Seems like lately almost every stop light I pull off from my fan on my truck is making that really loud wind/roaring noise really loud. Is it going out?

normal.

they move a rediculous amount of air, and as a result, are rediculously loud.

See thats the thing. I use to never hear it.. Quiet as could be.. Now its super loud!!

Where are you located? Is it 90 plus? I know where I live its been 90-113 over the last month.

perfectly normal for summer temps. mine starts to do it when its 85* and above every darn summer.... you got to love the lly's!

If you want to fix GM's error with the LLY or tow heavy you should think about the V2 from TxC. Install and say bye to fan noise and high temps.

alright, thanks.. and yes its been extremely hot here..

Yeah... well... true. I guess if you're hoping to kill the sucker some day, it can be described as a "sickness", though this is indeed behaving as designed. I stand corrected...

Funny one randy....Down with da sickness!

Like the loud fan, it scares the cat and keeps it from crawling into the engine compartment.

Mine still has a little mild morning sickness once in a while.
Never during the hot days empty, and only a little at the top of the mountain towing very heavy at 11k feet in 80-90 OAT on a 5-7% long grade, thanks to the V2 and TxC!!!!!!!!!!!
