I've kludged together a cooling solution for my UPS - one USB cable, one 8cm fan from an old unused computer (nominally 12V, but running it at 5V is fine), two short pieces of copper wire and a few fragments of power cable insulation to hold the wires in place against the 5V and GND pins (let's just say that shorting 5V with a data pin doesn't sound like a good idea to me). Leaving it pointed at one of my UPS's air vents, I get a reported 20?C drop in temperature; the front of the UPS case does indeed feel noticeably cooler. I don't recall if there's a fan in the F6C625-220V but if there is, it's clearly stopped working... (I do find it slightly curious that both "battery.temperature" and "ups.temperature" are always identical...) -- | Darren Salt | linux or ds at | nr.
