Why did you "cut" anything. They unbolt pretty easily. Anyway, check your coolant level. I had a weird whirring noise almost like a fan clutch. topped off coolant level and have not heard noise since. If using coolant with no visible leaks, it may be your egr cooler(s) starting to go, as I suspect with mine.
