your fans will draw a tiny bit of power like 1-2 amps each so i doubt its that but without full specs of your build i cant say for 100% sure
Actually now that I'm really thinking bout it... if you put the two lower cf/m fans as the pulls on top, and your higher cf/m ones as the push on the front... and if you can move the HDD bay out of their way (if you don't really need them cooled) that would be the way to go to lower the case temp and most likely the CPU temp a little too... there is something wrong with my brain today...
ur cpu temps r fine.
ur gpu is running a little hot. have u installed MSIafterburner? when ur gpu is on full load what's the fans speed?
what's ur room temps?
