So I just bought a computer from cyberpower (I know its not the best brand, but i got a good psu) and it has a case that has space for up to 5 120mm cpu fans. But, I made the mistake of selecting the default fan option, which basically means that only 1 or 2 of the fan slots will be filled. And, it just got shipped today. My pc components are: intel i5 4690(no overclock), standard Intel heatsink, amd r9 290 (no overclock), 8 gb xps ram, 750w evga supernova b2 psu.
Will my pc perform fine with just the cpu fan and the exhaust fan? Or should I add another two fans to the front and top sides after it comes?

Thanks!
