CPU temperature too high

[Murena]

Hello,
I have a message "CPU fan error" when starting the PC. This message is not blocked by pressing F1, I can continue.But when the PC is started I note with Asus Probe 2, the temperature is 92 ° C which seems a lot.The temperature of 92 ° is stable it will hardly move.
The fan speed is around 2812 RPM, and it does not move much either. The fan is running well, I checked The CPU usage does not exceed 10%.

I cleaned the sink which was filled with dust and the fan. Despite the cleanup, the message continues to appear.
Rest of the configuration:
Asus P5B
Physical Processor / 2 Cores / 2 Logical Processors / 64 bits
Intel (R) Core (TM) 2 CPU 6400@2.13GHz

My question is: 92 ° C is it too much? What can prevent the temperature decrease?

Thank you for your help

Hi, Yes, it is clearly too high as temperature.Use thermal paste, There are many of the thermal paste between Processor and ventilation Fan ?

I finally watched the CPU temperature following the message of the bios. Otherwise I had no symptoms.I have changed my power supply (better than the original).But I do not see a new power supply would heat the beast too much ...

The radbox, the cooling system Intel house. The thermal paste is not as fast volatilizes: it Recheck the assembly
