hello guys

I recently upgraded my 5600X to a 5800X3D. My understanding is that this chip due to the v-cache design runs a bit hotter than a 5800X per say. Now I won't compare it to my 5600X as that was a Ryzen 5, this is a Ryzen 7, so more cores, etc. CPU is the only thing that changed. It's cooled by an Bykski CPU block, to a Bykski distro plate with two EK S360 rads. the GPU is in the loop, it's a 3090Ti but my understanding is this should be enough cooling for both.

So idle is about 45ºc then if I put it under 100% (Prime 95 Small FFT's) it goes straight to 90ºc and stays there. CPU doesn't throttle, but should it not be running cooler than this under water?

The way this distro plate works is RESERVOIR > PUMP > GPU > RESERVOIR > CPU > RESERVOIR > TOP RAD > FRONT RAD > RESERVOIR > PUMP and so forth. that's the routing. Only thing I can think of is that after coming ouit from the GPU it doesn't go through a radiator and it's already hot? my GPU is running great. Idles around 36ºc, full load stress test 58ºc.

Originally I did have an EK block on, so when I installed the Bykski block I re-did the thermal paste obviously, switched to Thermal Grizzly Kryonaut Thermal Paste which is what I have on the GPU. I've tried loosening the CPU block, tightening. Are these temps normal?

Thanks in advance for any help guys.

Your CPU block is either improperly pasted or mounted. A custom watercooled CPU shouldn't be running that hot.

My 5900X (the one in my System Specs) maxes out at 63 °C during a Cinebench R23 run. And that's on one of the warmest days of the year. My GPU will max out at 65, two degrees above the CPU.

Both my CPU and GPU idle at 33 °C, again on one of the warmer days. So your 5800X3D is idling and peaking at higher temperatures. Your CPU should be idling around 36 °C -- the same temperature as your GPU's idle.

I use HWiNFO with graphing turned on.

Yeah something is off but with EK Block, same thing, with the Bykski block, same thing. My 5600X was mounted on the same setup and block and didn't have this issue. So not sure what I may be doing different? Issue started since I put this CPU. GPU is perfectly fine, actually running super cool.

Yeah something is off guys, going to have to reseat again and see. I did when I changed blocks so not sure what the issue could be. I'll give it another go and report back. I am also using HW info. peaks at 90ºc all cores :(

hope not lol

Are you using the PBO2 Tuner program? That should help, and you will gain some mega hurts too :toast:

So many threads on this lol

5800X was thermally the worst Zen 3 CPU.
5800X3D has even worse thermals. Expect straight to 90C for most all-core workloads. There is no comparing to other Ryzen 5000 CPUs (Ryzen 7000 maybe).

Water isn't guaranteed to help, especially without a newer block made with these CPUs in mind (Optimus, TechN, Velocity2). Peeps been complaining about these older blocks on OCN too and how they don't help tame 5800X3D.

If you want to bring down the temps (and see if the contact is the problem), use PBO2 tuner to do your Curve Optimizer and set some lower power limits. eg. all-core -30 and ~100W should cut temps by 10-20C, if contact is not a problem. You shouldn't need more than 120W to achieve max all core performance at 4450MHz.


Isn't that with an ambient of sub-20C or just around there? Little chilly :D

Exact same experience. Stock: Straight to 90c for me on a NH-15 and FC140. With Negative 30 on all cores, rarely see over 80c.

The 5600X is a 65W TDP part, it can be cooled with a mediocre 120mm AIO. It wasn't stressing your custom cooling loop at all.

Since you have poor cooling with both EK and Bykski blocks, it might have something to do with the routing configuration with your distribution block. I have no experience with distribution blocks so I won't make any suggestions. And you correctly pasted your GPU so it's probably not a poor paste job.

For what it's worth my loop is: Pump > Reservoir > CPU > 240mm Radiator > GPU > Inline thermal sensor > 360mm Radiator > back to Pump

so the hot exhaust coolant from both CPU and GPU are immediately being cooled down.

