You're seeing fluctuating speeds like 4.17GHz and 4.18GHz in Task Manager because the CPU is being detected by Windows as being under load or stress. This can happen if your system is handling intensive tasks, background processes, or thermal throttling. It doesn't necessarily mean your CPU is faulty—just a normal response to workload.
Don't stress over hitting that 4.2Ghz figure—it's just the main core boost speed. They note it varies based on several factors like the motherboard, your actions, and temperatures. A 30Mhz gap with 10Mhz changes isn't something to worry about.
It will enhance its performance timing if possible, based on your hardware and heat conditions
