I recently bought a RETAIL PIII-600. Within 2 months the fan that came with it stopped running, and I dare not run the processor without proper cooling. This SECC package is of the type where the circuit board and chip are exposed, and the retail Intel heatsink sits on top in direct contact with the chip. All of the heatsink/fan combos that I can find in stores here are for the older PII package where the circuit board is covered by the metal plate, to which the heatsink clips on. I HAVE to find a fan/heatsink that will replace the ones that originally came with my retail PIII-600, and I am hoping that somone here can help me. If anyone knows where I can find such an item, or even what that form of the SECC package those retail PIIIs are, please let me know.
