R7 5700X3D running really hot

[Vasllo]

So, I've upgraded from my i5 10600KF with which I used to use a Deepcool Gammaxx 400 XT with a Corsair ML120 Elite fan and temps would be absolutely fine, wouldn't ever reach 70°C while gaming, even with ambient temps over 30°C. At most, it would hit 85°C on a hot day on Prime95 small FFTs.

 

Sadly I didn't have the mounting hardware for AMD, so I bought a Deepcool AG400 Digital and thought it would be fine, it was very similar to what I used to use and this R7 pulls less power than the i5. Boy, was I wrong. This thing idles at 50°C with my AC on and at high 50s today, a really hot day. And it thermal throttles on Prime95 even with AC on, in a matter of seconds, it reaches 90°C and stays there, pulling ~102w today or ~110w on AC. And I often see it jumping around the 70 and 80°C range while loading Windows or some burst of heavier load.

 

I even removed it to see if something was wrong, but it seemed like the pressure left just a thin film of thermal paste as expected. And no, I didn't leave the sticker on. I'll try to repaste it once again with newer paste (GD-2) and see if it improves, even though this has lower thermal conductivity than what I used.

 

So, does the sensors on this CPU pick up much higher temps, or maybe does my cooler have defective heatpipes?

3D v-cache adds about a +20C insulator on top of the die as apart of the 3D v-cache mod. They file down the whole die, add the 64MB to the centered L3, and silicon spacers ontop of the sets of cores on the edge of the CCDs.

 

If its letting you pull 110W on a hot summer day, then its operating normally. It'll reach the thermal limit regardless, especially if you're pushing it to maximum clock speeds. Same goes for 7000x3D.

 

The way around that is to delid and run it at stock. If you undervolt it just right though, it'll reach the TDP limit before the thermal limit which I was able to do with a 7950x3D direct-die cooled.

 

What you could try is lowering the SoC voltage that it normally runs at by 100mV, that might reduce the IOD power draw by a few watts and freeing up some for the CCD.

You pretty much have to go into bios, AMD Overclocking, Precision boost overdrive, Negative Offset, 25. This will help temps greatly. Also adjust your fan speed. Or use Fan control in windows

 

Otherwise expect it to idle around 40-53 degrees, thats pretty normal behavior.

 

my 5800x3D Gets up to 82 in some pretty CPU intensive games with my NH-D15 at 100% fan speed. Most games though are around 60-72

Single tower air cooler on a high end chip, nothing bad though.

 

Temps look okay as previously described on why.

 

The AM5 socket Ryzen is actually even crazier with it's thermals if you enable PBO, often seen having same temps when you swap out for better cooler, but in turn the processors then clock faster or for longer period of time.

 

AM4 is bit more tame though, so won't have significantly the same effect, but it does have PBO too of course.

 

Ryzen is a modern CPU that has numerous safety features preventing from overheating or damage, and if it's getting too hot it usually hovers few C below it's tJunction temperature, which is it's max allowed temperature.

Some AM5 Idle on higher if you have a beefy cooler.

Does your motherboard run the latest Bios? I've seen boards with older Bios versions (no X3D support) reporting those CPU-s having crazy temps, solved by a simple Bios update to a version with X3D support.

That's just how these chips run. It's normal. 

Prime95 is the worst case scenario, you can also use CO to allow higher clocks under max load but the temperature won't change in these stress tests and in gaming it won't matter. You'll just gain some multi-core performance for loads like Cinebench, Blender,... 

 

Also temps between Intel and AMD can't be compared as they have different sensors in different locations.

Oh, right, I remember seeing something about it, but didn't even think of it. I just expected it to run like my old i5, which pulled even more power than it, but your explanation makes complete sense, thanks for the info!

I also had a slight undervolt in my i5 and did some on my 3080 yesterday, so I guess I'll try on the CPU as well.

Holy, if you're getting those temps with the mighty NH-D15, then I'm good, my cooler isn't defective, it's just trying it's best haha. I expected to at least not hit Tjmax on Prime95, but I guess I overlooked how differently this CPU works.

Yeah, I noticed it has slightly lower Tjmax than non-3D CPUs (-5°C), it pretty much stays pegged at 90 while running Prime95, but seems to be pretty well managed indeed.

Yup, and funnily enough, at first I was running it with a AMD stealth stock cooler while this one didn't arrive and the UEFI was outdated by several years and the temps were fine because it was stuck at base clock.

Sorry, CO?

And yeah, I expected to see some difference between AMD and Intel, but didn't expect it to be this big, it really is drastic in the case of 3D v-cache CPUs.

yeah, also Prime95 is called a "stress" benchmark for a reason, it's not a realistic test on how the PC performs, it's a test that ensures the components won't fail when put under hardest demands.

Yup, I use it as a worst case scenario. Used it a lot in the past to validate OC, it's the best at that. But I hoped it wouldn't almost instantly hit 90°C, so I could be sure it wouldn't ever hit that while playing, but now I'm not sure. Still have to test the undervolt and some heavy gaming.

[freeagent]

I think it’s just made with bum silicon. I have had multiple samples of the same cpu that all behaved differently. I don’t not buy that vcache adds 20c because my 58X3D runs very cool.

There is about .1% chance that any game will ever stress your CPU as much as Prime95, I believe. Watch your temps when you hear your fans are really noisy during gaming.

Yeah, I tried pushing it on Cyberpunk 2077, and it didn't reach 80°C, but still, I'm not happy with high 70's while gaming. I guess there isn't much that can be done.

Lol! You could get a better cooler and UV + OC.

I just bought this one, not gonna spend more money, it is working. But I'll try some UV indeed. OC is locked on this CPU.
