The ${name} type, can be

<literal>hwmon</literal> for standard ${name}s,

<literal>atasmart</literal> to read the temperature via
+
S.M.A.R.T (requires smartSupport to be enabled),

<literal>tpacpi</literal> for the legacy thinkpac_acpi driver, or
+
<literal>nvml</literal> for the (proprietary) nVidia driver.
+
The query string used to match one or more ${name}s: can be
+
a fullpath to the temperature file (single ${name}) or a fullpath
+
to a driver directory (multiple ${name}s).
+
When multiple ${name}s match, the query can be restricted using the

<option>name</option> or <option>indices</option> options.

This section slightly departs from the thinkfan.conf syntax.

The type and path must be specified like this:

query = "/proc/acpi/ibm/${name}";

instead of a single declaration like:

- tpacpi: /proc/acpi/ibm/${name}

LEVEL is the fan level to use: it can be an integer (0-7 with thinkpad_acpi),

"level auto" (to keep the default firmware behavior), "level full-speed" or
+
"level disengage" (to run the fan as fast as possible).
+
LOW is the temperature at which to step down to the previous level.
+
HIGH is the temperature at which to step up to the next level.
+
All numbers are integers.

A list of extra command line arguments to pass to thinkfan.

Check the thinkfan(1) manpage for available arguments.
