GPU max of 65C in 12 minutes of Furmark, memory junction maxed at 94C. In game testing GPU never went over 60C. My basement office stays probably 15C even in summer.

That's actually really good for temps.

If you wanted fans for your GPU, I'd suggest looking at GPU Cooler brackets like this one. Do note that the fans cannot be controlled via PWM. These are 2 pin fans daisy chained together on a 3 pin PWM connector.

They are also smaller lowish profile fans.
