I built my first ever computer a few days ago and I'm not sure if I will need to buy an aftermarket cooler for my CPU.

I have an Intel i5-3450(IB) and on idle I get 39-43 degrees and when gaming it goes to 50-60. Will I need an aftermarket cooler?

I'm checking temps using RealTemp. My case tells me that the temp inside is 23 degrees. I have a Zalman Z9U3. Stock fans.
