-=PCTechTalk=- Re: heatsink and fan

Hi
It is important that you get a heatsink and fan to fit the receptacle and
CPU of the mother board. The newer and faster CPU's generate more heat than
older ones (depending on how old of course). The heat sink can be made from
many materials. I think you will find copper ones to be the best and most
expensive. ( a decent heatsink and fan is relative cheap to the cost of
replacing a bad CPU due to heat failure) Let me state at this time, that the
heat taken from the CPU is distributed into the case. With out adequate case
fans to take the heated air out of the case into the room, a good heatsink
and CPU fan can only achieve a limited amount. The paste that was
recommended is designed to transfer the heat produced by the CPU to the
heatsink quicker. Therefore I suggest you also consider the number and size
of fans in the case. My case has two fans in the power supply plus three
(box) fans in the case plus a smaller fan on top of the CPU heatsink. (Two
of the box fans pull the air in from the front and one box fan takes the air
out of the case into the room. The two fans that pull the air in from the
front have two HD's (120 and 40 Megs) sitting behind them and therefore cool
off the HD's. All three of these box fans are about 3 inches square and
black in color. One of the power supply fans pulls air up from the case into
it and the other fan  move the air out into the room. )

Another thought here, if you use a heatsink that is not designed to fit on
top of your CPU, that may void the warrantee on the CPU. Some CPU
manufactures will/have require you to send the heatsink in with the damaged
CPU.

I would also suggest (depending on the size of the HD and its speed) that
you consider getting a fan that attaches to the bottom of the HD to keep it
cooler.

Also consider the way the ribbon cables in the case are arranged. Will they
restrict the air flow severely, moderately or hardly at all? Some people
overlook this and it can be an important factor.

Please keep in mind that every component in the case produces heat. So the
quicker you get the heat out of the case the better for your computer.

Hope this helps.

Life is what happens in between plans.
