Hi all,
Since I got the GTX 780 I noticed a big increase in temperature inside the case which affected the CPU temperature also (moved from 70C MSI R9 380 to 84C Gigabyte GTX 780), I managed to change the airflow to guarantee fresh air to the CPU and GPU by exhausting from top instead of the back and CPU intake from the back instead of inside case, GPU intake from side and front instead only from front (which can be affected by cables and HDD cage)
Note: Ambient temperature is around 28C indoor in summer (big room without AC)
Even after these changes the GPU was still hitting his thermal throttle point at 84C with 70% fan while stress testing and also experiencing random driver crashes in some games, I did down-clock it for 105mhz of the core and 200mhz of memory which solved the driver crash issue but thermals were the same because of GPU Boost (if I'm not mistaken)
I had some thermalpaste left which came with the Hyper212 Evo so I decided to renew the GPU paste, I removed 7 screws and with some wiggle the cooler was removed, I unplugged the fan and cleaned the old paste, applied the new paste (used line method because the surface was bigger than lga115X processors) and assembled it.
After the new thermalpaste was applied (and it is not a top class paste, just a good one) the new thermals with same down-clock are 79C at 65% fan speed, 5 degrees with 5% less fan speed, I call that a success in the very hot summer time
Note: I didn't take pictures for the whole process, only for the disassembled card, also this method is effective if you have 2+ years old card (usage time) because thermalpaste applied by the companies starts to degrade after this period (read that on tomshardware forums)
