Engine too loud

Qatar Hmmmm!
Are you running Siam sand tires?

I would have thought you had a viscous coupling hub on your 4x4 fan.
The fan shouldn't be fixed, do you have a shroud on radiator??.
Maybe someone fitted a fixed Steel 6 blade fan, very noisy option.
will see what pics reveal first. But fans very noisy.

Not yet. I was told they are not really any better than HT on the dunes. And that they are horrible on road. Is that true?

Viscous coupling meaning fan speed not related to engine speed? Will post pictures up soon.

Pretty much - they're only good for inflating to 60 PSI and doing burn outs. Actually at 60 PSI, they offer almost zero rolling resistance so they're good for driving fast on road, but the handling is pretty bad. Especially when they're cold - wobble like crazy.
I would never fit them

If you use an underbody coating, make sure not to get it too close to heat from the exhaust system.

I have stripped the inside and applied Dynamat Extreme throughout entire floor pan/ firewall as far as possible. Frustrating job but great results

and expensive too. Did you use it on the doors/roof?
