General cooling advice

[wimpy]

I have an a10-7860k with a gigabyte mobo, which I built from scratch, using new parts. It has a Radeon R7 250 to complement the onboard R7 - hoping for Crossfire later. It uses a Coolermaster- not sure about the make but it came with the cpu/mobo bundle. The CPU fan faces upward towards a case grill and the Coolermaster sits above the Graphics card. I found that the cpu was shutting down due to overheating. The thermal paste had been applied by the bundle seller - probably with a palette knife. I cleaned it off and used a more moderate bead of AS5. Core temps dropped by 5-7C- still too high. However, when I took off the case side panel, I got an immediate drop of 30C. It's running now showing 5C on all cores but it gets up to a max of 30C when gaming. I would like to be able to put back the side panel but I suppose I will have to incorporate some additional fans to compensate. Should they be set to drag in cool air or exhaust hot air?
I would be grateful for any advice and help.

Thanks for the reply and the advice. I wasn't sure whether the build-up of heat with the side panel in place was due to inadequate cool air entering the case or not enough hot air being exhausted. There is room for both types of fan (with some modifications to the case). I'll take your advice and arrange to add a larger intake fan and a normal exhaust one.

@doyll Thanks for the reply. I've read that link. The case is called a Game Max Nero (fairly cheap), if that's any help. The removed side panel consists of a largish plastic/perspex window, which I am going to modify to accept a 140mm or 200mm fan set to blow air in. In the upright position the mobo is vertical . There is room for a 80mm exhaust fan next to the CPU and cooler.
