alienware17 R1(17xR5) fan contorl


New Member

I am using Alienware 17 R1.

If "ec support" is enabled, it will be displayed as fan1 & fan2 and the cpu fan will work but the gpu fan will not work.
If "ec support" is disabled, fan1 and fan2 will be displayed respectively and all fans will operate normally. But I can only control three steps. (cpu: 0, 2000, 4600 gpu: 0, 2000, 3400)

I want to enable "ec support" and make the gpu fan work too.
This is a known (firmware) limitation that has been discussed several times here. Unfortunately there's no fix for this possible/known.
