Have my old Intel CPU Q6600 retired and also changed my old MB against ASUS H97-PLUS The difference with the old CPU's such a huge leap that you have to take it once. However, I have not installed the boxed fan but Tower against a Cooler Master Hyper TX3 EVO cooler replaced. Even with prolonged use of the CPU, I'm not over 42 C come (RailWorks 2015 highest resolution 95 min) So far I have the CPU is not overclocked, the performance to 4.4 GHz enough for me completely.
