Those are impressively low attic temps. Most attics will be at those temps by 10am.
Also I forgot to mention. I'm not a fan of those vinyl or aluminum soffit vents. They don't flow very much air because of the tiny holes hence they need to be continuous to make up for it. I personally don't use it not so much because of performance but due to availibility. It's not a commonly available product here as vinyl siding is rare as it doesn't meet building code in most city's as its not masonry. Most require a house to have 60-80% masonry for the exterior. Brick and rock are longer lasting and more durable but install cost and repair are higher and they hold lots of heat. The walls hold so much heat they are hot all night and radiate heat inside the house.
I'd like to rip the brick off of mine foam it and side it with hardiside just for the energy savings. Luckily I can in our city but we won't be staying much longer.
