so, in english, the answer to your question is yes. they are easy to replace, just don't stab your motherboard with a screwdriver or get thermal paste anywhere on the processor but its core (the lil black square in the center of the processor). If you do get thermal paste on the rest of the processor, it won't come off without rubbing alcohol, but it does come off easily and completely.

you can get a heatsink/fan combo for your speed processor at around 20-30 dollars. buying just the fan won't help much cause no-one sells cpu fans without heatsinks, and even if they did it probably wouldn't fit.

removing the heatsink usually involves prying the metal clips of the heatsink off of the plastic hooks of the motherboard that hold the heatsink onto the processor. most good fan/heatsink combos manufacturers realize thsi is annoying and have a lil space where you can wedge a flathead screwdriver in to add the required pressure, whether you're attaching or removing the accessory.
