AESTHETICS AND COOLING (GTX 970 | 980) The GTX 970 uses a similar cooler as the GTX 980, thus I will cover both here. Both are built around the familiar WINDFORCE design, but the 970 makes use of the 3X model cooler with some creative metal moulding that make it ever so pleasing to the eye. At least over and above the previous generation efforts, which in 2015 do look rather bland. As is the norm with the G1 cards, GIGABYTE includes a back plate much like with other competitors and it’s as appreciated here as it is on those graphics cards. For the GTX 970, the primary selling points are the four 6mm heat pipes which make direct contact with the GPU core and anti-turbulence fan blades. Given that both the GTX 970 and 980 have relatively low TDPs one would have thought that GIGABYTE would use the same cooler on both cards, but the GTX 980 has an even beefier cooler, which may be the reason why it had near identical operating temperatures to the GTX 970, even though it shouldn’t in theory. The GTX 980 model uses the 600 WATT cooler as first introduced with the GTX TITAN Black GHZ edition. The cooler that was capable of taming that beast is installed on the GTX 980 and needless to say that it is truly no challenge for it to keep this GPU under control in all circumstances. This model has five 8mm heat pipes, an additional 6mm heat pipe and I believe a denser fin distribution than the WINDFORCE 3X cooler, all of which result in measurably better cooling capabilities. Both cards rarely hit the 70’C mark (in an enclosed case with the GPU operating at the overclocked settings you see represented) which is particularly low considering that a GTX 760 in the same chassis using a 3rd party cooler re
