I got an old bucket and lined it with tin foil to reflect the heat.

I have a bucket lined with tin foil facing the back of a computer that is currently producing Vanity Bitcoin Addresses to help with fund raising of various projects. Inside the buck goes a bottle of water with a thermometer on it so that I can measure the temperature.

I am monitoring the power consumption as I go.

VanityGen UI comiled from Xcode on OSX

Temperature gets up to about 37 degrees celsius. With an amient room temperature of about 25 degrees.
