Add fan config for HP Pavilion Gaming 15-ec2xxx

Device: HP Pavilion Gaming Laptop 15-ec2xxx (434L5EA#AB8)
CPU: AMD Ryzen 5 5600H (Cezanne)
GPU: NVIDIA GeForce GTX 3050
BIOS: AMI Aptio V, version F.31

EC Registers

Fan Read Register Write Register Range
GPU 179 (0xB3) 45 (0x2D) 0-94
CPU 177 (0xB1) 44 (0x2C) 0-100

Fan Curve (6-step balanced with hysteresis)

  • < 45°C → 0% (silent)
  • 45°C → 25-30%
  • 55°C → 40-45%
  • 65°C → 60-65%
  • 75°C → 80-85%
  • 82°C → 100%
  • Critical: 90°C (EC takes over)

Tested and working. Both CPU and GPU fans independently controllable.

Tested on HP Pavilion Gaming Laptop 15-ec2xxx (434L5EA#AB8) with AMD Ryzen 5 5600H, NVIDIA RTX 3050, and BIOS F.31.

EC Registers:

- GPU Fan: Read=179 (0xB3), Write=45 (0x2D), Range: 0-94

- CPU Fan: Read=177 (0xB1), Write=44 (0x2C), Range: 0-100

6-step balanced temperature curve with hysteresis for both fans.
