I have a da9 integra, stock, and as per the title, I'm having temp issues.

Normal urban stop start driving is fine, temp guage reads cold on startup, settles down to roughly 11 oclock after a few minutes of driving, and stays there nomatter whether im driving conservatively or having a good ol time.

However as soon as I get to any decent stretch of road, into 5th, cruising, temp drops in a big way, down to barely above the cold line. I would expect that due to the amount of air moving over the engine at that constant speed that the temp would drop a bit, but this is drop is almost 2inchs of needle travel which seems excessive to me.

Advice would be appreciated
