Tec Voltage/wattage Chart Options

[Gray_Mole]

I 'nicked this from bl**dy Sorcerer from over at XS forums, thanks mate

It's not going to be 100% as it's worked from formula Q=2*Qmax*I%-Qmax*(I%)^2 where I%=volts/VMax but is really as accurate as it needs to be to figure out if your TEC is gonna handle what you need it to handle at a given voltage.

Hope it helps out over here

Superb - good find!! Pinned...

[Rockin]

Yeah nice find Gray, could have used this back in the days when i messed around with tecs

Beat you to it.

[Guest_Bloody_Sorcerer_*]

You're welcome :-P
be warned though: those amperage draw numbers are completely wrong... at least most of them. Some of them may have actually hit the mark, but all the low ones are totally off :-)
If any of you know the actual formula for amperage calculations, just holler.

[Gray_Mole]

Nice to see you over here

I knew the lowest range of values would be a ways off, but the ones closer to the ideal value are pretty close, close enough for most users to get an idea of what they'll need for a given setup, and that's a really big help!

Save a lot of 'I have a X cpu and it's supposed to put out Y wattage of heatload, which tec should I use?' type of questions, and this really answers it enough for most applications.

Most of the time, you'll just be running a 15v tec at 12v, or a 24v tec at 12v, so the numbers aren't far enough away to be of that much concern.

Thanks again, it's a good reference

to the forums BS

[Guest_Bloody_Sorcerer_*]

hehe, thanks guys. I'm contemplating getting a decent ammeter and any one of the pelts tested to see whereabouts the numbers stop making sense. when i finally get around to TECing my GPU I might do this :-)

[Guest_Bloody_Sorcerer_*]

well, since i failed to find the edit button, I guess i'm double-posting.
just wanted to let you know that after a couple of hard hours of work into the wee hours of the morning, I (with plenty of help) have fixed these charts up: here
just for the record... amperages were right, wattages were wrong! totally surprised me :-)
EDIT2: hey, theres the edit button... why did it go away on my other post? *shrug*

edit post button disappears after a little while (30 mins?)

Thanks for all the figures, if i ever get round to using tecs im sure this is gonna come in handy!

It is in fact 60 mins
