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 ?

My system spec is :


CPU: Intel i9 9900k
MB: Asus ROG Strix z390-F Gaming
Ram: Corsair Vengeance RGB DDR4 3000 MHz RAM - 32Gb (2x16)
GPU: MSI RTX 2080Ti Trio Gaming X
Cooler: Corsair H100i Pro Pro RGB AIO Water
M.2 SSD : Seagate 2tb Firecuda 510 M.2 NVME (boot O/S drive)
SSD 2 : Samsung 850 Evo 1tb
HDD : WD Black 3TbPSU: Corsair HX1000 Fully Modular
CASE: Corsair 780t WhiteFans : 3 x 140mm Corsair LED AF - 2 in front (intake), 1 in rear (exhaust) plus 2 x 120mm RGB Corsair on WC Radiator
OS: Win 10 Pro
Keyboard: Logitech G910 Orion Spark, Mouse : Logitech MX Master 3, Monitors : BenQ 27" 1440, Headphones : Razer Nuri Ultimate
 
Idle temperatures are not relevant and should remain unchanged as yours have. When overclocking you need to ensure your load temperatures are under control.
 
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).
 
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.
