Cooling Fan and heatsink installation

[mightymo]

I'm in the process of building a new system using an ASUS A7V motherboard with an AMD 900 MHz cpu. I purchased a Cooler Master heatsink and fan (DP5-6H11) and I'm not sure whether -or-not I need to put some heat sink compund on the cpu and heatsink. There's a patch of phase change interface material on the bottom of the heatsink that's supposed to melt when it gets hot enough and fill the area between the CPU and heatsink. Is this good enough or should I add heat sink compound?

will you be o/clocking? if no, then the interface pad on its own should be adequate. you should be aware that removing the pad completely & using a high quality thermal paste like arctic silver will facilitate better heat transfer hence better cooling of the cpu chip, o/clocking or not!

At this time, I don't think I'll be over clocking. I'll try to scrape off the pad and use the heat sink compound you spoke of. Thanks for the reply and yes it was a double posting.

One last question. Should I spread the compound over the entire bottom of the heat sink or just on the center part of my CPU?

just apply a thin layer of the thermal paste to the slug of the cpu. clean the mating surfaces of both the cpu & heatsink thoroughly with some rubbing alcohol or acetone before you apply paste & assemble!
good luck

I assume the slug is the part in the center of the chip. If so, I've never heard it called that before.

yes,the elevated part of the cpu on which the hsf sits on!

Thanks again for your patience!
