If you think that "tskin" code is the only thing that impacts fanspeed itself, then prove me wrong that you could reduce the fan speed by configuring it running max OC in handheld. That code are the only parameters you can configure. There are other codes out there in another system setting structure that also exists which is why you can never reduce the fan speed just by changing the "tskin" code itself which why ive said this code is irrelevant....
