If you added "(medium speed)" to the command line, then this would be wrong.
But i get
-bash: syntax error near unexpected token `('
when i try to do this with a regular file address after ">".
By googling i found this candidate:
http://unix.stackexchange.com/questions/82246/how-to-control-thinkpad-acpi-via-procfs-rhel-6-4
"# echo 5 >/proc/acpi/ibm/fan

"Fan control operations are disabled by default for safety reasons.
To enable fan control, the module parameter fan_control=1 must be given
to thinkpad-acpi. [... detailed instructions ...]"

One should of course try to find out what is supposed to be installed
by package "thinkfan" and why your Debian does not find it on the
attempt to install it explicitely.
There is a package "thinkfan" and it gets built for i386:
https://buildd.debian.org/status/package.php?p=thinkfan
https://www.debian.org/doc/manuals/debian-faq/ch-pkg_basics.en.html
at the end of paragraph 7.6 says that the failed "post installation script"
should be on your machine in
/var/lib/dpkg/info/thinkfan.postinst
So what do you get from
ls /var/lib/dpkg/info/thinkfan.*
If there is a thinkfan.postinst : What is its content ?
*.postinst in general riddles me. I can see a file acpi-support-base.postinst
in
https://sources.debian.net/src/acpi-support/0.142-8/debian/
but no bc.postinst in
https://sources.debian.net/src/bc/1.06.95-9/debian/
although both .postinst files exist on my Debian 8.
The ./debian directory of package "thinkfan"
https://sources.debian.net/src/thinkfan/0.9.3-1/debian/
does not have a file thinkpad.postinst either.
So there seem to be automats which produce .postinst at packaging time.
(I need to read more Debian packager manuals ...)
Have a nice day :)
