It might just be a faulty temperature sensor.
Start windows Task Manager and run a program that should use all four cores.
The Cpu Usage History windows for each cpu core should show activity for each core that is running.
The lower right portion of the window shows "Active Core Count = 1"
Run a stress test such as Prime95 for 10 minutes and see if core #4's temperature rises.

i restart pc twice . seem to work with stress .
Clearly the core is not dead, thank goodness. The Intel ETU is good in many ways, but the temperature and CPU speed monitoring seems to be slow at times. The CPU does not use the core temps for protection purposes, just the single overall CPU temp, which is fine according to your screenshot.
The temp sensor of core 4 may be "stuck", and won't provide any temp data when the core is cool. The temp sensor on Intel chipsets, like a P67, Z77, etc, won't even show a temp reading below a certain value. A Z77 won't show a temp lower than 43C, and others I've had on older boards start at 50C.
As Prof Jim said, try another monitoring program and see what you get for core 4's temp.
Is this a new system and you are seeing the bad core temp for the first time, or did it just start doing this?
