TEC Coolant Chilling Device - plz add your oppinions!

post #1 of 46
Thread Starter 
Yo chaps, putting together a lil experiament with a extra heatsink and water block ive got laying around:
http://www.leelambhomes.co.uk/OC_files/thedevice.jpg

run the toasty water through the water block which attcached to the cold side of a 80W pelt, which has its hot side on a zalman.

1) where in my water circuit should it be most beneficial? (pump > cpu > gpu1 > gpu2 >120 rad > 240 rad > haetsink res > pump)
http://www.leelambhomes.co.uk/OC_files/DSCF1355.JPG

2) what kind of effects do you think it will have? good or poor?

3) any other suggestions? i.e change a peice of hardware?

i got a 80W external psu (the plastic black brick transformer type, like a laptop charger) this was the highest wattage silent psu like this i could find if you know what i mean....next step up would be a chunky ugly 1 with fans.....so i got a pelt to match

Well, it hink this could really work, especially if you gat a little bigger pelt, and a more powerful air cooler on the hot side of the TEC. Like a big typhoon, and a 226w pelt. Then have the cold block in the loop right before the cpu. It should lower temps atleast a few C. But it surely wont hurt temps! Worth a try!

Insure proper contact with the old zalman cooler and the pelt. Maybe it would be smart to lap both the water block and the old zalman first.

Give it a try... im moving into the world of pelt cooling soon, and i would like to know how it goes.

I had just suggested using a similar method to pelt your H20 loop. Heres what I have been looking toward using, in combo w/ a 227w TEC.

Here is a thread where one of the pelt guys was using a fan to cool his pelt...I know this is a different concept you are working on here, I just thought you might like reading it...Good Luck with the chilling.....Ultimate Air Cooling - Overclock.net - Overclocking.net

You would really be better using another water cooling loop to cool the pelt, but if your just using whats available, there isn't much of a reason to not give it a shot with your zalman.

Personally I wouldn't get a bigger pelt using that cooler. That zalman probably isn't capable of dissipating any more than 100TDP. I'd personally put it after your radiator, because thats where the water will be coolest and allow the TEC to run most efficiently, because then you have less Heat to transfer out of the water, so your zalman won't have to work as hard to keep the TEC + water cool.

Loop order doesn't matter since water is flowing too fast to actually heat up in a particular location. The inverse would be true as well and cooling location won't matter. Just place the TEC+waterblock+HSF in the easiest location.

I thought Zalman listed those as 300W capable? I tried to find the spec's this is all I could come up with. If some knows how to convert this, please post.

The water will have greater internal energy after energy has entered the system at a specific location eg. CPU Block. In the radiator, the Heat is transferred out of the system into the air. Therefore after the radiator, the internal energy of the water is at its lowest. The flow will determine where the heat is transferred to within the system.

However, it is a DYNAMIC system. The maximum temperature delta of the loop is less than 1C. How long is the "hot" water in the waterblock? Less than half a second. How much additional energy does the molecule of water absorb in that time.... a marginal amount. There are no hot water points in a loop since the water is flowing so rapidly.
