HWInfo causing DPC latency with AW17

Hi there,

I've been using HWInfo64 for a while now and I have been getting DPC latencies in the form of crackling and popping on my Alienware 17 (2013 Model) with an i7-4700MQ. As soon as I close the program the DPC latencies are gone.

I do have EC support unchecked and I have HWInfo read the EC sensor in order to allow me to control the CPU and GPU fans separately. I am not sure if there's a way to let me control the fans separately while having no DPC latencies.

EDIT: disabling SW SMI removes fan access. enabling EC support removes my ability to control the CPU and GPU fans separately.
