What tempratures do you have now?
I don't know. My PC doesn't have thermal sensors.
Such desktops have solve such problems
The reason why I plan to add some fans is that I had a blown capacitor on my motherboard two weeks ago. The technician said that it was because of overheating.
couldnt realy see much sinc you were showing the top of the cpu fan and not the inside of the case itself. but if you need an xtra fan 1 at the top or back blowing out should be fine. where ever it will fit best.
Sorry for my bad photography skills.
