Overheating i7 4790k?

Question

MSI

Overheating 4790k, and idle. After starting the computer, literally in 20 seconds the temperature reaches 95 degrees. In the BIOS, the same thing - immediately after starting the processor starts to heat up quickly as well.
At first I sinned on thermal paste, changed it, the result is the same. Then I thought maybe the water block did not fit snugly to the processor, removed it, changed the thermal paste again, carefully installed it - the result was zero.
The processor did not drive, the settings are by default. True, the BIOS sets the input voltage to the processor ~ 1.7
Hardware:
i7 4790k
MSI Gaming 5
Deepcool Maelstrom 240
I'm starting to think that the pump in the pump is dead, but I don't know how to check.
It could be that the bios is setting the cpu settings wrong.
Please suggest something)

Answer 2

And touch the water block with your fingers, is the radiator warm?
