> How can I control fans speed on my laptop - Lenovo IdeaPad G555?

This depends on which kind of fan device do you have on this laptop.

Fan can be controlled in different ways, e.g.
1. ACPI. (the generic way)
2. platform driver/native driver (need platform specific code)
3. BIOS (transparent to OS)

please attach the acpidump output of your laptop so that I can check if there
is ACPI fan device or not. Although according to the output of "acpi -c", the
answer is probably "no".
