Temperature of Gigabyte GV-R797TO-3GD

[Bitock]

Have 2xGV-R797TO-3GD. First card set to PCIEX16_1, second to PCIEX16_3 in the next MB.
My .bat file:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://123 -u XXX -p XXX -d 0 -d 1 -I 13,13 -w 256,256 -g 2 -g 2 --thread-concurrency 8193,8193 --gpu-engine 1090,1095 --gpu-memclock 1500,1500 --auto-fan --temp-target 75,75

Why the temperature is high on GPU0? But when I run one of two cards (use -d 0 or -d 1) the temperature not high 72-73C. Maybe PCIEX16_1 is PCIe 3.0, PCIEX16_3 - PCIe 2.0? Please, help!!!
