So the wires for the fan come wrapped around the heatsink. Should I unwrap them before using this beast? Right now they appear to be held to the heatsink with black clips on each side. I wasn't sure if they are supposed to stay wrapped up like this, or if they need to be unwrapped? I also noticed that quite a bit of force was required to close the lever to lock the cpu in place, is this normal with the socket 775?
