Firstly, how many programs do you have running in the background??? close down any and all the ones you don't need at the present moment. Having stuff running, 'for quicker starting' usually saves about 1 second - if that.
Next, have you ever cleaned inside your PC??? If the case hasn't been opened in the last 6-9 months or so, it's fairly likely to be a dust-bunny creche.
Using a tin of compressed air and an artists paint brush - about 1/2" wide and fairly stiff, carefully brush 'n' blow the dust out. Pay particular attention to the CPU heatsink, the vanes are the favourite haunt for dust-bunnies. Using a drinking-straw or equivalent to hold the fan blades, brush as much dust off the blades, too.
That lot should bring your CPU temperature down by quite a bit
