I am thinking of cooling my Geforce2 ddr GPU with an aircooled peltier. What wattage peltier do you guys recommend? I don't know what heatsink I will use but I don't want to spend a lot on it. Maybe I'll get another Golden Gate and slap it on.

Well I'm not certain how much heat a Geforce 2 kicks out. But I would go with a 56w or 72w tec. then use maybe a socket 370 Alpha or something and rig it all up. That should be able to get rid of the heat. Although one thing to remember is you will be dumping a lot of heat out into the case. But I'm sure you know that already. If you have good airflow in your case it should'nt be a problem.

I have decent air flow in my case so I'm not concerned. I think an aircooled peltier makes a lot more sense than just water cooling. I have been pondering the voltage hack for my Geforce2 ddr, thats why I'm interested in a chilly GPU. Anyone know where I can pick up a very inexpensive peltier?

you can get a 72 watt tec from becooling.safeshopper.com for $15.00. it comes with a power connector, but the tec is not potted(waterproof). dangerden has a 80 watt tec that is potted but its $24.00.
what size psu do you have? you can get away with using your computers psu if its 300 watts+ to run one tec this size. you wont get the best performance, but it will still work rather well.
also make sure to insulate gpu (front and back) so no air can get in there or else you will get condenstaion, and thats not good.
you can find some great info on this web site under peltiers, also procooling.com(look at the pelt fourm), and tedist.com have lots of info.
hope this helps.

I have an 85w tec w\ copper cold plate from Tom Leufkens I'll sell you for $20.00 shipped. I used to run it with a P3125 Alpha so I know it can be aircooled. Besides if your only running it at 12v's, You'll only be getting around 77% usage of the tec which would run right around 65w's or so. That should be fine.

It's potted and very reliable. Let me know if your interested?

It's a deal if you accept Paypal. I'll try running it off my psu if I can. If not I'm sure I can dig up another power source.

I used a 72W pelt on my old GF2, I've now got it on my GF3. if I was building it today i would go for a 85W, those Geforce chips kick off a lot of heat.
Air cooling would be OK if you use a good heatsink, biggest problem will be that you will block off 3 or even 4 PCI slots. I use water-cooling and only block 1 PCI
