[SOLVED] First time overclocking and I cant get my max load temps under 80 Celsius

[bronsongivens]

Hi, I recently tried my first overclock but im worried that my temps are too high.

SPECS :

Motherboard :Asus Maximus X Hero
CPU : i7 8700k
CPU COOLER : NZXT Kraken x62 240M
PSU : 750W
RAM : 16 GB DDR4 3200
GPU : GTX 1080ti

I followed this video on how to OC : https://www.youtube.com/watch?v=pbRauc8gpQM


I need help getting temps down and maybe better OC settings

current oc settings 4.7Ghz

i ned help

one tip is to make sure to have good airflow and positive air pressure inside the case, ie more air being pushed into it than pushed out, even with an AIO. Keep in mind your GPU exhausting air as well as whatever other fans you've set to exhaust.

what's your case and how many fans? Plus, what are you using to test with - Prime 95 vs26.6, OCCT ?

That 40C temperature does seem very high at idle. You should be idling at around 30C with that 4.7 Ghz.

Another thing I notice is your vcore in cpuz, which is already set at 1.36V. It really shouldn't be that high given that it's only a 4.7 Ghz overclock. While each chip's overclocking capability is different, you shouldn't see vcore of 1.36 with just 4.7 Ghz (all cores), that's way too high.

I think you should go to your BIOS and adjust your vcore down to around 1.2~1.25 and see if your computer can boot up. Once it does, do prime 26.6 test again. In short, you're trying to find the minimum AND stable vcore for whichever frequency you choose.

im using cinebench and now looking into prime95. the core temps above are from one cinebench test.
Im using the NZXT S340 case with 2 standard case fans and my gpu has three fans on it. and my cooler is the nzxt kraken x62 with two 240mm fans on it

this is after i dropped the vcore and changed some settings on overclock.

though i dont think these temps will stay throughout the day.

I have pretty much the same setup..At 4.9GHz, I need 1.278v which is roughly where you should be able to get to. In fact 4.8GHz should require even less vcore. As bronsongivens has said, start at a certain speed like 4.7GHz at say 1.25v and find the absolute lowest vcore that you can get stable for the speed....Then work your way upwards with the next step being 4/.8GHz and then finding the minimum vcore for that. Test with Prime95 version 26.6 and to start with the blend test as small FFT's is never going to be a punishment that your CPU is going to take...

Also remember LLC plays into the stability for any overclock...Not sure on ASUS settings as I use a Gigabyte board and also the Offset/Addaptive mode...

You idle temps should always be in the low 30's and overclocked memory XMP above 3000MHz can make that a little bit higher...

Don't FORGET THAT YOU CAN SET DIFFERENT FAN CURVE SPEEDS IN YOUR COOLER TOO .I always make mine aggressive.

with only two case fans, you've got one fan (unrestricted) exhausting air and the GPU exhausting air
while the front case fan is blowing air in, it's somewhat restricted - it's restricted by having to pull air thru a filter and what looks like a 1.5" vent opening at the top (with probably a similiar opening at the bottom) and also by the fact it's blowing that air straight at the HDD cage approx 1" in front of it which means a good deal of airflow is lost to turbulence.

In addition to the suggestions other posters have made, i'd add another fan blowing in. For the hey of it pull the front panel off and see what happens to your temps
