Exiting HPFC may not be the same as never running it all. I will have to disable it & see what happens. Since HPFC is in the Windows Startup, it is initialized & running prior to HWInfo64.
If on your notebook the "reset cpu temp" value is other than 00, you can change it at "HP32stop=xx". When HPFanControl closes, or when the userĬhanges from smart or manual mode to bios mode, the program resets the real CPU temp value, by writing 00 at byte 38 and also resets the fan speed.
Using 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.
