Insulating Large Void in Attic
I noticed with the weather changing a cool section in my attic. Using an Basic infrared Tool and app on my phone, I pointed it to an angled ceiling in my kitchen that is approximately 3 x 28 feet. The camera definitely shows a difference in color from other areas.
I have done reading that states not to fill voids with foam. Could pink fiberglass blow in insulation be used in this cavity?

If it's a catheralize ceiling, no, blown fiberglass would be too risky in your climate zone.
If it's on a sun exposed south facing pitch you could probably get away with blown cellulose, even though it's technically a code violation.
Do you have soffit to ridge venting on that roof pitch?
This is a north facing wall. There are no vents in the soffits or ridge due to completely foamed attic. Somehow this section was missed and I’m searching ways to correct this.
I noticed a lot of humidity where the warm south meets the cool north in the attic.
Any suggestions? Thank you’
How deep are the rafters in that section?
I’m not sure as most are under foam from the top attic view. Can see a small gap the length where the angled ceiling meets the flat ceiling. I believe someone may have stated 4” Board but was referring to the side walls in the attic that run perpendicular to the flat ceiling.
