In available sources for the B99 HDXB99WFK4DGM processor the maximum temperature isn't specified. I am interested before acquisition of OEM of the version. Early faced AMD Athlon 64 X2 6000+ ADA6000CZBOX processor overheating :-(. I don't want problem repeating.

55°C, but as a 95w processor even with a mediocre HSF you shouldn't hit that unless you have an inadequate case and airflow.

As noted by black_zion, no one should have overheating issues with an OEM boxed processor HSF unless you have improper case airflow and it would need to be really bad for this to occur.

It's also important to be sure that you are reading the processor Core Temp, NOT the "CPU temp". The sticky at the top of the CPU section explains the difference between core temps - which is what AMD uses for the max 24/7 listed temp vs. the CPU temp which is a thermister temp reading below the CPU/APU socket and is no longer of any value since processors have internal temp readouts.

Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.

Thanks for information black_zion. 55C it isn't enough. I will better acquire the processor with bigger maximum temperature. For example Phenom II x4 945 HDX945WFGMBOX.

55C is the recommended max 24/7 temp. The true max temp is 70C. It's the same spec for both CPUs. None of the Deneb CPUs run particularly stable above 60C under full load. There is no reason why any Deneb based CPU would operate above the 55C 24/7 temp with normal OEM cooling.

 My OC'd Deneb 965 never ran close to 55C with modest cooling.

What exactly is your situation where you think that 55C is some thermal issue?

To me cases of overheating of AMD Athlon XP 2000+ AX2000DMT3C and AMD Athlon 64 X2 6000+ ADA6000CZBOX processors are known for. Therefore I want to avoid problems.

The B99 is not a 125w 90nm processor either.

As noted in my other responses, the OEM HSF is fine for any AMD CPU unless you have some case airflow issues. AMD actually tests these HSFs and knows that they keep the CPU within the desired maximum operating temp - unless you have some case airflow issue that needs to be addressed.

It's not unusual at all to find false or misleading technical information on the Internet. You should take all of this information with a large grain of salt.

It doesn't matter what the CPU/APU TDP is, the OEM HSF has sufficient cooling capacity to properly cool it. If you are actually having overheating issues then you need to find the real issue instead of condeming perfectly fine CPUs/APUs because you don't understand the cause of the overheating.

To be clear NONE of the AMD CPUs/APUs overheat with the OEM boxed HSF unless your PC has some airflow issue that needs to be resolved. Any normal, reasonable PC case and ambient conditions will not result in the CPU/APU overheating - regardless of some misinformed posts you might read online.
