I have an i9-11900K with a Noctua NH-D15 and a ASUS ROG Strix Z590-E motherboard. I'm curious what a good temperature range for this setup is both idle and under load. When idling in Fan Standard mode (1-5%) My Core temps average ~40-42C. When I turn the fans to Full Speed and run the CPU-Z benchmark, the motherboard throttles down the 4.8GHz and never gets above 72C (averaging around 66-70C per core). First, is this a good range for 100% load at 4.8 GHz? Second, how come the system is throttling me down from 5.2GHz? AFAIK 70C isn't a problem at all and even 80C at 100% would be perfectly fine. What sort of temps should I have at 5.2GHz and 100% load with this CPU fan? Thanks! #1 · Apr 28, 2021 I have an i9-11900K with a Noctua NH-D15 and a ASUS ROG Strix Z590-E motherboard.

Turn on adaptive boost and enable Asus multicore enhancement (remove all limits). This should boost you to at least 5.0 all core. Next you need to make sure you unlock the processor so it uses more than 125w. I think this is already on by default with the latest bios. Then watch the temperature slowly rise to 90 Celsius when stress testing. Make sure you use Gear 1. I think it supports up to 3733 MHz? Can't remember exactly. So if you have ram rated equal or below turn on XMP and set it to Gear 1. Also worth disabling C states as it gave me perf boost in Cinebench and gave me better overall GPU utilization in Timespy. #4 · Apr 28, 2021 Even with the Noctua, the temps will hit 90 under 100% load at 5.2GHz? That doesn't seem right...? Show more replies 0 Reply #3 · Apr 28, 2021 We would need to see a reading of power consumption and voltage. Case, fans and their configuration have a big impact kn temps aswell. The numbers you posted dont look bad, but they're nothing to brag about. Sent from my Redmi K20 Pro using Tapatalk #5 · Apr 28, 2021 Understood; but was curious, with a properly installed Noctua and fan control configuration, what temperature threshold should I never exceed even under 100% load at 5.2GHz? (e.g. 81C) 0 Reply #7 · Apr 28, 2021 You want to ideally stay under 90c for heavy full-usage and 100c is absolute max before you get into trouble area. For full boost function you'll want to keep under 70c, that's what the boost/thermals were designed to run under. These and 10th gen are hot, fiery, and can be difficult to control unless you use the thermal features (TVB) and power limits. #8 · Apr 29, 2021

Seem kinda warm, but not terrible. What is air temp entering cooler during tests? Air temp entering cooler of 2-3c warmer than room is about as good as it gets. If it's much more than that I suggest adjusting case fan speed, placement, or possibly getting better case fans that will supply air no more than 2-3c warmer than room. Every degree warmer air entering cooler is becomes same degree hotter component is (at same load & fan speed). So if air entering cooler a few minutes into testing is 12-13c warmer than room and case airflow is improved bring it down to 2-3c warmer your CPU temp will drop 10c .. same as air temp drop is 10c.

#9 · Apr 30, 2021 (Edited) your CPU temp is normal and fine besides if you don't feel hot air coming out of your system there's nothing to worry about #10 · Apr 30, 2021

if you don't feel warm air coming out, it is staying in the case. That is, in fact, a problem. 1 Reply #11 · Apr 30, 2021 What ciarlatano said. Checking cooling system by "feeling warm air" is a joke. #14 · May 5, 2021

I have an i9 9900KS that runs at 5GHz full time, my cooler is the Noctua NH-D15S with only one fan. At idle temps are from 28 to 30 degrees C, with a more aggressive fan curve than your 1-5%, can't remember what I have it set at in BIOS for idle temps. I just tested using CPU-Z, temps ranged from 69 degrees C to 76 degrees C on the hottest core, room temp 23.3 degrees C [74 degrees F]. Note that my CPU runs a little hotter than it did when it was new. You will not see much more FPS in games at 5.2GHz vs 5.0GHz if that is why you want to overclock. Silicon lottery is finicky, most CPUs will not hit 5.2GHz and most that do get extremely hot, even with a good cooler, because of increased voltage. My CPU was able to hit 5.2GHz, couldn't quite get 5.3GHz, I think I was able to get it to 5.29GHz. That was when it was new, however I was using a smaller Noctua NH-U14S that I pulled off of my old i7 7700K. At 5.2GHz+ using the smaller cooler maximum temps were 100 degrees C using IntelBurnTestV2. Also, after about a year remove the old thermal compound and replace with a good TIM. The Intel CPU IHS will warp over time because of heat and the TIM that is now on the CPU will not be able to cover the gaps and hot spots will develop. EDIT: I forgot to mention that my GPU is an MSI RTX 3090 SUPRIM X that puts a massive amount of heat in my case, so take that into consideration. #15 · Jun 17, 2021 I struggle to keep my 10700k cool at 4.9ghz when my cpu is going full bore with a NH-D14. You’ll definitely have temps in the 90s at least with that combo running something like cinebench. Gaming will run much cooler though, as it won’t stress the cpu 100%. #16 · Jun 17, 2021 Have been running three 10900Ks with Arctic AIOs. No problems running at their speeds above 4.9Ghz. In fact some of them can sit at 5.3Ghz for several minutes whilst doing their video editing. Air cooling would be a waste of time when using the 10900K at its full speed, for prolonged periods. Will only use the current Arctic AIOs for that alone. 1 Reply Insert Quotes Post Reply
