quadro all fans suddenly stopped

Sunday, May 2nd 2021, 8:40am

Noticed all the fans attached to my quadro suddenly stopped. 10x120cm fans. The quadro is 2 weeks old.

I went into the aquasoftware and noticed all fans on 0 rpm. I then immediately hit restart, and even before it was done restarting (at the windows shutting down part) the fans started spinning again.

Thanks for any answers.

Update maybe its the "Hold minimum power checkbox"? Ill try that.

Yes, 'Hold minimum power' should help, because your water temp is 27,74 and your "Startup temperature' is 28, yielding zero on the Controller Curve.

You have an extremely narrow allowable power range for the fans (45% to 60%), so your controller has 45% power as the minimum (which will be 'hold'), to 60% at full speed.
I have my fans at 20% minimum with hold (never stop), and 100% max... not that that design is definitive, but it works the way I want.
