75'C is too high.

Consider installing a bigger heat-sink. It could even be the thermal grease between the CPU and heatsink has lost some of it's effectiveness. I've seen this on old electronics I've pulled apart.

If you pull the CPU (and don't mind just tryin to clean/replace the heatsink compound), when you've cleaned up the cpu, check the part # on Intel's website and you can get the max running temp for that CPU.
