Ok its time to go Pelt

[AmbientFiction]

I want a pelt. I want to for the time being air cool the pelt I have a C2 633 it will post fine at 980mhz but due to this crap PSU 250W ack!! I am having to lower it and lower it.

Ok I want to use a pelt with air cooling. I want to post as high as I can with this bad boy. So what do I need? Wats for the Pelt and what type of heatsink do I need to use. Also note I am going to water cooling when I build my AMD monster. So take that into though when letting me know what type Pelt I will need.

Thanks for any and all help.

If you're going to transfer your peltier to an AMD, 156 or 172. That would be overkill for your Celeron, though. It would probably freeze and crack. For a Celeron, a 72 watt peltier will suffice just fine. You'll also need a fairly good heatsink. What do you have right now? You may be able to re-use it. You'll also need a seperate power supply. That or get a better one. 250 probably wouldn't cut it. Alone, maybe, but with other compoments, doubtful

[AmbientFiction]

Gahh my 250 isn't cutting it now I am going to get an enermax 350W and is it possiable to hook up a Pelt on AC current?
I can regulate the Pelt right so even on the lowest setting your saying it would be overkill. I am thinking about going with a Cak38 or something nice and copper.

Bump anyone Bump Bump

Someone anyone

[FerrariF50]

No the Pelt is for Dc current only

[AmbientFiction]

I thought someone on here said they could be controled like a rehostat(SP) and also converted to run off Ac power

[FerrariF50]

and I thought I heard it burns out like that.....Well you have a spot open to try it.....You can me the irst to let us know if it runs on Ac or not :)

[AmbientFiction]

Ok well I wasn't sure if I heard that right or not maybe I was thinking of something else. So can the temp of the pelt be controled by a dial? Or is it one set temp?

Ok so where do I find one whit that many watts I can only seem to find the 72w modles via pricewatch.

Using a 172w or 156w Peltier on a Celeron2 633 is not overkill.However a suitable variable voltage DC power supply is highly desirable.The 24v 172watt animal(with a 25amp+,variable 0-25volt PSU) would be better choice for upgrading to an"AMD monster" because 2x172wPeltiers(40mm square) will fit on some commercial waterblocks and the bigger 50mm sq 156w animals will not.
Using a 172w powered by a nominal 0-15v Palstar PS30-M the peltier was consuming 4 amp at 12volt(48watt Heat-output), and 6amp at 16.75volt([6x16.75]watt Heat-output).Cooling a Celeron2 @1000 and 2.2v (50wattish) with a waterblock I was operating at 10-12v for web browsing at a cpu temp of 4-7C for gaming/stability testing at 16/17v with temps 13-15c.Although these are true measured volt/amp/temp they may not be representative because have subsequently discovered that I had a bad Molex connection to the peltier and you will probably find you can operate the peltier at slightly lower voltage(1or2V).

I am now cooling the same Celeron (@1000 and 2.2v) with a soldered(Molex free) 156w Peltier and waterblock .Specimen results are:- surfing 6v,5a,2C and stability testing 13.8v,12a,9C.

I realise that 2.2v(50wattish) is rather high for a Celeron2 but but it was need initially toget stable at 1000 and I still use this voltage for consistency of results and to maintain an above 0C cpu temp (avoiding,I hope, the cyclic ice-formation stresses under the cpu).

[It_The_Cow]

Well, using it at its full potential would. -30 C at full load and with watercooling. I didn't think about using a variable power supply. Anyways, try tedist.com and dangerden.com and check to see if it's in stock. They seem a bit scarce

[AmbientFiction]

Thanks guys. I'll look into it.

[AmbientFiction]

Ok I'm looking at peltiers at dangerden right now. I thought their was some type of controler box that comes with them. Have I been smokeing crack. I think I have missed soemthing. How the crap are you supposed to control the output of the peltier then?

No they dont come with a controller you will have to make/build one. Although if you bought a variable power supply it wouldnt be a problem.

I went through the same thing. I tried to find a way to make a variable pelt. I thought I could add a rheostat to the pelt to give my self the ability to "dial in" my temps. I finaly found a large enough rheostat online. It was four inches wide, 20amps. The thing was huge..and it cost 58 dollars !!! That was only just large enough to power a 80 watt pelt so you would need a rheo 3x bigger than that !! That's not going to happen...so don't bother looking. Your best bet would be to find a large variable power suply. It's going to be more practical then any rheostat or pot. You can find variable power suplies all over the place.

Thought you might be interested in this (http://www.coolerstar.com/peltierchip.html) place. They are selling 72 watt pelts for $9.99. Since you are running a celeron and only a 73 watt pelt you might be able to get away with running it off your psu assuming you get that enermax 350. Make shure you use a lot of closed cell foam to seal everything off.

Here's one solution:

Variable Pelt Controller (http://www.overclockers.com/articles424/)

I think he's changed per some of my suggestions, but I don't have a newere one to test out.

[AmbientFiction]

Ok maybe I should explane.
I am as soon as I finish my girlfriends computer go for the bigest air cooled system I have ever heard of. Its going to be close to either 300+ cfm or I might get ballzy and go for 600+ cfm. I was going to see how far I could push a celeon that is why I want such a giant peltier. Now what type of PSU am I going to need to run this peltier?
DRIFT-0.8 11.3 172.0 24.6 69 40 40 3.2 (potted)
Also I might need a way to dial the temp around. I am not sure how much the core can take before it cracks?

I hope this has explaned what I was wanting to do and don't worry. I'll let everyone know at OC what happenes if I crack the core or I if it takes off and I never see it again.

On a related note: can anyone tell me if a PC Power 300 watt PS would be sufficient to power a 172 watt pelt, assuming the PS wasn't doing anything else? I happen to have this PS in spare. Thanks.

[dmc]

I've been looking for a psu to power a 172w pelt myself. From what I understand you need a 24v dc 12amp or above variable psu. So far I have found none locally and a few online varying in price fron $140 to $400,a bit pricey but i'm still looking.
Good luck
Derek

[killem1x1]

Keep looking and you will find a power supply that suits you. I have an external variable, that costs around 350.00, but does evrythign, and anything, there are actually some $40.00 jobs out there, but ya gotta dig. Oh BTW $40.00 isn't gonna get you much except in the door ;)

[FerrariF50]

what the heck is a variable power supply?

[dmc]

I am new to this also so my terminology may be incorrect. What I meant was one that you can adjust the voltage. I guess the pelts have a sweet spot in the voltage where it doesnt saturate itself with heat. If the voltage is too high you cant get rid of the heat fast enough and you can overheat your cpu

[AmbientFiction]

Thanks for all the help guys it really means a lot. I am sweety and tired for I have changed my room around once again. Lugging a queen size bed by yourself isn't fun.

Now the comp is sitting in the path of the AC it should be soom cooler in my room but not much this AC sucks. I want winter and fast.

I try to be special It I try :D
