The difference probably is that the core2 fan is using pwm to run the
fan at 1000RPM or slower when the cpu is cool while the fan on the
5400+ runs at full RPM all the time. There are two options to fix
1) Replace the fan with a slower case fan that has as much CFM as the
fan you replace. Generally this means get a taller fan.
2) Replace the heatsink/fan with a descent replacement. Thermaltake
silent and AC Freezer pro fans are good and cheap.
