now THIS is a TEC

Hooo-boy. Would a maze4 block (would have to get the coldplate and clamp), doublefan heatercore, and L20 be able to even keep it realistically working?

That thing is 62mm x 62mm or about 2.5" x 2.5". It will not fit on a maze 4 or any current block I have seen. Would be nearly impossible to properly implement it on a current socket of any kind. Would be better to use this as a inline chiller. :)

Also in their add I noticed they now have a 250/320 watt 50mm tech. That would be interesting.

You could fit in on Socket-A. Instead of using the mobo holes to directly bolt the block/tec/coldplate to the CPU, make a backplate with steel wires through the mobo holes.

Just need a block that could handle it. The problem is 2.5" is just about the max amount of room I have on any of my mobo's. You will still need at least another 1/4" on each side foru mounting of cold plate and sealing the block pushing the block to 3" which will not fit most boards. The tech is just to big. Would love to see someone try though. :evilaugh:

I've got 68 by 80 mm to work with, it would just barely fit amongst the caps. Damn, it sucks to poor!

Buy it, sent it to me and il 'try' ;)

I am just not sure it would be worth it. Would all that extra area actually get used? I wouldn't be a bit surpised ot see the 50mm 270/320 perform the same or better becasue of less wasted space. Well I got to many other problems to worry about TEC's right now. :D

That TEC would have 460W coming off the back from just itself at full power (assuming their 30A @ 15.4V fogure is accurate), you'd need some beefy cooling for that.

And just as important one hell of a power supply. Hope the power is cheap in your area. :D

we are selling a WCed 360W 60mm now, but not to the public
(psu too big, a Kepco 36V - 30A)

You would have to have a hellofa block to cool that.. several people have tried the 320W 50x50mm under a maze4 and swiftech and they get worse temps than the 226, because the blocks dont have the flow rates or cooling capacity to cool that much heat. It isint just the size of the block that matters.

I read somwhere b4 that TECs had a physical size limit due to fracturing from the stress of one side of the TEC expanding and the other side contracting when powered. Has some one found a way to avoid that?

Doubt it...
 

The issue you speak of doesn't necessarily instantly break the TEC, it just limits its number of thermal cycles in a lifetime. Take a 40mm peltier and this thing, and then power cycle them again and again. I bet the 40mm will keep doing that about four or five thousand (literally) more times after this monster cracks and breaks from the thermal cycling.

I imagine there is some size out there where it will break the first time, but it would be one big pelt. At half a kilowatt of juice, this thing seems big enough. The thing's big enough and powerful enough to move the heat off a small cooking hotplate! Pretty useless for CPU cooling, but its already been said: It would make for an awesome in-line chiller!

What's the current/performance curve on that thing like? Would be interesting to drive around 4 of them at 5V in a water-chiller. Should be easily doable with an ATX PSU.

62mm will fit onto a Socket A. It is in fact the absolute widest thing that you can fit between the mounting posts, so yeah, it'd fit - just. Use a 1/2" thick cold-plate, mill out a step for the cam-box, and probably make the cold-plate large enough so that the socket A mount posts went through it as well for added mounting stability.

'twould be a damn heavy bit of kit to be sitting atop a ~100mm^2 piece of silicon though. Would want it sitting flat, not side-ways.

Just got back from Fry's and saw that monster. Yeah that baby is big!

Cathar had an excellent idea on [H]: PWM-controller waterchiller attached to a hygrometer to maintain it so that its JUST too warm to condense, but colder than the water. I can build a PWM circuit fine but forget the hygrometer :p if I get some money Ill get that going.


also: these guys are in jersey, as am I. I want to find out where they are so I can check their stock out :D

replace "fan" with TEC and that should work, if I use higher-amp parts?

Holy crap but these things would've been handy while building my own chiller. You could make quite a beefy chiller out of four or eight of these things, and run 'em at 2-3V or so off a standard PC psu. I'm still tempted to get one just to play with.

Bill, would telling us a bit about any other "non-mainstream" TECs be a no-no? In fact, is there any way a nobody like me can find out about swiftech's industrial stuff? The info might've been handy while I was writing a paper for a thermo class a while back, and my interest is still piqued. (and I wanna drool over the pretty toys I can't afford, of course).

Yes, you'd need to replace T3 and maybe D1.

This one is more realistic:http://cgi.ebay.com/ws/eBayISAPI.dll...tem=3823905554

these peltiers arent as good as they seemed:
