    Default Fitting P4 3.0 GHz heatsink

    Just bought a new retail pack Northwood 3.0 GHz cpu complete with heat sink and fan. The chip sat in the socket well, and was clamped with the lever, but when I come to install the HS, the cam levers exert so much pressure on the cpu that the whole motherboard bends in the middle. Is this much pressure normal for this assembly? The HS is properly seated on the chip as far as I can see. The mobo is not in the box as yet, and I have taken off the pressure till I find out a bit more about this.

    Yes, that's normal. I would install the mobo first into the box, turn the box so it's lying down and then install the heatsink.

    its properly bending because the screws are not holding the motherboard to the case and holding it tight

    Nah its easier to put the heatsink on the mobo before u put the mobo in a case. It can be a bit fiddly if u put the mobo in the case, then try and put the HS/CPU on top.

    You reckon?? I always thought screwing a mobo in with a big heatsink already attached was always going to lead to more trouble than not.

    Nope dont think so. Usually the screws that need to be screwed to the case are nowhere near where u mount the CPU. Well the PC's I've assembled there haven't been any screw holes where u mount the CPU on the mobo.

    Just as long as you put the IO/back bracket in before u put the mobo in it'll fit, and screw up properly, no prob at all.

    Most screw holes are at both ends, and in the middle of the mobo.

    Well with P4's it can be a B**** to try and mount the HS/CPU/Fan AFTER u screw the mobo to the case. As you can get frustrated with the retention locks on the fan not locking onto the retention hole/s on the mobo.

    I always mount cpus on the motherboard before I mount the board in the case. I use a high density rubber pad underneath the motherboard for good support and to avoid damage.

    Yeah RAM and CPU/HSF on the M/B first if starting from scratch is usually the easiest way. But if you swap CPUs round (upgrade) while it's already in, then it's still pretty easy to do if it's already in the case. Personal preference
