hi

i'm planning on builiding a tec setup for my cpu (still in a very early stage)

do you guys give me some usefull pointers about the insulation (where to get the stuff in belgium), the tec itself (how mucht watt) and so on.

:hello: ty

search "peltier"

mucho info, very informational:)

You know the way to XS and XR, there should be plenty of info there.

some excellent info here also:
http://forums.extremeoverclocking.co...play.php?f=182

and this may help a little on where to get isolation materials; unfortunately, I haven't had much time to look around for these things because it costs way more if you have to buy it from a pc shop...

oh and you probably already know but you can use vaseline instead of dielectric grease but it becomes more fluid when it gets warm so it may run into slots and stop your hardware from working, it will usually not short out but you'll have to wash your board and let it dry completely :)

Here something about humidity in house, a very important factor.

This one is about condensationcalculation,dew point calculation, (dauwpuntberekening)

I found a good dealer in the USA , i did you a pm Nazaar. If you (or others) want the details , just let me know.

For example, a 130/170 Watt pelt, new for only 18.20$ (15€) shipping to Belgium inclusive.

This is what i'm thinking to build for starting with peltiers:

Greetz,

me wants to know too :)

some nice info you posted therer :super:

any chance of doing a group order ??

try also to contact the local velleman dealers. As they also sell TEC elements, but on a much lower price.

Velleman dealers only have some lower watt peltiers, even a 80 watt wasn't in stock.

Ok, here is the text from the mail he send me last week:

This was the reply on a question on e-bay auction.

"Sneaky" as I am, I did another mail to him, with the question if I could purchase direct to his comagny.
That was not a problem at all , and it was even a lot cheaper!
Here's the text of that mail:

Roel,

Yes, you can save money by purchasing direct. The price of $18.20 each for model CP1-12715 includes shipping to Belgium and there are no additional charges. However, if payment is made via PayPal there is a 5% additional charge.

If you want to place an order you can simply tell me the quantity, model and method of payment. If you want to pay via PayPal I will send you a PayPal invoice. If you want to pay via money order you can send payment to:

Michael Hollander
Thermal Enterprises
2 Shady Lane
Kendall Park, NJ 08824
USA

For payment via money order I recommend that you try using Western Union (www.westernunion.com). If you use Western Union it can be done online using a credit card and you can email the security code to me so I can collect the payment at my local Western Union agent. This is a lot faster than sending a money order in the mail.

As you see, its not a problem to purchase a lot of peltiers there. And a lot cheaper, compared to prices here in Belgium. Low Dollar can save you some serious money

;)

nice :)

I don't know much about pelts but someone told me the pelts had to be "potted" I think.

Do you know what it means and how I am supposed to tell the difference?

Also, I had a quick look on their site for psu's and they looked just like the ones from meanwell only meanwell has some 15V models (ideal to get the max out of your pelts I would think) and they didn't.

Potted= potentiometer on it (or place it yourself) so you can change the current (volts). The more volt (until you reach the max) the more colder it will be. But keep in mind that you must be able to remove the generated heat from the peltier correct, otherwise you gonna heat up the "cold" side slowly.

So that why i'm looking now for heatsinks etc...
Who nows where you can find large heatsinks? Or maybe a link to a site to build it myself?

a Thermalright SP-94 could keep my 172Watt pelt running for 10min:)

build large heatsinks?

well, if would think that if you intend to use a pelt, you would eather need a watercooling setup, or an insane heatsink/fan combo.

I also don't think that whatever heatsink you make yourself will be able to compete with what's on the market.

If you're looking for the best heatsinks: Thermalright sp-94 (P4) sp-97 (Axp) xp-120 (P4 & A64) and an unbearably loud fan; the price to pay for high CFM :)

So for fans, Delta and Vantec tornados come to mind, you used to be able to buy them both here: http://store.over-clock.com/Case_Fans.html but I see they don't offer the vantec tornado gamma anymore.

they also have pelts and pelt related stuff but certainly not as cheap as from the people you intend to buy from: http://store.over-clock.com/Peltiers___Accessories.html




*edit*
I knew when you explained potted that that wasn't what I read but I found the explanation again:

Watercooling no problem, I allready got a performant cooling now.
Like you say(and I now from my tests) the heat generated by those pelts is amazing, so i think I'm going to build another watercooling (separate) for cooling that pelt down. But its all in the designing stage, so time enough to talk about it.

Potted: sealed on the sides with silicone (water/condensation prooved). Are not al peltiers "potted/sealed"?
Otherwise it can be dangerous. Condensation inside/short circuit?

you're probably right but I know almost nothing of pelts so when someone who knows more of this then me says you need to get "potted" pelts, I take it to heart.

i have some experience with pelts too, i know it heats your water up more then you think. but if you have good block's and a good rad that shouldn't be a problem. feel free to ask some more questions

@Jort,

I was thinking to use a different radiator, only to cool the peltiers hot side, this also with a custom copper watercoolingblock (Same size pelt 50*50mm)
What's your opinion ?


