Roaring engine sound 04 murano

Hey, i'm new to this forum and I already got a small unknown problem.

Has anyone who drives a murano experience a roaring engine car sound when your driving the car? My murano makes a roaring like the sound of almost a mowing lawn everytime i drive above 60km. I brought the car into the garage to get it fixed but they said they couldnt find the problem. I don't mind about it now but has anyone else experience this before?

i'm not sure whats the problem really if you have any suggestions on how to fix this it will be great cuz that roaring sound can get a bit ignoring sometimes. But now i think of it as a racing sound instead haha. But i prefer quietness then roaring sound

depending on from where you are at, temperature wise, it sounds like the fan clutch is engaged. if it is really cold the ambient temperature may not get high enough inside the engine compartment to liquify the silicon in the fan clutch. after driving for 20-30 minutes shut the vehicle off and try to spin the fan, if it doesnt spin or difficult to spin the fan clutch is engaged or locked up. it should spin relatively easy unless temperatures in your area are in the high 90s or above. in the higher temps the fan clutch will engage as well to improve cooling.

You might want to pop the hood and look to see whether the fan is electric or not.

hmm maybe i should.. what happens if its locked? is it possible for me to fix it or should i bring to my auto place to get it fixed.. but then again I have already brought it there 3 times and they havent found the problem.. Either their idiots or maybe its my entire engine thats going crappy... and this is a 2004 murano... so its considered "old" now.
