ZOTAC RTX3070 Fan 2

[PCEnthusiast]

Ayy up, Just want to pop this in here as i have noticed this with these Zotac dual fan coolers.

If any of you experience this noisy fan thing on the Zotac twin fan coolers its usually down to the cooler plastic touching the heatsink somewhere and at certain fan speeds the plastic fan shroud will vibrate against the heatsink.

Typically you can wiggle the plastic around and change where the sound is coming from, or completely get rid of it, The mounting isnt as great as other cards, but after its moved around a bit it usuallly wont come back, If that does not work then of course get a replacement, But for the more tech savvy folks, its worth taking the card out and giving it a wiggle and a good look to see if theres any visible places where plastic can touch the heatsink.

Just posting this so it can help other people with 30 series Zotac twin fan GPU's and probably other brands too.

PCS kindly replaced my faulty palit 3070 to a zotec 3070.

Whilst the GPU works;
When the GPU temps low enough, the fans stop working (makes sense).
Then a second later the temps on the GPU go up a degree or two (assume due to the case heat...).
Then the fans kick in, the GPU cools and the fans stop.
Then a second later the temps on the GPU go up a degree or two (assume due to the case heat...).
Then the fans kick in, the GPU cools and the fans stop.
and on an on....and the fan profile is very limited.

Wouldn't be so bad if you couldn't hear the fans rattle around between the transition of 'on to off'.

My solution has been. Change the fan profile so they are on all the time. Maybe I'll give 'the wiggle' a go and see what happens

stick them at 60% or so and should be quiet and good thermals

It's the "freeze" feature, you can disable it in firestorm, or the way you've done it now.

How can I enable/disable fan-stop on certain graphics card models? | ZOTAC

<p>The FREEZE fan stop is a feature available only on certain models. Look for the label or FREEZE badge on the packaging of the graphics card or on the product page or product brochure.</p> <p>The FREEZE fan stop feature is automated and is enabled out of the box. There is no user interaction...

So - The freeze option doesn't work. So

I put in a custom curve meaning fan 2 is always on (Interesting it doesn't appear you can do it stepped as in the photos)

Alas. Problem is. Firestorm never remembers the custom curve! I have firestorm starting up with the PC - and on fan two it 'sometimes' starts with the custom curve, then something forgets. Code for - annoying fan 2 rattling about.
