ROG Strix GeForce RTX 4090 OC Edition fan connect question

Hello All,

I've had  a RTX 4090 OC edition for a while and doing a bit of reconfiguring on my current pc. I have a question regarding connecting fans to the two fan headers on the card and controlling them. Do I have to download GPUtweak in order for any connected fans to work and to control them? Or will they work with something like MSI afterburner and work with the fan profile I have set in that for the regular GPU fans? Thanks

P.S. Amazing card!

Hello maintainin

Each Fan Connect II header supports up to 1 amp.

The fans will work just connecting them to the fan connect II headers, but to control them and set a fan curve, you will need to install GPU Tweak III.

You can control the fans or set a fan curve based on cpu temp or gpu temp.
