I have an i7 4770 in a bitfenix comrade case that has two intake fans and one exhaust fan. My cooler is a Cooler Master Hyper TX3 Evo and at idle my cpu sits around the mid 40s and at load while playing bf4 it sits at 57c which is good. How come my idle temp is a bit high but load temp is great?. I live in Australia so ambient room temp is around 29c. If I turn on my A/C it goes down to 37. Is there anyway I can get it to idle at a lower temp?. If I take my side cover off it lowers by 2 degrees but then i can hear fan noise and dust will get in. I have my case fans on full speed all the time and cpu on normal speed setting. Even putting it on performance mode which make its go faster the temp does not change. So any ideas?
