JadeGames :
I have a 750D from corsair. It is the airflow edition. I Think its pretty good airflow.
I just looked up a review of your GPU from AnandTech
shown here. That GPU runs very hot. In their testing they hit 84C with Crysis 3.
I've had three of Nvidia's reference blower design GPUs, and they run several degrees warmer than say the multi-open fan designs of vendors. For example, my original EVGA GTX 970 with a blower ran at 66C but another with EVGA's new ACX 2.0+ design ran at 60C when under load with 85% fan speed (I use headphones so noise is no concern).
This is one reason why I asked what case you have. Blower design GPUs are best for cases that have limited air flow as the hot air blows out the card itself. External fan-type coolers like EVGA's ACX do not blow the hot air out the back directly through a closed duct like the blower design but instead rely on good internal case airflow management to move it out.
