tec question

[Ghost742]

so pelt/tec's are pretty cheap right???

would i be able to use one with my zalman9700?
can i conect it directly to my psu?
what tec/pelt would i get for a e6550.

thanks

1) Yes they are cheap. 2) No. 3) Maybe but I wouldn't 4) None. Don't get a peltier till you learn more about them.

There's a nice sticky on the top of the page that easily answers all your questions....

[Ghost742]

ya and its the length of a bible, y would wouldn't i be able to use it on my current air cooler i have see it done with the 120 xtremes.

the titan is also a air cooler with a pelt(even tho it sucks)

and all i was asking is what wattage would sufice

[onewecallgod]

It's long because there's a lot to learn about them. This isn't for lazy people.

[Ghost742]

i dont think theres much to it. i have been looking through the tec form for as long as i have been here. never made a post in it until now tho.

il just go with a 100watt pelt and see how that goes

heres from the sticky:

- The Formula to Determine the Delta T (bet you wished you had paid attention in algebra) -

Delta T = (1 - (Heat Load/Max Cooling Power)) * Max Temp Difference

Here are a few examples with difference watt TECs cooling a modern processor which usually generate around 60+ watts of heat. Practice the formula on at least one of these examples before calculating Delta T for your own project!

*) A 40watt TEC cooling a modern processor generating 60-watts of heat. Delta T = -34C (negative 34C). That’s an INCREASE in temperature on the cold side, so the processor would have been warmer than before! Using an under powered TEC can destroy the processor. Cooking your CPU with your TEC is NOT a good thing, avoid this common mistake.

*) A 226-watt TEC cooling a modern processor generating 60-watts of heat. Delta T = 51C. That’s a decrease in temperature on the cold-side, making the cold-side 51C colder than the warm-side.

i hope that sums up the parts you need to know fast before u make the mistake of buying the wrong one. ive played with them before and as great as they are at cooling, it takes 10x the care as compared to water cooling (due to condensation), which alone is 10x the required care as using a simple heatsink and fan (due to water leaking). and just to help u with using one on a heatsink, the second example i posted says 51c difference on each side. so if your heatsink kept your cpu at lets say 60c load, with the peliter if it kept it at 80c load thats only 31c drop in temp, not 51c. it takes alot of cooling power considering to use it your looking at over double the heat to remove.

[Ghost742]

well a 226 watt tec is a bit much don't want ot go sub ambient because of the hassle of condensation proofing .

[ricecrispi]

Too lazy to read, too lazy to condensation proof, and too slow to realize you shouldn't be fooling around with pelts.

Have you seen the air cooled pelt HSF performance. They lag behind tuniq tower or 120 ultra. My advice is sell the 9700, save the money you would've spent on a pelt and get a Thermalright ultra 120.

So my final advice is leave pelts alone until you want to invest more time and energy into it and buy the thermalright ultra 120 extreme.

with an air cooler, tecs arn't worth it. TECs should only be used in water cooling setups (anything higher than that, you might as well get a phase chnger or chilled water setup)
TECs that are low in wattage are basically useless and won't be that great result wise. The air cooler would heat up VERY quickly too. Becuase, if you didn't know already, the heat taken away from teh cold plate is put onto the hot plate. making htat like.. 90 C or so.
I personally wouldn't advise pelts unless you have a wc setup
and even with that, you better have some money
getting the peltier plate itself is cheap
it's the power supply that kills
and the water cooling kit which isn't too bad

[Ghost742]

i figured it would put a rheostat in the line before it connects to my psu,
that way i would be able to adjust the amount of cooling, i could go with a
higher watt pelt to, it would still draw w/e amps it needs but i could control
how much wattage the sucker puts out. but w/e if u guys think it dumb to use a pelt on a air cooler then i wont.

[avgazn91]

I don't think it is dumb, I'm just not sure if you would be happy with the results, I wasn't happy with what people told me i could get using my 9500, for the amount of money you put in.

[Ghost742]

what money a tec a rheostat and some washers for more clearance

[avgazn91]

the powersupply if you ever get one, is like 200 to 400 bucks

[Ghost742]

why buy a power supply when i wave 3 more rails with 18amps on my current one. 12vx18A is 216 watts

[ricecrispi]

OKAY?

Just do what you want and learn the hard way. Just have fun and good luck.
Maybe when your finished with this experiment the biggest thing you get out of this is learning to listen to other people's advice.

[avgazn91]

i have personally never tried and never will try hooking it up to my pc PSU
it makes the PSU more unstable. It's safer to go with a separate one. And i had a 850 watt SLI compatible one. but then again, i never did it, so i don't really know what it would do to your computer

[carbinefreak]

i just got over that ordeal, my psu could handle it but i forgot everything that i ever learned about wiring and i only used one molex connector SO that melted.....long story short if your gonna use your computer PSU make sure that that you A. make a custom cable so that u use AT LEAST 4 molex connectors, i was reading the tec sheets after mine melted and the max current per connector port is 6A, OR B, remove one of the molex chains form your psu pcb and solder in a custom 14ga copper stranded wire and solder an heat shrink that to your TEC's leads then you should be fine.
Good luck I'm gonna try the latter when my silver stone psu comes
happy moding, as usual a computer PSU deals with LARGE voltages AND Amps so BE CAREFUL and discharge ALL CAPS before you start if you screw up its not my fault take all advice with a grain of salt. and i am not liable for anything
good luck

[Ghost742]

thats the most helpfull post so far. i suspected a molex wouldnt be able to handle the current.

[carbinefreak]

Ya... the most a molex connector can take is roughly 72W within specs, but you can probably push 100w with good circulation but i would watch it.
