i9 9900k first time overclock

Hi all,

I have just done a first time overclock on my new rig. I have used the Asus Rog AI utility followed by tweaking with the Asus Intel Extreme utility.

My old idle temps were :

My new ones are :

CPU-Z shows :

Does that seem OK or should I back things off ?

Idle temperatures are not relevant and should remain unchanged as yours have. When overclocking you need to ensure your load temperatures are under control.

Under load the temps are approaching 80 degrees - I think that is far too hot isn't it ?

You are looking to keep the CPU under 85c under stress testing conditions, this will make sure that temperatures are well under control in 24/7 use.

Ok i've done some more tests. Stress testing peaks at about 80c - Normal day to day use (lots of browser tabs, code editors, ftp software, slack, skype all running) shows about 38-40c - Playing Shadow Of The Tomb Raider the temps average around 40-50 - Now and again 60 - But this last sessions (measured with coretemp) of about 7 hours of coding, broswsing and gaming the max it hit was 74. Is this safe to work with or should I return to stock - I'm currently at 4897Mhz ? (BTW - It's a really hot day today).

I'd be perfectly happy with those temperatures.

Snowy2012 · 24 Jun 2020 at 21:49

Actually, normal day to day use as above is prob 40-50c - Is that still OK ?

PieEater · 24 Jun 2020 at 21:53

Yes, absolutely fine, your cooler seems to be doing a good job :cool:

Snowy2012 · 24 Jun 2020 at 22:18

Thanks for that

I think maybe the case helps as well - It's a Corsair 780t with two 140mm fans pulling on the front and one 140mm pushing at the back. The rad is mounted horizontally on the top of the case with 2 fans on it.

I have the Corsair rgb headphone stand and I have it set in iCue to go from green to yellow to red as temps increase - At stock it never really moves from green. Overclocked it hovers between green and yellow and goes into red under stress - I guess it's the physcological effect of the colours that got me worried LOL!

You should be able to change the settings so iCue has a more reasonable temperature range. By default they are probably using a one size fits all approach which is never going to be appropriate for every scenario.

Tried some Metro today and temps hitting between 60 and 70 when gaming - Max for the day is 75 - And it's really hot here today.

Snowy2012 · 28 Jun 2020 at 23:21

I ran realbench stress test today for an hour and temps hit a max of 87 - Is that acceptable ?
