The "Anti-Vibration rubber pins" didn't do the trick, tomorrow I should receive some rubber spacers. I will try tomorrow to add the spacers on the back (against screw head and case), since the fans do have their own rubber corners. If there is still noise, I will see if I can somehow, somewhere, place something between the removable fan grills and case, tho they feel very, very tight.
The screws were screwed firmly.
The fans only spin if I have PWM (or auto) selected.
I already have a support case running with Jack-Z. My setup:
Case: 7000D
Fans: 11 x ML120 RGB Elite Premium, 1 x ML140 RGB Elite Premium
3 x ML120 connected to 7000D PWM Repeater for AIO.
4 x ML120 connected to Commander Pro on front via Y-Splitter
4 x ML120 connected to Commander Pro on side via Y-Splitter
1 x ML140 connected to Commander Pro on back.
2 x Lighting Nodes from ML120 Triple packs are in controls of the RGB of those 12 fans.
I really love this case, and I am hoping that one day, I will be able to buy a White iCUE H170i ELITE LCD Display Liquid CPU Cooler for it...
