[QUOTE="keeper11, post: 1723768, member: 379276"] Hi Razoredge No its a electical buzzing noise. I have an app to adjust the fans i adjusted from normal rpm 1100 to rpm 5500 acording to your theory at rpm 5500 the noise would be a lot higher but it is not stays the same. I have seen posts about it being a power supply fault? But it did help removing power for 5 minutes turn on again and now no noise i would like to know if people that have same problem if it comes again. [/QUOTE]
