Well, this is as much that I can salvaged from a previous deleted thread regarding pelt usage, ... I hope to share some knowledge and experience with other forumers who had use a pelt or venturing/planning into using one be it on you proc or gpu. I hope that those who'd experienced with pelting their rig would share you knowledge with us. A word of advise: Please Use A Watercooling Set to cool off your Pelt. This is just a rough guide for choosing the right pelt for the right purpose. SORRY NO detail explaination such as:
1. What's a Pelt?
2. Characteristic of TEC Material (pnp or npn).
3. Kirchoffs Rules.
4. How Pelt work.
5. Eddy Currents or Freddy Krugger or Darth Vader etc. etc.
In another word this will be all in layman's term

. Those of you with ample or great knowledge in electronics can spare the details latter on when replying to querry posted here.
O.K. enough of this camel dung lets get to work. (Let's try to make it sweet and simple)
1. Things You Need to Know Before Starting.a. Stock Wattage/Power of your current proc.
b. Stock Voltage of your current proc.
c. Stock Speed (GHz) of your current proc.
d. Estimated(angan-angan) Voltage of Overclocked proc.
e. Estimated(angan-angan) Speed (GHz) of Overclocked proc.
f. Estimated Wattage/Power of your Overclocked proc.
For a, b and c you can get by the label of your proc's box or through their manufacturers site. But for (f) you need to do a little bit of calculation.
Estimated Wattage of OCed proc = Stock Wattage x ((OCed Speed)/(Stock Speed)) x ((Oced Voltage)/(Stock Voltage))Square
or
f = a x (e/c) x (d/b)Square
There you go. But if you're lazy there is a simpler way which is by clicking
this Power Calculator..

(Hahaha). Once you got all the figures jotted down move to no. 2 below.
2. What temps you're planning/Dreaming to AchieveFirst of all, Pelt is NOT as efficient as how people tend to believe. So don't, I repeat, don't put to high hopes that your pelted rig will perform the way you'd planned or calculated. Usually it tends to be only 65%~75% efficient.
O.K. you've got the figures in No.1 above. Let's find the right pelt for your oced proc.
First rule, the maximum theoretical delta T (max temperature difference) between the hot side of the pelt and the cold side of the pelt on ALL TEC pelt is around <69C.
Second rule, the higher the wattage of TEC rating (e.g. 40W, 80W, 120W, 220W etc) the higher the percentange for a TEC to reach the max delta T.
Lets see how the actual delta T can be calculated:
Actual Delta T = (1 -(cpu wattage/TEC wattage)) x Max Delta T or
Actual Delta T = (1- (f/TECwattage)) x 69C
Confused?
NVM lets look at an example: Samy wanted to oc his 1700+Tbred to 3Ghz. And using a 220W TEC pelt and max Vcore is 2.0V From the calculation on No. 1 His Oced Proc Wattage (f) = 180W.
So His Actual Delta T
= (1 -(180/220)) x 69C
= (1 -0.818) x 69C
= 12.55C
Meaning samy has succeeded in bringing the temps of his cold side 12.55 cooler that his hot side. Easy isn't it. Yeah but remember the 65% inefficency? So his actual Delta T is 12.55 x 65% = 8.175 C
Let say samy got an ideal/perfect W/Cooling set that can bring his hot side to room temp (lets say in Malaysia about 28C)
thus with this pelt his proc temp will be : 28C - 8.175C = 19.82C.
(providing samy can find a that ideal water cooling set).
I guess thats about it.

, before buying your pelt please make use of the calculation above in determining what Wattage suits you, don't simply buy and regreted later. Pelt isn't easily available here in M'sia. I guess alot of us learn it the hard way.

(But not me hah, hah, hah)
3. Powering the Pelt.Very simple... don't use your rig's psu full stop. Use a dedicated one, no matter how impressive or expensive your antec, enermax, thermaltake or thermalright or thermalleft, TEC draws a lot of current!!! and they're inconsistent. I can use up this whole thread trying to convince and explain to you about not using the same psu for your rig and TEC Pelt but i won't. Google lar

, no need to be spoon fed right?
So a meanwell S320-12V is too expensive? ok lets try a decent psu with a normal 12V rail.
Actual Current = (12Vp.s.u/Pelt Vmax) x Pelt Imax
Lets say samy is using a 220W pelt wif an Imax of 25A and Vmax of 15V
Actual Current = (12/15) x 25A = 20A
Then again the efficency of you pelt will be lessen by 20% thus effecting the Wattage of you Pelt to 80% of 220W = 176W pelt. Dissapointed eh?

welcome to the darkside beb.
Well I guess that cover most important part in choosing the right pelt. If anyone had any good link please post it here so we all can refer to. Till then good luck.
