3 r9 290 +7degrees difference between them

post #1 of 15
Thread Starter 
is it normal to have such a big variation of temperatures with 3 xfx r9 290 reference cards?
they are all from same batch +1 serial number apart.

from top to bottom
GPU1 80C
GPU2 73C
GPU3 77C

Is the 2nd GPU is using a more quality die? it seems weird to me that the 2nd GPU is so much cooler. First I thought maybe defective sensor, but idk let me know what you think.

is it possible that one is a "better chip" than the others?

You have them sandwiched together, that will cause them to not get the same airflow
