In home-built computers, aftermarket CPU Cooling is usually a requirement. Usually the fan and heatsink are replaced to help keep the system from overheating.
When you go to add a CPU Fan and heatsink, you will have to consider a few things.
1. Do you want liquid cooling, or air cooling?
Air is a lot cheaper than liquid cooling, but liquid cooling can be fun to setup, and running fanless (with no noise) is great.
2. What size is your CPU?
You need to know what size your CPU is. If you don’t know the size I recommend you read the following post:
3. How big is your case?
Is there lots of room, usually this isn’t an issue, but after looking at the ThermalTake Big Typhoon system, I figured its worth mentioning.
4. How big is your budget?
If you want liquid cooling, and your budget is less than $100, forget it. If you want air cooling, and your budget is $500-$600, you’re going to be in a nice surpirise when you see the most expensive fans are usually priced under $75. If your budget is $500-$600 and you want to have some fun, that budget should get you a pretty decent water cooling setup.
With that said, you should write down your answers to the above questions, and bring them to a tech store. With the information provided above, they should be able to point you in the right direction.
