GEEZ! I still have my original ThermalRight Ultra 120 and as old as it is, it is still on the Intel and AMD lists.
I don't think a difference of 2 degrees Centigrade is anything to get excited about unless you are very hardcore gamer; into some very serious overclocking; with a case that has very bad ventilation, bad airflow, and bad cooling; and you're on the verge of frying the entire pc while trying to destroy alien invaders.
