Hi,

I just recently upgraded to a Ryzen 7 5800X3D in one of my AM4 rigs. I'm using the ASUS Strix B-550F motherboard with the latest BIOS from ASUS. I've got a Corsair H150i RGB PRO XT with 6 120mm fans setup in a push/pull configuration. I'm surprised at the high temps during gaming. Both M.2 slots are occupied.
The CPU boosts to around 4300Mhz and stays locked at 91C during game play. The only BIOS setting I've enabled is the DOCP for the RAM to run at 3600Mhz. I've tried remounting the CPU cooler but still no luck. My hunch is that there might be a BIOS setting that I'm missing as there's no way this thing should be running this hot.

Any ideas?

Update
I submitted an RMA with Corsair and was sent a Refurbished Corsair iCue H150i Elite RGB Liquid CPU Cooler. After installing the idle temperatures were around 49C, a huge improvement over previous results.

It’s designed to run around 90*c, that’s just how it is. Do a quick google search you’ll find the answer quick.
 
That is pretty hot. I'm running a similar configuration at the moment, a 5800X3D with a 360mm AIO with 6 fans in push-pull and my temps get nowhere near there, even when I'm running Prime95.

Still, there are some key variables. What are your ambient air temps? If you're in an area experiencing a summer heat-wave and you're trying to save on your electric bill by going easy on the AC and letting it roast in your house then those high ambient temperatures will absolutely make a difference.
You said "during game play", but what game? Is the game actually fully utilizing all 8 cores? Are you hitting 100% CPU utilization during gameplay?
How old is your AIO?
How are you applying paste when you mount your waterblock?

I'd be curious if there is an issue with your AIO. Have you verified that your pump is operating at the correct RPM? I've seen people plug their pump into the wrong motherboard header, where the motherboard is trying to control it like a smart fan and it causes issues with the pump RPM. If it's an older AIO, there could be issues such as not enough coolant (some coolant will evaporate over time no matter what, and coolant can evaporate very quick with a very tiny pinhole leak), or it could be grime buildup, corrosion, a failed pump, etc. Mine is 5 years old and still going strong but I've had others that didn't even make it this long.

You said that you already tried remounting it, but if you're not doing a good job with the paste, doing it the wrong way over and over again won't fix the problem. It's cringe-worthy how many people out there think that old techniques like the "grain of rice" method are still the way to go.

There aren't many BIOS options that will increase temps on this chip. AMD didn't even allow any overclocking on the 5800X3D, although some motherboard makers put things like PBO back in anyway. Modern overclocking is mostly done via PBO and negative curve optimizer offsets, which should actually decrease the voltage and temps.

  • Ambient Air Temp is 23.8C
  • The 91C is hit when compiling shaders or downloading a game to one of the NVME M.2 drivers
  • I'm around 79C in games such as War Thunder, which aren't very CPU intensive.
  • Idle on my desktop I'm at 62C and my 120MM case fans are around 1800RPM so they aren't quiet by any means
  • AIO was purchased NIB from NewEgg in August 2020
  • I used newly purchased Thermal Grizzly - Kryonaut
  • Spread using the included spread nozzle prior to tightening the AIO
  • iCue reports 2814 RPM for the pump at idle
I noticed the poster above you mentioned that 91C is normal, but in my experience (Join Date 2004) this isn't normal. I appreciate you taking the time to reply and help me think through what the issue may be.

Join date has nothing to do with it. Those chips were DESIGNED to run that hot. It would have taken less time to look it up, than it did to type your long message mentioning a join date.

And since I’m feeling fancy I’ll link you to AMD’s website with the official specs.

Than you can…. Do some actual research.

https://www.amd.com/en/products/processors/desktops/ryzen/5000-series/amd-ryzen-7-5800x3d.html

Designed working temperature is 90 degrees Celsius.

Sure that’s confusing. And yes it was a question everyone asked when they got the chip and noticed its temperature. But again, it’s been said and covered. These chips are DESIGNED to run hot. It’s not a problem. It’s designed to boost to whatever it can until it hits 90c.

Also the newer x3d chips do the same. It’s because there is an extra layer of substrate that has to do with the 3d cache. Good for gaming bad for heat dissipation.

A little research goes a long way.
 
FWIW, I use the offset bracket on an Arctic Liquid Freezer II 420 on both a 5800X3D and now my 7800X3D. In games, temperatures for both CPUs are in the low 60s. When shader compilation is happening, I see around 74C. The 5800X3D is now using an old Noctua NH-D14, and doesn't see much more than mid 70s - it still boosts to 4450 all core. That's with a -20 voltage offset, which did help knock off 5 to 10C.

The offset mount puts the cold plate more over the CPU die, as the IO die doesn't need as much cooling.

With that said, 91C is hot for an X3D chip. It sounds like you have a bad mount, or possibly the pump isn't working well.
 
its not as cool as we would want but it is operating within spec. maybe try turning the pump up to max. could also try turning down the voltage a bit.

That's actually not the case here. 91C is above the max temperature rating that AMD gives the 5800X3D: https://www.amd.com/en/products/processors/desktops/ryzen/5000-series/amd-ryzen-7-5800x3d.html (expand all and search for "max" - it's the second one. 90C)

that looks within spec to me. the chip will start to throttle over 90.
 
arestavo said:
Throttle, of course it will. The 5800X3D has a tjmax of 90, not 91.

The cooler has issues, or the cooler mounting is bad. My ancient NH-D14 works much better.

which means it was down clocking...
possibly, but the chip is within spec.

It is not in spec at 91C.

If it was at 90C, yes - because that's the tjmax for a 5800X3D. But it isn't at 91C, so it is not in spec.

The OP needs to check their cooler mounting. Applying a core offset voltage would also help some, assuming that the board/BIOS supports it.

Also, water is pretty wet and the sky is fairly blue most of the time.

temp readings arent perfect, and depending on what software hes using can be off. i dont see a pic or mention of what hes using. plus the max temp is only being hit during compiling, when the cpu is running at max. my 5600x hits mid 80s during compiling on my custom loop.
 
Was the cmos cleared when the cpu was switched? Check soc voltage for the memory controller I think it might be higher than it should be.
 
Despite what someone said, the 5xxx series is not designed to be run at 90C. That was the 7xxx series. 90C is the throttle point.

Something definitely sounds wrong with your cooling setup. I have a shitty, low quality 5800x (that loves to eat voltage to boost) and with a 240 AIO in push/pull config and the only time it will hit 90C and start throttling is when running an all core AVX workload and usually stays at 88C-89C with that workload. A 5800x3d with a better cooling setup than mine should not be hitting those temps.

As mentioned the SOC voltage needs to be checked as some XMP/DOCP profiles will automatically set a very high SOC voltage despite not needing it which can increase temps quite a bit. I didn't have that issue with my 5800x and Gigabyte x570 board but did have that issue with my 2600x and Asus b450 board. Even if the SOC voltage is set quite high I don't think it's the main problem and the AIO needs to be checked out.
 
That CPU should be in the 40's when idle under a 360mm AIO, not the 60's.

I'd reset the bios to factory default and then just enable DOCP. If nothing changes, then I'd try a cheap air cooler to see if the AIO is faulty if you've remounted it already with no changes.

Does it do the same thing with DOCP off?

So I just reset the BIOS to factory defaults and I'm still getting the same high temps. I noticed that when I increase the load on the CPU, the CPU voltage jumps up to 1.28 according to Ryzen Maser. The increase in voltage raises the CPU temp. I'm wondering if there's some sort of setting for the ASUS Strix B550-F motherboard that pumps excess voltage into the CPU which causes the higher temps? I downloaded HWiNFO 64 but most of it is totally foreign to me since I'm not into overclocking.

its an asus board, it probably has some type of cpu "enhancement" on by default.

Here is a screenshot from me running Cinebench R23
Does this help explain anything?

voltage is high and you probably need to set the pump to max however your controlling it, and probably adjust your fan curve.
 
Burke888 said:
Thanks Pendragon1, I went into the BIOS and confirmed that is turned off. My ASUS Strix B550-F has that exact same setting on the Ai Tweaker tab that was in your screenshot.

ok. then lower the voltage a bit. running the curve optimizer might do it too, but manually crank up you fans and pump first.
 
I don't know why people think its a voltage issue. Your voltage is fine, your temp is NOT. If your bios is stock default then that's not an issue. I have the same board and its solid with voltages. IT"S YOUR COOLING SOLUTION! recheck your AIO mount. Thats always the first thing you check if temps are bad on a DEFAULT bios setting. I don't say much on hear normally but there is way to much misinformation floating around in this thread........troubleshoot and find the root cause. Your cooling is your first check
 
Now think about it for a sec, he's hitting 91 celsius while only running 1.119 volts and a 98w package power. It's a cooler issue whatever that may entail.
 
Second, the water temp in his AIO is only 26c while his CPU is hovering around 90c at 98w which means there's not much heat transfer happening between his CPU and the water block which also dictates the fact that there might be an issue between the CPU and water block ie. a paste issue or a plastic piece issue or a mounting pressure issue etc. I know it's only a limited run of cinebench r23 but the CPU temp shouldn't be that high with a water temp of only 26° EVEN THOUGH it's an X3D which do tend to run a little (+- 5c) warmer.

I think it's an AIO issue too. I just got an error message when booting my PC that the CPU fan was not detected despite the AIO being plugged into the CPU fan header on the motherboard. The only way to get into Windows now is if I disable the BIOS monitoring of the CPU fan header. Just to confirm there is no plastic between the IHS of the CPU and the AIO block. Even though iCue is reporting an RPM value for the AIO Pump, I don't think it is functioning properly.

I just submitted an RMA to Corsair so hopefully a new AIO will do the trick.
 
Don't plug the pump into the cpu fan header. There should be a pump header. The fan header might not have enough amperage to push the pump properly.
 
In the meantime, grab one of those Thermalright HSF's from Amazon for sub-$40 and see if your temps improve.

I don't think it's an issue with your pump in my opinion. If the temperature is staying low on your water temp that means your pump is circulating the water. If you pump wasn't working then the water temp in the water block with skyrocket if there was good contact with your cpu. Make sure you plug the pump into the AIO pump header and the fans that are on your radiator into your CPU fan header. Go from there. Make sure that the AIO pump header in the bios is set to Max just to take that out of the equation.
 
And make sure that you're making proper contact to your cpu. Did you use the correct standoffs for AM4 vs AM5 for the pump?

Yeah, and what does the contact patch look like if you pull the pump?

I saw that and I understand but did he check pressure and contact patch when he did it? Did he also check to make sure that he's has the right mount on it? As per my previous posts. I read before I post, guys........

the stand offs, maybe, if hes using intel ones instead of amd ones (which are the same afaik)(you might be right, confusing am3/4 zif vs am5 being lga now)
but im assuming he would have checked the patch, what would be silly not to check during a remount.

It might be silly not to check but I don't assume anything. Everybody learns by experience and if somebody hasn't experienced that before then how would they know properly what to look for? I just go by what I see and try to help troubleshoot from there..

well hes been around here since '04, and is building custom systems.....
same.
i also updated my last post, you might be right on the standoffs, if its a contact issue.
