Fan issue on Asus RTX 2080ti Turbo

[stevenwiner]

Hi all

Hoping for some advice here.

I bought a Asus RTX 2080ti Turbo Exhaust fan version card on Carb which I use for gaming and some casual mining when not using the PC and it is doing something strange.

When starting the system from cold, the fan either does not start up at all or starts at between 30% and 47%, but does not increase speed with temperature.

Once the card is hot (around 80 degrees), if I restart, the fan starts up immediately with Windows and runs normally (currently at 79% with the GPU at 62 degrees mining Ether or around 75 degrees playing Cyberpunk at 1440.) Once in this state it is perfect until I restart from cold again.
If I stop mining or playing a game, the fan speed stays at 79% and the GPU runs very cool.

If I restart at around 60 degrees, the fan will run at around 60% but not speed up as the GPU gets hotter.

So essentially the fan starts at a speed relative to the GPU temperature at startup and does not adjust from that fan speed.

I have tried Afterburner and Asus Fancontrol with no change to this characteristic. On Afterburner for Eth mining, I have set the power limit to 60% and dropped the core by 200 and it runs great and cool.

Fan connector seems to be in place correctly.

Any advice before I RMA this card. It works, but clearly something is not 100% and it is a bit irritating.

Has anyone experienced this before?

Seems like a busted fan controller?

Thanks @HolyCowImAnoOb That makes sense.
I was hoping it might be a BIOS or software issue to avoid the whole RMA thing with the shortage of stock, I don't want to be without the card for a long time.

I'd plug in a 120mm fan onto the GPUs PCB and see if that fixes the issue. Sounds like a fan controller though.

I'd keep the GPU until just before the warranty expires and then RMA it - It'll take months to get a replacement.

Find out the warranty details and go from there.

If anyone wants to make me an offer on this card, I will look at R15k.
Distributor does not have stock for an RMA right now, so I am happy to sell as is.

Someone snap it out of his hands and RMA it, quick.

Resuscitation this post. If anyone has a waterblock for this card, it would be a steal at R15k.

Why not G12 it, will probably cost less than 1k in total if you can find a compatible 120mm AIO?

I'm bridging the fan pins and running a small resistor so the fan just runs 80% all the time. Actually surprisingly quiet.
