Ready for TEC, have a few ???'s

B2BigAl · 10-30-2003, 12:00 PM

Okay, I've gone about as far as I can with water cooling, and I'm ready to make the jump to Thermoelectric cooling. I've decided on the Maze4-1 setup with a 226w TEC, and a meanwell 320-12 PSU. My questions really concerns the rest of the components in my watercooling loop, well my GPU to be exact. My current w/c'ing setup consists of a Mag3 pump, 1/2" tubing, an 11x5/14x2 radiator with a custom shroud and 2 120mm panaflo's, a WW cpu block and a DD Maze4 on my 9800 pro. I'll obviously be ditching the WW block and using the remaining system to cool the pelt on the cpu. My question is, if I leave the GPU block in the loop, is the heat from the pelt going to make my water to hot to effectively cool the GPU. If so, I'm planning on upgrading the Maze4 GPU block to run an 80w pelt. So my next question is, can I run the 80w pelt off my Antec truepower 430 PSU since I understand you can't run both pelts off the meanwell. If I can, are there any good articles on how to rig up an 80w pelt to a regular power supply? And finally, what kind of temps do you think I can acheive on my 2500+ (running 2.53 GHz @ 1.93v)? I'm getting idle temps ~33C and load ~39C(temp probe mounted on backside of CPU.) with 26C ambient temps on my current wc'ing rig.

Cmon guys, I know you can answer this. I really want to order my stuff, but I wanna hear from the cooling experts here before I do. Any input, anyone... :shrug:

Ill try to give it a shot...

Run your cpu 2nd after your gpu. The 80W wont put too much heat into the loop before you get to the cpu. The reason I think this is easily do-able is the cool side of the cpu is in direct relation to the heat taken away on the hot side. Therefore since you are applying WAY too much cooling to the cpu (unless you like ice) then the hot water from the gpu (not much at all comparitively speaking) you should be fine. The entire setup stays in 1 loop.

As for the meanwell, why cant you run both off that power supply? The 226W wont draw everything that has to offer, and the 80W isn't a heavy hitter. In fact using the variable power knob on the left hand side, you can turn down the voltage to ... 15%. Now you can ignore me.. but my preference isn't to get to -15C but somewhere around 15-20C.. as close to dewpoint without going over. Thats come good overclocking, and you dont have to worry about water dripping when you turn off the pc.

Thanks for the reply winewood. Why do you say I'm applying way to much cooling to the cpu? I thought you were supposed to get a TEC rated for at least twice what your cpu wattage was, 108w in my case. Also, how can I run both pelts off the meanwell? Since the one pelt is only 80 watt and the other is 226watt and the meanwell only has a single output (is that right?), wouldn't I either have to severely underpower the 226w pelt or severely overpower the 80w pelt to run them together?

The output is just screw clamps, isn't it? You'll have to solder wires onto the TECs regardless, in order to lengthen the leads (I recommend high gauge wire, like 12 gauge), so when you are doing that it is relatively trivial to wire up the two TECs in parallel.

As to condensation prevention, it's not a big deal if you do it correctly. I would recommend getting an MCW462-UHT if you're worried about it, because Swiftech provides the condensation proofing.

As to temperatures you will achieve... that really depends on a large number of variables, so it's impossible to say beforehand.

winewood · 11-01-2003, 02:02 PM

Ah.. I get it.. ya. If you are underpowering the 226 then you wouldnt want to under power the 80. Shoot, just hook the 80 to the PSU and the 226 to the Meanwell. As for doubling the wattage calculation, I haven't considered that as my goal isn't pretty frost but just lower temps with as little condesation as possible. But again, it is your setup, and without knowing what your goals are the advice here may not be what you were expecting.

As for the 108 Watt power... I understood that to be a max output for some of the higher end procs, but nothing that is going to be represented over 1% of the cpu ontime, unless you are folding or such. I tend to think to address the power output that is there 90%+ of the time. What is the exact output of a cpu running 80% idle? I have no clue. Thats why testers are using a die-sim to test, as its very difficult to know for sure.

A 226 is capable of cooling anything, but almost a shotgun approach to defining exactly what cooling is necessary without having excess. Even using a 24V 172W pelt, I understand that it runs most efficient at 85% power.. 18V. By turning down my 24v meanwell it runs EXACTLY at 18V.

Thanks for the input guys, much appreciated. Do you know where I can find a guide on how to rig up the 80w pelt to my PSU? It seems like it should be pretty straightforward, but this being my first time doing this I don't want to fry anything. My goal is pretty simple, get everything as cold as possible without frying anything due to condensation. I was going to get a Vapochill, but I just invested $200 on upgrading my watercooling system and another $250 on a new case and fans. I didn't want it to go to waste.

I think this will help you. Pretty strait forward. Remember google is you friend.
