cooling for a 5ghz 11700kf

[phanbuey]

Just wonder why Techpowerup can get it to 81 c at 4.9ghz with 1.403 Nhu121s or or a 240mm aio

At 4.9ghz occt temps are okay

Intel Core i7-11700KF Review - Almost as Fast as the 11900K

The Intel Core i7-11700KF has the same 8-core/16-thread configuration as the much more expensive Core i9-11900K, which it can almost match out of the box, and beat with a little bit of tweaking. Thanks to its very reasonable price point of only $390, the 11700KF could also be a tempting...

They don't use Linpack. Use blender.

They would hit 100C instantly at 1.4V on prime/ibt.

I would honestly just send that AIO back and get your money back, just use the Dark Rock pro and Dynamic OC it.

Just for reference IBT @ MAX will 95C my chip @ 1.28V under water with push pull fans 280MM @ 1600RPM -- and I have a 6 + 4 core that runs 50% cooler on top of that. I don't break 65C during daily usage, and barely touch 85C on extended cinebench runs. The only way IMO you could keep that thing from hitting 100C at 1.4 V is to run a chiller or ... just don't run it at full tilt past 250W...

Your velcome to recommend me som better fans than Arctic P12 PWM PST CO

Might not have mentioned it but i only have one cpu fan header

Update
Finally did it with my aio (tdp rated at 200 watt and vcore on aut)

I now need advice if i should change thermalpase if yes to what ?

I use artic mx5, should i buy better fans for my aio, at 1700 + rpm, the artic p12 pwm pst co fan are actually not that annoying, to my surprise the pump noise is much betyter than im used to


I don't think i can go mucvh lower in vcore manually, im thinking 1.330 or 1.325 (peak, it should be no less than 1.310), whne i opened a door the tem went down in the las few run of ibt to mid 80's

Your AIO is exhausting hot air through it, flip the fans around to suck air into the case.

then i would only have 1 exhaust fan

 

[phanbuey]

That's fine.

 

[gasolin]

it's close to my aio and it would take some of the cooler air form the one fan on my aio together with what avere hot air it's able to exhaust,blow,sukc out of the cabinet

I could move my aio closer til the front by an inch, would that make a difference ?

Yes an ich is all you need really, Other option is you mount the aio in the front and put exhaust on top...

 

[gasolin]

Didn't do anything noticeable reversing the fans

I watched a video when they used a 360mm aio in the front of a corsair 4000D Airflow where the dust filter couldn't sit properly

At 4.8ghz i does have 2-3 cores peaking at 100c in ibt maximum

If i don't want to go clc my only choice is a 280mm and mabye buy better thermal paste, fans i don't know (i do how ever have 4 x 140mm arctic p14 pwm pst fans but again only one fan header)

Yes an ich is all you need really, Other option is you mount the aio in the front and put exhaust on top...

More likely to have pump noise in the front ?

UPDATE:
Have mounted my dark rock pro 4

Put the coolermaster back in box and atm settled on 4.8ghz 1.3100 volt, it passes ibt very high and should do maximum as well, only a slight downgrade in single core performance but an increase in multi thread , since stock it only does lower than 4.8ghz on all threads

Mostit should do on all threads is 4.6ghz

For some reason temps are lower and more stable with the dark rock pro 4 than the coolermaster aio at low cpu usage (under 10%)

I still want more than 4.8ghz but even at 4.8ghz it's peaking at 100c on a few cores in ibt very high but is stable, occt is more normal, as you would expect around 80c mabye peaking around 85c

Update i bought a EK Water Blocks EK-AIO Basic 360 from caseking de

Just thought I'd add this link here to explain why RL has had reputation for power hungry consumption in the industry. MSI boards & is mentioned a few times, Asus boards, have an option in CPU advanced menu in bios to enable "CPU Lite Load". Its even available on B560 boards. The link is in German, but google translate can help. Quite a reduction in CPU power consumption can be achieved if this feature is exploited. All up a nice read that thread!
It's also relevant for Intel boards back to Z390.

Cpu lite load did nothing for me, since vcore on aut doesn't go as low as i have it set manually

 

[Arctucas]

Wow does 11th gen need that much more voltage then 10th? On my 10700k with z490 unify and corsair 360mm rgb pro xt pump with 6 noctua ip67 2000rpm in push/pull I do 4.9@1.175 5GHz@1.2v and 5.1@1.230 5.2@1.3.

