Fans and heatsinks will cool your system perfectly. If you were not overclocking, you could probably get by with only the heatsink and heatsink fan. I was just saying that they will never cool below room temperature because they are passive cooling. I guess that is just stating the unneccessary.

Overclocking will most likely void your waranty and possibly may damage your various computer components.

So to overclock. That would be running your cpu at a faster speed. For example if you have a 1000Mhz cpu and you run it at 1050Mhz, you overclocking it. The clock just increased by 50, hence overclocking. However when this happens, the cpu usually runs hottor. Therefore extra precautions must be made to cool it, such as a better heatsink, faster heatsink fan, and/or intake and outtake fans. The more it's overclocked, the hottor it gets and the more cooling you need.

There are 2 basic methods to overclocking: increasing the front side bus and changing the multiplier. For changing the fsb, all you do is increase the fsb, usually in 1Mhz or other small increments. The other way, changing the multiplier, is simply changing the multiplier. For example the 1000Mhz cpu in the exaple is running at a 100Mhz fsb and at a 10.0 multiplier. If you increase the multiplier to 10.5 but leave the bus the same, it will be running at 1050Mhz. If you leave the multiplier the same and change the fsb to 107Mhz, you have 1070Mhz. Sometimes when changing the multiplier you need to change the voltege to a higher voltege. To do overclocking, however, you will have to either change setting via jumpers or the bios. If you can do it in the bios, things are much easier. You're going to have to look at your motherboard manual to see how to change these settings.
