Ok here’s my write-up for the PinMonk fan kit install. I have also installed his kit for my BKSOR Prem since rhag upper right flipper causes mega over-use of the right coil and the coils are wheezy after 30-45 minutes. For TBL, as soon as I started beta testing 0.89, the game times went from 5-7 minutes to 20-30 minutes due to the add-a-balls. I then started to notice coil fade and Walter became tough and other shots just lost some zap.
In comparison to the older style kit with the 3D printed housing, these are very nice. I had to melt and carve and cut away a lot of the BKSOR 3D printed fan housings to fit and not hit stuff in that machine. For TBL, this Tibetan Breeze style kit fit perfectly with no issues.
Sound-wise, I’ll admit that I barely hear the BKSOR fans (there’s three of them in there), but you can hear them if you listen purposefully. For this TBL kit with the new fan setup, there is no way you hear anything with the cabinet and coin door closed up. You can hear them if you open the coin door and put your head a foot away. Super quiet.
Anyway, on to the install. As usual for me, nothing just installs easily and, I took my time, but it took me a couple hours.
One important disclosure. I have 1) cpr9999 ’s harness installed on my game, so you will see that additional wiring in my images 2) I have a trough light so you will see that wire in some images.
First, maybe some TBL machines are different, but the only problem I noted with the instructions are in step 1, where I believe the clip referenced to piggy-back onto is incorrect. It mentioned the right clip, but on my machine it’s actually the left one.

Next three picture are the flipper mounting plates we need to remove. I found it way easier to work after unplugging the yellow coil power clips. Pay attention that the coil return springs are mounted to the farther hole. You need to know that to remember where to put the spring on the fan mounts, since there are the same options.

Here was my one hour time suck. The LAST of the flipper plate mount screws was cross threaded by the factory…and cross threaded hard. My hood Phillips bits were chewing the soft metal of the screw head and making things worse. It was so cross threaded that the plate could wobble around even through the screw was “tightened” all the way. It wasn’t actually gripping down flush. I ended up cutting a cleaner cross pattern into the screw head and then soaking it in WD40 (one drop on one chip of a board ). I couldn’t apply heat like I normally would since the coil paper and wood and boards are all really close. Finally, standing on a stool so I could apply hard pressure right back against it while fighting it, it budged. I was one step away from using a removal bit to rip a trashed screw out, and that either ruins it more or works.
Anyway, that was not fun.

Installing the fan mounts is fairly straight forward. The only issue is, due to the bracket, you can’t really go straight at the screws to install them. You’re sort of going at a 30° angle, so be careful not to mash up the heads of the screws. Use a good proper sized sharp bit (P2).
After installing and putting the springs back on, everything seems good. The right bracket is pretty tight with the flipper coil harness wire. Nothing really to do about that but I set mine where I think all the wires will be fine. They do touch though the bracket, and nothing can be done about that.

The rest is just ticking and zip tying wires. I was a bit confused about the 3’ extension in the kit (not a big deal but the instructions mention 4’, while it’s 3’). I think the whole kit would work fine without the extension. I had it installed first without it and it was all done and I was left staring at the extra wire extension. Just in case it helped with lifting or moving the playfield later, I popped that in-line.
I found what I feel is the best way to route and secure and tuck the wires. You might feel differently. A bit different than the instructions, but I recommend starting right at the flipper fan mount wires and securing there and working back to the backbox.
I also highly recommend doing it right and tucking the wire near the backbox into the factory gray plastic loom so you don’t have a random wire dangling around.

Excited to get a long game going this evening and see if I notice improvement. I’m sure I will, sense the kit makes night and day difference in my BKSOR.
Oh and before it gets mentioned, yes I clipped the ends of the gold zip ties. I left them that way for the pics so it’s easier to see.
