Ok, looking at your case, I see the top and both sides of the front panel are completely sealed. Looks like the diagonal RGB stripe doesn't allow air though either. That leaves only the bottom of the front panel to let air in (and if I'm seeing it right, maybe only the left 2/3 of the bottom).
That isn't even enough vent area for one fan. Having two high static pressure fans in the front might improve the situation, but it's still not going to be great.
In the meantime, what monitor do you have? (Make & model) I can help you reduce the power consumption of your GPU (power consumption = heat)