Unsurprisingly the coolant temp during idle is the same 33 °C as the CPU and GPU. Maxed out, the coolant temperature is 53 °C right before entering the 360mm radiator. I know people here get really passionate about cooling discussions and I tend to stay away from them these days. Regardless even if I'm doing everything wrong (which I'm sure some will enthusiastically point out), my temps are fine.

Anyhow best of luck.

It's 3C outside but pouring rain..... don't think my PC wants any of that :laugh: snow tonight but probably no accumulation yet

One of my buddies bought a grow tent for his PC either to expel exhaust heat or bring in cold air from outside.......

Sometimes I forget that @freeagent sits next to a jet engine every day. We start out at similar ambient but mine climbs closer to 25C later in the day

I am surprised how much the 5800X3D's behaviour is similar to Ryzen 7000 thermals. CO by itself does not so much, power limits by itself does not so much, combined it's a world of difference. I think I shaved off between 15-30C depending on situation and about 35W max power. Having PBO back is a great experience.

Your CPU block is either improperly pasted or mounted. A custom watercooled CPU shouldn't be running that hot.

5900X is not a good comparison. Water barely affects the ST temps/spikes compared to air. Water shows its advantage with higher wattage, but only where thermal density is acceptable.

Haha no honestly this is the quietest rig I have had for quite a long time!

All of my settings are in that screen cap above, the 66cfm fans on the cpu were at their full speed of 1500 revs, the stock front fans kind of have a bit of a howl sound at full speed, they are the loudest. I do have a TY-143 on the rear of the case, but it is limited to 2100 revs and its no louder than what is already going on. Honestly, the best air cooled setup I had was in my Meshify C loaded with iPPC 3K fans, no rear exhaust fan needed but it was insanely loud if you let the fans spool up. Almost 700CFM going through it was effing awesome lol :laugh:
The 5600X is a 65W TDP part, it can be cooled with a mediocre 120mm AIO. It wasn't stressing your custom cooling loop at all.
The 5600X with PBO and custom power with curve can do in excess of 130w PPT, and over 150w PPT with a static clock.

How much power consumption stock for all-core? 120W ish?

If -30 all core (if you can do it stable) + something like 88/60/90 doesn't immediately make a huge difference to temps, then I'd revisit the mounting question. 25C is fine. It's about 25C here right now.

Honestly even without changing power limits, -30 alone should make a difference.

Its 19.5c in my room right now, in the winter though it can dip down to 16-17c. If I open a window, I can get it down low enough for me nervous about things that keep us alive in the cold Haha. The closer you get to 0c the heat pipes don't work as well so there is a balance. If you are moving a lot of air it seems to put a chill on the sinks that makes it easier to keep the hot bits at bay, but there is a limit that is unique to each setup. I kind of want to try to find some industrial 180x38s that will run at 12v. 250-300cfm each would be fine :laugh:

Thats all I do with mine, just give all cores -30 and let it have its power.

Hey guys so using PBO2 TUner I set it to -30 and then the PPT to 100W and max temp is 70ºc without even cranking up the fans. So going to stress test for now and see if stable so atleast I don't have to tear it down right now to reseat the block, etc.

Sounds about right for a block at 25C. I doubt fan speed helps much, it's water and there's not much actual wattage, just density.

You can adjust power to your liking, just keep in mind that all-core clocks stop scaling at 4450MHz. Only BCLK can go further. So adjust power as necessary to max out at 4450MHz, and make sure there's no major clock stretching (discrepancy between Core Clock and Effective Clock during test) or performance loss.

It's best to find a combination of PPT/TDC/EDC that works well. Adjusting PPT alone doesn't always work too well for actual performance. For the 15k run I think I used something like 100/65/90.

the sensor on the block says the water is 34c, that's pretty warm I'd say. Just finished a run though. I will play around with it, see what settings work best, but atleast for now i'm not scared it'll melt off heheh

hello guys

I recently upgraded my 5600X to a 5800X3D. My understanding is that this chip due to the v-cache design runs a bit hotter than a 5800X per say. Now I won't compare it to my 5600X as that was a Ryzen 5, this is a Ryzen 7, so more cores, etc. CPU is the only thing that changed. It's cooled by an Bykski CPU block, to a Bykski distro plate with two EK S360 rads. the GPU is in the loop, it's a 3090Ti but my understanding is this should be enough cooling for both.

