Well you should see improved temps on the CPU using the V6GT over the stock cooler.
However temps on the GPU will be
slightly better because the heated air from the Cpu will be expelled out of the case.
In order to get better temps on the GPU, you will need to disassemble the video card and redo the TIM on it. Of course good wire management along with good airflow thru the case will improve temps as well
Btw
