We all know the Maxwell GPU is an extremely power efficient GPU, our SC cooler was overbuilt for it and allowed us to provide cards with boost clocks at over 1300MHz. Also we would like to mention that the cooler passed NVIDIA Greenlight specifications.ĭue to the GPU small die size, we intended for the GPU to contact two major heat pipes with direct touch to make the best heat dissipation without any other material in between. There are 3 heat pipes on the heatsink – 2 x 8mm major heat pipes to distribute the majority of the heat from the GPU to the heatsink, and a 3rd 6mm heatpipe is used as a supplement to the design to reduce another 2-3 degrees Celsius.

“The way the EVGA GTX 970 ACX heat sink was designed is based on the GTX 970 wattage plus an additional 40% cooling headroom on top of it. Since then, we’ve contacted EVGA and asked for a response to give any substance to the claims and if the cooler design was intentional. Recently, we covered a story on the new EVGA GeForce GTX 970 ACX having a possible design flaw or manufacturing defect where the GPU die only makes contact with 2 of the 3 heatpipes included in their cooler design.
