Is anyone out there happy with their o/c PIII and peltier? If so, can you please post what speed your CPU is at, what core voltage, what temperature (no rain or cpuidle or anything like that) and which peltier you are using. I have tried one 50W peltier and it didn't do jack for me (only lower my cpu temps by 3 c, 5 c on a good day.) I am considering maybe trying another peltier before :
A) I try water cooling
B) move my system to the garage (outside temperature sub zero)
ok, P3 450 at 675
cpu=sl37c week 33 malay
Level 2 = nec 3.6N's
Voltage=2.1
Mobo = asus p3b-f
Cooling= 1 120mm bottom front intake
1 120mm drawing out/ ( side of case next to alpha)
1 80mm blowing on memory ( memory = corsair 133 128meg )
2 power supplys ( 300 watt each, 1 for peltier only )drawing out.
( inwin q500a tower )
1 tennmax lasagna cooler ( in replacement of the bx heatsink )
1 tennmax cooler on my g400
1 alpha p3 heatsink, drawing air off
1 peltier, ice71 from www.tetech.com ( potted ) 77 watts.
1 1 1/2" x 4" x 3/16" copper cold plate.
Craft foam and meat packing for insulation, ( no condensation)
thats about it,
Temps = Mobo=71 to 73 f
room temp= thermostat on 69.. ( Puters 5 foot from the thermostat )
cpu temp taken from internal diode, from mobo monitor, and asus probe utility,=33to 39 farenheit. Runnin Quake 3, 3dmark99, or final reality, cpu temp never goes over 48f. Hope this helps
Hey, big Lar, can you tell me how you set up your second power supply? Is it a AT or ATX? Cuz I am not sure how I can power on a ATX power supply with no mobo, and can I just turn on the power switch on for a AT? One more thing, can you tell me how much amp is your power supply rated at? I was thinking about picking up a Frost-74 from Te Tech too.
Hi Niteowl... ok/ I use 2 300 watt ps. My pcpowerncooling 1 is rated at 12amps at 12v, I use this 1 for my peripherals, computer... The other is at 9amps at 12v,This is running the peltier only , and of course the ps fan...I hooked mine up on a 30 amp 12v switch I got from radioshack. Both are atx, and in my schematic for the pcpower supply it shows the 2 wires that turn the mobo on , ie; the wires in atx connector. They are, no my mobo,the third and fourth wires from the top on the same side.which side it was, it didnt say/ lol so i just experimented with the peltier, and a fan, until i got it right/ then taped into the wires with scotchlock connectors/ also from radioshack.color of my wires are green and black. YOURS MAY NOT BE THE SAME... CHECK YOUR POWER SUPPLY LITERATURE!!! Hope this helps
Thanks for the info, big Lar. I think all ATX p/s should have the same wire configurations (or else there would be no standard and the mobo would all be fried). I just gotta figure out which orientation it is. And I will be careful.
