Setup hwinfo and RTSS, kind of time consuming but it is nice. Probably on Sun evening we'll start loading the content apps and get to hammering it with some real loads. I need to take some final shots too I suppose. Also, this loop is configured to monitor water temps and not cpu temps, to balance between cpu vs gpu rendering.

Nice build, congrats.

Post some AS SSD or CrystalDiskMark results, it'll be awesome.

I'll hold myself this time and keep my 2950x for now, avoiding the "upgrade disease" :p.

A 1500VA UPS can't even handle my 9900K@5.0GHz with a custom loop and an RTX 2080 Ti. There is no chance it will handle a modern HEDT CPU.
I recommend using a 3300VA for safe margin, also an online double conversion nobreak would be nice :p

It hit 10gb/s read and 15gb/s write. I haven't bothered to try and match Giga's settings for the 15/15 results. Currently priming "safe" ryzen calc timings but after I can run crystal.

Tested at their settings and cannot hit the same speeds. It's averaging 10/12 gps up to 10/15. The card gets pretty damn hot its definitely throttling to some degree.

I might testing removing the shroud and slapping on a fan.

Here it is sans shroud. The heatsink gets really hot to the touch. I ended up adding a 120mm fan to it. Btw, pro tip the heatsink screws are under the huge thermal pad, so peel it back and you can unscrew the heatsink.

Temps dropped from 125f+ to just over 100f-105f. And that is just idle. A few runs with the shroud on and its heatsoaked. There is a 120mm fan on the sink which is not in the pic above.


Finally broke the 15K barrier on both R/W. Results are somewhat varied and can't quite match Giga on other tests, but its close enough I guess for early days.

The whole build log should be pushed at all the content creators forums and /r
Should have its own YouTube playlist.

It's like a new Volvo commercial truck pushing X more loads of trees, rock, etc.

Just set a standard people in this gen of TR and gpu can point to.

I'm wondering how much headroom you need to let the TR3s sit all day wide open throttle.

Someone with an open loop and a pile of rads should start us on a cpu loop only at 280mm and find where saturation is. Then other guys are to that table with respects to voltage and where static core behavior maintains steadiest state.

Threadripper is not hard to cool imo, you just need enough cooling capacity. In this rigs case, it has two 480mm rads with two 2080ti. It is admittedly on the low side for capacity given how much power the 2080tis draw when overclocked to 2k/2k ish mhz, and even so the temps are decent. Now once we start talking about high all core overclocks, then yea you will need even more cooling.

I can tell you now. I used to run a 3900x and 2080ti on 3x120mm

GPU was In the 50s loaded cpu 60s loaded for gaming.

On my 3960x with same 2080ti now on 7x120mm, a 3x120 and 4x120 I'm seeing full GPU load at 45 max cpu hovers in high 30s to mid 40s gaming.

So even a 3x120mm could at least cool an am4 and GPU. So I'd say about 4 to 6x120mm should be enough to cool 2 gpus and a cpu. Also block quality etc... matters. No way a single water cooler user could do a project like this unless he had a lot of time. I'm not going to do it.

The old math and it still applies because rads are rads are rads at the end of say is 1x120 is good for 100 watts.

So a 300watt cpu and 300 watt gpu should be around 6x120mm worth of rad then you want the extra 1x120 for overhead. Hence why I have 7x120mm for my system. If I added another gpu I would be fine because even if GPUs are loaded to 99% your cpu is sitting at 5 to 15% pending your running a Ryzen 3000 series which can feed a GPU and yawn at it.

But you should build your system as if all parts were running at 100%.

This sucks for TR3 builders that are stuck btw less performance and air coolers or aios that have issues with their cold plate efficiency.

My Eaton 800 holds a PC with 3900X + Vega 64 at full speed (not Oced) + 1 FHD screen (from 2 used) + a fiber optics/ethernet converter + internet BOX + router/wifi + DECT phone. No problem as there shouldn't be because it won't make more than 800W TDP all together. The PSU is 850W but it's because I like to oversize the PSU (650W of quality should be more than enough).

Basically, the total power output of my system with monitor is over 900watts, which is all the UPS can do. It can do 950w for a brief moment, but that's it. If I move the monitor off of it, the thing should be fine but I haven't done that.

All these low watercooled temps have inspired me.

Think I'll go with this for my 3970x:

1 EK XE 360
2 EK PE 360
1 EK Revo Dual D5 + EK-RES X3 150 Lite (I like the idea of things still being cooled if a pump dies, as I have had AIO pumps die in the past)
1 Heatkiller IV Pro Acryl Nickel-Black (sounds like this one might be slightly better than the EK block?)
1 Ek-Quantum Vector RTX RE Ti D-RGB
Soft 9,5/15,9 tubing

Will be going into my 011 Dynamic XL case (the XE on the inside, PE's on the top / bottom of case)
3x 360 radiators are probably overkill for right now, but I plan on getting one or two of the next 3080 ti gen cards if they support HDMI 2.1, so will be nice to be able to support that, and maybe an 8k samsung or the 4k120 C9 OLED's for my desk....

I'd end up doing side, rear, and bottom intake with top exhaust.

