I recently picked up a Phanteks cooler, but wanted to swap the stock fans out. I've heard good things about it, but I wanted true PWM fans on there, not just 3pin fans hooked up to a 3to4pin adapter, and I'm a bit of a Noctua fanboy so I picked up the Noctua NF-A15 PWM
to try out on the heatsink. See a lot of Thermalright TY fans swapped in but haven't heard much of Noctuas in the Phanteks so I figured why not.
Using Noctua "Anti-Vibration mounts" provided with the fan and stock Phanteks fan clips, mounts perfectly just like stock:
The fans are exactly the same height, the mount holes are exactly in the same place.
I heard people do zipties or something similar to hold Thermalright TY fans to the Phantek heatsink, but the anti-vibration mounts that Noctua provides with the fans work perfectly with the stock phanteks clips. Instead of hooking into the hole of the stock hole mount, you basically hook onto the rubber Noctua mount.
I always wondered about those side blocky sections on the NF-A15 but I realize now that because they're the soft rubbery anti-vibration, they press up again the heatsink so they perform the same function as the adhesive anti-vibration strips that Phanteks provide.
Not even sure if I need to stick the center anti-vibration strip since the Noctua fan's side anti-vibration mounts provide a slight clearance between the fan and heatsink in the center.
Oh and in case you were wondering.. fits in center no problem too... again same size as stock Phanteks fan so didn't think it'd be an issue anyways.
