I'm going to buy a TEC of 600W

[Jochenp]

Can I even keep it cool with regular watercooling?:eek:

[bestmancajun]

I thinking of stacking two 320Watt pelts and in the same boat...

[Mr. Tinker]

Where are you getting a 600W TEC?

[Jochenp]

Ebay, 50€

[marvt74]

Watercooling could cope providing you had the right stuff.

Might require a custom block though as doubt a Maze 4 would be able to handle it

[Holst]

Ebay, 50€

Dont trust the specs posted on ebay, they are often totaly wrong, or misleading.

Got a link? (PM it if your worried somebody from XS will outbid you)

Im not aware of any company that has made a TEC with Qmax of 600watt, although there may be one out there somehwere... must be huge though 60mmx60mm at least, probably bigger.

[n00b 0f l337]

Well if you run it at 600W your going to take a slapping.
What's its max voltage?

Thats what it says.

[UnreaL]

Do I read a big 360 in there or is it jsut me?

[Jochenp]

Whats the difference between Qmax and what they say it is?

[Holst]

Qmax is the maximum ammount of "energy/heat" that the peltier can pump between the two sides.

Or put another way, if you load a TEC upto Qmax the temperature differntial (delta T) from side to side will be zero (the TEC wont do a thing)
In this case if your CPU load was 320watts the pelt would do nothing at all.

This value Q-max is how computer TEC people normally list TEC size.

The 600 watts comes from the power you need to supply to the TEC to make it work. 25volts (vmax)and 24amps (imax)
(v*I=Q) 24x25 = 600watts.

But this 600 watts also assumes that the TEC is full loaded at 320watts.

With a CPU on the TEC at (say 100watts) a lesser wattage, the current drawn by the TEC will also drop, often quite considerably below Imax.
You should allways use a PSU capable of delivering Imax or you risk blowing up your PSU, even if the running amperage is considerably less.

SO for this TEC you need a PSU of 25volts capable of delivering 24amps.
You can run it at a lower voltage, which will increase efficency, but will decrease cooling capacity.

[Holst]

T max is the highest temp drop you can acheive with this TEC.

This is the temperature differential between the sides of the TEC when running at Vmax with NO LOAD on the cold side of the TEC (also insulated)

This is a pretty pointless figure as we allways have a considerable load on our TEC's

[Rey overclocked]

i just got this for an experiment =) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=ADME:B:EOIBSAA:US:11&Item=7587032962
i have a spare 450 watt pc power supple i think i can do about 230 on the 12v rail is there a way to hook it up to there ? anything i should look out for ?

Doesn't Tmax also assume 0C ambient?

[Holst]

Im not sure to be honest, the conditions are usually stated in the spec sheet.

It might be standard lab 20*c.

Im not sure it would make much difference to the results, but it would have some bearing.

[Jochenp]

So is the tec a no go or is it one of the bigger tecs available?

[Holst]

It will still work, 320 watt is plenty for a CPU.

[Rey overclocked]

someone please correct me if im wrong, but you can get one similar to the one i posted with has a 350 qmax and is 15v @ 30amps which requres 450 watts of power in comparison to 600!!!. or you can run it at 12 v and get 270w. its a bigger tec so if your usuing it for your processor i would go with a 50X50 since you dont really need the larger surface area for a that kind of use. again im a little new to actually using tecs so if someone knows better please correct me.

[vikikz]

Hmm, people have problems to cool a 226W pelts and you want do it with 360W :/

[Holst]

I think this is another case of incorrect specs.

This is most likely a unit with 220watt Qmax..
They are all 50x50 15.3v, or at least mine is.

[Jochenp]

What setup should I buy? I just can't decide between TEC's and chilled watercooling. I have an old freezer right here, but it seems so difficult to get it all righ, while with a tec you just put it in between.
And isolation seems such a hard job

[Revivalist]

I think this is another case of incorrect specs.It seems like that happens a lot with TECs.

[Rey overclocked]

It seems like that happens a lot with TECs.
i dont see the incorrect specs. i mean just becasue your tec is 220 watts qmax and 50x50 deosnt mean they all are. and for most pc aplications you dont need anything more then that. but there are 62mm tecs that go way beyond 220 w. but maybe im wrong and so it the guy who i bought mine from and this giude i found. http://www.overclock.net/peltiers-tec/59153-nols-tec-guide-guide-1-basic.html
but liek i said earlier im new to tec cooling and maybe there is some ruel i dont know about. but dont mock jochenp or me for being new and take some time to explain why the specs are wrong or why he cant cool 600W with his water cooling.

Please don't think that I was mocking you or anyone in this thread. That's not in my heart at all. . . . I'm also new to using a TEC (only had these for about 4 months), and even if I was experienced, I would rather help others to learn rather than mock them for not knowing yet. . . .

Anyhow, I think Holst was simply stating that the specs on the TEC are probably incorrect, and that this is something that happens often. I was just agreeing with him. In fact, this happened to me. I bought the TEC on my CPU thinking it was a 320W TEC. I didn't realize that it's 320W only in ideal cases. In reality, it should be called a 245-320W TEC because the actual performance will actually be between 245-320W depending on how well it is cooled. But I was still happy because I'm probably still getting at least 270W dissipation with it, which is what most people use on their CPU. . . .

Anyhow, I hope things go well with your setup and please don't hesitate to ask questions. I have found most people to be very friendly around here. :)

[Rey overclocked]

lmao thats true, the 600w tec from the specs has a 58% eff meaning you can use it to heat your house in the winter.

yeah reviv your right i didnt mean it to sound mean or anythign but jochenp has been asking what he should use and kind of ignored him.

Jochenp im new to using tec but ive been readin on it for a long time and usually ppl will use a 50 x50 220 - 270 tec with a water block that has a wide cooling area but anything above that usually becomes inpracticle.

the reason i bought that huge 320-270w tec is to use it undervolted but mainly cuz of the larger surface area wll benefit me in what im going to do. but for a processor i wouldnt go with anything too big.

[Jochenp]

I will ofcourse use the so called 600w tec (if i ever buy it) underpowered :).
Thnx for the feedback guys

[Premmer]

[QUOTE=Jochenp]So is the tec a no go or is it one of the bigger tecs available?[/QUOTE
Have a 437W TEC and 600W PS available if your interested.

[Jochenp]

I live in Belgium and shipping and border costs almost double the price of anything that comes oversea.

[menlatin]

Make a water block out of this http://www.shopcircle.net/Ebay%20Auction%20Pics/G8113/G8113%20(Medium).JPG to cool it.

[Jochenp]

Erm, why?
And what does it have to do with the TEC?
Waterblocks with heatsinks on top of them are useless anyway, thats why a lot of waterblocks have plexi tops.

[[XC] MarioMaster]

600 watts?! Sheesh for that much power I could run my 5000 btu air conditioner. I think at this much power TECs become a bit unpractical.

?? not WB and heatsink, i mean put the heatsink in a plexibox with only base exposed, run water through it and cool the pelt with it. Do you not remeber, back in the day, the waterblocks that came out that were cpu heatsinks encased in plexi. Aluminum ones turned out to work GREAT compared to simple copper blocks.
