Power, temps and noise
There's not a lot separating the GTX 660, 650 Ti Boost OC and 650 Ti Boost.
Palit's dual-fan cooling is better at keeping a (slightly) overclocked GTX 650 Ti Boost cooler than a reference card. A fact made all the more impressive by dint of the near-silent operation.
Logs show the fans to spin at 1,100rpm when the GPU is idling, rising to no more than 1,400rpm when subjected to 10 minutes of Far Cry 3. Palit's cooling is small, sensible and effective.
