Noise levels are extremely high when using Corsair LL120 fans during gaming sessions.
Hello! I have a 3 LL120 rgb fans in my case and a H100i platinum se aio. While just browsing there's no issue with them, but when i start a game and it loads up the fans instantly like blow up and start spinning like a jet engine. Things i tried: First i used a pwm splitter to keep them tidy and together but i thought its the issue so after that i plugged all of them into cha_fan headers seperately but the issue stayed. In Bios i ran the fan tuning option, didn't help. Tried to put them on silent mode. Read here in another topic that people put them on fix rpm, didn't help. After i put them on fix rpm, around 1000, it seemed okay, good temperature and barely could hear it. I launched a game, and when it loaded up instantly loud spinning noise, but in the hwmonitor software and also in ICUE the rpms didn't seem to change. How can i have very loud spinning noise all of a sudden when i launch something resource intensive without actually changing the rpms? Please help cause it is driving me crazy, can't even exist next to it because in longer term it gives me a headache. Thank you!
Are you sure it's the fans? Based on my experience with LL series fans, even when running at full blast, I never encountered any noise issues. They were among the quietest I've heard at full speed. It seems more likely the pump noise you're noticing is the cause.
The lower fans seem to be rotating much more intensely than the others. Their operation resembles a computer startup—quick spin-up, then slowing down. When launching games, they also kick up loudly initially, but stop once the game ends. We disassembled the whole system and reassembled it exactly as before; now during play it runs smoothly without any audible issues. The only issue we discovered was a small tear on one fan’s power cable, which we repaired with tape. It’s unclear if that resolved the problem, but it seems to be working now. Update: after 10 minutes and a restart, the CPU temperature reads 42°C and the fans spin rapidly again.
It's resolved... I'm not sure if going into more details would help since I'm really nervous.
She installed the Phanteks included GPU support inside the case with the RTX 2060 Super. After working there for about five hours, we noticed that out of three fans, one wasn’t spinning because it was stuck in the support. Once we took out the support, the third fan started moving and the noise disappeared. We thought it might be the AIO pump or the fans, but it turned out to be just the fan noise. The lesson learned: with the new Phanteks NV7 case, avoid using the included GPU support bracket for RTX 2060 Super cards, as it can block a fan.
