Just saw a new TEC cooler on retail. It's in the latest issue of Custom PC. MACS brand. Quite interesting. This TEC thingy is a Pelt isn't it. A bit confused by all the different terms. It's just a simple looking HSF n it's powered by ure PSU.

So sorry to lambat reply, Yup TEC aka ThemoElectric Conductor (yup its not a thermoelectric cooler cause a TEC is actually a heat pump) is the same as a Pelt or Peltier(Peltier is the name of a frenchman who discover the TEC properties)

I'd like to quote from CustomPC:


and i'd like to quote my self.. ehem, ehem: alamak my "choosing the pelt guide" is gone ledy. Here is where its supposed to be:Choosing The Pelt Guide.
nvm i'm quoting neway:

Aiyaaa. That review was done in 2003. N different product oso. The MACS one I saw is on the first page of the July issue of Custom PC. I managed to find it here oso http://www.scan.co.uk/Products/ProductInfo...roductID=204877 Mebe the technology has improved over the past 2 years n now better than the AC4G?

ok, sorry bout that.. diff'n design/make but same princple... so as the "Thermaltake Sube Zero 4G".. .. guess you've read all bout it in Xtreme Computing Review. In that reveiw they're comparing the MACS wif TT Typhoon and AMD stock.. well .. Even your Corsair Cool's can whoop this MACS clean at load temp man... again like to requote:

either or, pick your poison man... like to add: for modern day processor (Post 2000) it is highly recommended to use at least a 220W Pelt for Barton Core and a 320W Pelt for the Presschott core... for the 64bit platform, sorry i hadn't had the chance to play with any yet... maybe soon

I got a regular peltier i need to run, but the problem is, all my spare PSU are OUC (out of commision) or KIA (killed in action) .

Is there any particular power adapter or some other ingenious way which i can use to power up the peltier? Besides buying a new PSU of course . Any help is greatly appreciated =D

If it runs on 12v you can just get a DC adapter (the ones used for external modems, walkmans, etc...) at any local electrical shop, however, the max amperage I have ever seen was only 1A, I'm not quite sure wether that would suffice for a peltier...

maybe you can try using power adaptor/transformer for halogen lamps. they run on 12v with 20w or more(fixed wattage per adaptor)

hmm.. my peltier is rated 70watts, so that would means i need approx 5.8A right (12v peltier)

0.o does PSU actually able to supply that much?

bonjorno...hey antonio.. no problemo, let me sort out a few things first before i'll update this thread with some calculation on choosing the right pelt.. plus plus a few comment about w/block suitable for pelting and those readily/commercially availabe pelt+w/block in the market... cause the "puasa" month i won't be doin any travelling muahahahahaaa.

thank you mr otai san... UGPM.

ok.. for a start please read this link first regarding choosing the pelt: cause i'm lazee to re'taip' me other "choosing the right pelt guide".

1. The Ultimate Guide to TECs

THEN yread this one:

2. TEC undervolting charts

ok? ani questions please post ere so we all can share the answers.. currentli i think aleck is another one who is actively using pelt to cool off his rigs.

O.T.: like what happened to all the "y" in this forum?

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 Achieve

First 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.

Okay, hope the guide above will help. Now for those who have the moolah (RM) to get a commercially availabe Pelt KIT, there're two manufacturer who can offer these readymade kit. Let's look at two "old school" competitors:

1. Danger Den with it's DD Maze 4-1
2. Swiftech with it's MCW5002 XT series

Well both of em are using the same assembly design which is:

W/Block + Pelt + Cold Plate.

Previously however swifty is using a rather radical direct water cooled TEC block, but it seemed the product is no longer available for the cpu TEC, oni the VGA TEC cooler is still using the older assembly...The Swifty MCW462 X T series (heh guess swifty realize the Maze 4-1 design is better).

Please take your time to go through the reviews.. and lets discuss ere.

Here is a simple java based program i made.
I called it Peltier Estimator
Its useful for those that interested in getting peltier, and had a hard time to calculate from those formulas, here is an application for you guys

Screenshot #1 :


Screenshot #2 :


note:
1. due its a java based application, so you must have Java Environment to run it
2. if any miscalculation/ bug found, feel free to PM me

1 Q bro amok....

issit when we get the 'moolah' peltier kit from lets say for example swiftech...does all the hassle of insulating are required??? or does it chill it to a level which does not create condensation....such AI does it exits??

Well, once your pelt temp drops below ambient room temp, condensation will occur.

Unless you wanna cool your proc ngam ngam to 30 degrees celcius........

, nice one evogenix, Need to emphasize that the Pelt wattage after calculation is the wattage needed to dissipate by the waterblock. Good job ,hope everybody knew hot to run java apps.

And i'd reckon the calculation has taken into account that the pelt is ideal (meaning running at ideal/rated volt and Amp e.g. 12V, 20A etc.) Good job again , i like it.

anthonio@ as long as you're runnin yer rig below dew point, condensation will occur be it with pelt or phase change.

What happends when this motherboard.....



combined with a modded version of the....



which means i wont be using the blue heatsink or what so ever except for the TEC device which is i've taken out aledi....

and as for safety....



and



wil be used...(Thanks to ARJ for directions of getting those stuffs.... )

Yesterday started my "Cool Cool Babeh!" project...Achieve interesting temps too...Aint frost...but cool enough....here at the pics...No benchie were run because of my rams aint being much good yesterday...need setup again...aiyakkk...



this is area which i had clean up my room again just to make sure safety is a must...and the fume from the electrical tape can make u high a bit if too much is inhaled...On the lef of the LP box is a monitor and a left of the monitor is a window..



This will be the TEC cooler from Thermaltake which i'm going to use to get better temps....



the preparation was done abit 'kelam kabut' bcoz i need to use the pc for work file trnasfers...arghh..



I was shocked because when i was pouring the electrical tape on to the mobo....i remember i poured on just near the section of the socket...then suddenly nature calls....when i return i notice it has been spread out until the capasitors and the rams slots area....aiyakkkk....

I noticed on the capasitors there was a brownish color being mixup with the tape...what is that?????



Arghhh..without wasting much time....i quickly continue work and forget about the brown leaking capasitor....i reach for the dielectric grease and pour it on the socket....rub untill each corner has been dielectric greased....

.. keep em posting anthonio sorry for my absence. Any prob pm or post here. k.

By the way whats the pelt wattage? TQ
