The cooling performance of Noctua fans fell below expected limits.
The cooling performance of Noctua fans fell below expected limits.
I currently have the following setup:
evga 280 clc with 2 Noctua NF A14 ippc 3000 fans.
Another identical Noctua fan on the top panel for exhaust.
One 120mm stock fan on rear exhaust.
i7 8700k and msi z370 A-pro motherboard.
It’s unusual that when I increased all three Noctua fans to their maximum, the reported RPMs stayed around 2500 for each. (I’ve connected each fan to a different header on the motherboard to verify they’re running separately.)
Ignoring noise, I wasn’t expecting such a significant drop in speed. Since their theoretical max is 3000, especially for the industrial ippc3000 model I own, I assumed only a slight reduction—like 2700 or 2800. But 2500 RPM? Did I lose something important or is there a limit in my motherboard?
Thanks for your feedback.
you must either connect them straight to the psu or adjust the rpm in the bios to maximum
You need to either connect them straight into the PSU or adjust the RPM in the BIOS settings. I connected all three to the motherboard (excluding the fan header splitter). Both BIOS and HWmonitor reported around 2500 RPM. That's a bit higher than expected, but not by much...
