62°
57°
62°

i would recommend a fan at the rear and a fan at the front so you will have some airflow in the case,this will help reduce the temps in general,do you have any fans in the case??i will add a link for a coolermaster 120mm case fan below,this is just a suggestion

But, i cant put a fan in the front since the front part of my case is closed only at the side there is a fan and at the back. So my fan positions right now are at the side and at the back of the case. Also, i don't know where to buy that kinds of fans here in the Philippines, i always look for that kind of fans here, and i cant find one.

now, when i have installed another fan at the back, it seems like nothing changes in my temperature when playing a game like FIFA 13, my cores go like 70, 68, 69, 68..
