Internet forums and rumor mill sites have been ablaze with chatter regarding overheating PWM circuits and memory chips on EVGA GeForce GTX 1070 and 1080 graphics cards fitted with the company's ACX 3.0 coolers. EVGA has issued a formal response regarding the problems, and offers two different remedies that can be administered by users without shipping their cards in for service.
EVGA says the PWM circuits and memory chips run "marginally within spec" while "under extreme circumstances," particularly when running stress-test programs like FurMark. The company says GPU temperatures are around 70° C when running the notoriously-demanding FurMark stress-testing tool. The cards' thermal management sets the fan to approximately 30% of its maximum speed during these conditions. EVGA will offer BIOS updates to raise fan speeds in order to combat potential overheating, and will cross-ship cards for users uncomfortable with flashing the BIOS themselves.
The manufacturer is also offering optional thermal pad kits for owners of affected cards. The kit is available free of charge, but users must remove the cooler from their card to install it, as the company hasn't offered to cross-ship cards for this purpose. The company will still "stand behind its customers with full warranty and cross-shipment" in the event of accidental damage during thermal pad installation. EVGA hasn't specified whether or not future cards will include the thermal pad kit from the factory.
The full list of affected cards, EVGA's press release, and the link to request a thermal pad kit can be found on the company's website.
