Hello people.

I have two same GIGABYTE AMD RADEON R9 270 OC cards but
second card is always hitting around 17-20 C higher temperature
than first. I borrowed 3rd card and that one seemed ok as it was
getting same temperature as lower one. Cards with lower temperature
had similar serial numbers and "problematic" one has much different SN.
Also I've noticed "problematic" card is heating very fast and cooling very slow?
I don't know where the temp. sensor is but could it be that cooling system has
problems? I really would like to know if that happened to anyone else because
my theory is that I got this card from problematic batch. Thanks for help.

Greets!
