EVGA Responds To Defect ACX Cooler Design Complaints

Apparently there are a lot of people are complaining that the ACX Cooler on the EVGA GTX 970 runs hot due to a poorly designed heatsink that sits off-center allowing only two of the three heatpipes to make contact with the GPU die. Responding to those complaints, EVGA has released a statement saying the cooler was designed that way.

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. 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. Also we would like to mention that the cooler passed NVIDIA Greenlight specifications.
