Subject: [PATCH v4 3/3] asus_wmi: Set default fan boost mode to normal
Date: Fri, 8 Nov 2019 18:46:52 +0200 [thread overview]
Message-ID: <20191108164652.3223-1-leonmaxx@gmail.com> (raw)
In-Reply-To: <20191108164317.2874-1-leonmaxx@gmail.com>
Set default fan boost mode to normal for multiple reasons:
1) existing code assumes that laptop started in normal mode and that is
not always correct.
2) FX705DY/FX505DY starts in silent mode and under heavy CPU load it
overheats and drops CPU frequency to 399MHz [1]. Setting fan mode to
normal avoids overheating.