Be interesting to see whether the 3rd rad causes flow issues or contributes any meaningful capability.

It's also nice that we don't have to go with collectors item caseelabs or behemoth thermaltake cases to cram in multi big rad cooling.

I'm still validating the memory but I did manage to do a Timespy Extreme run.

View attachment 207199


I gotta say, TR3's IMC is pretty darn sweet. Running 4x16gb at 3600mhz with tight timings with cpu at stock atm. It's averaging 60c in P95 with peaks up to 85c.

*Just ran R20, got 16870.
You tripled my 3900x score. Damn now I need to get a better job so I can upgrade. Lol

I almost slapped this into the loop but we decided to not go for a 24/7 all core overclock. I used to run two of these back in the day... As it is, you should see the water temp pwm curve, its a real extreme ramp, from 27c 30% pwm to 37c 100% pwm. 34c is where the water usually is under sustained loads and that's at 52% pwm max efficiency of the 35x.

hi smokingman,

could you say something about your temperatures after constant 32core rendering for 30-60min ?

i just finished a much simpler 3970x build using a Noctua NH-U14S TR4-SP3 mounted with thermal grizzly conductonaut.
out of the box (no overclocking) my temperature raises in seconds but doesnt seem to exceed 76C
i'm new to this and i'm not sure if it is wise to let it run with 76C for hours..

best, index

I've got the same heatsink on my 3970x, gets too hot for my liking running it at 100% and way hotter with the case closed, so I recently ordered some water cooling parts.

yes, i feel the same... (76C with case closed here)
did you try a 2nd fan? from what i read an aio is not really better(?) ... could you post your selection?

Yeah using two of the noctua fans in a push pull configuration. I read the same on AIOs some of them are even worse than the noctua heatsink, so I ordered parts for a custom loop with a heatkiller IV block.

Hmm, temps wise under prime95 avx blend cpu temp averages 65c however peaks get up to 85c. Under sustained rendering temps stay in the low 70s, and we're talking about sustained loads that can run many hours. In most daily loads cpu doesn't peak above 65c. However, monitoring setup with hwinfo64 displays average temp, not peak temp. And we are monitoring by water temp but this is by design. Not sure how you guys are doing it but you're probably looking at peak temps that flash by. In benching and gaming I didn't see cpu temp get over 60c often.

in hwmonitor i get some strange max values of 85C which i cant read on the actual temp display. maybe those are some super short flash peaks.
i rendered in cinema4d for 40min and the temp was at 76C all the time.
if those numbers are right you get exactly the same peaks and about 5-6 (only!?) degrees less in sustained rendering.
hmm.... if this is really true i invest first in a 2nd fan for the cpu cooler and more fans for the case....
(did you use thermal paste?)

Maxxon's physical render engine doesn't tax the cpu temps very much, mid 60s iirc. It really depends on the load, which renderer, gpus involved, etc etc.

I should add that fwiw, at stock in cinebench for ex. temps are at mid 60s max. Switch to an all core overclock of 4ghz and temps hit 70c and change. When I bumped that up to 4.2ghz all core, temps hit 82c. I didn't go higher but that is enough to see the scaling. Also when debauer was clocking 4.5ghz before delidding, he hit 85c in cinebench. His temp falls in line with the scaling I was seeing.

my main question here is how much you can get out of custom watercooling...
cinebench is too short i guess, it would be nice to know what temperature you get with 30-60min rendering in cinema4d (in stock)
(i took one of the R21 example scenes in the browser and cranked up the resolution)

i guess the main factor is the effectiveness (size) of the radiator?
what frame is that in post #100 :):)

There’s very little thermal mass in a custom loop and doesn’t take long to saturate at his wattages. After a minute or two he’d know his temps. It is very reliant on radiator sizing.

Of course this is different if someone is using a large external resevoir, but that is uncommon.

yes... it seems an internal custom watercooling doesn't cool it down more than to a ±65C range ...
guess only a separate, external 9x9 radiator is able to cool it down more
the question is... how bad is the ±75C range for the processor?

Where are you getting this? Again, you keep throwing numbers around ignoring the context.

What do you mean there's little thermal mass? There's a lot of water in two 480s. The water is the thermal mass. And it takes minutes to heat up the water temp.

i was referring to the temps for stock in #108. but u're right, sorry about polluting your thread w newbie questions :whistle:
Here's a simple test for you if to get a sense of your cooler. Run prime 95 avx blend, you will have no stability issues at stock obviously. But let it run for at least 20 minutes. Then note your cpu temps. If you get up to the 90s or higher, you don't have enough cooling.

Blend makes your system unusable to the point you can barely move mouse to turn it off. Be careful when using it. What may seem unstable isnt but blend takes control like a virus at least for me. Small fft should be perfect for temp testing and blend for general stability.

That's cuz it uses up 99% of the memory. You can see it eating it all up at the top of hwinfo.

You reply so fast I don't have a chance to edit typos ha! You gotta slow down man Haha your as fast as an AI :-p

You sure you didnt install those nvme raid 0 in your brain ??! Smokingman here has a 3970x strapped to his medulla oblongata

At 95c the chip throttles down.
