What do you mean 520C? I didn't see anything in your screenshots
Typo edited, 52°c...

But after CPU-Z (75°c), i tried SuperPi, Prime95, Linpack, certainly Linpack according to you could do it, with the good settings, it even didn't esceded 50°c durant bench of all this three tools.

I prefer Linpack Xtreme, the 10GB load vs p95 small ffts. I heard the opposite is true for Intel, but from what I remember from running them, is that Linpack still got hotter and used more power than p95.

I know for sure it isnt Cinebench lol :)

I've never understood how most people get idle temps so low on the 7800X3D. I'm thinking it's just my boards default settings that pump more voltage than it needs or something. My idle temps have always been noticeably higher than I see most people get, but my load temps are absolutely fine so I don't care, but it's just weird and mind boggling at the same time haha.

In a 23º room right now it's 45-48ºc, but if I fire up CB23 it stays under 80ºc. So my cooler (in my specs) is working fine I'd say.

My paste is MX6 :


My A.F III is 240.

Linpack, probably

Prime95 makes no sense on Ryzens without access to PBO (ie. for increased power limits)

Anyway, all are CRAP, only CPU-Z reached 75°c in less than 30s-1m, LinPack Prime95 stops at 50°c, obsolete for 7800x3d it seeems.

Benchmark Scores I once clocked a Celeron-300A to 564MHz on an Abit BE6 and it scored over 9000.
I'm asking for my brother. :) He currently runs a R5 5500 under a Wraith Stealth, and I'm wondering if that cooler would be enough for a 5700X3D, considering that it doesn't come with one.
wraith stealth i would say no, sure you can find him a really cheap 20-30 quid tower fan like even the old cooler master ones would be way better. not sure if those are still around anymore. have pity on his soul and help him get a thermalright one for 30-40 quid :D
IME direct heatpipe contact doesn't work as well as a soldered baseplate on AM4 where you have hotspots and need thermal mass as well as something to spread the hotspot to multiple heatpipes rather than overwhelming one or two of them.

The cheapest decent AM4 cooler that I know of in the UK with a baseplate is the TR Burst Assassin

@AusWolf tell your brother for 15 quid, that link there that is the cooler i'd go with, that beats a wraith stealth all day. and i am sure you could rig a second fan in push/pull easy enough for even bang for buck with a spare fan.

I am using MX-6 as well. Tried other pastes too. I'm going to try with less paste next time and see. I think I might be adding a bit too much.

But after CPU-Z (75°c), i tried SuperPi, Prime95, Linpack, certainly Linpack according to you could do it, with the good settings, it even didn't esceded 50°c durant bench of all this three tools.

Mine is similar. R23 stock scores are low, clocks and power and temps are all relatively low.

Like I said, 7800X3D is a hardlocked CPU. Stock PB algorithm is very aggressive at reducing clocks/power in power virus workloads. Usually can be completely circumvented by a bit of PBO, but again, hardlocked CPU.

I've never understood how most people get idle temps so low on the 7800X3D. I'm thinking it's just my boards default settings that pump more voltage than it needs or something.

Kinda hard to tell without more info, it's not truly idle unless your Windows is very clean in terms of background programs. Mine at idle behaves similarly to the 5800X3D, truly idle usually in the 30s and just doing stuff in the low 40s.

Only difference at idle is that the 7800X3D has SUPER low per-core temps, like, exactly ambient lol. Most likely not what's actually happening but AMD sensors are always so enigmatic so who knows

Also, if you are just running XMP and your board has really high auto VSOC, then that might dig into your idle temps. I'm running like 1.1V. Could go lower but then iGPU starts flickering

Anyway, all are CRAP, only CPU-Z reached 75°c in less than 30s-1m, LinPack Prime95 stops at 50°c, obsolete for 7800x3d it seeems.

Then maybe just loop R23 then, if you only need a temp stress. Shouldn't be drastically affected by PB algorithm pulling power. Mine is somewhere in the 75-80C region, CO doesn't seem to affect temps in any way.

yeah honestly I've chalked it up to just background apps and maybe high default voltages. As I said, under load it works fine so I'm not worried, just curious I guess.

how high? out of curiosity

In general I don't think I've seen the 7800X3D exceed 1.06V idle vcore or so. I don't remember Vcore under load but iirc it probably wasn't any higher than that either, at -35.

Also, Florida :D can't be that cold there

i don't recall right now but as far as temps it's under 80ºc PBO or not. Hits full clocks on all cores. and yeah, room is 26ºc now so yeah hahaha, tad warm.

I'm surprised y'all can even use PBO. I have to set my CO, then revert PBO to disabled - main PBO setting set to anything but Disabled/Auto completely nukes my system, everything is ultra slow like the CPU is limited to 0.1GHz.

