Is this temperature normal behaviour of W6800X Duo or any other Graphic card ?

Hi,

After reading amazing post of all of you I jumped and bought W6800X Duo and now need some help to understand and see whether my W6800X Duo is defective and need to ask a replacement or refund.

I am just testing a video footage from pixabay and applying just NR to see how is my GPUs behave.

My MP spec is 28 cores, 3Gpus, (W6800X Duo, W5700X and 6900XT eGpu).

The reason eGpu is the card RX6800XT Sapphire SE was bought before I get my Mac Pro and the measurement was wrong. It was stated something on Sapphire webiste but actual measurement is different.

Anyway, The project is here and you can download and see, of course if you have time. PROJECT ZIP FILE TO DOWNLOAD

I am just applying some NR to the footage and see how my W6800X Duo behave as follow in Davinci Resolve.

I am using 3 monitors and the following will shows how I attached my monitors to Graphic cards.

Before fans kicked in, the Temps reached to 90-95 but after fans kicked in, the temps stay in 70-77.

I am using with Resolve 17 and just getting 16-20 FPS and choppy footage. I am still playing the footage for now about 20 minutes and temps are still between 70-77. But fans speed are as in attached image.

Just saw a post that someone saying Resolve is not using more than one GPU but I can see all my GPUs are cooking properly. I am sure he may got more experience than me.

Is it normal ?

Am I getting defective GPU ?

Please kindly help me to understand if you are using same or different GPUs about this behaviour.

I am not sure how to contact Apple Support to ask this question as the applications that I am using ( TG Pro from TunabellySoftware and iStat Menu from Bjango ) are not made by apple.

Thanks in advanced.

Mac Pro, macOS 12.2

it is not surprising that it may reach a very high temperature for an instant. The only problem is when it STAYS at a very high temperature, and does not cool off into a more normal range.

I see nothing that indicates you have any temperature iisues in nay of these cards. they are phenomenal compute engines, and get hot, but cool themselves off and continue to do your work.

Now that you have looked it over, I suggest you continue to test the new expensive card by removing the others are running only on the new card.

All the numbers you posted look just fine.

Your Mac is working hard, and the temperatures are remaining modest. Your GPU temperatures are far from the maximum 100 C, and the fans are running at only half of their top speed.

I expect only ONE of your GPUs is working on this editing, and the others are idle. I do not know how to tell which one is active.

Thanks.

But it reached to 97Degree though. Is it something I should be worry ?

It is stated "Maximum Recorded Temperature 97 C"

Regarding the GPUs usage,

According to the iStat Menu which I am using right now showed that all GPUs activities of processing under each GPU section.

I just check again as I am not doing any editing and all GPUs' processing activities are very minimal.

That's where I assumed all my GPUs were cooking.

Is there a way to check which one is using ?

Sorry to bother you though. The GPU card cost more than a car and cannot afford to get faulty one.

Before anything happen to my MP my heart might stop.

Regards

Thanks a lot for your kind explanation.

I tested my Sapphire RX 6900XT SE and its fan also kicked in to full speed within a few seconds.

I am happy to know that my GPU is working as normal and thanks to you.

Really appreciate it.

Best Regards
