HP Laptop Dust Removal Software?? - HP Support Community - 2297239
April 4, 2015 - I hear that Lenovo has a program ... is dust cleanup. It maxes the fans out for a few seconds then slows them down and maxes them out again and repeats that for some time. I think this would be really benifical for HP to add to its HP Support Assistant or Advisor (or both) software...

November 11, 2019How to control the fan on an HP EliteBook laptop (NoteBook FanControl or similar)
The NoteBook FanControl documentation notes that if you can't write to the EC fan registers, then you might need to set the EC to "manual control mode." I tried to find if any EC register would toggle manual control mode by writing a hacky script that does the following: Test each EC register to see if it is writeable Set the value of each writeable register to something else (at first I tried values close to the current register value, but I ended up just trying all decimal values 0-255) Try changing the fan speed write register, FTGC 0x2F (47), and the other fan-related registers used in the nbfc EliteBook configs: CRZN 0x22 (34) and TEMP 0x26 (38) to see if any of the changes actually stick Unfortunately, none of the changes to the fan-related registers were ever accepted, no matter what values I set for any of the writeable registers. So either multiple EC registers need to be changed in order to enable writing to the fan registers (e.g., one to enable manual control mode of the EC and one to enable manual control of the fans), or fan control on the EliteBook 845 G9 is totally locked down, which seems more likely. This is a huge letdown because I love everything else about this laptop, but I am often working late at night in a silent room, and fan noise drives me bonkers, so manual control over the fans is a must. Right now my current workaround is to use Universal x86 Tuning Utility to set the temperature limit to 75C (or 65C on battery) to prevent the higher fan speeds from kicking in, but I hate gimping performance to that extent. For the record, here are the EC registers that my hacky script determined to be writeable (in decimal format): [17, 18, 20, 45, 46, 70, 71, 72, 97, 100, 116, 121, 122, 123, 128, 134, 135, 136, 139, 154, 190, 197, 227, 228, 230, 231, 234, 236, 239, 240, 243, 244, 247] More on reddit.com

@ravindersin7554 since iFixit does not yet have specific guides for this laptop, use something like this video to work on it. Remove the fan and clean it with soft brush and a few puffs of compressed air. Double check that it does not make any noises and that the fan blades are not damaged etc. IF there are any issues with the fan, do go ahead and replace it. The cost for replacement fan is not to high and can ultimately ensure that your computer will work for many more years. · If it does get to hot, and you want to do more than just work on the fan, you want to consider replacing the thermal paste. Also, clean all the air inlet vents etc.

is there an easy way to clean the fan - HP Support Community - 6059146
April 1, 2017 - You mention the two ways to clean a fan. The first is to try to clean out the vents with compressed air when computer is off and cold. The only way to really clean the fan is to remove it and clean with canned air or soft brush. Many times a small carpet of dust will form where the fan blows out the air through the heatsink (radiator) which you can remov by removing the fan.

r/Hewlett_Packard on Reddit: How to control the fan on an HP EliteBook laptop (NoteBook FanControl or similar)
June 29, 2023 -
Hi all,
Does anyone know of any software, or any settings/configs in NoteBook FanControl, that can successfully control the fan on an HP Elitebook 845 G9 (Ryzen 6850u) on Windows 11?
The closest I've gotten to successful control is by using the nbfc-revive fork of NoteBook FanControl (https://github.com/UraniumDonut/nbfc-revive) by following these steps:
-
Replace OpenHardwareHonitorLib.dll in the program's Plugins folder with the version from here: https://github.com/UraniumDonut/nbfc-revive/issues/27#issuecomment-967684864
-
Load the HP EliteBook 745 G5 config. This config confirms my own findings from probing the EC registers (https://github.com/hirschmann/nbfc/wiki/Probe-the-EC%27s-registers) that the current fan speed read register is 0x2E (46) and the desired fan speed write register is 0x2F (47).
Using the above config, I can see the fan speed (most utilities are unable to even report the fan speed), but I am unable to actually change the register via NoteBook FanControl, its command line tools, or RW Everything. Any changes to register 0x2F (47) are simply ignored.
Other tools I've tried that don't work:
-
Fan Control (love this for my desktop PC, but no controls are found on my EliteBook, and LibreHardwareMonitor can't even see the fan speed)
-
Universal x86 Tuning Utility (the only other utility that reports the fan speed, but I can't figure out how to change it)
-
SpeedFan (no fans listed)
-
Argus Monitor (no fan or motherboard options)
-
HP Omen Gaming Hub (no fan options)
-
HP Omen Command Center (system not supported)
-
AMD Ryzen Master (won't install)
-
BIOS (no fan options other than enabling/disabling 'always on')
-
Edit: HP Command Center (no fan control, cooling profiles don't do anything; see my reply to u/Terry1017)
Thanks!
Edit (May 2024): I have given up this task as impossible. I used this thread to record everything I tried; see especially my comment about testing the embedded controller (EC) registers. The good news is that the 845 G9 fan is probably the quietest fan I've ever heard on a Windows laptop (except for very annoying on/off cycling around 50 C) and is nearly inaudible at the lowest speed, so I've decided to just set the BIOS option to keep the fan on while plugged into AC power. See my reply to u/Neurrone for further discussion.

Why the fuck do these OEMs do shit like this? Just use standardized fan registers so the software can find them. Even HWInfo can't report fan SPEED let alone change it! I can't even see the current RPMs!

How to Clean HP OMEN Laptop Fans for Peak Performance | HP® Tech Takes
September 4, 2025 - Those powerful fans pulling air through your system also pull in dust, pet hair, and debris. Over time, this creates insulation where you need cooling most, causing thermal throttling that turns your gaming powerhouse into a stuttering mess. This guide provides professional cleaning techniques that take just 30 minutes but can drop your temperatures by 10-15°C, eliminate throttling, and extend your laptop's lifespan by years.

Do yourself, take screw off, take back plate off, unplug battery, unscrew heatsink, easy take if off. Repaste if you can, wipe with dry cloth, unplug fan, unscrew fan, clean it with brush. Watch omen disaasmbly better guide, if you unsure how to remove, prevent breaking it.
