If the temp is still the same, then you need to check the fans. Make sure that they are running, and if they are, you need to check your CPU out. Take the fan and heatsink off and check to make sure that the heatsink is properly seated on the CPU and maybe check that there is thermal grease on it as well.
If you fan is running properly, then you need to check that out. Other wise, you need to invest in a good fan/heatsink. Also make sure that you have proper circulation through the case...maybe take your side panel off and see if the temperature drops some.
So check your fan out and let us know.
