The GTX 650’s GPU has a TDP of 65W and it doesn’t get very hot. The large heatsink and a 9cm fan did well, both in performance and noise departments. The card didn’t exceed 60°C until our overclock, and even then it did so by 2°C. The fan goes up to 32 percent RPM in AUTO mode and it will stay quiet throughout.
Long story short, Kepler based offerings are better in power management than Fermi. Luckily, the GTX 650 Ultra Charged is here to save the GTX 650’s face, because the GTX 550 Ti almost crushed the reference version.
