The temperature of the cold side depends on the temperature of the hot side. The peltier creates a temperature differencial between the cold side and the hot side. so if the hot side gets hotter, the cold side will also get hotter.
Peltiers are very inefficient... if u run the peltier at 12v@320watt, the hot side will have 320watt of heat from the peltier plus lets assume 80watts from the CPU. thus the cold side cools 80 watts whereas the hot side has 400 watts of heat to be cooled. You're gonna need a good WC to cool the 400 watts of heat.

well just to prove metalzone point on pelt

Test Setup
x6800 3.2ghz 400 x 8 @ 1.3 V
Gigabyte N680SLi Dq6 - Stock Voltage on Chipsets
Team Xtreem PC2-6400 3-3-3-8-1T 2.35V 1x2gb
Coolit Freezone At Max.
Ambient Temp Around 36C... freaking hot afternoon just now.

(Ambient temp by the metrological department of malaysia is conducted in shaded area .. to check the temps of air and not to be influence by uv rays etc )

Core 1 Temps [attachmentid=237061]
Core 2 Temps [attachmentid=237062]
Mobo Temps [attachmentid=237063]
Vcore Reading [attachmentid=237066]

Verification [attachmentid=237068]

Idle temps are good but load a different story
Actually performance wise i would say get a tuniq tower with Silverstone FM121 and u can beat this except for some reason my mobo temps are much much cooler with the coolit and therefore i can overclock the bus speed right to 480 at stock voltages on nb,fsb everything...

Thanks for the info, is anyone here running a peltier in the cpu's on a daily basis?

So in this case the Coolit Freezone operates by cooling the liquid that flows through the "water" block rite. interesting concept. But from your bench marks it doesnt seem to really cut it.

Nice tool this OCCT..thanks for intro'ing it...cheers

anyone else willing to share the pic of the setup with peltier?

caution dudes
occt is fine and dandy but still i trust in orthos

i use occt just for the graph thingy with speedfan to check out when the proc fails what the vdroop was...and from there adjust my vcore.
overclocking made easy...kekeke..

btw check out op1000 ..kekek and some volt mod on this mobo... 1.3 all the way..kekek without any fluc at all.
also btw theres a temp sensor on the 9inch fan..
it wont let the freezone to drop the temps below ambient.

Added on May 27, 2007, 8:12 pmpast few days i keep wondering if the temps are like it was stated above..

y the freaking hell i keep having condensations problem.
the water block is like freaking cold and has signs of a bit of condensation on idle... l
and the coolit the blue metal part like having water vapour on it.
and the water tube thats going in is also very cold.

theoritically if the water that goes out from the hsf and comes back in the difference is the estimation of how cool it is...

so i put a temp sensor like smack in the middle of the water block... idle 23 , load 35...

so anybody can explain to me this??
is core temp wrong???

Wats the temp when condensation happens?

anything below ambient and u start having it thas why ur ice milo aslo ada condesation

Umm... Roughly how many degrees below ambient will get?... Im setting up a air cooled pelt lol... Wana run the proc abit higher than ambient... And... Is pelt reliable?... later i run a while only the pelt fail my cpu fried... haha

well once u get below ambient condensation starts,, thats why ur room if u on aicon.. then off hte aircond and open all the windows u get condensation.. even at 1 degree below ambient. although the condesation is not much..

btw pelts are abit too outdated.. not worth the the effort

I was thinking about that too... I scared the pelt fails and bye bye CPU lolz... So I think I shud make it into an air cooler instead... By cooling air then blowing into the HSF...

bro seriouisly the power draw and the performance is not worth it.. unless ur going to serious pelt.. beter get phase change...

Yea when you get down to it phase change is better than peltier considering they draw the same amount of power. Phase change is not easy to set up though.

This post has been edited by wodenus: Nov 21 2007, 08:46 PM

phase is not easy to set up.. its only the building time.. once the system is fully built its easier than watercoling to set it up . only need to mount the cpu block from the phase change to ur cpu and do some insulation adn ur done. no filling and bleeding time.

Yup that's what I mean.. If you want one you'll have to build it, get someone to build it or pay Prometeia's prices

where do u get plasticote brand?? been searching like hell

hmm.. may i know where can i get the peltier plate?
i went to lowyat and looker around
however, the shops told me that they r not selling peltier cooler anymore

You can try garage sales as there is someone selling

can u run a low power pelt with aircooling to achieve slightly better temperature than just air cooling?

From what I read, you need bigger wattage pelts to cool CPU's which are made these days (eg. 226W). Other things to worry about is the insulation so as a conclusion, it's quite complex I thought of trying but gave up the idea after a while.
