My Dell T5500 is running pretty hot in a room with no A/C and two video cards installed, so I'm looking for ways to keep it cool. There are two empty 80mm fan bays on the rear of the case, but no obvious way to provide power. There is a custom 5-pin Dell header near the drive bays, but I'd need a proprietary fan with a really long cable. Oddly, though, there is an internal USB port (not header, a full port) near the rear of the case.
I've seen fans with USB connectors on eBay, but I'm doubtful that 500 milliamperes will provide much airflow. Any advice?