Not like conventional PBO is supposed to do anything to 7800X3D, but still

That's weird. For me PBO is hardly any difference so I just leave it off. Extra heat for not a noticeable difference.

Haha no she just ignores me.

She just spent a weekend in the states with her GF and came back with a shitload of junkfood that we dont get here. I am not really into junkfood so I bought myself a 1000w PSU without batting an eye and it felt glorious :)

As for the heatsinks.. well.. back to my little EVO again haha.. my air cooling setup is quieter like this than when using the AIO.

I've never understood how most people get idle temps so low on the 7800X3D. I'm thinking it's just my boards default settings that pump more voltage than it needs or something. My idle temps have always been noticeably higher than I see most people get, but my load temps are absolutely fine so I don't care, but it's just weird and mind boggling at the same time haha.

In a 23º room right now it's 45-48ºc, but if I fire up CB23 it stays under 80ºc. So my cooler (in my specs) is working fine I'd say.
My 7800X3D is currently sitting at 47 °C under a Dark Rock 4 with its fan stopped. My CPU fan curve only starts at 60 degrees.

Okay, wraith stealth is taking it too far :D

I am running the 5800X3D just fine under a AXP120-X67 right now. It is limited to 88/60/90 for obvious power supply reasons, but in the 80-90W region it does just fine. I reckon 5700X3D will be more than fine if you can get to a Black Ridge level of cooling.
presumably it cools exactly like a 5800X3D at any given PPT. It's the same silicon, running the same power. The clocks are irrelevant because the heat comes solely from the power being pumped through the chip.

I believe both the 5800X3D and 5700X3D share the exact same 142W PPT from their "105W" TDPs, so they will be cooled identically, or at least within margin of error.

For a non-X3D chip, I would say there's a chance that the faster CPU's boost clocks reach higher points on the freq/voltage curve, resulting in higher hotspot temperatures for 1/2-threaded low loads at max boost clock, but the X3D chips have a strict voltage ceiling, so I doubt there's much difference between the 5700X3D and 5800X3D, if any.


I had a 5800X3D running in my HTPC with a Thermalright SI-100 for a while, where noise levels mattered a great deal in a relatively restrictive case. I ended up just setting a 75C throttle point which stopped the CPU from reaching its fastest single-core clocks, without lowering the PPT. When the heat is spread out over an all-core workload, 142W PPT isn't that hard to keep cool.

Doing some testing I found that single sample of 5800X3D basically hit diminishing returns at about 110W PPT, so if cooling is limited, you're still getting >95% of the performance from a 5800X3D at PPT=110, TDC=75, EDC=115
wraith stealth i would say no, sure you can find him a really cheap 20-30 quid tower fan like even the old cooler master ones would be way better. not sure if those are still around anymore. have pity on his soul and help him get a thermalright one for 30-40 quid :D
Thanks, guys. :) He's not currently thinking about an upgrade, but considering that Kingdom Come: Deliverance 2 has just been announced, I think he will be soon. :D I'll make sure to get him some cooling as well.

My 7800X3D is currently sitting at 47 °C under a Dark Rock 4 with its fan stopped. My CPU fan curve only starts at 60 degrees.

I usually never get on my PC right after waking up which we've had the A/C running all night. So my ambient temp is never really low. Usually upwards of 23-24ºc . So right now I fired up the rig after waking up A/C just shut off, and ambient temp was 21ºc. Browsing TPU and with some things open in the background it's at 40ºc and it's not entirely idle. So I think my issue is just a combination of high humidity, high ambient temps and the fact that I run my fans relatively low to have a quite PC.

Sounds about right. I'm usually at 38-39 when browsing, on a 19-21c ambient.

I run my T30s at a fixed 1300rpm but fan speed has never really meant much to X3D.

yeah that might be it for the most part. I run my fans at 950RPM's, as you said doesn't make a whole lot of a difference in temps and it's nice and quiet.

There's nothing wrong with that. :) Like I said, my CPU fan doesn't even start spinning below 60 °C. This gives me around 47-48 °C idle with a 21 °C ambient.

no I know, but was just curious why most people report such lower temps but I guess really in my case it's just ambient temps mostly.

5800X3D also had a pretty big spread in sample variation as to temps (presumably due to internal IHS contact). Since AM5 heatspreader is regarded as being even worse performing, that might still be in play.

What's your VSOC and SOC power at?

Very true, this is the only 7800X3D I've had in my rig so really can't compare to others.

Holy crap! I think that's the highest SOC power I've ever seen from a 1CCD CPU :D I'm used to seeing those numbers on 5900X

auto VSOC must be pretty high then, that certainly explains higher idle power and a bit higher idle temps. Core powers are probably because you're doing stuff with your PC, but SOC should not change much unless under heavy memory/memory controller stress
