Question Temperatures for an i5 8600k with a kraken x62

[c0mmitted1098]

I'm a bit new to building PC's I've built my own, my sisters and helped a mate. I recently decided to upgrade from my CPU cooler which was a pretty standard air cooler to an nzxt kraken x62 for my i5 8600k overclocked to 5ghz. I was wondering what sort of temps I should be expecting because they've jumped a fair bit since I first put the cooler in and I can't figure out why.

Specs are:
Asus prime z370 A
16gb 8x2 ddr4 3200hz gskill trident z
Asus ROG Strix 1070ti
I5 8600k clocked to 5ghz
NZXT Kraken x62

All inside an Nzxt h500

At the moment I'm getting between 30 and 40 C idle temps which is concerning but not exceeding 65C at 100% load.

Are these good temps or not because looking at other sources online I really can't tell.

Temps are safe but could be bit lower. Did you set the mode to performance in the software? You might want to reapply thermal paste

I've got it set to silent mode on on the pump and fans. I did change then to performance but not a whole lot changed after playing rainbow for a couple hours. It just turned my pc into a jet plane. But I'll give reapplying thermal paste a go and see if that helps.
