I'm using the Y cable that is bundled with Coolink SWIF2-120P fan, and its quite handy and useful when using multiple PWM fans at single mobo header, see the below pic.
The right one is utilizing all 4 pins and its connected to the push fan, it has the rpm/tacho line and imo its more important to monitor the push one, while the left one for the pull fan, no rpm reading though but still controlled by the same shared PWM signal.
Actually with some minor wiring and additional fan connector mod, I could separate the pull fan's rpm wire and connect it to other mobo fan header to monitor it's speed, but I think monitoring the push one only is enough.
Also like to share a minor detail about the anti vibration pad, the standard package came with 2 types, one is those thin white silicon strip, another one is the triangle black rubber pad, found out these two are not effective and quite difficult to secure it when fastening the fan on the clip, they tend to slide in or out which is a PITA to work with.
I tried another type of pad which is a thick fabric carpet like material that has one sticky surface, this one is a lot better since its thicker and looks like they dampen the vibration better like below pic. Now all pads are replaced with these white fabric pads.
Suggesting you to add another columns at the spreadsheet with these items, since this beast is considered really wide and it should be interesting to see the trend once we have enough participants :

- Heatsink orientation : North-South (like mine) or East-West
- Orientation reason : Better performance (tested/verified both positions) or Others (this could be purely for the look or probably space constraint/limitation)
