Yes. It's normal for Intel chips when you push hard on the 14nm processors.
2 reasons.
It's running on 70% of 1250 rpm fans.
I didn't apply new thermal paste.
I took out my AIO from Skylake i7, I saw some residue paste there, I just fixed it on Coffee Lake.
I was lazy to apply new thermal paste because it was 3am in the morning when I installed the new processor and mobo.

I'm waiting for new grizzly thermal paste and delid kit.
Then only I'll apply new thermal paste.

P/S 4.8GHz @ 1.3v is the sweetest spot. With low rpm fan setup and old thermal paste, temperature doesn't go beyond 65c in games.

Congrats on your purchase, welcome to Coffee Lake club.

Is that your best vCore or can it go lower?
Did you notice any vdroop (load voltage drops too much from BIOS set)?
What's your vCore set in the UEFI BIOS, CPU-Z idle and load?

P/S: I'm also waiting for my 8700K from Active Lancing biggrin.gif

Yes, I think this is the best vcore.
There is an error in OCCT when I lower than 1.3v @ 4.8GHz.

I set 1.3v in bios.
The core voltage reading on CPU-Z is 1.288v under load.

I got my 8700K from Active Lansing last Wednesday. thumbup.gif

What Prime95 version are you using?

v26.6 and below have no AVX/FMA3 instruction
v27.9 has less stressful AVX, no FMA3
v28.5 and newer has stressful AVX+FMA3

Edit: I can see FMA3 in your SS so should be one of the latest versions.
Your CPU core temps look great.

Officially jump on the bandwagon...

ROG Maximus X Apex and TUF Z370-Pro Gaming are here.

Let's start with the Apex rclxm9.gif

First thing to do is of course to overclock the i5-8600K CPU to 5.0GHz (BIOS set 1.425v, LLC5) and run Cinebench R15:

CPU score: 1221 cb (7700K @ 5.0GHz: 1087 cb)

Currently, I am also testing the LLC in Realbench 2.44 (AVX) to see the vdroop/vdrop. This is just part of the results:

LLC works fine for me, vdroop = -0.016v, despite ROG Strix Z370-F users are complaining about 0.08-0.09v vdroop.

Also note the core temps, idle @ 57.3C, load @ 85.3C, which are in my opinion a bit on the high side.
Cooling is custom loop lowered by a pair of 360mm radiators in push-pull fan configuration.
