I am running a X3 720be overclocked to about 3.5GHZ with the core voltage set at 1.47V. I trade futures and use this computer for about 8 hours a day running 4 monitors with charts always displayed and updated continuously with streaming data.

After the system reaches thermal stablility my core temperatures are as shown below according to SpeedFan

Core #1 = 45C
Core #2 = 44C
Core #3 = 42C

These are core temperatures with an ambient room temperature of 22C. Max room temperature could reach as high as 25C for about 3 hours in the hot summer months. So a delta of 3C can be added to those numbers.

Are these reasonable core temperatures to be running for good cpu reliability/life?

All opinions welcome.
