hi,
my problem is that temperature #4 is way hotter than the rest.
when i turn on any game that is cpu based its lagging as hell.
for example: apex legends is not working at all, but i can run cyberpunk2077 on ultra and its ok
what can i do to solve this problem?

You're reaching the limits of your CPU by the looks of it, some game code gets heavier with updates and 6 cores with no hyperthreading might just be the limiting factor nowadays.

That said, a repaste and remount of the cooler would seem like the first thing to do here. That might just solve it for now.

That's bloody Open Hardware Monitor, isn't it? Please stop using that app and use hwinfo instead.
What you've highlighted is an unspecified motherboard sensor. Seeing how 'naked' Asrock Z390 Pro4 is, it's probably a VRM sensor.
It's hot, but not enough to throttle core clocks, from the looks of it; core clocks are at 3.9ghz.

The actual core temperatures are several lines down from what you posted:
| +- CPU Core #1 : 45 44 49 (/intelcpu/0/temperature/0)
| +- CPU Core #2 : 44 44 50 (/intelcpu/0/temperature/1)
| +- CPU Core #3 : 47 46 52 (/intelcpu/0/temperature/2)
| +- CPU Core #4 : 47 45 50 (/intelcpu/0/temperature/3)
| +- CPU Core #5 : 44 44 50 (/intelcpu/0/temperature/4)
| +- CPU Core #6 : 44 44 51 (/intelcpu/0/temperature/5)

my laptop have two cores which constantly reaches 95+ while the other two cores are fairly cool at ~80. I even suspected the stock thermal paste didn’t touch the other two cores. When I repasted with a Thermalgrizzly kryonaut apparently there’s plenty of paste and temps only improved a few degrees.

So unless the OP’s CPU have a defective IHS I can’t explain if a way to explain.
