Hi,
I’m running two GTX480 + one GTX570 on one machine dedicated for CUDA applications. Faced a problem with cooling fan of the GTX480 card to which the monitor is attached. After about 10-15 hours of continuous action (kernels are run on all three GPUs) cooling fan of that GTX480 starts to rotate with 44% of it’s maximal speed, no matter how high the temperature of the GPU is (it goes beyond 100C easily). Two other cards do control the speed of their fans normally (i.e. increase it when crunching and decrease it to 44% when idling).
What can be done about it ?
Thanks in advance.
