Talk:Fan control scripts
Wyrfel, are you sure the recent (19:54, 27 Oct 2005) cosmetic change was a good idea? The extensive chunks of code make it hard to grok the structure of the article in the absense of separator lines (which "===" doesn't have). --Thinker 22:10, 27 Oct 2005 (CEST)
We can discuss this. From my point of view, the chunks of code distinguish themselves from each other quite well, because they are each in one code block.
I do not like the = section level - and so far we avoided them on all pages - because
- it generates H1 headings, which is the same as the page heading,
- having more than one level with the hbars is confusing/less readable, because they are not very well distinguishable. This way i.e. the "Other" section looked like a separate empty secion.
I think the way it's now, the separator lines make it possible to easily distinguish the different main sections, while when you have both levels with separator lines, an additional task of distinguishing H1 and H2 separators is necessary.
However, i see your point as well and would like to hear more opinions/arguments.

bash script with fine control over fan speed (for unpatched kernels)
Moved to the article page, after joint development by Spiney and Thinker.
Note that the fan levels, thresholds and anti-pulsing hacks are system-specific, so you may need to adjust them.
I think it'd probably be nice to have a table of the suggested values here. Those in the "unpatched kernels" script seems to work fine on my R52, but the other scripts all have different values.

Sensor-specific variable-speed script
Here's a new variable-speed control script that lets you define the temperature range separately for each sensor. To keep things simple, it auto-computes the trip points (unlike the current script). Works well on a T43, and (just barely) keeps the fan off most of the time with CPU undervolting and fglrx set to maximum power saving. Feedback on other machines would be appreciated.
Any idea what are the sensors at EC offsets 0x79, 0x7A, 0xC0, 0xC1, 0xC2? On the T43, 0x79 seems to be the same as the HDAPS sensor (it never deviates by more than one degree from what the HDAPS sensor tells directly), but I don't know where it's located. Sensor 0x7A is uncorrelated with disk temperature and activity, so it can't be HDD like reported ofor R52. Sensor 0xC1 seems to be under the palm-rest (see discussion in Talk:Problem_with_fan_noise).
This version also lets the EC read the RPM sensor every few minutes even when the anti-pulsing hack (which normally prevents this) is in use.
Script moved to the article page.
Feedback very much welcome.

Fan enable/disable scripts
We currently have two types of scripts -- the old ones which only enable/disable the fan, and the new ones which control the fan speed. Do the latter supercede the former, or do we know of models on which only enable/disable works? Maybe eventually the enable/disable scripts should be "archived" in the talk page to reduce clutter in the article?
--Thinker 00:08, 28 Nov 2005 (CET)
Things seem pretty stable for the variable-speed script and the list of working models looks good. Since it is superior to the enable/disable scripts in regard to both the annoyance and the impact on hardware, I'll change the organization of the page to put that script first (unless someone objects)..
