I just got my 3090 kingpin finally. I'll be using the LN2 bios for gaming and benchmarks.

I'm thinking of changing the fans of the radiator for Arctic 1800rpm or noctua industrial 2000rpm. Then connect them to the motherboard to save from power from the graphics card.

Is it a good idea? How much speed should I give to the fans as they won't be controlled by the graphic card-temps?

Check out this thread for some recommendations for fans.
 

That realty the power?

For my first test session I was able to manage 2715 MHz in Port Royal and grab the #2 global spot, amazing card!

 

Woow Amazing score! Nice job!

Yes, very nice 👍😊 indeed, excellent 👌 work

Can I use the LN2 bios with the stock cooling or it voids the warranty?

Well, got the kingpin running the other day. Stock bios got core clocks of 2210 out of the box. Switched to ln2 bios, can't get it to 120% using current px1 it's stuck at 112% and can't oc any higher than 2210.

Installed firmware at first bootup of px1.

Anything I'm missing?

Might try uninstalling PX1, DDUing the drivers, and doing a clean install of everything.  Or others have had improvements using Afterburner.  (hot debate topic)

I'm having a similar issue.

I just got the card and start testing but my initial test is showing more performance with the Overclock bios than the LN2 bios.
