Hi, I am repairing an old Compaq Presario 6450NX with an MS-6577 motherboard with a Pentium 4 installed in a 478 socket.  However, the plastic heat sink retaining bracket that is screwed into the motherboard is broken.

 

I haven't replaced a heat sink before.  Can I buy essentially any Socket 478-compatible heat sink?  Is there anything else I need to take into consideration before buying one?

 

Thanks!  I appreciate you taking the time to look at and/or reply to such a basic question!

Here is your manual of the motherboard. If your plastic bracket broke you will need to purchase it separately. Here is one from Amazon. This is just an example. You may find one at another vendor.  Keep your fan but you will need to clean any thermal paste or pad off the heatsink and cpu using 91% alcohol. Purchase some good thermal paste and apply it to the top of the CPU. Only use a pea sized amount. Don't take out the CPU from the socket.

 

From this article you can see the thermal pad on the heat sink fan for the 478. If you have one of these and you intend to keep the fan then you must remove it and be sure the surface is clean before applying thermal compound.

 

If you purchase a new heatsink fan make sure you have the space if you use a third party companies heatsink fan instead of the standard intel heatsink fan.
