8700K idle/load times out the box clocking.

[Adam Needham]

Putting this here since I am not exactly overclocking.

Currently running my entire PC at stock, whatever they came out the box at, is what they stay at, too scared and cheap to change that. But recently, say start of the year, I noticed my CPU temps went up.
Right now I idle anywhere between 35-50c and under load get around 60 average to about 70 max.

My questions are; is this normal/safe? What do you need to know?

MB: Asus ROG Strix z370
CPU: I7 8700K 3.7ghZ
Cooler: Kraken x62 AIO Running 4 fans on it, all pulling air out of the case.
Got 3 140m Noctua fans

I should say by idle I mean a few browser tabs open, researching things and such, so maybe that has something to do with it.

In regards to airflow; I have 3x 140 noctua 2000rpm taking air in, 2 from the front and 1 from the back right by the RAD/pump and then the 4x noctua 2000rpm taking the air out over the RAD. All in a Corsair 750D which has pretty decent airflow. GPU is normally fine so I will have to try that as you said, I am going to see if I did actually put too much paste on as some have suggested elsewhere while checking my backplate too.

Don't forget you still need to maintain decent case airflow, so you need both in and out fans. Ideally, fans on one side going in one direction and fans on the other side in the opposite direction. As for paste, too much paste is a myth, the pressure of the mounting bracket squeezes out any excess. It does make a mess though! It could, however, be worth redoing it, just in-case you created a void or something.

I read somewhere that people have fans going both directions on their RAD, which gives the benefit of both, though it would mess with the airflow a little and just recycle that air, though works for some cases. Going to try and have the PC on load for a few hours and then see how long it takes to cool down, apparently if it takes a little too long that could be an issue with the pump or the unit all together.

Just to Polish this off, I turned off turbo boost and dropped 10c.. turns out it was just boosting my voltage from 1.08v to 1.24v

But then you are stuck at the 3.7Ghz baseclock, aka lower performance.

I don't really need much more currently, most pressing thing my PC handles is VR and even then that doesn't take much.

are you suing the nzxt cam software on the pc and using the adaptive pump speed based on temp/usage?

the temp look completly nromal for a i7 8700k and if you are going on about idle temps atm in kiddermisnter its been very hot now for 2 weeks and in my house the temps are really getting high i wouldn't be suprised if the temp around the computer is not much below 35 degress

Currently got Cam monitoring the CPU temp itself and not the liquid temp. My room is pretty damn cold compared to the rest of the house, so the temp jump was out of the blue.
