XEON Heatsink/fan question

Hello all,

I'm going to build an Xeon PC and would like to know what the difference between an active / passive heatsink is, and whether I will still need to buy a fan using a passive heatsink.

If so, would the fan need to blow on the CPU or suck from the CPU. Also, the fans I've seen for socket 604 have heatsink included, can I remove the heatsink from the fan & just use the fan?

Bloody jobsworth procedures for a poxy fan!!!

I can't help you with your Xeon heatsink query but the difference between an active and a passive heatsink is that the active heatsink relies on a fan to keep it cool where as a passive heatsink does not.

These passive heatsinks are usually found on older processors which have slower clock speeds so they produce less heat and therefore they don't need a fan!

Thanks, that explains why the passive is more expensive. Maybe I'll see what the manual says when it arrives.

Thanks again.

fans usually blow air into the heatsink.

You can't use the fan without the heatsink.
