I need to get a pci cooling fan that does not require a connection to the power supply.
I bought one from amazon .uk recently, they have a good selection of various prices. They just slot straight in , no power cables needed. amazon .uk/s/refnb_ss_w_h_
yeh there are number of fans which has sort of connectors which fits directly on the motherboard. you can have one
I've never seen one. If you're out of fan connectors, then you can use a fan with a molex connector. If you're out of of molex connectors, get a molex splitter. You just won't be able to monitor the fan speed unless you get a fan controller.
