11/13/2023 0 Comments How to do fancontrol with biosUsing a dec to hex converter -, start writing values lower than 39C so you can find at what temp the fan turns off. To find this value on your notebook, open RW -, go the the EC (embedded controller) and double click byte 38 to edit it. ini as the temperature where the fan would turn off on its own. (default=31 on 4530s)Įdit XX in the first line of this. The "fake" CPU temp can be set by editing HP32start=XX. This enables full control of the fan and uses the GPU temp as reference for turning the fan on/off/faster/slower. When the program starts, it locks the CPU temp at a low value. Without this setting, HPFanControl will not be able to turn the fan off when you use the laptop with AC power. IMPORTANT!!! Disable "Fan always on while on AC power" in the BIOS. Tested on a 4530s with integrated HD3000 GPU. HPFancontol for HP ProBook 4530s and maybe others in the series. Maybe this helps from the Instructions for HPFC Fan finally shuts off & you're stuck at 963. Restart HPFC, current & min are 963 max is 3300. Fan speed read 3300 rpm (min, max, current). Once both are running for a while & the fan comes on, your speeds agree.Įxit HPFC & all is different. Looks like an offset (480) & a scaling error (2x), but not all the time. Your max reading is 7021rpm (clearly wrong!), min reading is 963. When HPFC goes to 0, you're stuck at 963. Waited until fan came on at around 3000rpm & your reading is in agreement with HPFC reading. I am running the HP Fan Control as mentioned earlier. I choose "Continue" & it reads 963 rpm, when fan is at 0 rpm, then quit & start again & choose "Disable Sensor". exe & choose "Sensor Only" & it takes a very long time for detection. I don't expect easy answer here, but maybe someone could give me a hint where to start debugging? I found some posts that it may be related to the Differentiated System Description Table.I see the reading, but it is incorrect. Re-flashing BIOS solves the issue as long as Linux is not booted.After that it's not important if it's Linux or Windows. It turned on to full speed and remained so. After booting into Linux the issue was back as soon as CPU temperature rose enough for the fan to turn on.Having computer back I operated Windows for some time (week or so) to see if the issue is gone.I gave computer to the repair and I was amused when they told me that re-flashing BIOS made fans work properly on Windows (they refused to check on Linux.). Then I though that it may be a hardware issue. It turned out that indeed fans were still at full speed on Windows. First I though of trying reboot to Windows to see if problem persists.One day (don't remember when, not using this notebook very often) fans started to work at full speed when using Linux (it was 4.x line kernel).Every attempt was followed by a BIOS re-flash. I also tried upgrading Ubuntu to 5.x kernel line. I have a strange (and annoying) problem with my ASUS UX32LA notebook: I suspect that multiple Linux distros (Ubuntu 16.04 and newer major versions using the 4.18.0-17-generic kernel, plus Fedora 28 LiveUSB), somehow breaks BIOS control over fans.
