My velka and gpu extender (that did not come with my K39 for some reason) also got delayed do to covid, so it's still a problem. I wonder if the people with the noise have the psu out of the case or what there running to test it. I saw some one get told not to switch out the fan, but idk why people are switching them with noctua.
I have it out of the case and it is noisy on idle. It's noisy from the moment I turn on the pc to the moment I turn it off regardless of the load. Also, I have a non-k i7-4770 and no gpu at the moment, so it shouldn't be consuming that much power. I'm still looking to switch the fan but to something with high cfm.
