Cooling System and Temperature
The EVGA GeForce GTX 670 Superclocked being a copy of the reference GTX 670, we won’t describe its cooling system in detail. We’ve already done that in our earlier reviews and we’ve mentioned the back-plate as well.
We checked out the card’s temperature while running Aliens vs. Predator (2010) five times with the highest image quality settings in 2560x1440 resolution with 16x anisotropic filtering and MSAA 4x antialiasing):
We used MSI Afterburner 2.2.2 and GPU-Z 0.6.3 as monitoring tools. This test was carried inside a closed system case at an ambient temperature of 25°C. All thermal tests were performed before we took the card apart, i.e. with its default thermal interface still intact.
Here are the results of our temperature tests:
Automatic fan mode
Maximum fan speed
Our sample is rather hot. With the fan regulated automatically, the GPU was as hot as 86°C and the speed of the fan was 2640 RPM. At the maximum speed of 3780 RPM the GPU temperature was 73°C. We can remind you that the reference GeForce GTX 670, with a 52 MHz lower GPU clock rate, would get as hot as 81°C in the automatic mode (at 2190 RPM) and was only 65°C hot at the maximum speed of the fan (3750 RPM). Our replacing the default thermal grease with Arctic MX-4 didn’t affect the temperature of the EVGA card.
