I9 9900k help with cooling

[VandaL]

Can I just ask, you do have fans on your radiator right, and the air flows through the radiator easily?

Just checking

I think photos of your loop will help

I'm assuming if the man has made a custom loop he's going to put fans on his radiator lol

Photos will help for sure, no matter what cooler you put on this beast it runs HOT. As @pXius said direct die is the most effective. Gotta take some concrete pills and risk breaking his R10k if he cocks up

Lol. In that case, before I cock it up it will have to run stock.

Radiator mount on the back on two brackets behind the back fan and the two fans on the radiator pushing from the back.

On the website they show airflow direction that can be used. Maybe try that

Also there is allowance for a 240mm rad in the front of the case, did you not have space to mount the RAD inside?

Okay, based on my limited experience on a 9700k and assuming Intel has taken over from AMD with the melted snow on the roof phenomenon...
On my 240mm RAD system, the processor would top out at just over 60c, loop temp just over 40c (Ambient of 22c)
Added a 360mm RAD yesterday and the processor doesn't go over 45c, loop temp +/-5c over ambient. (Ambient of 22c)

So yes, adding another radiator would help the 9900K's cause.
Also rather have the two fans at the topmost point in the case suck air out.

 

[baltazhar]

Isn't a 240mm rad a bit small for 9900k even if is a custom loop?

Like 360mm would mean more surface area to dissipate more heat and more fans to do it...having push pull 3×120 on the rad and a custom loop system should keep it ice cold

Yip, wasn't enough for my 9700k.
Min for a 9900k IMHO should be 360.

So you inside rad fan looks like it's pulling hot air directly from the external rad fans.
So you just pushing hot air back onto your loop.
I'm no pro but maybe have your external fans exhausting away from the case.

Staring from Rad,
Fan pushing through rad.
Back fan pushing in case.
Top fan exhaust.
Front two fans pulling in case.

And what fans are you using on the rads?
Actually what fans are you using all over?

3x 120mm coolmaster
1x 200mm coolmaster
2x 120mm larkooler came with watercooler kit

Delidding a CPU that is soldered has a high rate of one ripping the CPU die right off.

 

[RandomSheepZA]

So that might be one of your issues.
Better fan will definitely improve the airflow through a rad.

I have never heard of larkooler.
Maybe look to swap out the 3x 120mm CM fans for decent static pressure fans
Not sure what your budget would be but I would recommend Corsair ML120 Pro's
Could in face just replace all the fans with those.
I would also make sure the external fans are pulling through the rad and exhausting away from the case.
As for the 200mm, just leave that.

 

[RandomSheepZA]

Sorry I thought you had 2 rads, an external 240 and internal 120.
I would look at definitely adding a second rad into the mix, you most definitely don't have enough cooling surface area.

 

[No-Rules]

No worries, I will look t replacing all fans with what you mentioned and look at rebuild the loop and either add another rad or replace with a bigger rad.

I'm in agreement with @Random_Sheep you need better airflow across the rad...I would push the air through the radiator for better static air flow.

Also make sure they face away from you case so push air away...

CoolerMaster H500M should solve all your problems.....

Aside from airflow...

That water block is proper old school. Larkool did kits in like... 2013? Nothing wrong with it, but I don't think they had 9900k level TDPs in mind when that was designed.

If the spike in temps are very rapid it might be the blocks inability to transfer heat away from the chip fast enough. There's no way for me to state it as fact, but I'm pretty sure you'll be better off with a modern AIO like the H115. Especially if you consider that you already have the rad outside the case which really is best case scenario.

@adamr Has a H115 on his 9900k with 5Ghz all core and pretty good temps. Maybe he can weigh in.

Edit:
So quick edit, after some pondering.

If you are getting 90-100C @ 1.34V /5.1Ghz with an AVX instruction workload 100% utilization, then it's actually not that bad considering the cooling solution.
Even though it's a "custom loop" it's comparable to an AIO in it's current configuration with a slightly bigger thermal mass in the form of a reservoir.

5.1Ghz or more specifically 1.34v on the 9900k is really larger loop territory. So as I see it you can do the following;

1. If you have confidence in the cpu block you can add another rad.

2. You can get a something like a 115 which has a 280mm rad giving you 36% more radiator surface. You lose the thermal mass/res so water will heat up faster but also dissipate heat quicker. You also get a better CPU block. It should be fine for gaming, but full load 1.34v will still overwhelm a H115. (unless you're a Reddit user in which case your H100i can handle 1.8v on a 9900k no problem).

3. See how low you can go on voltage @ 5Ghz. Most mid range chips do 5Ghz @ 1.29V - 1.31V easily.

Option 3 doesn't cost anything, will drop temps significantly and the performance cost outside and even in benchmarks is negligible.

Thank you all for the input. I will relook at my setup and start tweaking it accordingly.
For now it back to stock to first sort out all my bugs.

Yeah I'm running 1.28v with 5ghz across all cores. Max CPU temps with load is 70deg c. Cache is 4.6ghz. all voltage and current limitations have been disabled in bios. AVX offset is 2. I'm running a very quiet profile on my h115i platinum cooler.

A few reasons for this temp
1. I used washers behind my Maximus board to ensure the cooler plate tightens and fits properly against the CPU. Some motherboards are thin by design and the h115i cooler needed this modification
2. I did use thermal grizzly paste which should not make a big difference but I'm sure it has helped with temps
3. The big one for me ... My radiator is mounted infront of the case and not ontop. What did happen previously is that heat from the GPU backplate would rise and soak the radiator ... Thus my CPU temps would be 75- 77 deg c or there about ... A front mounted radiator has increased my gou temps slightly around 71-75deg c whilst the my CPU temps dropped a fair bit

Is this 70c under a blender load or just general usage? I'd be curious to know what temps it hits with a prime95 small fft load.

 

[huzidada]

Aorus, and anything made by Gigabyte is rubbish. Just get an Asus board.

WTF??? Biggest load of rubbish Ive heard on this chipset!

 

[huzidada]

Hi all,
I'm fortunate to be running a I9 9900k on a aorus z390 ultra board.
Currently running it at 5.1 stable, but sitting with heat problems. Full load 90 - 100 max idle 35-40.
It's on a custom loop 240 radiator, not sure if I need a bigger radiator.

Can someone give me some advice please trying to get the temps down.

Sent from my CLT-L09 using Tapatalk

Is the 5.1 neccesary? I have mine on 5Ghz on all cores and max temps under load is 72 to 76 degrees on a H150i AIO.
What is controlling voltage? Do you have load line calibration on auto?

Edit- what are you using to stress test? AVX instructions?

That's under cinebench load and some decompression stuff that utilised all cores ... Not prime95 ... Gaming temps are max 60 deg c and less ... Most games 50dge c.

Please download and run OCCT. Leave that for twenty minutes and report trmps. Actually send a screenshot if you can
