Question I have a GTX 660 2gb running at 56% and heats up to 78°C - - - is that too hot and what should I do ?

[Ilzamgamer]

It doesn't even use 99% of the card but heats up when gaming at ultra(NFS rivals) should I adjust the fan curve or is it dust or thermal paste issues?(I don't know much about this stuff and can't re apply thermal paste by myself since I've broken one before)

are you playing a graphically demanding game when it heats up to 78 C ?

NFS rivals at ultra settings

that looks like normal temp on ultra gaming. A 660 is a good gpu for NFS rivals.

does your case have good airflow?

and may I know what are the gpu temps on idle?

My case has a Fan in the side which blows air directly to the GPU, and CPU my CPU doesn't pass 60°C but I have no exhaust fan should I add one on the rear. (there is no other place for extra fans only these two)

would be helpful if you could post a pic of the inside of your case. So better advice could be given.
