Threadripper 3960x crazy temperatures

Hi guys,

 

Please help me out. I've got a Threadripper 3960x cooled with Corsair H115i Platinum RGB and while on heavy load temperatures reach 88C and 93C with PBO turned on (max temp according to AMD is 95C; CPU doesn't switch off after reaching that level). By heavy load I mean 3D rendering using Arnold (CPU-based renderer). Idle temps are oscillating around 60C. Is that normal? I am not sure whether I'm experiencing throttling. All cores work steadily around 3.8-3.9GHz and render times per frame are stable as well. I guess that means no throttling? 

 

All drivers, including chipset drivers, are up to date as well as Windows is where it should be too. Here is the complete spec and let me know if you need more info.

 

AMD Threadripper 3960x 

Corsair H115i Platinum

Aorus TRX40 Xtreme

Corsair CMK64GX4M4C3200C16

Corsair 680X

GeForce RTX 2080Ti

Samsung Evo Pro m2 1TB

Segate HDD 4TB 5400 RPM 

Windows 10 Pro 64

 

Shall I consider switching to a bigger cooler like Wraith Ripper? Shall I invest in better cooling paste? Shall I not worry at all?

 

Thanks a lot,

Bart

Re: Threadripper 3960x crazy temperatures

You have AMD Recommended liquid CPU Cooler installed: https://www.amd.com/en/processors/3950x-thermal-solutions 

But if your idle temps are around 60C you have a problem. Those are very high temps during idle loads.

I would check to make sure your AIO is correctly installed and the water block is making good evenly tight contact with the processor. Also make sure the Thermal paste is covering the entire processor surface with a very thin layer.

I would check for Air flow around the CPU Cooler's radiator and fan. Make sure it isn't obstructed and the fan is spinning at maximum with high temperatures.

Make sure there is good liquid circulation through the hoses to and from the Radiator and water block. No blockages or leaks.

I noticed that Corsair has a CPU Cooler software. Make sure you have the fan configured to be aggressive:

CORSAIR iCUE software allows you to control and synchronize your cooler’s RGB lighting with all iCUE compatible devices, monitor CPU and coolant temperatures and adjust fan and pump speeds, all from a single intuitive interface.

Zero RPM cooling profiles in CORSAIR iCUE software allow fans to stop entirely at low temperatures, eliminating fan noise.

By the way, Corsair has a new update for the above software iCUE:

Re: Threadripper 3960x crazy temperatures

Thanks elstaci! I've played a bit with cooler's fans settings and I've managed to get a couple of degrees off the chart. Current idle states in Windows are around/below 50 C. I must add that proper idle state in BIOS shows temps around 40 C. That should be fine, shouldn't it? 

If rendering (no PBO) day to day for hours at <90 C temp should I worry about my CPU being damaged? What better cooling solutions could you all recommend?

Re: Threadripper 3960x crazy temperatures

40C seems to be a good idle temperature. But maybe another User with the same processor can post their idle & heavy load temperatures to compare.

The CPU Cooler you have, in my opinion, is fine and recommended by AMD for your processor.

Your Processor's Maximum Temperature is 95C so it is getting close to its max temperature. I would try to get it down below 85C.

I suggest you open a Corsair Support ticket to find out if that is normal temperatures for your CPU Cooler and also an Online AMD Service Request to see what they suggest from here: https://www.amd.com/en/support/contact-email-form 

Here is Corsair FAQ concerning its Hydro Series CPU Coolers: Hydro Series AIO Cooler FAQ – Corsair

Re: Threadripper 3960x crazy temperatures

I am also running 3960X with Aorus TRX40 Xtreme. And I am having similar temperatures as yours. I am using the NZXT Kraken X73, which is a 360mm AIO. When heavy-loaded, and pump, fans running at 100%, I am having around 90 degree C on the CPU.

From this post, I am seeing similar temperatures

So I think you are fine, or at least not alone.
