The Noctua D14 sounds louder compared to the Cooler Master 212 Evo. Is there a problem?
I just purchased those coolers for two computers, and I was surprised by how noisy the Noctua model is compared to others. Especially when the biggest fan spins at 1300 RPM, the noise level is much higher than with the default Antec GX300 fans or similar models. It gets even louder at 650 RPM, though it's still a bit better.
From what I understand, it maintains a non-overclocked i5 6600K Skylake at around 50°C during a Prime95 maximum heat test for an hour, with the room temperature at about 22°C.
I wonder if this is normal or if there might be an issue. Could it be a defective unit? Are there other factors contributing to the noise? My case is small, but I could hear it clearly when the side was open—it definitely doesn’t touch anything, and the larger 140mm fan is quite loud.
What do you think?
It seems this approach should work temporarily. You might also want to install PWM fans to let the motherboard manage RPM. The PWM fans that would fit as replacements are the NF-P12 PWM (120mm) and the NF-A14 PWM (140mm).
Are you experiencing typical fan noise or is there a sound resembling worn bearings or vibrations? The DH-14 is expected to operate quietly without heavy fan demand.
Checked the BIOS settings and noticed some unusual behavior. The 140mm fan connects to CPU-OPT on the MB, while Normal and Silent modes run at 600rpm. At maximum speed it reaches 1200rpm. The 120mm fan is always connected to CPU FAN and stays at 1300rpm regardless of settings. Can you find a way to lower it? Is this a known issue?
This might clarify things. Do you have the splitter cable included? If so, try connecting both fans through it, along with one header, and check if the RPMs align.
I installed the Low Noise adaptors and connected the fans using the Y splitter. Even though I used the CPU FAN pins on the MB, I can't adjust their speed from the BIOS anymore, so I think it's no longer necessary. The noise has significantly decreased and both fans are now spinning around 900 RPM.
