Many heatsink and fan kits are compatible with both Intel and AMD sockets. Check the specifications carefully, though.
You can replace an Intel Core Duo Processor by first removing the heatsink and/or fan from the processor and removing the old thermal paste. Apply thermal paste to the new Intel Core Duo Processor and reseat the heatsink and/or fan.
No, this is a processor designed for laptop computers, so the heatsink and fan will have to be specific to your laptop. You can reuse the current equipment.
The optimal fan speed depends on the size of the heatsink and the clock rate of your processor. As such, there is no single answer.
It depends... Look up the heatsink in question to determine compatibility. It may require a new set of mounting hardware, but most heatsink manufacturers try to maximize compatibility.
A heatsink and fan is required. Without at least a heatsink, the processor would get way too hot in a very short period of time. This overheating of the processor could permanently damage it and render it useless.
fan and heatsink
If you buy a retail boxed processor, yes. You do get a heatsink fan (HSF) with the processor.
The fan speed is really dependent on the size of the heatsink. A large heatsink can use a slower fan, while a smaller one will need a much faster fan.
There is a certain operating range for each type of processor. As long as you install the proper heatsink and fan, your processor should never overheat. If you plan to overclock your processor, (make it work faster than it's really intended to) then you need to take the necessary steps to keep it cool. Such steps can include adding a bigger heatsink, a faster fan, and/or adding liquid cooled hoses to it.
It is fairly cheap to buy. When installed with HD graphics card, it is very fast on both Windows 7 64-bit OS. Very silent fan heatsink - well worth the money.
The Cooler Master Hyper 212 Plus is a very high performance cooler which i have used many times in overclocking both amd and Intel chips. and for a price of around $30 you cant beat it. Just be sure that your case has sufficient room because this heatsink/fan is about 6-7 inches tall. (works for Intel sockets 1155, 1156 1366, and amd sockets am2, am3)
There's no real answer to this question. The purpose of thermal paste is to fill in microscopic gaps between the processor die and the heatsink. This allows better heat transfer to the heatsink, where it can then dissipate. Depending on factors like the architecture and speed of the processor, the size of the heatsink, and the speed of the fan, it is quite possible to run the processor without any thermal paste indefinitely, though the temperatures will likely be higher.
