9950x with Arctic Liquid Freezer III 360 - Hitting temps in the 80c during gaming.

I’ve got a 9900 on a x670 motherboard and stress tested it using cpu-z. I have a Corsair 115i platinum water cooled setup and it hit about 70C. Mine is a 120 watt part whilst your is 170 so it’s gonna run hotter considering the cooling surface area is the same
You should try what I did with my 9900X I adjusted the PPT/TDC/EDC I used the suggested numbers then I started moving the PPT TDC EDC up slowly while watching everything with HWInfo and I watched the PPT TDC EDC,I settled on 130Watts as the total whats the my 9900X can get and the stock is 162Watts,I adjust the TDC/EDC so that when I run Handbrake the TDC/EDC are at 80% that way there still a bit of headroom.

I find Handbrake makes the CPU work a lot harder then Cinebench and my temps while running Handbrake and stock bios settings and the only change being was I set my Ram to EXPO1 and with a Noctua NH-D15 G2 newer version of their cooler I was running at 71C when using Handbrake.

After my changes I'm running at 51C to 55C when using Handbrake and almost no change in performance,I was getting 643FPS conversion speeds encoding a .265 file and after my changes I went to 618FPS for .265,with H.264 I was getting with stock settings 1106FPS and went to 1083FPS.

I also used Curve Shaper and for the Medium part I set it to Negative 15 for all 3 parts in the Medium part of the Curve,for High I used Negative 20 for all 3 parts of that curve,with Curve Optimizer I gave all the cores a Negative 10.

I went from 71C to 51C to 55C while running Handbrake with almost no difference in encoding times by maybe 5 to 8 seconds.
 
@Acastus Try looking at this thread,I wasn't having heat problems that were extreme for my 9900X and I was able to get my temps down by 16C by adjusting the total amount of Watts that my CPU could get while running Handbrake which I find makes my CPU run at 71C with stock bios settings and Cinebench 55C with stock settings.

Try asking @Tetras for the stock PPT/TDC/EDC values for the 9950X I can not find them on the net and he was the one that posted them for me and also his suggested numbers at where to start,I then used HWInfo as suggested and raised the numbers slowly and once I got to where my CPU was running at 55C while encoding with Handbrake and noticed my encoding speeds and times were about the same I then focused on the TDC/EDC numbers and raised those numbers until the TDC/EDC were at 80% when running Handbrake to have a bit of headroom,I was concerned about not bottlenecking the TDC/EDC,where as the when the PPT number is set it always read 100% in HWInfo when running Handbrake no matter what it set at because Handbrake loves to max out the CPU,so when I settled on 130Watts for PPT I adjusted TDC/EDC.

 
I've managed to get the temps down except (obviously) when the CPU is at full load. I had to reseat/repaste, for a third time, the cpu and most importantly, the AIO needed to be attached tightly to the CPU. I'm idling at 41c, moderate workload takes it to 70c and Unreal Engine work and gaming takes it sometimes to 95c, but never above. I've thrown everything graphics intensive at it and left it running, no crashes and no shutdowns.

One thing I have noticed that has made a considerable difference is the c36 64gb 5600mhz DDR5 ram.

Here's a pic of the setup.

@Acastus you never got back to us about the pump speed setting in bios? what do you have it set to it should be fixed at a minimum of 75%

the problem you will be having with heavy load is coolant temp. with an AIO where you cant monitor coolant temp and have fan set to ramp with CPU temp is ones the coolant get heated its very hard to get it back under control.
you need to set your fans up to ramp in steps so you keeping onto of the coolant temp.

if you set the fans to 100% and retest you will see your temps drop as the coolant is under control and able to do its job.
what you then have to do is find a happy place where when gaming and so on your fans are up enough to cool the coolant but also not bug you

my fans are fixed at 600rpm but if my CPU go's over 45c they just to 1000rpm(still silent) but at over 55c(gaming load) they jump to 1200rpm. making more noise but covered up by the game sound
this keep my coolant under 34c and im happy at that

obviously your CPU puts out a lot more heat and runs at different temps than mine

@WARburton My god, the fan settings in the bios were set to ultra quiet mode. I've set them all to performance mode based upon CPU temps. if it's above 50c then they go full blast. I'm going to do a few more tests but so far temps are 38c - 41c idle.

Just tested GTA V maxed settings. On this new performance mode, the CPU doesn't hit 80c ever.

Silent Mode in Bios settings for the fans was the enemy here.
 
@Acastus Did you try lowering the PPT/TDC/EDC in the bios under PBO,I lowered my PPT from 162Watts to 135Watts and I lowered the TDC/EDC and I'm running my 9900Z at 55C max temps with a Noctua NH-D15 G2,my 9900X was running at 71C when I run Handbrake which puts more of a load on it then Cinebench which only took my temps to 55C.

The reason I suggest lowering your PPT a bit by 10Watt's or so may help a lot,I was getting 643FPS speeds encoding .265 files now I get 618FPS and for H.264 stock bios settings 1108FPS now 1083FPS,it makes very little difference time wise for me like maybe 3 to 7 seconds for a 40 to 48 minute encode running Handbrake which is nothing of a loss really when you think about.

I was shocked when I was able to drop 16C and barely affect my encoding times,I honestly thought the encoding times would have suffered more then what they did.

I understand for gaming you don't want to loose to much FPS but who know how much it will affected unless you try.

I haven't tried any of that. I'm going to monitor the situation now that I've set the fans up correctly in the bios. If I get problems still with super high temps I'll try the solution you posted. And yeah, I'm not a gamer that needs to extract every last fps they can from their setup. I'm more interested in the setup not breaking due to heat problems. The 9950x is not a cheap bit of kit. Yes there's warranty but it's the downtime and the hassle.
 
if it's above 50c then they go full blast.

so now start retesting and dropping it by 10% at a time and you will find a happy place. i wouldn't think 100% would be needed you could probably drop to 70% and not have a massive temp change.
did you identify what header the pump is set to, this header need's to be set to a constant speed, this will help with idle temps and keeping the coolant cool under low load

The pump and the rad fans are all controlled via one cable. It's the option I went with. Is this wrong. The Arctic LF AIO 360 came with two cables. One cable allows the fans and the pump to be controlled as one and the other cable splits the pump and fan control.

Currently I'm using the single cable plugged into the CPU fan header.

[edit]I'm going to try the 2nd cable. Let's see what happens if I implement your suggestion about the pump.

lets say your fans spin down to 30% and this also spins down your pump for me this is not good its not moving coolant i had a corsair AIO some years ago now and at idle uf you touched the tubes one was hot it turned out the bump was running slow and not moving the coolant. im sure it was on somthing like a 6700k and the 240mm cooler was limiting my OC.. because i had it set up like crap. i thought they was just plug and play

right. i would think on a CPU like mine this would be an ok option, yours is a big boy and and yer i think it should be split.
also running 3 fans and a pump on one header for me is a bit dodge with power draw

@WARburton Turns out you were right. I plugged the cable in that has separate connectors for fans/vrm/pump. I set the AIO pump to full speed, the fans to a custom set of speed settings based on cpu temp and the cable (vrm) to full speed also.

idle temps are now between 39c and 42c. Moderate load hits 60c to 70c. Here is the gamechanger. Maxed out cores in a stress test the cpu hits 78c max and doesn't increase. The cooler is doing its duty well. 78c max is very far from how this all started (95c temps ) on moderate load.

Just want to say thanks for taking your time to help. It's appreciated and has actually made a phenomenal difference.
