Doom3 “ultra-mode” bloodcooling case mod

Fortunately, gamers have found a heat-sink capable of handling the load: The human body.
To perform the mod, connect an intravenous catheter to the water block of your video adapter’s chipset cooler (be sure to completely drain the coolant). Don’t worry about connecting the water pump—your heart will do the pumping. You’ll draw in heated blood from the chipset and provide cooled body temperature blood to it. The heated blood causes an increase in body temperature (feels like a fever) that causes profuse sweating, which subsequently lowers body temperature. Essentially, your entire body is turned into a heat sink for the video processor. Use a hurricane fan to cool your body or play in an air-conditioned room, and drink plenty of fluids.
Players average a body temperature of about 102 degrees while playing. It’s especially important to monitor body temperature closely however, as temperatures above 103F for extended periods can cause brain damage, and there have been reports of players becoming comatose or entering into a zombie-like state due to heat stroke.
