The idea is to make minimum changes to the machine but still takes the overall experience a step further.I think the majority of the noise is coming from the fan grill. Basically, I just repositioned the original cooling fan, and 40mm is quite commonly available if you desire to use a quieter fan.

On top of existing screws and nuts, you still need, M3 T nuts - 2 M3x14mm screws - 2 M3x8mm screws - 2 M3 washer (optional) - 2 rubber/silicone rings to soft mount the fan (optional) - 2
