that must put TREMENDOUS stress on the fans.

That looks really sweet I must say. Nice post.

Im making the attempt. Would you even need fans?

No you don't need the fans. In fact, I don't think I've ever seen anyone use fans when building an oil cooled system. You really only need to do this if you plan on overclocking the crap out of your system, or you want a really quiet one.

Imagine how messy upgrading would be.

got an old P120 that I've got to try this on. Tell us how it went eric3579 !

I beg to differ, pretty sure you need fans to circulate the oil. Did anyone notice how long it took the system to boot?

well they booted before adding the oil.. so what about it? It might even be slow because they hadnt added the oil yet, and no cpu fan?

Fluorinert would be a far better choice for doing something like this... (3M site link)

unfortunately, it's also rather expensive:

250 cc bottle = $135 ------ plus shipping (ships 3 lbs.)
- Nextday Air shipment within the US $28

I wonder how well the heat dissipates from the oil itself. I tend to keep my machine on all the time, and not knowing if the oil can manage that without any cooling for itself is a bit worrying.

Actually bothered to go to the website which they advertised at the end, and found out that it seems to transfer some heat out of it self, but not enough for my needs: "While you could add some radiators and pump the oil through to cool it, you realistically would not be gaming constantly for 12 hours, so these temperatures are as extreme as it gets for this system.", is what they say, but 12 hours of constant gaming is realistic, at least for me, even though very rare AND I can come up with many other things that I need to do now and then that put heavy stress on the machine for long periods of time. But in any case, the 12 hour endurance test raised the oil temperature to over 80 degrees celsius which is WAY too much. For a Linux box or such this would be perfect though.

I didn't even know it was possible to do this.

I too would think that the fans would be severely stressed by this, they're only built to push air, not viscous oil.

The slow boot was with their old test equipment. Their 2nd, final machine booted fast.

I'm not so concerned about the fans as I would be about hard drives. I'm assuming that you would have to keep drives (that aren't solid state) outside of the box. Am I right on this?

Yes I think that's an external HDD on the left. With a little more work you could put it into the aquarium cap.

There is no stress put on the fan. There may be extra stress put on the motor, temperature wise, but no other sort of stress. The oil should take care of that

I'd take the fans off, and put an aquarium filter into the box (that would pump it around)

you could even pump it through a bar fridge freezer if you were keen..

In addition to the initial boot being on old hardware, as Sketch pointed out, it also was booting the Ubuntu Live CD. Live CD's are slower than an installed OS mainly because of two things:

1. They're loading from CD/DVD which is quite slow when compared to a hard drive.
2. They create a RAM drive and expand their file systems there, thus reducing the amount of RAM available for normal use.

obviously a fake.

Well, don't strain yourself to elaborate, Peroxide, heh.

The only reason this even remotely interests me is because I hate noise. If this helped me have silent computing I'd buy it. The weight , mess, and lack of portablity make this sort of worthless IMHO.
