Posted September 5, 2015 Hi guys! I've been subbed to Linus for a long long time and now i have registered to this community after all this time. I have just built a new rig and after couple of days my Seidon 120v v2 started acting weird... loudly... it produces this ticking/humming noise which is loud enough to annoy me enough unless i use headphones. Even if i turn on my fans to full speed it's still louder, it's hard to enjoy games or movies with it being so loud. I've done some research, but haven't found a solution to this, so i came here for help. I went to BIOS where i checked and the fan control panel said that the CPU FAN is running around 2320rpm while the Fan included is going around silent 780rpm. Changing the modes helps for a bit, but then starts again, but not as loud and the sound is a bit different. The cooling block is connected to the cpu_fan and the included fan is connected to cpu_opt. I made a little video about my problem, sorry for the bad quality since i dont have surgeon hands. https://youtu.be/nEx_2tP6HJw CM Storm Trooper Maximus Hero VII i7 4790k 4ghz GTX 660 8gb 1600mhz HyperX RAM Seidon 120v v2 SATA 500gb W7 64bit Ultimate - UDM Link to comment Share on other sites More sharing options...
