1 degree over ambient NO HEATSINK..

1 degree over ambient NO HEATSINK..AND NOW THE OC

SO is 1 Degree C over the ambient temp good??

WITH NO HEATSINK??

mobo temp is 24C
cpu temp is 25C

Amd Athlon Xp 2600 Barton Core

Liquid Cooling.. NO HEATSINK!!

zip22 · Apr 22, 2005

im guessing thats not load. whats it look like inside? are you chilling the water?

dracos · Apr 22, 2005

no not under load....

And there is no heatsink.. and it's not water... that's why it's in 'Extreme Cooling' section..

about to run Prime 95 now...

Look like inside?? did you look at pics?

zip22 · Apr 22, 2005

are you gonna tell us what it is?

dracos · Apr 22, 2005

NOPE....

Can't actually.... NDA....

but I just wanted to share results...

direct die cooling with non-conductive liquid?

Yeah that is what it is...

Prime 95 NOW..

Mobo 26C
Cpu 31C

True, you don't have a heatsink; you have a waterblock. That waterblock is not of the conventional style, but I would still consider it a waterblock. You don't have to hype it up for us to think it's cool. Just say direct die, because that is what it is. Btw, this isn't technically extreme cooling either. I think the category "extreme" is defined as sub ambient temps. The lingo around here would classify this as direct die water cooling with non-conductive coolant.

Anyways, nice results. I have a feeling your temp sensors are a bit wacky though. Did you make that block yourself?

Could you link up a bigger pic. I want a closer look. =)

I wasn't trying to hype it up... Sorry if it appeared that way.... I just wanted an 'eye catching' title...

and yes I made the block and everything myself..

actually my temp sensors aren't off on that board, have a few other sensors I used to verify.....

and Oh well.. Extreme to me is something 'Not water' or not 'air' something out of the ordinary...

What mobo is that, you do know that temp reporting on a mobo is not accurate at all right? Also, since you are completely soaking the area, I would think that you are also liquid cooling the temp sensor as well. It would be nice if you could attach a thermocouple onto the corner of the die and put a quarter inch cube piece of insulation on top of it so you can verify the temps for us.

If you are using the fluid I think you are using, then technically you have a phase change system. (I see you have more bubbles coming out than going in.) Thats a hundred bucks well spent.

Good job.

I would agree with that idioligy. Why does it have to be below ambient to make it extreme?

I see extreme cooling as something different, maybe new, and effective that isn't mainstream. :shrug:

Looks good, I have considered such things, but haven't had the time to make the idea be more then on paper.

LabRat23 · Apr 22, 2005

Why does it have to be below ambient to make it extreme?

The sub-ambient rule is the easy line to draw, because it is not subjective.

Here is a thought: If you put the rad after the pump and add a restriction between the rad and the block, you might be able to get sub ambient coolant. That is if there really is a phase change happening.

dracos · Apr 22, 2005

Actually I have more bubbles going in that coming out........

those pics were taken early on when system was not quite bled enough...

and this fluid is $250 per gallon...

and actually those temps are pretty close to accurate.. I have an external temp sensor placed into to fluid and it is reading the fluid at 28.1C right now under load..

blackjackel · Apr 22, 2005

hey having liquid flowing above below, all around, and inbetween the processor seems extreme to me...

Its EXTREME cooling and not FREEZING cooling....

Your watercooling setup rocks, and IS EXTREME, keep it up.

Aphex_Tom_9 · Apr 22, 2005

well, it's been done, but not often, and you seem to have done it very well. nice work.

enduro · Apr 22, 2005

Wow, that's awesome. I've only seen cooling like that once before and that's when a guy submerged his entire motherboard in the nonconductive fluid.

blackjackel · Apr 22, 2005

If i dont have the balls to do it...

Then its EXTREME.

Lets put it that way

ZachM · Apr 22, 2005

Don't get me wrong on what I said before, this is very cool. Dracos did a very nice job. Yes it is out of the ordinary, and I would say it's extreme, but the description for the topic says "Peltier and Phase Change Cooling", which I interpret as well below ambient temperatures. Anyways, I didn't mean for this to turn into a pointless debate on whether or not it is extreme cooling, so I'll end it at this.

Very nice job on the direct die cooling, very clean block design.

Welcome to the forums as well :welcome:
