5800x temps?


Recommended Posts

Premium Gold

I installed my Ryzen 5800x a few weeks back in an MSI B450 Tomahawk (non-max) board. It uses Arctic MX4 paste and a Be Quiet! Dark Rock 4 (non Pro). All fans are Be Quiet! 140mm 1500rpm PWM fans, except two Noctua Redux roof fans.

 

I know it's a hot chip, so just wanted to sanity check what i'm seeing.

 

In intensive games, such as Mafia definitive edition, i'm hitting 65c-70c temps. With Aida CPU stress test, it tops out at about 83c. The latter instance obviously kicks all fans up to max and ambient is 20c. Idle temps are ~30c.

 

Does it sound correct? It's certainly hotter than my 3800x, but perhaps this is expected.

Well I find my 5950x does temp spike to approx 70c depending on the application. I have not seen up to 80c, however it is under WC.

 

I believe this is a characteristic of the 5000 series personally as I have seen it mentioned elsewhere. I have even repasted the CPU and put the WC block back to have the same result, so I can only put it down to the CPU.

 

I would say your fine, maybe consider a beefier CPU cooler to handle the spikes ?

I contemplated a beefier cooler, but in reality, I don't really want anything bigger as the Meshify C isn't big. If anything, it would be a slim AIO.

 

But, if it's touching 83c only under synthetic load, I think that's fine. It's within spec and still boosting to 4.9ghz with PBO.

 

I just wanted to make sure I wasn't completely wrong, but sounds similar to you.

I missed that, you did say Aida. Yeah under synthetic load my CPU will near 80c on spikes so I reckon you are all good. Your sanity has been officially checked.

My 5800x behaves pretty hot as well, with PBO set to +200 MHz, it will auto-OC to 5.050 GHz on certain cores during Folding@Home or video encoding and his 85C under water-cooling as well.

 

The "problem", if you want to call it a problem, is that stock 5000 series parts are just pushed at a higher than expected voltage to his those boost targets if you have the cooling and power available.  It makes for some really easy high clocks at the cost of power, heat and a little bit of lifetime.

 

You could play with the voltage and clock settings in BIOS or Ryzen Master to get some better voltage levels, or wait for @1usmus to release Clock Tuner 2.0 RC3 on February 3rd to find some better voltage levels and therefore better temps.

Mine is on PBO but with the voltage curve offset applied which helps. Looking forward to playing with CTR in Feb to see what I can do with that.

They're fine up to 95c. I have a 212 Evo on mine and the highest I've seen is 85c in prime95 with 19c ambient. In gaming, the highest I've seen is 73c (Flight Sim 2020)

What offset do you have applied?

 

I've been messing with negative all core offset today and have the following:

 

Stock PBO:

Temps: 84-85c

Clock: 4525mhz

 

PBO -15:

Temps: 84-85c

Clock: 4625mhz

 

PBO -20:

Temps: 82c

Clock: 4700mhz

Small increase in 3dmark score from CPU and noticeable improvement on CPU-Z bench with offset applied to all core.

 

PBO on, stock:

PBO on, -20 offset

To finalise...

 

Stock PBO:

Temps: 84-85c

Clock: 4525mhz

 

PBO -15:

Temps: 84-85c

Clock: 4625mhz

 

PBO -20:

Temps: 82c

Clock: 4700mhz

 

PBO -25:

Temps: 81c

Clock: 4725mhz

!WHEA errors!

 

PBO -30:

!Boot failure!

 

So, I think i'll leave it at -20 for now... just use the computer as normal and monitor WHEA error log. It seems stable with AIDA stress test.

You get that hot under water? Hmm makes me a little concerned but I am assuming the 5600X should be a bit cooler than the 5800X.

 

What's your WC setup look like?

I will have to experiment and see what I can get, however I am waiting until the new AGESA coming out in Feb.

1x 420mm Rad 

1x 240mm Rad 

200 mm Heatkiller Res 

1x D5 Pump 

1x D5 Next Pump 

Mayhems X1 Clear Pre-mixed coolant

 

All the RAD's have high performance 3000RPM Noctua Fans on all of them. Everything else remains cool under the monoblock (chipset & VRM's) the CPU honestly just temp spikes depending on load variables.

