Microcool Mosfet Chipsink

Introduction

Introduction

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.

Packaging





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.

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.

that's made from alumunium right? if that's made from copper,is better i think.. (cause cooper 3x alumunium in heat spreading i think)

depends on.

aluminium is better than copper to transfer heat to the air so with a low airflow aluminium is better.

you can se the same thing in reviews on the zalman 7000b.

at the lowest fan setting the alcu performs the same as the cu but at max fan settings the cu is roughly 2 celsius better.Quote

Yep and 'fets get low-flow usually so these will be pretty effectiveQuote
