Fans occasionally producing sounds and slowing down during startup of a PC.
Fans occasionally producing sounds and slowing down during startup of a PC.
Occasionally, after restarting the PC from sleep or hibernation, or simply at the beginning of the day, I experience a noise from one of my front intake fans and a slight slowdown. This fan was previously included when I relocated my system to a new case about a month ago; the case itself is functioning properly. It doesn’t stop unless I power off the PC and restart it again. The fan operated perfectly in the old case.
Do you know what might be causing this issue?
Here are the details of my setup:
Processor: OEM Intel Core I7-12700KF 8 cores/16 threads + 4 cores at 3.60GHz, 25MB cache (without graphics), 125W, LGA1700
Cooler: Cyberpowerpc Deepcool Castle 240EX Argb AIO Liquid Cooler with anti-leak tech
Cooling Kit: Deepcool Castle Aio Liquid Cooler Retention Kit (LGA1700 & LGA115x)
Fans: Cyberpowerpc Dual Addressable Digital Argb 120mm Fan, 3 pins, plus two fans included for the Airflow 5000D case
RAM: G.Skill Trident Z RGB Series 32GB (2 x 16GB), 288-pin SDRAM, PC4-28800 DDR4, 3600 MHz, CL18-22-22-42, 1.35V
Storage: 1TB WD Blue SN570 PCIe NVMe M.2 SSD and Samsung 970 Evo Plus 1TB NVMe M.2 SSD
GPU: Zotac 4080 Trinity OC
Operating System: Windows 11 Home Advanced Digital License
Case: Airflow 5000D
Power Supply: RMS 1000x Gold 80 Plus
Motherboard: ASUS Prime Z690-P Wifi DDR4 ATX Wi-Fi 6, 2.5GbE LAN, 4 x PCIe X16, 1 x PCIe X1, 3 x M.2 SATA/PCIe LGA1700
What kind of sound is this? Think about how fans start at a low speed "X" and then adjust based on data like temperatures and RPMs, reducing speed when needed. I assume the first warm-up brings things up and the later stages better match fan speed with temperature changes. There doesn’t seem to be a clear reason to slow down unless there are specific issues causing errors. Probably it’s just normal behavior influenced by components, case, and surroundings. As long as everything is functioning and updates are current, the noise should be acceptable.
light buzzing noise, u can hear it here

here . I haven't had any issues while gaming, so I guess its not too big a deal. but i just want to make sure that the current noise problem isn't something to worry about
Case
This appears to involve a pattern of resonance and vibration. If you lightly place your fingers on the exterior of the grillwork, does the sound alter? Or does touching outside make a difference? Ensure all screws are completely and securely fastened for the case and fans—no loose ones. Consider applying some small strips of electrical tape here and there to absorb or reduce vibrations. Alternatively, placing the case on a rubber pad could be beneficial. The main goal is to pinpoint the source of the noise and develop a method to stop or lessen it at that specific spot. These adjustments can be reversed if needed.
Yeah that's my situation
I'm certain the sound is coming from the middle of the fans. I've also verified that the noise frequency decreased slightly as the fan speed reduced, even though the fan typically doesn't slow down after about 20 seconds after turning on.
The fans affected by this issue are connected via SATA to the PSU, along with an RGB controller. However, I don't believe connecting the RGB controller on the same SATA cable would lower the power supplied to the fans.
One of my front intake fans has been making noises during startup, and I thought a pin in the Molex connector might be the issue. Is there a solution to fix this? Also, does it matter if that pin is bent even though the fan wires pass through two pins that aren’t bent? I attempted to remove it now because the two connectors are stuck together, but they don’t seem to come apart easily.
Which pin? You can share a picture by uploading to imgur.com and posting the link.
(Likely need to swap out the fan.)
Oh ok. Still makes me wonder what makes the noise from the 1 fan. It happens like atleast once or twice a day when first boot or when awakening from sleepm then after I shut down and turn it back on, it's fine
