Heck, I would'nt tear it up for a temp probe anyway. Your bench will let you know how far you can take it...I seldom read temps unless pouring LN2.

(Btw, Jor-El has his cpu in as well when it flowed into his socket)

Yeah, but I'd really like to know the actual temperature of the block/IHS. It's not that hard to remove the block, I just don't want to mess with the cpu, cuz then I need more skin...or to learn how to use the eraser.

If my chiller bath is -33c, what do you estimate my quad core is running at?

My pump died because I was running it on 5v for hours. I'm such an idiot sometimes. Gotta get another pump tomorrow...going to get a 12v marine utility pump @ 200 gallons an hour from harbor freight for $40.

Computer crashed and it took a few minutes to realize why.....finally I got it running again @ default settings and then notice the cpu was @ 63c and the cores were @ ~85c in HWmonitor. It didn't want to run overclocked when it was hot. :keeporder:

Good Night

This pump I got is loud as hell, and doesn't work for shit. I have a quiet submersible one on the way now. Should be here this evening.

I admit I reduced the fittings out of necessity, but the hole that actually goes through the pump is smaller than my fittings. It's sucking water .........it sucks my finger up tight to the hose, but the water is just not getting out the other end through the waterblock I guess. It's only trickling out and it's supposed to be pumping up to 4 gallons a minute w/ 50psi.
Anyone know about pumps? I'm going to try a submersible fountain pump, although I am kind of skeptical about it.

The lowest my cpu went was 21c with this pump installed. It was running 4-5c with the other pump that was obviously doing a better job.


BTW...do you think the previously mentioned temps could have hurt my cpu if only for a couple minutes? I'll find out later I guess.

I would solve that blockage problem before worrying about anything else.

Take the block apart and clean it out.

It's not clogged, the pump just doesn't have ass enough to push the air out. Simple as that. I even just removed the block and pump to assist in getting the air out and it didn't get it all out. seemed like it was pumping good. hmm going to go with the submersible I guess...less air problems I think and quieter.

Is it possible that I fried the chip and the temp sensors are now out of whack? EDIT: nahh it's the air.........It's at 30c right now and rising slowly. Air is so fucking frustrating.

Yeah I have only WCed a few times... I build the rig up with enough slack in the hoses that I can move pieces around while the pump is on to bleed the air. (flip the rad 180 degrees for a few minutes. Tilt the whole rig to the side then the other side...

Never took more than 10 minutes to bleed a system after my first attempt./

But I also never ran 4 blocks in a loop ;)

I just have the cpu in there. But the air in the return line is like a brick wall. I have no idea how I got the last pump going.

With my gpus I have the res above everything and it just bleeds right out.

Here as you can see the end of the return is downhill. If I put the return through the side of the cooler it would work great I bet, but that's a lot of work I don't plan to do.:ohcrap:

I should just let a few gallons out and put a hole through the side, then the air would have nowhere to get trapped. Simple solution, pain in the ass to do. I think I'll try the submersible first though as it should be much quieter.

I'm going to have the same problem with the submersible in the return line. This blows.

Ahh... I see it now...

Yeah you are going to have to keep the pump input line below water level. Not a big deal really although right now it will require removing the liquid from the loop. With a big daddy pump in your last pictures I would not think it would be a big deal as long as you prime the feed line. But... bleeding would be tough.

If there is nothing coming out of the output, there is nothing going in the input. Pressure does not mean much if it is vapor locked by a big ole air bubble...


In theory....


if you have about 3-4' of intake hose inside the cooler... fill it... put your thumb over the end of it... put it all back in the cooler under the water... power up the pump wait a second or two and remove your thumb.. this should provide enough liquid to keep the circuit going.

Not a water cooling guy, but do have some experience with pumps.

you could also use a small pump to prime the feed line for the big one until the loop is bled (should only have to do it first start up...)
