59C is on the warm side for a G3. A temperature in the 30s is what I would normally expect. Are you overclocking the CPU/cache by any chance? Yes, the internal thermometers can be inaccurate (more so with G4s than with G3s, but it does happen). The heatsink should be *fairly* cool given adequate circulation (that's it's job), but a common overheating problem is when the heatsink isn't making good contact with the CPU chip. Have you ever had the heatsink off? A bit of thermal grease between the chip and the heatsink can improve heat flow (if appropriate for your setup).
