pal, i think that these are pretty weak pelts with low amp needs. so i thought 15aQuote:

Your talking about 190 watts and 16 amps total...
Lower V is usually is not a problem on a pelt, but lower amps aint a good plan.
(plz some one correct me if i'm wrong :P i'm not the expert on it but i know certain basics :P)
The difference is low, so well, its not gona explode but the tecs might not work optimal or dont workt very well at all
am building a tec setup and i have a 13.8v 30 amps power supply, now what would be the most powerfull 40 x40 tec i could use ?
probably any 40x40 tec u want... 30amp ps is a lot :)
the problem is the low V from what i can c....
havent found any 40x40 that do sub 14v
50x50 226w would work excellent on that ps
btw 3x0
from the tec faq in this forum:
-Dangers to be Avoided (stuff you don’t wanna do) –
The biggest danger is attaching a TEC that is underpowered; many have cooked their brand new processors doing this. :cry Of course, this is easily avoided; just don’t attach a TEC will less cooling power than your CPU generates.
i have been looking around for a high watt tec who would run well @ 13.8v but they all seem to need 24 v
i have a 227W tec that runs 15v with 15a :D
but its 50x50mm... still great tec :) can run it on my fortron psu with 12v@15v :)
For those of you with a bit of experiance building circuits, here is a link on how to build one for cheap http://www.overclockers.com/tips1054/
maybe that article addressed this, but why would a powersupply for thermoelectics even need filtering? why not isolate it from the mains and then full wave rectify it?
Are there any PSU's that are capable of running two of these without making me go broke?
Uhm...let me see....the amount of electricity consumed is based on the TEC, not the PSU....you would need a sufficiently large PSU to run it...but the PSU would only consume enough to power the TEC...see how this works?
So basically, the TECs would make you go broke if you ran two of those, if you need THAT much cooling power...go with phase change water cooling...it's far cheaper.
Hey guys, i have an idee for a TEC supply. Most cars today use alot of Ampére. My 1100cc even has a 40A 12V battery. What u can do is use one of those, or maybe u can use a car battery charger. My dad has one and it can output more then 100A @ 12V i think.
For benching that is. I don't see someone use that kind if supply in their cases :D
I have this as a second PSU:
Does this mean that if I mod this PSU I can get the 12v line up to 15.6v without a problem? Could I power the TEC @ 15.6v with this single PSU?Quote:

Hello. :)
I have a 170W(50mm) TEC with an operating requirement of 0-15V and 0-15Amps. I am planning to use a spare ATX PSU with a 12V rating of 15Amps. But since SHROOMER said that a PSU runs best at 75% load, and assuming that the 12V rail of PSU may flactuate to about +-5% of 12V, then the cooling power of my TEC will be:
min cooling power (Watts) = (12V / 1.05) x (15Amps x 0.75)
= 128.475W
max cooling power (Watts) = (12V x 1.05) x (15Amps x 0.75)
= 141.75W
If my calculations are correct, then I could say that the PSU will be sufficient enough. The cooling power of 120W - 140W is also sufficient enough to cool my AMD 2400+ processor.
Are my calculations correct???? :confused:
Will the PSU overload??? :confused:
You might want to go for a bigger TEC than that. People are using 172W TECs on video cards these days, not CPUs. Something like a 226W unit would be better.
Guys i know almost nothing about tecc cooling. Only the basics. So with my cpu(intel pentium 4 s478) what tec should i use? I want over 226w. Where can i find it?
Also which psu should i use in order to power that little monster...?
eBay, and as big as you can get. :)Quote:

They say you should look for something (probably from a reputable manufacturer) that has 20A+ on the 12V line. That should be enough.
+20A @ 12V, that will probably be a 400 - 450W supply
But watch out, your 300W tec could use different voltages and current. My 240W TEC uses 15,6V 26A, but there are TEC's that use 26A @ 25V for exemple.
Just search what the max U and max I for u'r TEC is, and then search for a supply.
Just now i spoke to a friend and he said that he could give me for free a 400W psu from a case that he bought. The case is aopen. I dont know the amperes jet but, generally, i believe it shoyld be enough... :stick: :confused:
Also although a part of it is greek, what do think about that ferrotec in the middle. The only thing that concerns me is that its 40x40 and not 50x50...Also its imax is 15a...if i powered it with the psu mentioned above, i wouldn't get the best of it. Correct? I am confused ... :confused:
http://www.checkmate.gr/products.php?cid=12
Technical data for Ferrotec TE-9505/127/150B:
http://www.ferrotec.com/usa/thermoel.../products2.htm
Imax 15V, Vmax 17,5V
With that 400W supply u will not have the maximim 147W Qcmax, since u can have only 12V.
:( Ok then. What if i used redkens psu. It says that its 12Voutput is 13~15,6...then i would be ok right? Also, which is best, 40x40 or 50x50?
Never mind. I found my psu. I am going for it. it is this one click me This is all in greek so, i am transelating...it is capable of 40A, and i can manage the volts from 5-15. and it is weighting 2,1 kg...
Any increase in voltage is better, as long as u don't give it more voltage then Vmax.
40*40 or 50*50 does't make any difference I think. But check if u can fit 50*50 under your heatsink/waterblock. If the heatsink doesn't cover the intire TEC's hot side it would not be cooled good enough resulting in bad functioning of the TEC.
The only thing that counts is Qmax. The higher Qmax, the better the pelt will cool (if u can cool the hot side enough).
Ok thanx. I would buy a custom block but he cant make one right now. So i will go for a maze4.
Do you guys think an Aerocool 550W would be enough to power a TEC rated for 320W and 26A @ 15.3V? I would run it at 12V and the power supply's +12V rating is 25A (that should put the amperage draw from the TEC to around 20A, right?)
Thanks for any info. :)
