노트북 팬이 항상 8RPM으로 표시됩니다.

저는 다음 사양의 Lenovo Legion Y520을 가지고 있습니다.

나는 그것을 사용하고 있다시판CPU 팬을 제어하려고 합니다. 아쉽게도 항상 8RPM이라고 되어 있어서 실제 팬 속도가 얼마나 되는지 알 수 없습니다.

중요한 경우 내 thinkfan.conf는 다음과 같습니다.

######################################################################
# thinkfan 0.7 example config file
# ================================
#
# ATTENTION: There is only very basic sanity checking on the configuration.
# That means you can set your temperature limits as insane as you like. You
# can do anything stupid, e.g. turn off your fan when your CPU reaches 70°C.
#
# That's why this program is called THINKfan: You gotta think for yourself.
#
######################################################################
#
# IBM/Lenovo Thinkpads (thinkpad_acpi, /proc/acpi/ibm)
# ====================================================
#
# IMPORTANT:
#
# To keep your HD from overheating, you have to specify a correction value for
# the sensor that has the HD's temperature. You need to do this because
# thinkfan uses only the highest temperature it can find in the system, and
# that'll most likely never be your HD, as most HDs are already out of spec
# when they reach 55 °C.
# Correction values are applied from left to right in the same order as the
# temperatures are read from the file.
#
# For example:
# tp_thermal /proc/acpi/ibm/thermal (0, 0, 10)
# will add a fixed value of 10 °C the 3rd value read from that file. Check out
# http://www.thinkwiki.org/wiki/Thermal_Sensors to find out how much you may
# want to add to certain temperatures.

#  Syntax:
#  (LEVEL, LOW, HIGH)
#  LEVEL is the fan level to use (0-7 with thinkpad_acpi)
#  LOW is the temperature at which to step down to the previous level
#  HIGH is the temperature at which to step up to the next level
#  All numbers are integers.
#

# I use this on my T61p:
# tp_fan /proc/acpi/ibm/fan
# tp_thermal /proc/acpi/ibm/thermal (0, 10, 15, 2, 10, 5, 0, 3, 0, 3)

여기에 이라고 적혀 있으므로 EC unknown내가 어떤 EC를 가지고 있는지 알 수 없고 인터넷에서 내 모델에 대한 정보를 찾을 수 없습니다.

s-tui/proc/acpi/ibm/fan,, : 에서 속도를 확인해 보니 항상 sensors8RPM인데, 게임을 하면서 최고 속도로 터지는 소리가 들리면 당연히 불가능한 일입니다.

Windows 10에서는 speedfan팬이 발견되지 않았습니다. 또한 BIOS 버전을 4KCN40WW에서 4KCN45WW로 업데이트했습니다. 변경 없음.

실제 팬 속도를 어떻게 확인하나요?
