If you use stock CPU cooler or similar, the air flow from the optional fan disturb the air flow from the CPU cooler and vice versa.
If you use a TRUE, Tuniq or similar cooler there is okey to use it, no air flow interference.
I did use it as it gave additional cooling and brought down the heat on my NB. I don´t remember how much lower it was.
I run my NB between 1,41 and 1,71, depending on how hard I push my memory and to get me the lowest possible tRD and right now I´m on water on my NB and it´s never above ~35C even if I push 1,71 throu it.
