High temperatures for an i7 8700K?

I just put together an i7 8700K on a Taichi z370 with Arctic Silver High-Density Polysynthetic paste and a Noctua NH-L9i 92mm fan. When I first booted it up, the fan worked fine and I went to my BIOS to do my boot sequence. My CPU temperature was 51-52 degrees Celsius even when I put the fan at full speed it stayed over 50 and up. I know I put enough paste on and the fan on correctly so is this normal for this CPU with no load and a pretty good fan on full blast?

I don't know how surefire the sensor is on an original BIOS Taichi but it can't be that off. I feel that's too high but don't understand why, anyone else have these temperatures under no load with an 8700K?

What is your load temps, idle is not important too much.
I haven't booted it up yet since I did a basic Windows 10 installation. I'm worried about the temperatures, 52 degrees on the BIOS screen can't be good.

Is a stock BIOS cpu temp sensor accurate?

Ok, Rygu my friend. Let us sort this out for you. Firstly its ok that the BIOS is showing 52c. The reason for this is when you enter BIOS your CPU starts working and if you stay in the BIOS you will notice temp keeps going up and up,, like almost full load. Give us temps from within Windows. If idle is 52 then the full load is going to be really high.

You can use hardware monitor in windows.

For example :

This worked, thanks to both of you. Now it's only showing 36-37 degrees at idle. That's a lot of stress relief on a brand new build, I appreciate the help.