 

CPU block is actually a part of an overall motherboard monoblock (Asrock Aqua)

Oh a monoblock. Higher temps makes sense then. Cool. Put my mind at ease, thanks. :)

Yeah is absorbing a little more heat so higher than usual temps do not worry me too much, plus it is not like it gets anywhere near its max rating.

I just jumped on the 5800x train this week. I have 2x EK CS 360's in my custom loop and an EK Supremacy CPU Block. Stock and Auto CPU everything pushes me to 90C after a couple of P95 tests complete. My RAM is 3800/1900 at C16 and stable. Basically, just the Fast Zen2 Option for B-Die and it's 4 DIMMS in Ryzen Mem Checker for now.

 

Anyway, I'm trying to decide on whether I should replace the CPU Block. I use MX-4, but I think my tube is about 6 years old lol. I spread it and it's tight. I'm folding on 2 1070's only and my CPU is sitting at 72C, GPU's 52C both loaded. I even put a RAD between the GPU's and CPU to try and cool it a little before hitting the CPU Block.

 

Edit: I might even throw some ultra kaze fans on the rads to see what that does lol! It will become a jet engine, but that's a lot of static pressure vs TT Ring+ 12's!

Nice setup !

 

I personally use Thermal Grizzly Kryonaut as my TIM of choice. If your MX4 is old and hard to spread etc, it may be time to swap that out.

 

Good call on the second RAD. I put one in my setup ready for a GPU so I can cool the warmer water from the CPU block a little before hitting the GPU block.

The change was maybe a 4C improvement to the CPU, but the GPU's are 5 C hotter, which is perfectly fine. I think I should have just reversed the order honestly. I think it's probably better overall to have only 1 cooling zone and to put your hottest block first, at least in my case. The GPU's are plenty cool still.

 

 It did spread normally. Not hard at all. I think it's probably still effective, but I may try some new stuff and re-seat it.

 

I just can't get over not comfortably being able to run CPU stress testing the way we used to. Maybe 90C is just the new 70C lol!

 

Edit: I did play with +200 MHz PBO. That was way hotter in stress tests.

Obviously the most ideal is separate loops for both the CPU and GPU, however that is easier said than done depending on the case you have. As for running at 90c under heavy stress/synthetic benches, that is fairly normal for the 5000 series. They can run hot when they want to, not to mention the temp spikes you get, which at first make you think you have messed up somewhere, but no, that is just the 5000 series.

 

Have you tried playing with the offset voltage curve in PBO ? This will help with maintaining a good PBO boost while keeping those voltages down.

Not gone that far into it yet, just PBO +200 MHz at one time which was even hotter, of course.

I haven't given the latest CTR 2.0 a try yet to get some lower voltages, currently with PBO at +200 MHz I can hit 5040 MHz on the cores on my 5800x, but also getting might close to that 90 C mark still.  It does report just hitting 1.5 V max in HWInfo64, so hoping CTR makes a difference.

Yikes...I guess I have been out of this game for a while. Hearing that 90C is "normal" for watercooled is hard to wrap my brain around.

 

I ended up grabbing a 5600X since gaming is the most intensive thing I'll do. Hoping it's lower TDP translates to some better temps as I watercool mainly for silent computing reasons. Would hate to have to start cranking the fans super high.

With the 5800X its a weird combination of factors

  • Lowest bin of CCX's with all 8 cores working and able to hit target speeds
  • Higher TDP
  • All those 8 cores concentrated to one part of the die that is off center so coolers have a harder time targeting the heat directly
  • Really high boost Voltages from AMD and Motherboards to get stable high boost clocks
  • PBO Offset adding even more voltage to get the extra 200 MHz above boost (sometimes even on all-core on shorter burst loads)

 

On the flip side though, the chip and BIOS does an amazing job at just flirting with that 90 C limit regardless of cooling with how fast it can control the speed and voltage.  If I turn my radiator fans way down of even off, the chip will throttle the speeds and voltage down to keep it under 90 C without any noticeable performance loss in everyday stuff.

 

I'd say the 5800x is really under rated since it was seen as the worst in the 5000 range and wasn't covered much by reviewers other then being "bad value", but still better then the 3000 equivalent.

That's really interesting. Thank you for the insights.

I got it figured out. My heat plate fins were oriented in the same position as my jet plate. I had placed the mounting plate wrong, fixed it, and forgot to check that. 20 mins p95.

 

The flow is really good now. I can now get into that oc.
