HP Notebook Fan Control in HWiNFO32 (ROUND 2 - AUTO FAN CONTROL CONFIG) !

[Mumak]

I guess this is an issue of window resize. Try to resize the window so that the button is in the lower area where other buttons are. Then it should work.
I'll also fix this issue and post a new Beta within few minutes..

EDIT: Posted build 1177 on Tech|Inferno to fix this issue.

Also the option of typing fancontrol does not open the Fan Control window.
I also suggest to group the icon beneath the line for the fan Fan1 with the text Fan Control or implement instead a button just before the button Logging Start.

Build 1177 works great. Thank you!

Announcing hpfan: to quickly save/load fan profiles set with hwinfo32 from the commandline

A few pages back I highlighted an intermittent problem I was having with hwinfo32 loading. Mumak was kind enough to provide some pointers on how to program the fan, so I wrote 'hpfan', a wrapper over r-w everything to program the SMSC fan controller bytes. So now I only need hwinfo32's GUI to initially set my fan LUT, then can use hpfan to save the fan settings to file and load them from the commandline. It's really fast and works great

Download, install and use instructions for hpfan are here or linked from setPLL in my sig.

HI, i have a hp g42 250br, and i try very programs to control the fan speed but none works. i install the HWiNFO32 but in sensors don't show any fan.
someone can help me? thanks



EDIT: motherboard hp 1425
processor i3 350m arrandale sv

This depends on the controller used on your machine. Please attach a screen of the sensor monitoring from HWiNFO32.

This model unfortunately doesn't have the required fan controller.

On HP 8740w I got a problem with setup fan speed.
I setup smooth consistent increase of fan speed. But it looks like work only some points. 2nd (1606) work when computer start (or I apply manual fan speed configuration). 5-th (2700) work when computer under heavy load. When it's idle after load fan speed decrease to 3-rd (2014) and stay at this level, and don't decrease more. But if I switch to manual mode and press "Apply and Save" button fan speed decrease immediately to 2nd (1606).


So what I do wrong?

[Mumak]

When you configure the LUT and switch back to Auto mode, then the fan is controlled solely by the fan controller based on temperature and hysteresis. However the problem is that the representation of temperature is in PWM cycles and I don't know how to convert it into degress C to have a more exact fan control.
In case you experience the issues described, it might be because the PWM input doesn't reach the required threshold, or maybe it's not performed because of the hysteresis. I would suggest to try to change the PWM values too or change the steps completely.
If that doesn't help, then it might be required to lower the hysteresis value, which is currently not possible. I can allow this too.

Mumak, can you say what temperature sensor I need to look? CPU cores sensors, as I understand? Doesn't matter what? It's looks like Temp3 related to Core 3 sensor, can you approve this?
Also I investigated, that Temp3 PWM works only in 8-20 range. I didn't saw other fan speeds values at all.

About hysteresis. After fan entered to 5-th (2700) state and then entered to 3-rd (2014) state I waited more than hour (system was loaded just 20 seconds before this). As you see on a screenshot temperature decreased from 67 to 38 C. But fan speed didn't changed at all. I don't think that 20 seconds of load can override one hour of idle.

About threshold. When I applied same settings again fan immediately decreased it speed. And before this test I got 42-44 C and 2nd (1606) fan speed. As you see now it was 38 C and 2014 fan speed.
