Does adding multiple fans will help in overclocking part

I want to know that does adding multiple cpu fans will help in overclocking stuff. Like if I am having a Intel Core i3 based process and I want to use the turbo boost utility, then the cpu will surely heat at some point. I am having place to add around 3 cpu fans on the entire case. And I had selected 90mm fan which I will be using on the system case. I want some help here to find out what arrangement will be appropriate for keeping maximum airflow in the system.

Case fans will not help you much. They are best to maintain a simple airflow of the cpu fan. If you want to overclock on a limited level then it is best to add a good cpu cooler. There are some budget models in the market which comes with aluminum pipes. This will regulate heat more properly and will give you good cooling. There are quiet big size fans in the market which can keep your cpu cooler at maximum level offering good cooling.
