can some one plzz tell me my cpu is normal or overheating???
it always remain 100degree C..!
According to your screenshot it is not at 100c...
TjMax is the maximum safe temperature for the chip...
but if you look at the core temps it's only running in the 60s...
A little math TjMax - actual == 40c so you have a fair margin.
Granted I would never let a chip run that hot but it's not disastrous unless it gets way hotter under load.
Some things to try....
1) Clean all your heatsinks
Get a can of compressed air (available at most computer and electronics shops) and blast all the dust out of everything.
2) Clean all your fans
Dust on fan blades can seriously degrade their perfomance. A 1" paint brush usually does the trick here.
3) Improve the airflow in your case
Add a couple of extra fans. The ones at the back should blow air out of the case. Top fans should blow air out. Front and side fans should blow air in.
4) Investigate a better heat sink.
The stock coolers provided with most CPUs are adequate for general use but if you are gaming or running complex programs that keep the CPU really busy you may want a better cooler to get the extra heat off that chip.
