it the best.

If you build the rig at the moment, intel has much better offering with their core 2 duos.

You should probably get an

E6600

2 gig RAM

7900GT

Asus P5 mobo

Something along those lines.

Do you plan on getting a high end video card? With that budget money well spent on an 8800GTX would be worth it. Especially if oil cooling, that card runs hot.

instead of moving the oil, which would be hard, use what is free!!!

get something that compresses air, like an air compressor, or an electric air mattress pump, have the outputs a couple inches below the heat sink. when the air is pushed out, it will rise to the top, and in the process move a little bit of oil in the process

[Ghost742]

i still think the hotwater pump would be optimal, u just need some copper pipes and u'd be set.
and if the oil is as thin as u say a 1hp would do fine.

How is it hard to move the oil? They make pumps specifially for oil, i believe they are oil pumps?
