Make your PC quieter after a full rebuild in a 4000d Airflow. Here’s how to help!
you usually don’t find a quiet setup in an airflow case—there’s often a lot of gaps and openings, even where it doesn’t make sense. it might be overdesigned or hastily planned by someone in charge. i’ve seen some reviews that mention this, but most cases are built for positive pressure with three exhaust fans. that’s usually the standard. you’d typically need 3 to 5 intakes and a rear exhaust, not a bunch of odd placements.
if you’re unsure about your specific setup, try adjusting the fan positions a bit and see how it affects performance. for the fan curves, it takes some time to get it right—keep testing and tweaking until you find what works.
personally, i follow a basic rule: idle fans run low but not too low, then ramp up near the cut-off temperature (like when the pc is under load). i use a fairly steep curve around 100% at 90°C. my front fans usually spin around 900 rpm at that point, and the rear and CPU fan follow similar patterns but start a bit slower. it’s not perfect, but it helps.
experimentation and paying attention to temperatures are key. it’s definitely a learning process.
The issue is that many users, including most manufacturers, struggle with setting a fancurve. NVIDIA, in particular, has a common misunderstanding—believing it should increase gradually and slowly. This approach can cause heat buildup and ultimately lead to a hotter, noisier system than needed. I suggested keeping the fan speed lower during idle, which is also the most challenging part because once the system gets loaded, it often switches to a quieter mode. This usually results in a more silent operation compared to letting the heat accumulate with a weak curve. If this makes sense. ; D
