I have a foxconn mobo with a P4 3.0 lga775. I bought a better heatsink and fan rather than use the stock intel. The computer runs very well with an avg temp between 46 and 56. I noticed part of the heat sink on the side facing the rear would not screw down as far as the right side because it was touching something on the mobo. I've looked at it very carefully to make sure all was tight. You have to look close to see this. With this in mind and everything running well is it any cause for alarm?
