aida 64

Short backstory: I’ve been facing an overheating issue on my ASUS Vivobook 14
M1402IA-AM173 laptop running Manjaro (kernel 6.5.3-1-MANJARO, scaling_driver
amd-pstate) with 16GB of RAM and a Ryzen 7 4800Hs processor. Every time I
launch applications like PHPStorm (project indexing) or run PHP unit tests
(Paratest), all CPU cores max out their frequency to the maximum value.
According to htop, it reaches 4300 MHz, and even when the processor heats up,
it doesn’t reduce the frequency to prevent overheating. Eventually, it hits a
critical temperature of 105 degrees, and the laptop shuts down.

I tried running tests on Windows 10 with AIDA64. Within two minutes, I ran them
and came to the conclusion that Windows seems to incorrectly detect the fans.
They seemed to be spinning fast, but AIDA was showing only 500-700 RPM (I’m not
sure about the accuracy). However, the laptop did not shut down, and the
processor was running at around 3300-3500 MHz and 90 degrees Celsius plus or
minus.

I decided to attach a video showing how it happens. If it’s not too much
trouble, please take a look at it.

After long days of suffering and searching for a solution, I was able to find a
configuration where my laptop wouldn’t overheat.

Here’s what was done:

1. Install tlp (below I will attach the configuration).
2. Add k10temp Then enable it (sudo modprobe k10temp).
3. Add the following line to the grub configuration: amd_pstate=passive. Update
grub.
After this configuration, my processor frequencies stayed around 3900-3700 MHz
±. The temperature at its peak was 93 degrees, I saw such numbers once. Mostly,
it ranged between 86-90.

works on: 6.5.3-1-MANJARO

CPU_DRIVER_OPMODE_ON_AC=passive
CPU_DRIVER_OPMODE_ON_BAT=passive
CPU_SCALING_GOVERNOR_ON_AC=ondemand
CPU_SCALING_GOVERNOR_ON_BAT=ondemand
CPU_BOOST_ON_AC=1
CPU_BOOST_ON_BAT=0
CPU_SCALING_MIN_FREQ_ON_AC=400000
CPU_SCALING_MAX_FREQ_ON_AC=3700000
CPU_SCALING_MIN_FREQ_ON_BAT=400000
CPU_SCALING_MAX_FREQ_ON_BAT=2900000
CPU_ENERGY_PERF_POLICY_ON_AC=balance_performance
CPU_ENERGY_PERF_POLICY_ON_BAT=balance_power.

It seems like something is not working correctly with the fans or the
processor. I've tried it on another system, such as Ubuntu, and the same issue
persists. Right now, everything is functioning, but only with workarounds. I
was advised on a forum to highlight this bug and was directed here.

I'm 99.9% sure it's either a hardware failure (malfunctioning fan?) or a buggy
bios.

The kernel cannot make your CPU run at unsafe temperatures. It's the CPU task
to throttle if it heats up.

It's great you've found a workaround but it's not a kernel issue and there's
nothing that can be done in the kernel to fix it.

Hello! Thank you for your response!

I installed latest bios 310.

Alright, I started dealing with pwmconfig and fancontrol. I immediately
encountered the issue that I don’t have pwm1 :slight_smile:

Here’s the ls output:

device  fan1_input  fan1_label  name  power  pwm1_enable  subsystem  uevent
Here’s the pwd:

/sys/devices/platform/asus-nb-wmi/hwmon/hwmon5
From what works for me:
echo 2 > pwm_enable - works
echo 1 > pwm_enable - says it’s an invalid value
echo 0 > pwm_enable - turns the fans on at full speed. Honestly, I’ve never
heard them running so powerfully. However, I think you’re right; this fan has
potential, and perhaps they could cool the processor effectively.
