Can a heatsink replace a fan and motor in a computer so that a computer would run quietly and, if so, would it cause any harm to the computer? Thank you for your response. abx

Possibly - It would be safer to just a quiet fan! What CPU are you using? And what are you willing to do to get it to be quieter? Are you using your PC for anything specific (i.e. Home Theater PC)?

You could possibly have a "passive" [no fan] heatsink on the CPU but you would still need case fans to create air flow through the case.

This CPU Fan might be your best bet - at 16db, it will be very hard to hear.

If you have space, and absolutely don't want a fan, one of these might be your best bet. What CPU do you have?

Unless the CPU is a low-power device, it's not practical to cool it with passive heatsinking. A passive heatsink has to be enormous in comparison to a fan-cooled equivalent, and the few fanless computers that have been made were either cumbersome or prone to overheating.

Even the Thermaltake Sonic Tower isn't intended for a completely fanless system:

there needs to be at least an adjacent case fan to exhaust the hot air.

you could just try a quieter fan. Of course you could switch to liquid cooling, but depending on your setup that may be a bit excessive and expensive, and probably not worth it. :D
