Hey mrjodecast,
1) Yeah auto fan control doesn't do too much, just keep the fan speed at the lowest setting and turn on auto, it will slowly increase the fan speed by itself.
2) on a GTX 960, usually +150-200Mhz on the Boost Clock, I'd go with
+150mhz -200Mhz on Gpu clock, it will change accordingly for the core and boost clock
+400-500Mhz on the Memory clock
Changing power limiter to 108% or whatever the highest value is
and +100mv on the Voltage.
Now your milage will vary for sure, so find with tweaking the right value, and make sure the GPU is stable. If it isn't then dial the clock a little bit back to the original stable position and continue again. Take it slow
A safe clock speed is +150Mhz but I'd try to go for 175Mhz
and a safe memory clock speed is +400Mhz, but again go for higher.
You need to change the power limiter and voltage for sure though for this.
