AirportExpensive9201 Posted October 3, 2022 Share Posted October 3, 2022 (edited) Hi, Around 1 month ago I brought H150i Elite Cappelix. I run it on stock thermal paste and it was quiet, but after changing it for Thermal grizzly one, I got this sound, This been 2 weeks ago, and still no change.Temps are excellent, it's just a noise (less then 50C in games/25-30 Idle/65 in Cinebench R23 multi-core after 10 minutes) * ALL on BALANCED settings on iCUE* I've tried pin point the problem and it's definitely pump. Thinks I've done: -Tilted PC in all directions -Run AIO on extream on it's side for more then 1 hour -Turning ON AIO without attached to socket ( same sound) -Using washers on Fans screws. Video: https://imgur.com/a/qqcuXKN *On idle pump is QUITE quiet so,it's hard to hear it on video, When you can hear the pump it's when I open up a random game ( It happens in every game/CPU intensive tasks) The only fix I found was limiting fps in games to 60-90 fps and noise is reduced by like 50% and sound just like on desktop* Also the noise you hear I can hear it, with side panels ON and 2 meters from me at around 70% of what you hear. Also the "liquid moving" sound you hear only happens when you start a game for around 20-45 sec then it's disappear. My Amazon return window is ending in 2 days. Is that noise a sign of something bigger ? I really want to avoid Returning it because I would not be able to use PC until new one arrive.

newJason Posted October 16, 2022 Share Posted October 16, 2022 I bought the same model H150i Elite Cappelix about 2 months ago and yesterday had that same noise that was coming from the pump. I fixed it by setting the pump to "quiet" mode and it stopped instantly and has not returned. It's a small air bubble that gets hung up on the pump fins. Make sure your pump is not the highest part of your cooler system. Link to comment Share on other sites More sharing options...
