Is it smart to run a fanless heatsink?

[Asnrefugee]

I'm running a 2.53 ghz 533mhz fsb. 1gb of ram.
My heatsink fan is pretty loud right now. It's an oem intel fan. I was wondering if it was smart to run a fanless heatsink for a little bit?
Also anyoen know of any good quiet heatsinks/fans.
478 socket.

It's OK as long as you are looking at burning the chip up. :Q

The newer chips require a heatsink and fan, otherwise the temperatures get out of control. A bare heatsink without sufficient air pulling air away or blowing air over it just ain't enough.

it is possible if you run the cpu at a lowe enough clockspeed... and reduce the voltage as much as possible...

but at stock speed, i wouldn't try to run it w/o a fan...

At that stock speed, no. The P4 will clock itself down to very slow speed to reduce the heat-output and be pretty much unusable. You would need a much more complex setup to be able to run so fast a cpu fanless, the Zalman heatpipe case for example (Google for it) or some kind of watercooling (which would then require a pump and a large radiator/heatercore as it would need a larger area to radiate heat when not removed actively by a fan).

You could underclock the cpu heavily and the current sink MIGHT work but have very high temps like mentioned above though.

The best, most viable solution would be getting a better heatsink with a lownoise fan, the Zalman CNPS7000 series for example (running it at 20db should be plenty for that cpu).
