and will front and back case fans will be enough?
I need a good and cheap fans as i barely have any money left because im buying other pc parts.

Specs -

Intel Core i5 6600 @ 3.30GHz 44 °C

2047MB NVIDIA GeForce GT 730 (Gigabyte) 38 °C

Gigabyte Technology Co. Ltd. H110M-S2H-CF (U3E1) 36 °C

931GB TOSHIBA HDWD110 (SATA ) 29 °C

if they are enough will depend on the heat sources in the case.
an athlon 200g would barely get warm. a 3900k will cook an egg.
