My E7500 at stock speeds will max at 76C, I might suggest upgrading to the Zalman 9XXX series copper heatsinks.

or just dust out your system and ensure that there is adequate air flow through the case. The main issue here is that you added a new GPU to the system, which I'm assuming runs hotter than the old GPU, so you've introduced a new heat source in the case, and if you don't have adequate ventilation, you've created more problems for other components (namely, the CPU) in the system.
