AMD Ryzen 7 5800X 3D Cache Eight Core 4.5GHz (Socket AM4) Processor - Retail - Go Go Go xD

New chip and heatsink all installed and running happily. Have been tinkering with fan profiles so not tried to tweak it yet. Chip temp with the aio seems to bounce up very quickly and regularly under any load into the high 60s. Seems to be hitting 80oC under full load and around low 70oC under most games I've tried so far.

Upgraded to the Artic Freezer 420 to go with the the 5800x3d.

Very noticeable in games with a good fps jump from the 3600x I had before. Happy days so far.

Any chance you could load up Prime95 and run the small FFT stress test? Would love to see how the Arctic Freezer copes with that.

Granted its an extreme case but really good to show how good the CPU cooling solution is.

The 5800X3D is a toasty chip and I've always wanted to get an AIO, so keen to see what kind of temps you get.
 
I eventually got round to fitting my 5800X3D the other day. I did notice it ramping up in temp fairly quickly but also drops temp fairly quick too.
For one game of WZ2 it hovered around 68-69Deg during gameplay so happy enough with that. Will keep an eye on it though.
 
Small FFT test temp went straight to 90(.1-.5) within a second. Starting cpu temp was 40oC according to HWInfo.

Stopped the test and CPU was straight back to 45oC, maybe a minute to 42oC. At that point slowly and steadily dropping back to 40. It did take ~3 mins to go from 42 back to 40.

I am using the program Fan Control for the case fans. It doesn't detect the aio as such and doesn't give me any control over the fans. The aio fans span up a tiny bit maybe but I'd say didn't really change rpm. Unless I've missed something Artic don't have any software so not sure what the coolant temp is.

Fan control should really pick up the fan on the aio. Have you run the fan detect mode? You can label the detected fans then. Can you see the fan in the bios?

I use fan control and find it occasionally buggy in the UI but once it's set it's excellent, considering it's free

Wow. Even the Artic Freezer 420 can't tame this beast! Granted its an extreme use case the CPU and cooling will never have to encounter but still a good test.

Don't think I'll bother swapping over from air cooling.

Mine ramps up to 90oC within seconds and stays there with the CPU throttling clock speeds down.

An undervolt results in the same Prime test hitting 84oC (Cinebench around 74oC and gaming less than that).

Judging from your temps, I don't see the massive improvement it would bring considering I'd have to spend £100 and then faff around installing it.

Might have to reconsider if we get another summer like this year.
 
Had a blast On Plague Tale: Innocence last night and in my new Phanteks P600S case CPU temps reached 85c on my Noctua DH15 Chromax with 2x fans. I did get a weird crash yesterday, but even checking the event logs I am not really sure what it was attributed to... could have been the GPU.
Wow that temperature is too high for a game. I’ve got that cooler and Spider-Man which is heavy on the cpu gets about 64c max.

The 5800x3D has a max operating temperatures of 90c so reaching max spikes of 85c is not unusual, especially in a closed case that has a hot RTX3090 in it. I also don't run the CPU fans at 100% to keep noise down.

If you are maxing out at only 65c and have the same cooler I would assume that your ambient temps are low or you are not stressing the CPU anywhere near as much as you think you are. Go and run Cinebench and then record the max operating temp that it reaches.

EDIT - Ok I just followed this tweaking guide and enabled Kombo Strike 3 in my MSI BIOS in addition to the other settings he mentioned https://www.resetera.com/threads/ry...mps-less-power-consumption-better-cpu.660658/

Running Cinebench and max temp is now 83c and I get consistent boost on all-cores of 4350mhz @ 1.2v, 75% of PPT, 77w of CPU power. Seems like a decent improvement to temps but I am tempted to just say screw it and buy the Arctic Freezer II 420mm as my P600S case will fit it.

EDIT EDIT - Just had a quick blast on SkyrimVR and the minimum framerates are very much improved and the game is overall just much smoother than it was when I had only my 5800x in there and I got a lot of stuttering. I'm looking forward to seeing how it does combined with a 4090!

Same, 70c in gaming not Prime.

It’s a gaming chip though, not a Cinebench and Prime95 chip!

Gaming, this means 20c-30c of headroom, plenty
I'm about the same with my Corsair 150i.

29 idle, but using chrome and general use I'm at 50-60, bf2042 was I think 70.

Prime, on default hits 90 after a short time.

I think this is fairly normal right?

Way better than my 3900x for sure.

The only temperature that's too high is one that causes throttling, unless you want your PC so sound like a jet taking off.

I would say that is not the case with my setup. The Noctua D15 with push / pull fans is a monster cooler. Add PBO tuner with a -30 offset. The 5800x3D can be tamed during CPU intensive gaming sessions. I also have a very well ventalated case.

I've played around with fan profiles some more. It seems the first run of prime that I did, had the fans, pump etc barely turning. Not seen it go past 86oC since setting up proper fan curves. And that's with running the tests for long enough to saturate the coolant. It took around 10-15minutes for that to happen.

Prime95 Small FFT test and it now jumps straight to the low 80s and then slowly creeps up and stabilises around 86. Starting cpu temp was 35oC. Stopping the test dropped it straight down to just over 40oC and then slowly dropped back to 35oC over 3-5minutes ish.

Under this max load Vcore was reading 1.280v; CPU Core Voltage (SVI2 TFN) was 1.175v. And HWInfo didn't flag any thermal throttling.

I've not had chance to get on my son's new PC after building but hes been quoting mid 60s and coolant temp of about ,35c on his H100i not sure if ICUE reads case temp or die temp but I've not tried undervolting or anything it's all stock

Idle in bios was about 35c
