I have an old IBM Pentium III 500 machine with a CPU fan that sounds like it's about to die. I'm planning on getting a new computer soon, but would like to keep this one in working condition. It's a slot 1 P3 with a 50x50x10mm fan and I'm having trouble finding replacement fans at a cheap price. I don't need to replace the heatsink, so can I just get a socket a/370 cooler for $5-10, take the 50x50x20mm fan off the heatsink and use that with my existing heatsink? I'm not worried about the height difference as there seems to be enough clearance space. Also, my existing fan is wired to the motherboard with a 2-pin connector, but everything I'm finding has 3-pin connectors. Will I have a problem with this? Any advice would be appreciated.
