1. CPU usage.
Well, if you want decrease usage of your CPU by the game you might change few plugin options, like turning off day/night tint cycle, shadows and even HUD. But it require RPG Maker and/or basic knowledge of Javascript.
If you can't do that yourself then you can, of course, ask someone to do it for you, even game dev, Chyos, himself. Although that may take some time... and probably cost you few bucks.
2. Repaste(?)
Oh yes, additional fan can surely help you with high temperature inside your PC, especially during summer days, although even the best cooling system won't help much if temperature from your CPU can't "travel" very well to your radiator through termal paste if termal paste is old and used.
That's why I always recommend to repaste
if someone has problems with constant high temperature on his CPU/GPU.
But, before you do that, you might want first to check temperature of your CPU with free program like

If it is above 60 during normal use and somewhat around 90 during gameplay, you might want to think about changing your thermal paste. It's not like you're using overclocked CPU, but if you want some quality paste, then the best on the market is Grizzly Kryonaut, but of curse it isn't cheap. If you want something good but cheaper you can buy Silentiumpc Pactum PT-1, CoolerMaster High Performance or Genesis sillicon 800.
And if you afraid of changing it by yourself just ask your local IT shop.
Well, either I didn't know that... or I forget but knew. But yes, if we cut the head, the body will colapse. And then with those preperations we can retake the mine... then free Arenfield from baron... and bring justice, peace, freedom and security to our new kingdom!
