Hi,

max rpm value is set by the system, so shouldn't modify it. We could, but that's too risky.

BTW ODD fan in this model cools the GPU, check your settings.

Thank You Steven;

In past i used other sw to control this that they are no more manteined now; and those allow the CPU fan speed quite to 6000 RPM.
Now the issue for me is the CPU / Processor FAN and not THE GPU graphic card. This for me i a very low value for heavy duty application.

Thank you for your reply,

Luca
