I put an 80 watt TEC on an mmx233 and im cooling the TEC with some pretty good aircooling (since it is only 80 watts) and i read up on calculating temps of the cold side of the TEC, but it is all way beyond me :confused:
The mmx233 produces 23 watts i think, what would the approx cold side temp of the TEC be?
thanks!

15c +/-20c

Insulate that card:)

This should work pretty good, should go quite a few *c below ambient... insulation recomended.

Its important to use a good heatsink with a big fan on it for the best temps, your going to be cooling a 120watt heat load (approx)

Alright guys, i managed to get the peltier setup working :D
My aim was originally to get top spot on the orb for a pentium 1, but now i just want to max this system out :banana:

The mmx233 goes to 300 (2.5x120) and highest bootable fsb is when im running at 270 (2x135) but memtest isnt stable :mad:

The original setup

80w TEC on the cpu and a 30w TEC on the NB

285mb/sec OMG sdram does wonders for socket 7 :rolleyes:
(not stable)

Thanks for the advice guys!

I think memory and chipset will be the limitng factors.

Can you do a chipset Vmod (or boost 3.3v line) ?

i should find a second Aopen AP5T-3.1 and have some races with you lol :D

be limited to PCI vid cards though.. :/

Yeah its very fun to try and max out a board that isnt expensive :D
One problem i have though, the peltier on the NB is just sitting loosly on top of the NB, which doesnt have any mounting holes at all... what woud you guys suggest i use to mount the NB TEC and hsf onto it?
oh yeah.. the chipset voltage was raised form 3.3v to 3.58v but i can raise it further with a voltmod.. what would the max voltage be that i should do?
mainly because i dont want to lose my stick of sdram that does more than 155 @ 2-2-2 :p:
