Guess you can cool an i7 with TEC's

[Elloquin]

I should have an update tonight or tomorrow sometime. Still trying to get all the 2d benches for HWbot done at 5G's. I can run them all at this point save 32M still working on that one Shame really one or two sticks of my CAS 8 Corsair Dom GT's gave up the ghost. I have to use my back up GSKILL Tridents so the timings may be a little weaksauce

32M 5G's

[malkiewicz]

Now thats a nice OC for a 920 without LN.... What's your max temp while running Super PI?

[Elloquin]

Thank you Mal. I am trying to knock off the big tests first as the water temps get saturated after a while. The Gskills aren't playing nice lol and the result is not very efficient. If I can get wprime 32M and 1024m run at that speed I will be very very happy lol. I killed the OS getting that so I need to re-image and then I will have at it again. PI 1m will run at those speeds no problem so I will make sure to at least get the temp reading for that On that run the cores were running in the mid to high 20's max. I would have taken sceens along the way but it took a long time to get that to run so I didn't want it to crash :P

[Elloquin]

Wprime 1024m, 32m, and 5G's boot 1024 is a PITA.






Still tweaking efficiency is poor as expected.

[NaeKuh]

are you chasing vcore with overclock... or are you just ramping vcore + overclock?

When you get to sub ambient... you want to race voltage with overclock.
Because of the lower temps, your cpu will be a tad bit more efficient, so you shouldnt need the same voltage to get same overclock at a sub ambient temperature.

The only time u ramp voltage + overclock is when your major major under sub ambient like LN2, where u know your gonna get the best efficiency you can and shoot for the highest overclock.

ultra:block looks very sharp mate

@OP: nice clockage

[nipps]

that is all true but nylon or polycarbonate screws aren't strong enough . which is why as far as i know no one uses them. i also tested them and they were a fail

i took apart a tec cooler once and they used little plastic washers that surrounded the screw in the hole and then a nut on top so there was no metal to metal contact...

[Clay]

I'm sure this design would work.... If you used spacers within the block this would prevent thermal transfer....

I like this.. I think Ultra's hot plates screws,screw in from the bottom of the block though. And a plastic washer would also be needed to help further isolate the heat. So there wouldn't be anymore countersunk flush-mounted hot-plates. But there some pretty flat, flat-headed screws out there.. I think this would help some.. And "Muffy" could still countersink the washer. Wait!! Actually he could still make the screws flush. But that would be quite a bit more work.

Muffy? I like that.. It's cool..

Edit: 4x 240 gtx rads saturated? So I guess I really will need a third and probably a fourth rad.. NP....

Edit2:@Elloquin: Are you still cooling with tec's?

[Ultrasonic2]

i have probably made more changes to the mounting hardware of my blocks than anything else

the block at the beginning of this thread was the second block i made so a few things have changed.

While malkiewicz seems like a good idea it not practical for me because the block would need to be wider to accommodate the sleeves. and a wider block is not desirable when trying to fit to your motherboard. Also the above design would result in condensation forming on the bolt heads as they would be sub dew point

Currently i just reduced the pressure applying bolts which is the obvious way to reduce losses and these bolts dont actually touch the water block but a still warmed up to prevent condensation

the main reason for not using all the bolt holes to apply pressure to the TEC is so i could apply more pressure to the W/B / cover seal to prevent it from leaking.

The reality is that the TEC's need a relatively low mounting pressure

[Clay]

I really like the new block. So now 4# hex bolts to hold the cold plate to the water block? Plus the mounting hardware helps some... Iron/Steel doesn't really transfer heat all that well. And those look smaller than the earlier version too. And as the block itself will never get much hotter than ambient.(If I can help it!!) Heat transfer really shouldn't be much of a problem. I would like to see more examples of other computers using your blocks. So I can get a better idea of what is needed to cool them. But I think I'm on the right track. ( Load-Total-Overkill!!! LOL)

Answer to your first question: Yes I still cool with TEC's but I am more interested in getting the coldest load temps I can as opposed to the 24 x 7 thing.

Answer to your other request about these blocks running on other computers...you won't. Well you may see a test or two done on a q6600 but that's by far outdated. To my knowledge I am the only one out of several to actually successfully (meaning get it running with decent temps) run the block on an i7 platform. My block is also made differently then the one above in that the base design is different. I also do not use and/or endorse the use of Chinese TEC's.

Ultra is in no way associated with myself or the block other than the fact he machined the block or for its actual performance numbers. Hell most of the changes you see in the new block were suggestions I made to him ages ago.

If you have any questions I would be more than happy to answer them privately as I have grown weary of Ultra advertising in my threads.

Agreed

The second block i made went to Elloquin and he gave me significant feed back and as a result of his findings i made a number of changes

There is little worry of me selling anything as we both know i haven't really sold anything to date. If i had people would be posting about them.

Anyway Ellopuin is a great guy

[Clay]

Don't worry too much.. I really do think you'll sell one sometime in the fall.. Maybe sooner... Well have to see...

yes you can cool you setup with TEC :

idle :



Temps under load :
