I needed one so i build my own. -2 x 40mmfan -1 Antec 900 front bay cover. -1 x thermal sensor with LED reading and 2 diodes. I had a few extra front covers laying around + a couple 40mm fans and a thermal sensor salvaged from my Antec hd cooler. It contains 2 diodes and 2 fan connectors so it's really a neat thing I taped the inside of the cover with some foam tape so the fans would stay in place. Mounted the fans and the thermal sensor. Once i connected them i tried to keep the wires as far in as possible, So they would not touch the ram. Going to fix this when i get the new fans. Then i will shorten and solder them. I bend the sides of the cover so i can click them over the edge of the ram. So it it will stay in place. Pretty simple really. Took me about a hour to make this.
