    It could be a number of things. Without more information it can be difficult to gauge what is causing this. What were the old temperatures and what are the new temperatures?

    Of the various things it could be:
    1. Didn't properly clean off the cpu prior to installing new heatsink.
    2. Used too much thermal paste.
    3. Used too little thermal paste.
    4. Used thermal paste when a thermal pad was already affixed to the heatsink.
    5. Current airflow in system does not allow air to get to the fan for the heatsink.
    6. Heatsink not seated properly.

    I guess my first suggestion would be to remove the heatsink and make sure everything is fully cleaned, and then reapply thermal paste and try again.

    Good Luck

    Provide a link to the cooler you used. It sounds like you have an airgap between the heatsink and the the processor heatspreader.

    An air gap is going to be somewhere between the Processor and the heatsink. With the heatsink inplace you would not see it.

    The installation instructions for that cooler are poor.

    When you get the new thermal compound clean the bottom of the heatsink and the heatspreader and make sure it is prefectly clean. Put a drop of AS5 about the size of a pea right in the middle of the heatspreader, make sure the locking pins are in the lock position, align the locking pins with the holes in the motherboard and push down on two pins at a time diagonal from each other. After those pins are down and locked push down on the other two pins at the same time diagonal from each other. After all 4 pins are down and locked, go back around and push down "firmly" on each pin cap one at a time.

    If you are more comfortable pushing one pin at a time that's OK, just make sure you hold the cooler so the other pins stay aligned with the motherboard holes. Either pushing one pin at a time, or two at a tiime diagonal from each other works equally well. The advantage to pushing two at a time is that it keeps the pins aligned better with the holes in the board.

    I recall a couple of other people having problems with that cooler because the bottom was not machined smooth and they couldn't get a firm contact between the heatsink and the heatspreader.

    If you reinstall the cooler and the temperatures are still high lift the cooler off carefully and take some pictures of both the bottom of the heatsink and the top of the heatspreader and post them so we can see what the "footprint" looks like.

    You can install the thermal compound as AS5 instructs, but I always just use a pea size drop in the middle of the heatspreader. When the heatsink locks down to the motherboard you should get all the compound spreading you need, but if you are more comfortable using the AS5 instructions thats fine also.
