I noticed lately that when i turn off the car there is noise coming from the hood, sounds like the fan or radiator or something please if you guys know symptoms let me what's up, i am worried The noise goes on even if the key is out of ignition.

 

This is normal. Fan runs until engines drops below certain temp. This is a known Honda feature.

 

The fan can run up to 8 minutes after the engine is turned off. That is normal.

 

They said it already. Just check your coolant level to see if it is where it is suppose to be.

 

And be damn carefull when reaching in anywhere near that fan. It could come back on, it's controlled by a thermister (temp switch).

 

^ Sound advice!
