Does this card only utilize one fan at low temps? As I can only seem to get both working by forcing fan control either through CCC or AB, and it has to be set to at least 82% for the second fan to kick on. Bigger issue is I can't even get either of the fans to spin on boot up, have to force the fans through CCC to even start them. Other then that the GPU still works great (no artifacts or anything) and when I force at least one fan on it stays cool, currently at 27c. I'd like to somehow solve this, but if its impossible I can always RMA. Any ideas?

Specs:
CPU - AMD 955 BE
GPU - Sapphire HD 7870
MOBO - ASRock 970 Extreme3
RAM - PNY XLR8 16gb (4x4gb)
PSU - Zephyr MX 750
HDD - WD caviar 320gb
SSD - Kingston SSDNow 120gb

I have a Sapphire HD 7870 and both fans works at 20% at startup.
It could be because of a invalid app profile in your ccc try a clean reinstall of latest CCC and also a MB bios upgrade it might help