I was thinking the same thing.

 

[gasolin]

I was thinking the same thing.

The 10700k(f) need less voltage than the 10600k(f) the same goes with the 11600k (f) vs 11700k(f) even the 11900k need less than the 11600k

Mabye because if the 11900k needed as much as the 11600k nothing would be able to cool it, do to more cores,threads the 11900k stil by a long miles get's hotter https://siliconlottery.com/pages/statistics

I need 13.100 volt for 4.8ghz and 1.350 volt for 4.9ghz

 

[Arctucas]

So, when you say you need 1.31V @ 4800MHz, and 1.35V @ 4900MHz, is that idle in Windows or load or what?

In the Bios

Which matches okay with the silicone lottery experince, between the i5 and i9 11gen

If you are doing old fashioned OCs(full time) at 4.8GHz you use 1.35

Yes, Atm the moment with my current setup i think 4.8ghz is the sweetspot, for 4.9ghz i need alot more airflow, 5.0 ghz is something i don't think would give me under 100c in the most demading stress test when it's not summer, i already have some peaks at 100c at 4.9ghz in ibt, prime 95 fft or aida64 extreme

Im considering a case with more fan option i was looking at the LIAN LI O11 Dynamic EVO https://lian-li.com/product/pc-o11-dynamic/ with it 3x360mm aio options but pricy.

I only have in my corsair 4000d airflow the 360mm aio in the front, 1x120 in the rear and 2x 140mm in the top, all 3 fan are exhaust and i think i need more intake fans

My gpu host spot is 100-103 c (rx 6600 xt red devil) i just dont want it to be noisy, something like 240/360mm buttom, 240/360mm top and my 360 aio in the side or front all at low rpm, under 700rpm until temps goes up to 75-80 and i think max speed at 90c

Set VCore?

1. For AIO you can get up to a 10-15 C difference between intake and exhaust orientations (this is especially true for silent setups) -- when you're shooting for quiet, you need the air as cold as possible. Exhausting hot air through the radiator is going to make it less effective -- Intake is the way for a silent AIO setup.

One thing to that: While an intake AIO decreases your CPU temperature by cooling the rad with fresh air, your GPU has to make do with the warm air exhausted by the rad, so its cooler has to work harder (and louder), and you may lose a couple of temperature-related boost bins. Not worth it. The best solution (in my opinion) is to use the AIO as exhaust, and find the ideal tune where the system is stable and the CPU is under roughly ~85 °C in all scenarios. That way, the GPU works with fresh air, giving you the best performance and quietest operation possible, while your CPU still remains in its optimal temperature range. Whatever clocks you have this way, you won't feel the difference in real life, anyway.

No it doesn't, i deside how loud the fans are, generally the hostspot is hot on a rx 6600 xt https://www.techpowerup.com/review/xfx-radeon-rx-6600-xt-speedster-merc-308/32.html I just felt like i might need a better case for a 360mm aio, since i only have the aio as an intake

It's 4.1ghz.

Try 4ghz.


Im quite sure cpu will need less volts then and 5ghz doable at 1.30-1.35v.

I would agree with this -- generally CPU temps and clocks matter much less than the GPU. In his case his AIO is at the top and he has 3x intake fans blowing fresh air into the GPU or he has a push pull up front so the air out of the AIO won't get hot enough to matter.

Cpu lite load did nothing for me, since vcore on aut doesn't go as low as i have it set manually

So you went through all 23 levels of cpu lite load that MSI have tested extensively to cover a broad range of silicon quality aka "silicon lottery" & none of them are better than what you claim to manually dial in for Vcore?
Is your system stable when hammered with LinpackXtreme stress testing? I'll bet it isn't.
For the clock speeds your running, you've mentioned 4.8-4.9GHz, set it to auto vcore & try each of the levels in cpu lite load.
I did it on my rig with 11700k with auto vcore & a set value for cpu lite load option, now my cpu runs about 10 - 15C cooler in gaming with a "custom" auto vcore designed for my particular silicon quality. With this it saves my VRM working there asses off trying to stabilise a manual vcore, at least with the toughest stress test out there aka LinpackXtreme.

 

[gasolin]

9 should be stock, i got it to 1 without crashin but only at 4.8ghz

Vcore was so little in difference and temps, that manually 1.310 is better since i know it's stable

you only get 10-15 lower temps if your using high vcore and the cpu can handle so much lower that the temps would go down byt 10-15c

Not a case here
