I suffer from Asus Crosshair IV northbridge higher than normal temperatures. Now, what i wish to do is to have a pci slot fan in the slot directly underneath the northbridge so that it can cool off the heat sinks. All these fans, however, have molex connectors only, and i wish to plug the fans into my motherboard, so what i need is a 4-pin molex to motherboard fan adapter. Do these exist? And if so, where can i get one?
