Hello everyone. While gaming today I noticed that my CPU, an AMD A10 5800K, was reaching 70°C, which is alarming considering my computer will shutdown when the CPU reaches 74°C. Normally it never goes beyond 64°C under heavy load. I noticed that the fan speed was only 3,400 RPM when the CPU was running really hot. My question is, what is the maximum fan speed for the stock AMD cooler packaged with the AMD A10 5800K? I seem to recall seeing the CPU fan speed at around 6,000 RPM under load in the past, but I could be wrong. I don't mind if the fan is loud, I just want to make sure my CPU doesn't overheat.

I am not overclocking the CPU and I replaced the stock thermal pad with Arctic Silver 5 thermal compound about 6 months ago. I also recently cleaned the dust from the inside of my computer so it is nice and clean inside. I checked my BIOS settings (my motherboard is an ASRock FM2A75M-DGS) and I set the CPU fan to "Full On", but that didn't seem to do anything. The BIOS firmware is up to date, as are all the drivers for the motherboard. I guess I should also mention that I am not using the CPU as an APU as I have an MSI R9 270 installed for gaming, so the integrated graphics are disabled.

Any help you can provide is greatly appreciated. Thank you!

Here's a quick update: I tested my computer with the same scenario (playing the same game in the same area) and this time my CPU fan was spinning at 6,200 RPM and the CPU was staying between 64°C and 67°C. I'm not really sure why the fan wasn't spinning very fast when it was at 70°C. This is after I changed the BIOS setting for the CPU fan from automatic to "Full On". Maybe that was the problem; I'm not sure.

firstly, your Stock CPU cooler may be having it's last days at cooling the CPU, as it clearly isn't doing it's job very well. That said 70 degrees is not damaging, nor will it effect the CPU in any way, it is within operating temperature and can run at this temp, it should not also shut down at 74 degrees, it should however at 90+ degrees.

I suggest spending $30 on a cooler master hyper 212 EVO, best CPU cooler for the price.

You were correct - 6000 RPM is about the max for the stock fan. This can always vary by about 10-15%.

The thing about keeping an eye on CPU temperatures is very tricky. Especially since there are two sets of temperature readings: The CPU Core and the CPU Socket.

The CPU Socket is on the motherboard, and is great for idle temperatures, however, given the space of it from the CPU, it reads load temperatures at higher, by about 5-15C.

CPU Core readings are corrected to provide accurate temperature when at load, however, the offset makes them innaccurate when idling.

So, you now get to embark on the wonderful adventure of trying out multiple temperature monitoring programs to see which set is actually which. This is particularly fun with APUs, since they can have an issue with temperature monitoring programs. It could be that your CPU is actually getting to just above 50C.

If you're still using a Radeon GPU, AMD Overdrive may work. I have good luck with CoreTemp as well.

Thank you all for your replies. I am sorry for my late response. My computer is exhibiting other symptoms like randomly powering off under load and during idle so I think the problem may be more involved than I originally thought. I will look into those other temperature monitoring programs to receive a more accurate temperature reading for the CPU.
