I can only speak from experience here. On my original Beige G3 266 I
actually ran it without a heatsink for a bit (about 30 minutes under a light
load) after overclocking it to 300MHz. Temps were just under what's
considered safe for the chip and I had to disable the backside cache to get
it to run stable. With my current 400MHz chip overclocked to 466MHz I not
only need my heatsink but I also have to have a fan on top of the heatsink.
Without the fan the backside cache overheats and causes crashes. This could
again be related to overclocking the CPU and backside cache.
