67 is not average and I would not want my CPU running in the high 60's under load. My I5 at idle would run in the high teens to low 20's at idle. Unload it would average around 37 to 42 degrees.
Are you kidding me? You would have to get delta fans with 2 QUAD rads to meet that (or just a very low-end CPU with no OC). 70 to 80 is about average these days so 67 C is pretty good on load.
