I have a AMD 1200 MHZ on a 266 Mhz bus. I have it clocked to 1266 mHz but it is hot 50-54 deg. C If I put it up to 1333 mHz it only goes up a couple degrees, it is stable but I don't want to fry it. It is one of those combo dealies and has a normal AMD heatsink. I was wonder what is a good one to get for around $30. I seen some that run from aorun 34 deg to 40 deg. Just some input would be nice.
