All you're saying points to the transmission. If you don't have the clutch pressed in, the revs of the engine continue to the tranny. When you have the clutch pressed in, the tranny and engine are not connected. The fact the noise stops when you have the clutch pressed in, makes me think the tranny is your issue.

How many miles?
How's the tranny lube?
Have you checked the level or changed it?

I had a Dodge Raider that whined in every gear. It sounded like an old dump truck! It went that way for a looong time until it wouldn't go into 4th so I changed the tranny. The whining then stopped.

Speed up until 40-50 mph then put in neutral and coast... Experiment by pressing and releasing the clutch pedal. Repeat but in 5 th gear without pressing the accelerator.

A failing air oil separator can also cause a hissing blowing noise. But this will follow the rpm directly.

I am also afraid that the transmission is the cause. The sound is more like fan, but still. Transmission is smooth to put in gears. Bought the car a month ago, so have not checked gear oil yet. Will put that on the list, and see if sound changes.
Car has 145000 km on the clock.
