vavet,

I've added a comment explaining the values: https://github.com/bitonic/x62-fancontr ... rol.c#L155 . I still don't really know what they _mean_, but that's the effect they have on the fan speed.

Given the PWM terminology one would think that the fan speed regulates the pulse width modulation frequency, but there are a few jumps in the 0-255 range and even in the range where the change is smooth it does not seem to change the fan speed linearly

now onto the next problem: the fan emits a very high frequency vibration at low speeds (which i'm hearing for the first time since it was always at high speed before)

Other than that:

Battery charge and discharge times are a bit... say, they go mad sometimes. I've installed BatteryBar and it worked just fine with both charging and sicharging times... for two days :) then I needed to reinstall it to make sure what is the exact working time and how long would the system stay alive, and still it jumps every 5 seconds to different value, ranging from 3,5hrs to 8hrs on fresh battery (update every 5 seconds).

Is there any reasonable way to create own powerplan on those systems in W7? I guess you can't change voltage on i5 without changing the clock, but a good utility would be nice in here.

You can set a voltage offset (read: undervolt) the X62 with Intel XTU or ThrottleStop (I recommend the latter: Less processor usage, built-in C-state check window which you need anyway for configuring the X62 to save power).

Hi,
Fan control issues here.
Has anyone figured out what the numbers mean in the config file that go along with the Windows fan utility that was posted?
I can't quite figure out how it transitions from one state to another, and additionally it seems to go into states that aren't in the file sometimes (as indicated by the scrolling command line output).

It mostly seems to work for about 10 seconds, then the fan goes silent. Does this have anything to do with how the system cooling policy is set?

I was trying to transcode some video and I ended up with a thermal shutdown...

Hello Rafael,

I'm fighting pretty similar issue here for some time and it seems that the fan behaviour depends on many variables.

There are 4 values in the text file:
a,b,c,d
[up temperature], [down temperature], [fan speed - PWM modulation], [NULL]
up is when to start this speed
down is when to drop to the previous line
fan speed is in 0-100 range (actually did not try more)

When working w/W7 this thing did not work for me, at all. It worked for - say - 30 seconds, and then the fan started living its own way. No matter what I put in there. fullstop.

However, when I installed W10 it actually started working... the opposite. Figuring the numbers in the default thermal table it seems that the lowest fan speed should be there for "100", and the highest one for "1" - and it worked this way for W7 (for a very limited amount of time, however). On windows 10, while on A/C, it works the opposite - highest fan speed is set at "100", and lowest at "1".

I was happy when I found the solution until I switched to battery. Now the nasty thing is living completely on its own; floating between max and min speeds of the fan all the time when the .exe file is on. Another thing is that the temp monitor is unable to execute from W10 autostart (while all the other apps do not have this limitation).

Still fighting. Will let you know when I make it.

EDIT: OK, it works, and it works perfectly. Maybe the only thing I'm missing is sething this app in startup, but this does not seem to work at all. All I did was a BIOS update and W10 update.

Another thing: have no idea if this has been already mentioned, but "BatteryBar" app gives true charge/discharge rates under Windows.

Has anyone managed to update the Intel CPU microcode on an x62?

I'm suspecting that the microcode updates from Intel check the CPU version, and as the x62 has an ES (Engineering Sample) CPU, it will not update.

There are of course other reasons to update the microcode, but patching the Spectre variant 1 vulnerability (https://spectreattack.com/) is my main concern. And we have probably not seen the last of these kind of CPU vulnerabilities that need a microcode fix..
