140Watt Tec Vs Q9550

[Vatos_locos]

the molex is temporary just to test it and the wires are solder to the tec module so they should be fine
i plugged in the psu just to test it as i'am waiting for a meanwell SE-450-15
as for the wires to use with the meanwell the are 4mm silicon wires so there is no prob
it will be isolated but this was just a mount test :p

those are the wires

[Vatos_locos]

i have a question
will this psu be able to power correctly this tec ?

[Ultrasonic2]

Should do .. that tec is 177watts of cooling that nothing ..you need more power

[Vatos_locos]

you boys have to decide how many watt ( Qcmax ) is that tec
one says 226 another one says 177
lets assume that it is 226 will this meanwell hold it ? or souled i go for the SE-450-15

or i didnt understand nothing ? ( i wrote it before my English sucks )

the link you posted says it's 177

yes you are right i havent noticed that :/ because someone in the first page told me that this is the most powerful tec 50x50 anyways i will try with this one to see how it goes and if it cant handle it i will buy one more powerful

[repsol_23]

I think it was post 12 that I refered to a peltier on the arcticspider website. As far as I know that is the most powerful 50x50mm tec, it was listed as a 340 W tec @34 V and 437 W tec @48V. This is the one I have. It is running off a meanwell 24V/20A psu and it keeps my x6800 @ 4.0 Ghz w/ 1.47V below freezing at full gaming load and just above freezing when benching. Although this is done with a chilled loop on the hotside with fluids ranging from -5C ~ 20C depending on local dew points.

Unfortunately, arcticspider no longer is a registed website so you cant access the information for the peltier but there is a forum post here that talks about it: http://www.overclock.net/peltiers-te...han-360-a.html

Hope this helps!!

You should check out this TEC... Works really really well at 12vdc and it's what I use to run @ 4.4GHz... But then I only have a dual core e8400. Seems to be a pretty good alternative to the ones already listed here...

Also if you have plastic threaded bolts for your cold plate use them. The metal bolts will form condensation from the cold plate touching the warm block. I've heard a few people here have problems with that causing water on the mainboard/in the socket.

EDIT: the 12726 is okay IMO but the unit below seems a little more powerful

If your looking at 12711-****-**** designation this a specific Custom thermoelectric part no, there are quite a few starting 12711.

The part listed is still a 12726 - 127 couples rated at 26amps.
Not all manufacturers give exactly the same specs the Qmax for 12726 can vary between 226w and 245w depending on who writes it and also it depends if it is quoted at 25ºC or 27ºC.
There maybe a slight difference in performance due to quality of build but in the main a 12726..... is a 12726.
Some parts come in 2 sizes.... the 12726 is one example...it comes in 62mm size and a 50mm size they both have the same output for a differing surface area due to the different density at which the couples are packed.

EDIT - And a 12726 is not the most powerful 50mm you can get.

VATOS check this out - they don't have a greek distributer (sorry USA.) so the min order is $25 (allowing you to just buy one. It used to be $99) this is the cheapest most powerful 50mm i know of.

This is the page - http://www.hebeiltd.com.cn/?p=z.peltier.pricelist
and this is the part TEC1-26316HT (300w Qcmax.) it is the last one right at the bottom of the list. $22.90 but you will pay a small premium for a small order. Shipping was reasonable and fast China to UK 3days after payment clearance.

OH NO...sorry it is a 30v part...might give you a bit of a problem...but fitted my requirements perfectly.

The highest Qmax 50mm TEC I've seen is here: http://www.huimao.com/series4.htma However I wouldn't count on being able to find it but that is the highest Qmax 50mm I've ever seen.

i'will thanks everybody

Yeah I've noticed that too. Very good point. For me though, the 15vdc part runs really nicely @ 12vdc. Producing about ~220 of cooling at this voltage. Enough to keep the e8400 at about -10c idle which is nice...

So it only consumes 390 watts but moves 245 watts of heat? Not bad, over 60% efficency.

[flak-spammer]

Unfortunately it's barely enough for most quads that people have. Since we have the problem of 400w + 160w = 560w to dissipate assuming a quad that someone has overclocked (why else would you get a TEC ). Something like the 245 slightly undervolted isn't going to be enough to get subzero load temps.

You think that's good......

This thread is really informative. Thanks folks!

I've never used a TEC, but I was considering it since PHII processors seem to like staying cold.

I've read the "Sticky" section and a number of threads in this forum.... I actually have a very strong WC system (homemade) and I thought this might be a good option to at least keep my CPU closer to ambient or hopefully a little below.

Maybe I'm wrong, but I'm getting the impression that modern high wattage quads (> 100w) might be tough for TEC's to handle.

I just want to get an honest opinion, is it worth it to continue my research into this option for a chip that may be pulling upwards of 130 watts?

Thanks...... Dave

[Vatos_locos]

nope the one i got can go about 10 below ambient with the Q9550 overclocked @ 3.7
but under load with the water it self i was getting better temps @ 4.2Ghz :p

[flak-spammer]

You might be able to do okay with a 400w Qmax TEC. However you won't have a huge amount of room if you plan on doing crazy overclocking and such.

[overclocking101]

if you were getting high temps before this tec i think it's your waterblock it's self its old and out datefd i think if you want to add a TEC you will need a better blobk to cool the hot side, remember the cooler the hot side is kept the colder the cold side will be. i personallly use the swiftech TEC block they sell with the meanwell kit they used to sell and it cools my Q6600 overclocked to 3.9 around 14c load

[Vatos_locos]

i'll try with another block if i get a chance
there is not mutch time for me to play with my computer at the moment

[Daveburt714]

Thats what I was afraid of....

As for going with a 400w Qmax TEC, I'm sure it would be fun to play with for benching sessions but the cost and power consumption for everyday use would make it a little unrealistic for me.

Thanks again for your input folks!

My 190 watt quad runs about 20+ degrees cooler than with just plain W/C ,when cooled buy a frozen CPU 62mm TEC .. i think thats worth it but thats my opinion
