Every other component is running under 40c on idle except for the CPU, which varies between 60-80c, but mostly around 70c.

My CPU is an Athlon X4 760k and I'm using the stock cooler. I'm assuming the problem here is the heatsink, but again, it's not making any noise at all. Could it just be the thermal paste? Could it have dried in the box before I installed it?

How fast is the fan running? What case and mobo are you using? The Temps should never be that high when idle. There's something wrong with your cooling. The Heat sink might not be placed correctly or not creating enough contact. Bad thermal paste could also be the problem. I would suggest replacing your thermal pace to improve temps and getting a cheap aftermarket cooler is always a good idea even if you're not overclocking.

So, I just checked, and it was definitely the thermal paste. It was all dried up and scattered. I re-applied the thermal paste and made sure that the heatsink was making enough contact.

When I restarted the PC it was at ~40c for around 10 seconds, but then the temp just started going all over the place. From 35c to 70c on idle. I installed programs with Ninite and it was running on an average of 65c. Now that that's done, it's roaming around 44c-53c.

I wanted to see if it was maybe my heater but I turned it off completely for 10 minutes and the temps did not change. What could be causing this?

This is my build: http://ca.pcpartpicker.com/p/2siTR

Everything's stock.

Also, I tried opening 5 YouTube videos at the same time, and the temperature never went past 70c, but was hovering around 65c. Idle temperature is around 43c now and never goes any lower. Heatsink fan still not making any noise at all no matter what the temperature is. Seriously, what is going on?

Ok, so... apparently, now, nothing gets my CPU hot and there's barely any usage.

Ran Fallout: New Vegas on ultra settings in 1050p and the temperature stayed at 45c the whole time and the CPU usage the whole time did not go past 5%.

I know FNV isn't intense on hardware, but still... is this normal at all? Is my CPU having a giggle?
