I have an old Dell L500c uATX computer that I would like to silence. Its a socket 370 system running a Celeron 500. I found an Intel data sheet saying that the TDP for this chip is less than 25 watts. Cooling is currently accomplished by an aluminum based HSF. I'm looking into replacing this with a copper based passive solution. However, commercial solutions I've looked at thus far are aimed at higher end chips (1.5GHz+) and they're all active. So, I come to my question.

Do manufacturers typically give a power dissipations rating for HSFs with and without the fan? I'm wondering if a HSF designed to cool a much faster CPU might be able to passively cool my Celeron 500 were I to remove the fan. However, I have not been able to find any information on the total wattage dissipated by the cooling solutions I've looked into thus far. I've had a look around at some manufacturers' sites and come up with nothing.

Any help or advice would be appreciated.
