What will you use? peltier, conductivity, or lquid?

i tested a very cheap peltier thing on a amd xp 2100. Turns out i used the wrong side. It fried, lol it was cool. It used so much power too grrr.

anyway what will you choose for oc.ing? Classic air? New lquid? or Freezing peltier


P.S The 2100 was already burned.

Thats an open question. I dunno what i WILL use but i plan on submersion or vapor exchange :)

FYI ur not supposed to just use a peltier by itself........
 
My budget is telling me i'm using a massive heatsink and a good CFM fan...

But if i had the option and cash wasn't important i'd probably go with a mix of water/peltier. Water for looks and to cool NB, vid card, HDD. And Peltier for CPU most likely. An odd combination but i bet it would work pretty good if i could keep case temps low and the rad cooled off since the peltier will get pretty hot in there...

Well i assume you dont intend to use the peltier all by itself....

lol no, i was thinking i might use 2 of them, 1 for CPU and one for NB. They make really small ones but i'm not sure if it would really be better than water, since it would be producing alot more heat than water would and probably give ~ the same results. But i dunno...it may be miles better. After i get my new computer and have had it for a while i might consider it, until then i doubt i'll need it. The new processors run on little voltage and low temps...

Uh .. you do know that if you just use a peltier by itself, CPU or NB or otherwise, it'll end up burning itself out right? Modern peltiers are not like those of the Pentium2 generation heheh

no i know that, you need a copper cold plate and some kind of cooling for the back side, i thought u meant something else i guess...
 
for now im using WC(CPU/CHIPISET/VC) but im considering PHASE CHANGE fo my next rig if not for my current one.......no budget yet for that though, and prolly get a prescott to see how far i can OC, mwahahaha. :cool:
 
Refrigeration/Phase-Change: Not for the light of heart or wallet phase-change systems can obtain temperatures of -50 or even lower. This system uses a four step process to cool. A gas (usually Freon) is sucked into a compressor after phase-changing (from a liquid to gas) in the evaporator. The gas is then pressurized until it turns back into a liquid and flows into the condenser (a radiator) that removes the heat caused by the evaporator and compression. It then goes into a thin copper tube known as the capillary that lowers the pressure before reaching the evaporator. Once in the evaporator the liquid absorbs the heat and turns into a gas once again. Commercial systems that do this are made for 'reasonable' prices by VapoChill and nVENTIV (Prometeia).

* Advantages: Possible -50C temps, commercially available.
* Disadvantages: Very expensive and large power requirement.
* Required Materials: None if commercially bought, if DIY: Refrigerant gas, compressor, condenser, evaporatpor, capillary tube, housing, and HVAC training (reccomended).
* Price Range: $800+ (VapoChill LightSpeed)- 1,160+(Promethia Mach II GT)
* Example: VapoChill PE
* Would you like to know more?

im not much of a science guy so this is what ived read about phase change. :)
 
Well unless that one German company is ressurecting things, Promeia is dead, went out of business a few years back...

The important thing to know with phase chance coolers is that really, you have to heat the stuff around the point of contact or else you risk condesation extraordinarie :P

So to answer my question - yes you are talking about a vapor compression cycle ;). To debunk a few things in that statement Freon (which is just the commercial name for R12) isn't used anymore, R134a is. Second, they don't consume that much energy, well, if you're cooling down to -50 it might. Finally they aren't that expensive if you build them yourself. I have a compresser sitting in my closet that I could hook up a couple HXs along with a throttling valve and have a cooler (slightly oversimplified).
 
I got some link on DIY phase change...its too long so i got lazy reading it, its gonna be helpfull if i do decide to DIY but i dont wanna jump into that yet.
 
Yeti: as I understand it, Freon is still used -- just not the same Freon as we've all come to love and hate (i.e., its an environmentally friendly variant now ... perhaps it goes by the name R134a?)
 
Thats the thing - its not actually Freon. Freon is a trademarked name (I believe its DuPont) referring to R12 (CCl2F2). Other refrigerants are commonly called Freon mistakingly (kind of like PATA being called IDE, I guess I should reference computers somewhere in this post :D . Actual Freon is still used but as far as I know only in unindustrialized nations due to things like the Vienna Convention and Montreal Protocol. Alright, I stop talking about this. I'm sure no one really cares and its a bit off topic :o .
