pelting

post #1 of 18
Thread Starter 
Having read NOL's TEC guide I take that something like a 245W running at 50-75% would be a good bet for keeping an OC'ed E6600/6700 at below 0º C, more or less nomatter what? Or would e.g a 80W be sufficient. Or am I totally off in my expectations on the pelts?
Is this btw. the right understanding of placing a peltier ->

Also, does anyone know of either a premade thingie, or an easy way to setup two PSU's in a way that you turn on #1, which has a 'terminator' and runs the pumps, pelt(s) and possibly other stuff as well, that then runs for x sec's before sending a pwr-on signal for #2 with the mb connected?
And vice versa too, so that it'll run for a little while after closing down OS/'term' signal for #2.
Or is the easiest just to put two custom pwr-buttons on the case and do it manually? The former is neater
Titan have this "extended cooling" gadget, but I'm not sure it can be tweaked to accommodate this behavior. And 5 minutes is a little too much I' say.

I have also been thinking how well the 226\\245 watt peltiers are going to cope with the C2D chips. They seem to run cooler so that is a great start. Your picture is the correct way for installation.
I use a mains pump so it is always turned on, then I don't have to worry about forgetting to turn it on. If by chance it is not running I have a temp probe on an alarm integrated into a fan controller for prior and quick warning.

Swiftech do some pre-made blocks.

Have you used any peltiers before, have you got a very good water cooling system now? Large efficient radiators and capable fans is a very good start.

If you fill out your system specs we can see what we might be working with

s'pose you mean "radiators and capable fans"?
But infact I've run neither pelts nor water I'm trustingly laying my upcomming mini-monster in the capable hands available here

system
Motherboard: ASUS P5W64 WS /Pro
RAM: OCZ Enhanced Latency Dual Channel Platinum XTC Edition (4-5-4) .. they say
CPU: C2D E6600/6700, not totally shure
GFX: XFX Club 3D GeForce 7950GX2
HD: 4 x Maxtor MaXLine III 250 GB, RAID10
Monitor: Acer AL2416Ws
Headphones: Sony MDR NC50 .. those are going to be SO sweet yer

liquid
CPU: Swiftech STORM Extreme Performance - Revision 2
+ some sort of peltier-setup.
GPU: AC aquagraFX 7950GX3
HD: 2 x Watercool SILENTstar HD-Dual
NB/SB: ? I read somewhere that particularly .. SB? tends to get hotter than the stock sollutions really can handle
Rad: Cape CORA 442 Concekt Midi Silver: (have)
Pump(s): CPU ~ Laing D5-Pump 12V D5-Vario 1500L/h, and then Laing D4-Pump 12V D4-Basic 1400L/h 'as needed'

err ... think that's it. There's a monitor arm too and a TerraTec Cinergy 400 USB for using this new machine and the big monitor as tv/video. And depending on how the pelting will be done I'm also a bit in doubt about the liquid. There's going to be pretty much heat to disperse, but the CapeCora is allegedly pretty efficient, and upwards 40% moreso with active airflow, which is how they're going to be setup. But likely as two pairs instead of one four-block.
But an option, if the Cora isn't enough, might be a homemade chiller with a second peltier venting either directly outside, or from heavy circulation fans that will anyway also provide airflow for the Cora, but the fluid will need to be with AF then I think.
And it's going in a wooden box, so I'll never hear a sound again That's what I need .. A monster, but a quiet monster

OH.. forgot PSU ... it's a 480Water cooled, which I hope will be sufficient for MB et.c .. cause I allready bought it And I have a 400W Fan PSU in my basement somewhere which I figured I'd use for pumps et.c.
[edit]and forgot to say it's PC6400/800MHz RAM .. I'm not good at this [/edit]

I've never seen a radiator like that, but you'll definately not want to try to run it passively.

I don't think a 245w peltier will run below 0 full load, but maybe at idle on a C2D. In fact, I'm pretty sure it won't. I've got a 437w TEC and have tried to get the absolutely lowest temperatures possible... On my 3000+ Winchester, I lowered my clock speed to 1Ghz, lowered my voltage to 0.6v and had my peltier running on 13.5v... Full load was -15°C. I'm willing to bet a C2D will produce a little more heat than an A64 at those power/clock levels. Also considering that the 437w peltier is almost double the power of a 245w unit, I don't think you'll keep in the negatives at full load.

It's stated at my hardware-portal, that C2D E6600 has a "Thermal Design Power" of 65W, a Sempron 3000+ 35W, and the FX-62 a whopping 125W.
[qoute=Pinhead-227]...my voltage to 0.6v and had my peltier running on 13.5v.[/qoute]
13.5 because of the "NOL considerations"?

I've also just been told, that the watercooled PSU may very well be the biggest contributor to water-temp. so purhaps that would be a good start to get less load on the rad(s) and thus lower CPU-temp, not putting that PSU in the loop and choose a regular PSU instead. As said it's going in a box anyways, so if anything wil be audible from outside the box, I recon it'll be the high airflow. Just that I already have this PSU, but I guess I can use it elsewhere.
A quick sketch of the box setup as viewed from the left ->
Not in anyway on scale I've attempted contact with Innovatek to get an airflow rate for their booster for the rad-tubes in question, 'cause they state in can increase the efficiency of the rad(s) by upwards a factor 3.
But in any case I should be getting lower CPU-temps when using even 80W peltier than just water, right? wrong ...

In fact ... if your 437W tec can't maintain a subzero unless downclocking, though then -15°C, my best/only bet -if I absolutely insist on the original wish for a subzero- might be something like MachII/VC-LS?

No, I'm just saying that the best temps I could get at those lowered voltages was -15C. On my X2 3800+ at 2.5Ghz and 1.55 volts I get -5°C load. On my Winchester at 2.6Ghz I was getting around -10°C load. I just used that as an example, as it would be closer to the C2D's thermal properties.

It's just got even worse Just found a uk dealer where many of the top pricers on my wishlist are available (a lot) cheaper than what I can find here in DK .. at least through my/the danish hardware-portal.
This means that I'm seriously contemplating quad SLI with two 7950GX2's. That way I won't have any graphic problems for the next milleni.....month ;-)
That would also mean that solely 480W is totally out of the question and something like 1000(+)W Quad-SLI PSU the only option.
I'd still prefer a dedicated PSU for cooling equipment though, regardless of what might be sacrificed, money wise, to get Quad-SLI and a large PSU.
There's also acceptable fan sollutions for the HD's, but that's even more ampage for the monthly bill ... the meter will go nuts

You basically need to be building an efficient loop that is capable of cooling maybe 4 computers. That way it will cope with the extra heat with no issues. Running a 437 watter with a x2 3800 with high Vcore would maybe equate to cooling 6 or more computers. You need to have the best possible water cooling loop you can build. It does not have to be expensive. I use a very heavy duty radiator the same as you can see in this thread with 3 fans on either side (push-pull). A 1800 LPH pump does the business with ease. I have no doubt that my water loop can handle generally any load. You need to be able to say similar for a 24\\7 operation.
