Since the Summit B15 seems to be very similar to the Modern 15, I've tried the configuration by @dirompante (#152). However, there are some issues.
Realtime GPU temperature is wrong. It should be at address 0x80, but the value is always 255.
GPU fan is always running at min. 50% (that's if 0x89 can be trustet to be the realtime fan speed, but's clearly audible). Writing to 0x8a (fan speed 0) doesn't change anything (it's 0 already), but writing to 0x8b (fan speed 1) I can adjust the fan speed.
Please add support for the Summit B15.
