As the title says I'm not entirely convinced about my new graphicscard upgrade. Went from 670 DCII to 780 DCII because I was so happy about my old card and it's inaudible cooler, but this new 780 DCII just isn't. While I'm gaming I don't mind it but when I'm browsing the internet and not doing anything stressful the card still makes noise. I wouldn't call it 'noisy' but it sure isn't silent in idle. The card itself is running remarkable cool at 27 C and the fan speed is set manually to lowest possible (1130rpm @ 37%). I've inspected the card but everything looks perfect, the sound isn't mechanical, it's just a static air "whoosh".
How can I lower the fan speed further? 27 C is overkill for me, I'd rather have it silent like my old card.
