Why is my table saw blade burning oak boards as I make rip cuts?
High tooth count will give smooth results in most cases, but they can heat up in hard wood.  More teeth leads to more friction.  It's probably a fine all purpose blade, but ripping a hardwood like oak, especially very thick boards, is probably a reason to use a dedicated ripping blade.

Ripping blades have 24-30 teeth, and the tooth profile is flat on top.  Some may have a slightly thicker kerf to avoid binding if the board twists or pinches when it's cut.  Each tooth takes a bigger bite, but when you're going with the grain, you can afford to do that.  Fewer teeth means less friction and heat.
