Dear folks, I have problems mining ether. I have 3x 280x, 2, 1 Windforce XFX. After a while mining the PC freezes. The temperature of the GPU is up to 80 degrees Celsius, but I do not know how to decrease these temperatures. I made them clean the GPU, I changed my windows 8.1 to 10, update the SDK and driver catalist.

Can you help me? Thank you.
