I've recently acquired a Strix 4090 OC, and I can't get the 0dB fan feature to work under any condition.
From official ASUS response in similar topics I've found that:
According to confirmation from relevant departments, the conditions that need to be met to trigger 0 dB mode activation are a temperature below 50 degrees, and it will be disabled when it exceeds 100 watts.
This doesn't seem to be the case in my experience, as even after a fresh Windows boot with nothing running, temps well under 50 degrees Celsius and power well under 100 watts, the fans are still fixed at 30% (1000 RPM). My monitor is a 1440p 144Hz panel, and I've also tried putting it on 60Hz mode just for the heck of it, still no good.
Additionally, while investigating this I noticed that my 4090 will never go below ~60W board power draw, even while sitting idle after a fresh Windows 11 boot. Is this normal for this card? I've seen other 4090 owners from different brands claiming they see as low as 5-10W power draw when idle. In a related topic in this forum another user showed that their Strix 4090 sits at 15W when idle.
Has anyone experienced this with their 4090 Strix OC? I've checked task manager and don't see anything using the GPU. Also, while it would be nice to reduce the idle power draw, from what I understand, these conditions (60W, <50°C) should still be enabling 0dB fans.
