Core temperatures too high?

[cloudymode]

I am using an E6300 running on the GigaByte DS3. I am doing a 50% overclock resulting in 2.8ghz. I have a ZALMAN 9500 paired with Arctic Silver 5, a 120mm exhaust fan, and 3 80mm fans throughout my case. However, CoreTemp reports my cpu on idle at 47-50c while EasyTune5 reports it about 37-39. Which temperatures should I trust and are these high? What can I do to lower these temperatures? I thought I had enough fans and hardware to run a cool system, but this does not seem to be the case Thanks for the help guys.

What's your room temperature? Core Temp's said to be the "most accurate" since it reads from a sensor inside the CPU.

not sure what the room temperature is...but yeah it is fairly hot right now haha I was wondering, how can I make my ZALMAN 9500 run at the highest rpm instead of constantly adjusting to the cpu temp?
