anyone ever hear of em or use them?. my dad said he use to use them back in the day for overclocking. by adding them to the bottom of a cpu heat sink and then thermal pasting it to the cpu.. im just wondering if the same thing could apply to cobs. they seem to act like a cpu in so many ways.

comes up once in awhile. good for moving heat at high temp differentials but not all that efficient so a loss for our purposes

Yep. Uses more power than the cob to cook a cob so you're better off with 2cobs and 2x the light as opposed to one cold cob with a 10% increase in output.

Also TEC is very inefficient at higher temps so with out water cooling the delta will be shit

Yup biggest issue is condensation on the cooling side. Deal with that and it's doable... But I would Watercool to keep the heat out of the room for sure. I would recommend passing unless you're trying to run them way over operating temp for some reason

what about adding one to a heatsink? would it make any major difference?

If you had "blank" watts of cobs on a heatsink you'd need at least "blank" plus 50 watts to the peltier alone to have effect and the heatsink would need the "blank" + "blank" plus 50 watts of dissipation. So....200w of cobs would need at least 250 watts of pelt which is a total of 450w and the heatsink would have to handle the 450w..... completely not worth it.

fuckit then im gonna use a water fountain pump in a 5 gal bucket. a pc water cooling block and have a heater core stuck outside in the snow for the rad.

Water cooling is the most effective way to cool, but requires more safeties to be built in. If the pump fails there should be a over temp protection. I know from experience:wall: $350 worth of parts because I didn't have everything on one plug and no thermal protection.

They use ALOT of power.
However, watercooling COBS would work very well.
I use one of the 2 x large Thermometric Coolers and water blocks + Audruino to have a custom Chiller with precise temps
in my RDWC/Fogponics.
I would imagine running water block to COBS would work well.
