As it happens, I built this exact combo a couple of days ago. What I did was:

  • shift the fan over by a few mm to avoid hitting the back of rear panel wifi
  • make sure that the fan clip was between the sticks of VLP RAM
  • very slightly bent the pipes on the cooler so that heatsink was exactly parallel to the base (the end of heatsink furthest from the bent pipes originally had about 1mm less clearance than the other end)

Removed the motherboard supportive backplate (5-screws). Now I see two screws securing the WiFi enclosure. But even after removing two screws, the WiFi enclosure is still stubbornly attached?? I put it back together and stopped there.
Nice try!
There must be some de-soldering to be done I guess, but that's indeed not something we like to do to our beloved mobos!
I will see soon if I face the same problem with my freshly arrived ID-Cooling IS 60 Evo.

Well the 120mm fan (Noctua NF-A12x15 PWM) only cost $20 so I bit the bullet and filed a notch into the side of the fan to accommodate the protruding WiFi enclosure on my (GIGABYTE B550I AORUS Pro AX) mini-ITX motherboard. I am very happy with the results and I consider this a successful Mod!!

I used a hand file to create the slot and then a box cutter knife to clean the shavings. I do believe that the structural integrity of the 120mm fan remains intact after this mod. Now the 120mm fan is able to fit flush against the VRM heatsink and fits perfectly under the Alpenföhn Black Ridge fins.

Here's three pictures that show;
  1. Fan Mod
  2. Fan fitting against the VRM heatsink
  3. Fan Cable Routing; (note) Sorry about leaning CPU cooler, CPU not yet arrived/mounted.

Nice cut, there is indeed still enough frame left on the fan, no worries.

However pics 2 and 3 seems to show the fan resting on the VLP RAM on a higher position than the opposite side (fan not parallel to the motherboard).
The flexibility of the heatpipes should add some tolerance and it should be ok, but make sure that doesn't prevent the base of the cooler to have a proper contact with the CPU.

Oh yes sorry, I recall now you mentioned it earlier.
