Solve : how tight should the cpu fan be??

Answer»

i had just changed out a cpu and noticed the heatsink  fan is not fully in contact with the cpu.  I believe the fan is SUPPOSED to be right on the PROCESSOR to work correctly. my old cpu(pentium 4) heatsink screwed into the motherboard.  I don't think the push bolts on the new cpu(CORE 2 duo) heatsink are going to work with my board.  Could I possibly use the pentium 4 heatsink? It has the same size fan but has a larger HEAVIER metal heat sink section and it has a what I would call a breather plactic cone that links it to the vents on the chassis. Quote

Which one is it ? ?the processor is a core 2 duo e4700, the motherboard is a intel d945gclthe pentium 4 fan is a cooler master cm-12v, the fan that came with the core 2 duo is a dtc-aat01 12vdc.  there are also some other numbers on the intel fan---e18764-001,dp824130.Ok I figured it out, there is a plate on the backside of the main board I had to remove so that the new fan would SEAL.
