Public bug reported:
Lenovo Thinkpad T500 runs hot / on high fan RPM when configured to use
the discrete Mobility Radeon 3650 instead Intel graphics. I haven't
noticed any differences between Catalyst and open source driver so I'm
reporting from Catalyst-configured configuration. Open source is a no-
go!
I use sensors command in terminal to verify temp values:
For intel it's below 2000 RPM and temps circa 40
For AMD it's close to 3000 RPM and temps 45 and higher. Once RPM reaches higher
threshold, it never goes to lower RPM values.
