since like no one knew what they were talking about here beyond the heatsinks and fans being independant... start a stress test. if both fans dont EVENTUALLY turn on, you need an rma, download tech powerup gpus (they even have an rog skin one =] )then click your sensors tab when you launch a hefty game (blops 2 or any old game really except armagetron or similarly "low resource" games ) i had a thermal issue and the sensors WILL tell you if this is going on and furthermore the field to pay attention to is PERFCAP REASON, ("Util" the gpu hasnt been drawn from and thus isnt engaged which is common, Thermal, means eather fan, gpu, or mobo failure. they pretty much rebuilt mine once i PROVED something was actually wrong. but theres almost nothing anyone can really do or tell you without redouts or screenies. but if you launch any program that will bring your gpu to its highest state (3d mark, msi kombustor blah blah) both fans SHOULD be engaged. youre right. (from my experience)
