Cooling System: Noise and Efficiency
The reference GeForce GTX 750 Ti comes with an extremely simple cooler that consists of a small aluminum heatsink with a plastic fan on top of it:
The fan is secured with four screws and can be easily removed:
It is a 60mm FA06010H12BNA model from Cooler Master. It runs on ball bearings and has an actual diameter of 55 mm:
It lacks PWM regulation, so its speed is changed through voltage. It doesn’t support speed monitoring.
To measure the temperature of the GeForce GTX 750 Ti we ran Aliens vs. Predator (2010) five times at the maximum visual quality settings and resolution of 2560x1440 pixels, with 16x anisotropic filtering but without MSAA.
We used MSI Afterburner 3.0.0 beta 18 and GPU-Z version 0.7.7 to monitor temperatures inside the closed computer case. The computer’s configuration is detailed in the following section of our review. All tests were performed at 25°C room temperature.
Despite its simplicity, the cooler is capable of keeping the GPU temperature within 70°C and remain comfortable in terms of noise level:
When we manually set the fan at its maximum speed, the GPU temperature dropped by 8°C - down to 60°C:
The noise level is low indeed. When regulated automatically, the GeForce GTX 750 Ti's cooler is hardly audible against the background noise of a quiet computer.
