Microcool Mosfet Chipsink



What is a mosfet? A mosfet is a small transistor that handles current flow between drain and source. There are hundreds of mosfets in your computer, handling the voltages that go to your CPU, RAM, etc etc. When you overclock or overvolt anything, mosfets tend to get hotter because of a higher power load. When they get hot, they can cause voltage fluctuation which can make your computer unstable at a certain point. At the least, it can hinder your overclockability. To keep your mosfets cool, Microcool came out with their mosfet heatsink.


The Microcool heatsinks come in a small clear baggie. Let's take a closer look at these babies, shall we?

A Closer Look


When you take them out of the little baggie, you'll first notice the height of these things. They're quite tall, so be careful when purchasing them as they might interfere with other components. They each have 9 fins, for dissipating heat quickly and efficiently. On the bottom you'll notice they come pre-applied with a thermal adhesive. Just peel off the transparent blue backing and stick it on the component of your choice. This is fine for most users, but some may feel the need to use an aftermarket solution, such as Arctic Silver Adhesive.

They perform great, suprisingly. You can read the review here.

the warmer mosfets gets the less power can flow through them so im not so sure the voltage starts to fluctuate but more gets lower but can be wrong.Quote

Yeh, I read wikipedia's (i think) definition and paraphrased it.
