Peltier Cooling... need help

[pleclair]

Once upon a time, when processor weren't locked and stuff, (back in 166mmx days) I bought the best cooler at the time, from computernerd, the peltier cooler with the monster heatsink and fan. 70$. I still have the peltier unit tho, the heatsink and fan have been already used for something else and aren't available anymore.

So here I am, I got the peltier unit, i put it under the retail p3600e heatsink/fan, but is it possible that this heatsink/fan combo isn't strong enough to dissipate the heat generated by the peltier? I can't even boot in windows that my alarm sensor beeps already. And no need to say that the heatsink is real hot. But why? I thought that this heatsink what enough, since heatsink have changed since 3 years....

And i noticed one thing. When i tried the peltier, i had no choice but to remove the heat paste. When i put it back normal with just the heatsink and fan, the alarm sensor beeped again, i had to put back some paste to make it work. This tiny processor seem to generate an incredible amount of heat. To me it seems that it really doesn't compare with any processor i tried. Anyone tried a p3 without cooling.. within seconds it's red hot. While any other processor i tried, i often installed windows without having plugged the fan... Anyway...

I'm now at 800mhz from 600... not that bad, but would have liked to go further with peltier cooling... well, maybe later http://www.sysopt.com/forum/smile.gif

OK, step 1...
Pick up an Alpha P3-125 Kit and 2 60mm fan grills from www.2cooltek.com (http://www.2cooltek.com)

Step 2:
Get some alluminum oxide in the tub from the same place.

Step 3:
Get some Ultra Black. Discount Auto Parts usualy has it.

Step 4:
Get item #64-3010A and #643017A from radio shack (some screws and some nuts)

Step 5:
Find out what side of the TEC unit is hot and what is cold. Set up the CPU will normal cooling for now, no tec. Plug in the unit to the system by itself, boot up, and turn of the system once it is in bios, you will be able to tell what side is hot and what side it cold, make a small mark with pen on the edge of the cold side.

Step 6:
Pull the back off the PCB.

Step 7:
Put some of the thermal stuff on the CPU core using a toothpick or knife blade, do not use your fingers, make the blob in the middle of the core, tall, but not covering the core.

Step 8:
Put a blob in the center of the heatsink a bit bigger than the one you put on the core and press the TEC units hot side to the center of the heatsink. Press it as hard as you can.

Step 9:
surround the pressed down TEC unit will ultra black (around the edges only, the face should be visable) and let it dry for at least 4 hours, prefferably with 4 quarters sitting in the TEC unit and a text book sitting on them.

Step 10:
Find the four longest screws in the pack and run nuts to their heads, making the heads bigger.

Step 11:
Once the ultra black it dry, remove the book and quarters, put a perimiter of ultra black around the edges of the TEC, like about 1/4 of an inch tall and wide.

Step 12:
Press down the CPU so the core is in the center of the TEC unit. Press it down hard from the back of the center of the core.

Step 13:
Follow the instructions for putting on the backplate and screws for the alpha like the instructions say, except the back will be removed, and you will use those long screws you put together. Make sure the screws are as tight as possible, if you screw them all the way in that they will go, and the PCB is not bent a little, pull them out and add a second nut to the screws. You want the PCB bent a little.

Step 14:
Let is sit for at least 24 hours, preferably about 36 before installing it in the system, the ultra black has to cure 100%, and the thermal stuff will settle a little.

These steps will make your CPU last a lot longer, and overclock a lot more. if you notice frost forming on the back of the PCB, turn of the system as quickly as possible and cover the back in iltra black, everything except for the contacts that go into the slot 1 connector, you will have to spread it with your finger, and make it thick, at least 2mm, that will make your CPU even colder!
