Is my CPU running too hot? (over 60°C)

I have been recently getting buzzing noises from my PC while gaming or doing other intense things. It is almost certainly coming from the speaker as if it is warning me of something, because it is very loud, and not at all coil whine.

I never knew what was causing this buzzing. But today I was updating my Windows Experience Index for my new GTX 760 (the buzzing happened before I got this though) and it started buzzing. At this point it hit me that it must not be the graphics card, and may be the CPU or something.

I remembered in the BIOS I saw a setting which said something like: "CPU warning temp" which was set to 60°C. I then realised that it may well be the CPU getting too hot.

I installed HWMonitor, and launched Battlefield 3. After a few minutes, the buzzing started. I closed the game and quickly checked the temps. Sure enough, the CPU's cores were around 67°C each when I caught it, and may have been rising above that. I waited until they cooled completely and took note that my CPU was around 40°C idle.

So I think the buzzing is the motherboard warning me that the CPU is too hot. But my questions start here. Is it really too hot for an i5 CPU? Should I buy a new heatsink ASAP or either remove the speaker or raise the warning temp? Would this be the sole cause of the buzzing, or is it something else?

Some more info:

- I have NOT overclocked the processor at all, just installed it right out the box and haven't touched it since. Why on Earth is it overheating if I'm not even overclocking?

- I only built this PC back in December, so there is no way there will be an outstanding congregation of dust in the heatsink. I will take a look anyway.

- My case (Cooler Master Elite 430) has decent airflow and I have one intake case fan at the front, and one exhaust at the rear.

- The buzzing hasn't been around for a long while, but has started again in the last few days. Bear in mind that I believe this is because I am British and we are currently in a massive heatwave. It is much hotter than any other summer for an extremely long time here, and my room temperature got to 32 degrees today. This furthers my point of temperature being the cause.

What do you guys think? If I need to upgrade the heatsink, I will be getting a Hyper Master EVO 212:

Sorry for the very long post, but I wanted to include everything so I can sort this out sooner rather than later.

Thanks a lot for the support!

Open the side of the case, turn on the computer, wait for the buzzing, and try to locate where it is coming from.

Also, your temps are fine. Ivy Bridge's TJ Max is 105C. Obviously, you don't want to get near that, though.

Best solution

Your temps seem a bit high. Check the following:

- ambient temp vs idle temp vs cpu load temp (using prime95 after 20min) vs gpu load temp (after 10min). 67C with only gaming test (battlefield3) seems high @ stock clock because cpu load test (prime95, intel burn) will stress cpu more and cause higher core temps. Try again with prime95 and see the max temp.

- tCM elite 430 has many possible fan setup, and does make 2~5C difference depending on fan setup. leave the side panel open to check the difference. ry and see the difference cpu load temp between open side panel vs. closed.

- It is possible that the oem heatsink isn't installed properly, so try to seat it again. Just remember CM Hyper212 will improve the temps ALOT. I would get it and OC the cpu to about 4ghz minimum. You will get lower temps + better performance.