Other parts (cpu/gpu/maybe NB 2 ) are allready H2o cooled

thats a very good idea, how do you going to make those custum made blocks?

but i don't see the idea of you.
you have your cpu, gfx, "nb" already wc cooled.
where you planning to put the tec's on? cpu? gfx?
so you can use the original blocks to cool the tec's.
or you like too use some other blocks too cool the tecs?

you can add me @ msn, if you have more questions(jortcollijn42@hotmail.com)
i rather like too talk in dutch :D

btw:
not all tec's are insulated. but if you insulate well you won't have short-circuit.

I sended you an e-mail with my msn-hotmailadres, couldn't find your's in profile ;)

I think he means a seperate WC just for the pelted cpu and his current wc for everything else

Correct Kristos, but I still need to learn about it, so all ideas are welcome.

ah k i get it now.
tnx for clearing it up kristos.
it is posible to have everything just in one loop.
just a rad that can handle everything.
what peltier are you going to use?

edit: i see youre won't too know what pelt too use too.

http://www.benchtest.com/calc.html
this can do mutch :o

check pm please ;-)

just calculated you cpu

stock its 68.30 W
oc'ed @ 2.2 ghz 108 W @ 1.9 v vcore

so if youre using a tec, youre planning of more oc'ing prolly.

so this one will do fine i guess
=> Model CP1-12715 (50mm/130-170W)

with 170W you can sure cool you cpu
its not the more W the tec the colder he gets
so if you have a good wc block an can get the hot side chill, you cold side would be -30 or less. cpu temps around -10 and 0°
i am just guessing.
i could cool my p4 2.6 ghz with @ 50 w tec till 0° idle and even colder but @ aida 32 nothing under the 0° is shown.

Is somebody going to buy from the site mentioned above? I'm very interested in that, it's so much cheaper then stores in Belgium.
The following link is an "how-to" to build your own TEC power supply: http://www.icecoldcomputing.com/
Nice site, check the 1kW waterblock to.

Im interested too ;)

I most likely will :)

when depends entirely on what the readout is on my bankaccount ;)

me to, be sure to tell me you guys will order !!!

This model suites me best i think:
Model CP1-12726 (50mm/245-320W)

With the TEC calculator my CPU will be 150W if he does 2.5 gig on 2V. Crazy!

:mad:
you have 100-150 w surplus :o

you don't think thats a litlle bit to mutch:^D

if you pelt is 200w and cpu is 50w=> your not getting lower temps(little bit).
the average delta T is the same so.

you just want to be sure you cpu is running cool enough :D

SiSoft Sandra says that my CPU uses circa 95W, and TEC's need to be double of that, so at least 190W. But maybe I overclock some more, so i need some space...

The hardest thing to do is to find a good cpu block (read: very very very good!)

http://extremeprometeia.com/forum/sh...=8453#post8453 ;) pretty much the best money can buy

only those using silver and custom built blocks are better.

review:
http://www.procooling.com/reviews/ht...review_-_1.php --> G4 (cupper base)
http://www.procooling.com/reviews/ht...review_-_1.php --> G5 (silver base)

in the reviews i can only read the delta T
but no actual temps:grum:

between some blocks
the temps could be 40-50° or 30-40° with 10° difference so.

not that the temps are that high just an example

did you try refreshing the page?

can you see this?

check this out :)

http://www.aquastealth.com/

also very cheap compared to the usual prices for pelts in pc shops

Not that cheap, but cheaper :)
80W pelt = 29 dollar
220W pelt adds 14 dollar, so 44 dollar.
And thats not sended yet...
If we are with few buyers, the sending is not goin to be much (3€ per person i think)

What do u think if this:
http://www.expresspc.be/checkout/shop/product/1146
Its in Belgium, so not much sending prices (for people from Belgium :p )

wouldnt it be smarter to order from that guy in the US ??

It's MUCH more cheaper and desert eagle allready did (so I think its save ;) )

I might be intrested, but i have to find some money first and I have a few questions.

First off all: I don't have a watercooling, what would you guys advise me for a decent price? So I'll prolly need 2 bloks (cpu & chipset), a pump, a rad and some hoses?

Second:
I calculated the overclocked wattage for my cpu: that's 124 watt @ 3,9 ghz. So I need a 120-170 watt pelt??
But how's that with the chipset then?

I have heard that the pelt power must be at least twice as big as the CPU power. So if u have an 100W CPU, jou need atleast an 200W TEC.
Don't know if its true, but i'm taking the risk. Besides, how more power the pelt has, how lower the temps if it is cooled desent.

Agent, just like u I have no watersetup. I'm watching out for second hand things. Then u can buy aan highend setup for half the price, and with little luck everything looks as good as new.
Dont forget to buy some good fans for your rad, cause u didnt mentioned that :)
If u are an die-hard modder u can use car-radiators or something like that. U can maybe make ur own blocks, and u will only have to buy an pump. Or jou can use a pump from a washmachine.
