Microcool Mosfet Chipsink




The Microcool heatsink has a white, soft thermal pad. Making good contact and adhering to the chip is always important. You don't want to hear the heatsinks drop off your card when you're gaming, now do you. The culprit, my X1800XT. Everyone knows the X1K series card's are pretty much the hottest running cards out there. Overclock them and they're unbelievable. For most people, the voltage regulation area of the card runs the hottest, or the mosfet area. This can cause instability, artifacting, or even pre-mature death of the card. Let's mount these heatsinks, shall we?


With one mounted to make sure it had good contact, I continued to mount the rest. It's very simple. Just take the heatsink, set it on the chip carefully, and apply pressure for a few seconds. With all of them on, it looks good! They're a bit un-even, but you don't see them anyway.


I oriented them a certain way to the airflow from my side fan would pass through them, making sure they get the job done right.


While I was at it, I decided to sink my vDimm mosfet, too. You can view before & after pictures above. Anyway, on to testing!!

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

When they get hot, they can cause voltage fluctuation which can make your computer unstable at a certain point.

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.
