Hey everyone.
I’ve postet my built a couple of months ago under “threadripper workstation build”
I recently have some concerns about CPU temps…
During a MakeTx process (texture mipmap/conversion) under Houdini with Arnold Render it peaks to 95°C.
All other tasks like rendering ect are aprox between 70-85°C. So perfectly fine for these CPUs.
Iam concerned, will the CPU protect itself from burning up?
I can’t see any lowering in frequency on Hardware monitor or under task manager.
I also checked 3 different monitoring softwares. They all report a close value +-2 degree Celcius.
Should I change a fan ramp? Where should I do this? Bios or this weird armory crate software?
Specs:
Asus sage wifi trx50
AMD 7970 x
Noctua str5 14uh cooler
7 case Fans…
You should have the cooler pulling air from the front of your case and exhausting out the back. Not top to bottom of vice versa. Looks liked you may be pulling heat in from the GPU lol
I’d also make sure that you have good thermal paste coverage on the CPU.
Example:
And here is Noctua showing which way to orient the fans.
Hope the above helps get the heating problem reduced.
Apreciate your help, but it might be you’re not up to date to the current cooling solution from Noctua for TR CPUs. These Coolers are used vertical among a couple of users here.
The GPU was a 1070 before, and now a 4080. Both are doing nothing under rendering but output a desktop res.
I can render in Vray and Arnold at the same time, peaking at 86°C which is fine. Or run Stresstest, the Noctua does its job ok, not fabulous, but for these Power ok. But that specific Maketx task is killing it.
I think the problem is more related to the specific task. As on puget system tests of their Aio vs the noctua uh14 cooler there is no real difference except on certain tasks (unreal light map conversion ect).
Btw, same result with case open, and fresh startet windows. It can’t be heat radiation or sinked temps.
On your postet image, the user perfectly transfers radiation heat from GPU to the cooler.
Yes, thermal throttling’s been a thing for quite some time. The thresholds are well documented (95 °C for Zen 4) and you can measure its extent by looking at how much clocks and package power fall off.
I believe target temp for Ryzen 7000 series is 95c, and so likely Threadripper 7000 is the same. Ryzen 7k tries to boost as far as possible to hit this temp regardless what cooling you have, so the better cooling the more boost you get. My Threadripper also does this same behavior. Those are default settings from what I remember. Often times people set the thermal target down to 85c instead, and also tune voltage curve down to give lower voltage. The goal usually being to hit the stock boost performance at lower temps and power.
Good to know. Do you run custom fan curves? I don’t know how to safely set them and where. I saw something in the Bios…
For now iam just trying that turbo mode. Which is a raised fan baseline as far as i can tell.
Yes I use custom fan curves. It runs around 500-600rpm at idle on the desktop doing web browsing and scales up at certain temp ranges and runs at 2500rpm when under load and is at above 75c (any gaming or rendering load I do). I dont know where the option is on your asus board but my acer one has a whole fan area with a gui to select things and apply them to different fan headers and the VRMs.
But my fans also run on radiators, so my 500-600rpm is still plenty of cooling. I have 2x 480mm, 2x 360mm, 1x 240mm, and 2x 120mm radiators all with fans on them. lol. And yes, the CPU still runs at 95c with all that. I am going to add a secondary loop with a custom TEC setup to chill the main loops water as bit sometime this summer as a fun little project. So that should add even more cooling potential on it all, but I still expect the CPU will hit 95c. Probably just being able to get something like 5.9-6GHz on it instead of the 5.8ghz I get now.
Wow that’s a huge amount of cooling hardware then. Hm and still runs so hot. Ok.
But do I get this right that the CPU can’t die /be damaged when I see f. W 95° or 96°C?
Today no matter what I did it won’t get over 91° But was kinda chill weather today.
