11900K High Temps at 4.8ghz! Help?

[Dartix]

So I'm trying to run my i9 11900k at 4.8Ghz All Core 1.25v but my temps are around 75-80°c, peaking up to 90°c

I have a Noctua NH-D15 which I installed, so I thought my temps would be way lower, I also have 3 exhaust fans so is these temps normal?

 

I want to get the best performance out of my cpu while maintaining good temps, so does anyone have any recommendations? Have I done anything wrong? Are my temps normal? And if not what should I do, or what should I put my All Core Clock and Voltage at etc.

 

Any advice/help would be appreciated as I just installed this new i9, as my new cpu so I am new to overlooking cpus as I had an i5 10600kf before which I used mostly stock.

 

Thanks.

I dont think there is anything wrong there as 10,11 and 12th gen CPUs are all very power hungry and inefficient. What is the CPU power consumption under load?

[BiotechBen]

Unless you wanna go liquid cooled, comet lake(10thgen), rocket lake(11th gen), and alder lake(12th gen) all run  hot; very hot for rocket and comet.

Welcome to big 14nm CPUs? It's the heat of more than 2 6700Ks under there, hot should be expected. You coul try optimize the voltage as if you're overclocking, but that's about it without going liquid cooling

Usually around 100-110W

What voltage would you recommend and what All Core Clock for the cpu?

 

I have no plans for water cooling as I bought the Noctua for £100 and I'm just not wanting liquid cooling.

So would you say peaks of 90°c and usual temps of 70-85°c is normal?

What is your case? If its a garbage hotbox like the h510 then no sht its burning hot

 

These cpus are toasty so i wouldnt expect any decent oc out of even a d15, ideally youd be running a custom loop with more cooling capacity, though for minor overclocks like 5.1-5.2 then a good aio like liquid freezer 360/420 will suffice

 

 

if you are looking for more performance theres 2 routes for cheap custom looping

 

For a sub 100$ custom loop with actually decent performance, expect aesthetics to be thrown out the window and your setup to be a complete mess along with a bulky car rad hooked up to your pc, though with a massive car rad youll get the best price/performance and ludicrous amounts of cooling capacity if you ever wanna shove >1.5v vcore for 5.5+ or something, tons of effort needed for assembly and ensuring it actually runs but it will steamroll most normie custom loops performance wise and even impressive factor wise depending on rad size, bigger = better, but within reasonable limits so dont go running a semi truck rad thatll be bigger than your entire setup and then some, not to mention how the hell are you gonna get good flow with one of those? Pump wise, >5m h max and thats all that matters, flowrate isnt of much importance cause no pressure = no flowrate and most pumps up in this h max already have decent flow spec anyways

 

If you are fine with spending abit more and would rather not have a junkyard then you can actually get a decent loop with chinese parts while maintaining a decent amount of performance, you just need a case that can house 40mm+ thicc chinese copper rads, heres an example of a beefy rad, sub 200$ is doable even with a beefy rad as long as you dont go overpaying for pump+res, blocks, etc. Linus has made some vids on chinese watercooling parts in the past so check those out

 

Intel 14nm spec is 1.52v so you are fine running up to that volt assuming you can keep cpu <70c cause at this point temp is the main limiter, even at 1.4v its still a limiter

My case is the Coolermaster MB520.

 

I am not interested on liquid cooling as I just bought the Noctua for £100 and I'm just not wanting liquid cooling tbh, I prefer air cooling.

I even run the CPU at 3.5Ghz, all core and it will run 60-70°c but slowly rises to 90°c its like the cpu cooler isn't cooling it right I don't get it though as its a Noctua NH-D15

Have you checked the thermal paste application and mounting pressure?

No I have not, so might I have mounted it wrong?

They are not toasty stock with a D15.

At the most I get 67c running an all core bench and it is much is lower while gaming.

Here is what it looks like.  It runs a 4.8ghz stock on all core with 0 AVX offset and with apps that use less cores up to 5.3ghz.

You are better off stock.

I have not seen anything over 70c with a D15 and it is doing fine feeding a 3090 ti.

 

At stock it will do 4.8 on all core apps like in the spoiler.

Below 70c that it can easily do with a D15 it can hit 5.3 on one core and its normal boost is 5.1.

 

I stopped doing all core overclocks with 9th gen i9s since with 10th and 11th you have to do over 5.1 all core to beat a cool stock configuration that is using all the boosts in games. An all core overclock is good for is a better score in Cinebench and that is about it.

So how would I put it back to stock?

Go into the bios and set to default. Then add XMP again.

Ok will do.

Two things you need to double check, 

1. Your airflow 

2. look into liquid cooling, it is very hard to effectively air cool an alder lake I9.

 

One you figure those out and if you decide to do liquid make sure you check lots of thermal reviews as some liquid tech does not work well on big alder lake chips. I have a 9900KS and run mine on liquid loop and I have never seen it go above 75 degrees.

Go lower from what it's currently running, not all CPUs are the same. It would probably do 1.2V at 4.8GHz but not all CPUs are equal

 

Also turn up the loadline calibration to the middle setting (whatever actually is at the middle, since there are different ways to call them) if you use manual mode. Keep it to.auto if you use other modes like adaptive
