My RTX2080 Sea Hawk is anoying me with the fan sound, when playing fan moves faster and this become even worst but also happens on idle...
I decide to open and investigate, you can actually see fan slow down near stop blades and then ramp up again. Now imagine listen that anoying inconstant sound all the time...
I tried with other fan, and same happens... However the blower (FAN0) doesn't suffer from that problem, so i guess the fan controller is not well designed.

I have made two videos, one from HWmonitor showing RPMs, and other from oscilloscope at RPM line, the 100% is never 100% by some reason, i guess msi not following the intel spec as i found a resistor about 20Kohm pullup from RPM to VCC, and maybe not using a open drain collector? Most fans are 25KHz at PWM line and we are observing 27KHz.
Tests was made at fixed 100% fan speed at MSI Afterburner, but lower speeds or auto speed does the same problem, a 700RPM variation at max speed.





I attach GPU-Z screens:



There's a newer BIOS that i can try?
Need to find a solution as this is unsportable at higher fan speeds. I wish i can hook to MB headers and select dGPU temp at bios, but not possible :( Use CPU or fixed speed wouldn't be optimal.
Would like to know if others have same problem with this GPU

Please MSI Team look at my oscilloscope data

You will need to add the card's S/N to check

You are using an outdated vbios (NV371MH.140). Latest is NV372MH.142. Try that: https://forum-en.msi.com/index.php?topic=313486.msg1796148#msg1796148

Thank you, i've updated successfully but RPM problem presists :(
I've contacted MSI.

Hi,

 
I just bought a new MSI RTX 2080 SEA HAWK X Hybrid last week, SN 602-V372-35SB1903000620, BIOS 90.04.23.00.70, and have the same exact problem:

.mp4?dl=0]https://www.dropbox.com/s/dt8k85ugnzxajs2/MOV_0955%5B1%5D.mp4?dl=0

Is there a known solution?

Also, wouldn't updating the Video BIOS void the warranty?

If you have sample problem, that may mean they have a design error on the regulation, my card was from first batch. BIOS will not solve that as i already tried, in fact if problem is on hardware side there's no fix, and they need do a revision of the PCB.
Thats a annoying and stupid problem, i guess many if not all users had this problem but they aren't aware because when playing with headsets is almost unnoticeble, still that can affect performance because fan is always stop and go. If you use fixed high speed is a nightmare.
The only solution is attach fan to an motherboard header, but that fix only the heatsink fan, the blower still attach to the GFX, blower is what you will hear more since it have the more dB (SPL). Even if you attach to the MB you can't link fan to GFX temp, which is not optimal.
I fell like pay for a broken premium product. They have problem's on design and not following the intel spec. I didn't go futher on testing and disassembling, but if they have both PWM headers on parallel that is enough to cause the problem.

Here the MSI anwser to my ticket:

Dear Sir/Ms:
Thanks for choosing MSI!
Glad to be of service.
Regarding your concern,

Our graphics card and the public version of the graphics card design is basically the same, may be some subtle things on the difference, but this does not affect the performance of our graphics card. Our graphics cards have been thoroughly tested many times, so you can't worry about that. Regarding the fan speed issue, the fan speed is set inside the bios, the fan speed will change with the temperature, if the fan speed is not normal, you can try to use the MSI live update software update video card bios and drive, this may be helpful. If the fan speed is abnormal, has affected the normal use of the graphics card, please contact the retailer in time, the video card repair, thank you

Best Regards
Have a nice day.

Only generic talk, they will of course ignore this "minor" problem, even with proof with oscilloscope on PWM line they don't brother to go deeper, that will imply costs and a loss.
Funny they said Our graphics cards have been thoroughly tested many times and they never spot that cheap problem, better, the multiple guys who design the regulation part doesn't follow up the norm/iso

PS: You better return it if this is a big "no" to you, and grab other product. There are better hydro solutions with dual rad but price might be higher. Or DIY kit with reference card

Thanks for the quick reply, sn4k3PT!

Your Sea Hawk was manufactured September 2018, and mine was in March 2019, so it is probably not from the first batch? Or maybe the issue is still not fixed...

I've asked the vendor to exchange the card, but I have a feeling I'll get more of the same. Sea Hawk costs much less than other hybrids, so I will probably keep it anyway.

Connecting the fan to the mobo is a good solution (also for lowering idle RPM's to below 1,000), but I'm also considering flashing the VBIOS with one from here - https://www.techpowerup.com/vgabios/207705/evga-rtx2080-8192-181012

Has that been tried with this particular card?

You can keep try with vendor up to getting one that don't have the problem. I notice my problem a little late, when i attach two fans to the radiator.
Why you wan't lower RPM than 1000? GFX on idle is unoticeble with 700/1000RPMs. Well you can disable fan up a temperature but i'm not a big fan of semi passive on that kind of product.

As i told, it may not be related to bios (software), you can try, but be carefull, wrong bios can put your card unusable
