noise engine like a whistle
Hi, from time to time I hear a sound in the engine, like a whistle. the sound is produced when the engine is hot. I have recorded 2 videos where the sound is heard. Does anyone know what it can be?

1. In the first video it looks like the engine is not running yet the noise is still there.
2. It seems to come from the central area rather than the side.
3. It almost sounds like squeeking. Like a spinning part not getting lubrication.
4. It only happens when the engine is hot.
Have you checked the fan? The big one on the radiator.
