Hi there. I have noticed that my computer has lost performance lately. It is an old Intel Core 2 Duo E6600 with 2.40 GHz. I used to run some games quite well, with graphics in the middle to high settings. I have also a GTX 650 with 1MB and 8GB RAM. Using Windows 8.1 Pro.

I know that it is not a good configuration for nowadays games. But I am talking about games from 2010, 2011. They ran very good before. Now, I notice this low performance for some games that I ran before.

I then started to look for any kind of problems. First I noticed that, in some cases, the CPU won't use more than 35% and 45% (at least that's what I noticed). In the windows resource monitor, it shows that the CPU only gets a 65% of maximum frequency.
Then I checked the Award BIOS to see if any value for the CPU was set wrong or inappropriately. . What I saw there shocked me. The CPU temp was showing 83°C and the Current System temp was in 39°C.

I decided to run some CPU temp monitoring software. First I tried ThrottleStop. It showed that the 2 cores are varying in temperature. During a TS Bench, one core went to -28°C and the other one to 95°C. After the benchmark, both cores went back to something between 85°C to 89°C. The SpeedFan software, in the other hand, shows a temp range for the cores of 60°C to 65°C.
All the fans are working fine. The fan 1 is reporting 2744 RPM and the fan 2 1313 RPM. I don't know which fan is which. But I have the CPU fan and a case fan.

So, who might help clarify my doubt. Could be some problem with the CPU and it is going to failure in some shortly future? Is there a problem that is causing the heating of the CPU?
BTW, I didn't do any overclocking. Left the BIOS setting in its default.

Thank you.

Here are some screenshots of both programs.

Use CoreTemp for Intel it's usually pretty accurate. If you haven't already dust and blow out the internals of your case. Make sure your CPU cooler is clear of any dust bunnies. If this does not help, you will need to remove the cooler and clean properly. Remove all thermal paste and reapply some quality paste. This should cure the problem unless the CPU has been running very hot and has become damaged but this is quite unlikely. If it has though you can buy Core2Duo's for buttons on ebay. I would advise an upgrade to a core2quad if your system board supports it because they are still surprisingly capable processors.

Poprin, thank you for your help. Indeed it is a little dusty in my case. Might be the problem. My board does support a Core 2 Quad Extreme. But I think, for that price, is better a I7 instead. Don't you think?

Here are some screenshot of CoreTemp. Strange that both cores aren't getting to high. I had a peak of 75°C for both cores when running Steam. For that I didn't ger a screenshot.

The TJ MAX is the maximum temp recommended? Strange because on Intel's website, for this processor, the maximum recommended is 60ºC.

One strange think I noticed (I might be wrong), is that the freq doesn't go up in any circumstance (ilde or running a game).

Skyvolt that will be the recommended running temp for that CPU, if it is running at 75c then it is running too hot and you are experiencing thermal throttling. This is where the CPU reduces it's clock speed and voltage to protect itself because it is running too hot. This is what is causing the performance degradation. You need to get your CPU below 60c even at full load.
