CPU temps too high? (no, it's not because of the thermal paste)

My new PC's specs are as follows:


    AMD Athlon X4 CPU (stock heatsink)
    Kingston 1x4GB RAM
    MSI A88X-G43
    GTX750 (monitor at 1280x1024 and a TV at 1804x1014 to compensate for the overscan)
    2TB Hitachi HDD


When I power up the PC, the temp with Firefox and Steam open lingers at about 46C with the occasional jump to ~60C, according to Speccy. I know this is quite high but the PC operates fine so far. However, when I tried to play Minecraft, it shot up to 73C and steadily climbed to 80C, where I closed it to prevent overheating. Other than that, the game ran perfectly fine at 60fps.

What could be causing the high temps? I've already re-applied thermal paste and reseated the cooler and heatsink, and the PC is in a room at about room temperature, with neither side pressed against a wall. I've heard that the AMD stock cooler isn't great, but I don't think they'd sell something that brings a CPU up to 80C after 5 minutes of Minecraft. Is there anything else I can try other than just buying a new cooler? I really don't want to have to spend any more on one if I can get the PC to work fine without.

The stock cooler should be perfectly fine for that CPU and gaming. If it is working correctly, that is. Have you checked the fan's RPM?
Has this always been like this, or has this issue just started happening? Anything obstructing the fan blades? Can you post a pic of the inside of your case?

This issue with 3rd party programs displaying false high temps on these FM2 Athlons has been talked to death here:

If you don't feel like reading over 1300 posts, then just read this quick FAQ:
An Understanding of Temperature on AMD CPUs and APUs
Does HWMonitor say your CPU/APU temp is 70C when idling but your CPU socket feels cool to the touch? Is Core Temp only reading 10C but it's not possible because your room is 28C? The reason is that these and other 3rd party programs are not... See full content

The fan's RPM is around 2000. I can't take a pic right now as I don't have a decent camera but nothing is directly in front of any fan blades. It's been like this ever since I powered it up the first time.

Use the new version of AMD Overdrive and go by the Thermal Margin instead: http://www.techspot.com/downloads/4645-amd-overdrive.ht...

I guess that is kinda unclear. Room temperature is ~21C.

I reckon the game.amd site is still FUBAR? Whomever did that should be fired.

Exactly! Never fix something that ain't broke.

The thermal margins there still show 66C. It's showing me the same temps as Speccy, only it's updating faster.

EDIT: disregard that, I was reading the thermal margin wrong because I'm silly. Thanks, guys! :D

So, temps are normal?

They seem to be. Thermal margin shows 44C with Minecraft open. Is that about right?

Warmish, but safe.

Well, I've read that the AMD stock cooler is a bit poor anyway, so I can accept that as long as it's not scorching hot or anything.

When thermal margin gets to zero, the CPU will throttle from TCTL Trip until it is back in spec. 44C is plenty of margin :)

I was chasing a problem that didn't even exist. Live and learn, I guess :D

The stock cooler for that CPU is quite the worst I ever seen though. If you ever want to overclock that CPU then I would get a tower style heatpipe cooler (like Hyper 212).
