Fans not working in Acer Chromebook 315 Blorb

Support
1

Hello! Recently installed EndeavourOS on my chromebook and everything is fine, except for the fans. For some reason they are not working and the laptop heats up to high temperatures than it used to when under heavy load.

When I used ectool fanduty 100, here is what it showed:

EC result 3 (INVALID_PARAM)
EC result 3 (INVALID_PARAM)
EC result 1 (INVALID_COMMAND)

For ectool temps all:

--sensor name -------- temperature -------- ratio (fan_off and fan_max) --
EC result 1 (INVALID_COMMAND)
Battery               309 K (= 36 C)               error(rc=-1001)
EC result 1 (INVALID_COMMAND)
Ambient               323 K (= 50 C)               error(rc=-1001)
EC result 1 (INVALID_COMMAND)
Charger               318 K (= 45 C)               error(rc=-1001)

Then for sensors:

cros_ec-isa-000c
Adapter: ISA adapter
fan1:           0 RPM
fan2:           0 RPM
fan3:           0 RPM
fan4:           0 RPM
Battery:      +35.9°C  
Ambient:      +47.9°C  
Charger:      +43.9°C  
 
coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +63.0°C  (high = +105.0°C, crit = +105.0°C)
Core 0:        +63.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:        +63.0°C  (high = +105.0°C, crit = +105.0°C)

I would like to also add that when using ectool version, this is what shows up:

RO version:    bobba_v2.0.787-b03bb629a
RW version:    bobba_v2.0.835-c22c200785
Firmware copy: RW
Build info:    bobba_v2.0.835-c22c200785 2022-02-24 19:09:53 MrChromebox
Tool version:  0.0.1-isolate Jun 23 2023 none

Using Chrultrabook Tool, the CPU temperature doesn’t even show up correctly and there is no options for fan control

IIRC BLORB is fanless, just like all the other Geminilake models
