3900x High temps

[Ashiella]

Common post, I know, stop buli to me >;(
I tried 3 different coolers, 2 different pastes. (Stock, Scythe Ninja 5, H100i V2, Included paste with the Scythe Ninja 5, and Ceramique 2, which from my previous tests is better than MX-4)

As set in ryzen master: CCD0 4.2ghz CCD1 4.0ghz 1.1v core (vcore set to 1.1v in the bios)
Temperatures averages observed using HWinfo, test used was Aida 64 cpu+fpu, Cinebench R20, and 2 simultaneous libx265 encodes, 1080p, main 10, slow, animation, CRF18

Stock: 94c - 86c - 95c
Scythe Ninja 5: 83c - 73c - 84c (Spikes up to 90c+ still happens a fair amount)

H100i V2 (slow pump rpm): 99c - 91c - 99c

 

Scythe ninja 5 stock paste was approximately 0.5c better than Ceramique 2.

 

I see others get lower temps at higher volts so I'm pretty confused.

Is 1.1V what it’s running at during the tests?

Yes, it never differs. It's always at 1.1v
Forgot to mention, the Scythe Ninja 5 literally never gets warm to the touch and whenever the test ends or is turned off, the temps drop from the average to 40c (idle) in just a second or two.

Thought i’d Make sure. What about just PBO? Iirc flat out overclocking on ryzen 3000. Had some weird issues but I could be mistaken

I also see temps in 90*C territory when I run mine with NH-U12A (but stock).

1.1V should definitely result in a lot lower temps though. Whats the power usage reported in HWinfo? I get around 140W when runing Aida64 stress test and my CCD1 tends to spike to 95*C for a few ms from time to time.

Using manual only, stock settings had higher temps, voltages, and lower clocks.

TDC: 90a

EDC: 114a
Power: 141.5w
average temperature: 87.4c

(Doing other stuff at the same time probably has an effect for this run)

well, lower voltage but more current and the same power.... seems like either we both have a bad mount or there is some bad solder between IHS and the die.

From buildzoid video i've seen yesterday he cooled the 3950X until it reached 90*C but it was at 240W on AIO (did't mentioned which one).

I've remounted this cooler 4 times, testing mounting pressure to see which was best, and there wasnt really a difference.

What case and fan setup are you using?

When I'm running Cinebench R20 and Prime95 I never see it going over 73C with fans under 900 RPM and pump at 100% RPM. The highest I've seen my temperatures was around 82C when I'm playing a MMO with 18 instances running when it loads up a new zone data, and if I had the computer on for several hours. My temperatures look about the same as what I was getting with a 2700x. I never tried a X570 motherboard, but I wondered if it because I'm on a B450 or if I just got lucky with a really cool chip.

Looks like bad contact with the cooler.
