I ordered the 50mm one from pTS. I found the konform coating from some Vance Baldwin place here in Florida. and ordered some neoprene from PTS as well as dielectric grease.
Should be ready to do some serious cooling here soon.
I only plan on running the TEC at 12V (rated for 24V@26A) - So Im not looking for sub zero temps. Just enough to keep me stable at 2.8-3.0Ghz.
I still have my RAM to upgrade, so I've got another month before it all comes together. *shrug* It would be nice to see some negative C temps though.