So idle is about 45ºc then if I put it under 100% (Prime 95 Small FFT's) it goes straight to 90ºc and stays there. CPU doesn't throttle, but should it not be running cooler than this under water?

The way this distro plate works is RESERVOIR > PUMP > GPU > RESERVOIR > CPU > RESERVOIR > TOP RAD > FRONT RAD > RESERVOIR > PUMP and so forth. that's the routing. Only thing I can think of is that after coming ouit from the GPU it doesn't go through a radiator and it's already hot? my GPU is running great. Idles around 36ºc, full load stress test 58ºc.

Originally I did have an EK block on, so when I installed the Bykski block I re-did the thermal paste obviously, switched to Thermal Grizzly Kryonaut Thermal Paste which is what I have on the GPU. I've tried loosening the CPU block, tightening. Are these temps normal?

Thanks in advance for any help guys.

I don't think it matters but you can try swapping CPU and GPU in your loop.
RESERVOIR > PUMP > CPU > RESERVOIR > GPU > RESERVOIR > TOP RAD > FRONT RAD > RESERVOIR > PUMP
My understanding is the CPU and GPU temp deltas with the water are so great that the order doesn't really matter.

With a 5950x Ryzen master typically shows my temps under 40c (36c on idle but I got things boosting in the background) HWiNFO64 says I average 46c with my ambient approx. 28c and my loop temps 31c with my fans running only 50% at 1000 rpm and D5 pump at 60% speed. Exhaust temps are 32c and with higher workloads the ambient to exhaust delta might get to 12c difference. This is probably a very apples to oranges comparison but CPU 45c (kinda) idle with 34c water temp doesn't seem that to bad to me. Increase your pump and fan speeds to lower the water temps I suppose. If you have some stuff in the background boosting try closing them and see if your average CPU idle temps improve.

I have 2 temp sensors in my loop out of curiosity mostly. A cold side (before CPU/GPU) and hot side (after CPU/GPU) and for the most part they stay the same (within error) with at most a 2c variance if I lower my pump and fan speeds too much.

Something you can try when using PBO (with or without curve optimizer) lowering EDC a bit (even when raising PPT) can knock down CPU temps a little. This was something I read in a past conversation here on TPU - that excessive EDC just puts more heat into the cpu - and I had the same experience.

Oh man @Chicken Patty , there is something amiss on this man! Probably better pull that CPU and send it right over to me for further testing...........For at least a year or so............ :laugh: :peace: :laugh: :peace:

On a serious note, something for sure doesn't sound right man. Have you tried a decent air cooler, just to check differences?

Water temp does sound a little on the warm side for running a few CPU tests at 100-120W. An hour of CPU tests would get me up to around 31-33C on a 142W 5900X, I only had a 280mm XT45.......however, my ambient was also about 4-5C lower back then when I was on the loop, and I ran probably a higher pump speed than you. Taking into account 25C it ain't bad, also dunno what your 3090 Ti is contributing to the loop at idle. eg. reviews said multi monitor idle on 2060 Super was like 20W but in reality closer to 45W (the GPU I had in that loop).

The Bykski AM4 blocks all seem to have chunky fins - Optimus Foundation or TechN that have much higher fin density might have an advantage. Not sure about EK. Also the Bykski fins are oriented west-east, so only like 20% of the fins actually flow over the CCDs (although, 1CCD like 5800X3D is just hard to cool, Optimus or TechN really aren't much better, maybe 1/3 of the fins at best).

But your CPU temps seem just fine after CO and lower limits, wouldn't worry about it as long as it's still handling the 3090 Ti properly.

On 5800X3D, the core (which gets hot) no longer makes direct contact with the IHS, only the uncore (which doesn't get hot) does - hence the bizarre behaviour. As long as you're comfortable with your temps you don't need to worry much, core clocks matter a lot less to the X3D than other Zen 3 CPUs.
