Pretty bad overheating issues.

So basically I built my new PC a couple of months ago and it has always ran very, very hot. I have an FX-8350 and after looking into it I found that the stock CPU fan is less than adequate for it so I chose a far better quality fan and heatsink for it: The Cooler Master Hyper 212 EVO. Although it quickly became apparent that my temperatures were worryingly high, right now it is running at 66c (or 151 Fahrenheit). Surprisingly though this system never complains it doesn't shut or slow down erratically. But the temperatures are no error I accidentally touched the heatsink after ten minutes of it being on and I suddenly began to understand what it would be like to live in Pompeii in 79AD.

As it stands the system has one intake fan at the bottom front of the unit and no exhaust fans (if one were in place it would be directly next to the CPU heatsink). So my question is under my limited budget would it make a considerable difference installing a rear exhaust fan or would I be better looking for alternative solutions such as closed-loop water coolers? Another possibility is that it is just bad thermal paste or something silly that I have missed. Any ideas?

System specs (just for fun):
- Processor: AMD FX(tm)-8350 Eight-Core Processor (8 CPUs), ~4.0GHz
- Memory: 16384MB RAM (DDR3 1833MHz)
- Video card: NVIDIA GeForce GTX 750 Ti (2GB GDDR5 ver)
 
Your situation is likely due to having nowhere for the hot air to travel.
I would invest in an exhaust fan, and the best place for it would be right next to your EVO. Have the evo blow air across the heatsink straight into the exhaust fan, least amount of time possible.
Thermal paste could be an issue, but I doubt it given the current situation.

Also, what are you using to check temps?

Thank you for your quick response. I am using SpeedFan and CPUID's HWMONITOR both report extraordinarily high CPU temperatures. The reason I am a tad reluctant to simply use an exhaust fan is because my PC literally heats my room to the point were I no longer require a radiator. In that case will the fan actually assist in dissipating the heat or am I just blasting a load of hot air around my room still? Also are there any specific case fan models that are good at shifting plenty of air away from the case?

**Important thing that I forgot**
The case also has a fan on the side panel window

As Gam3r01 mentioned, exhaust fan is a must, with heatsink fan blowing hot air towards the exhaust fan (see image below). Buy a good exhaust fan (they are not expensive) with the maximum size that your case can accomodate (usually 92 or 120 mm).

If you mount the fan at the rear, see "B", if it's on top, use "C".

If your room (ambient) temps are already high, then the CPU temps will be higher than normal. CPUs are hot, and starting with hotter then normal air won't help any. If you only have one case fan pulling air in I agree that an exhaust fan might help. But you need to cool your room some as well.
