How aboot putting a picture of them installed?

Ahhh that's what they look like. Thanks!

Not trying to cause a ruckus, simply asking: do these coils typically get that hot??

I haven't noticed any issues with Godzilla, but Stranger Things and Iron Maiden definitely have flipper fade for me (proper tele lock shot becomes difficult on STh, and the middle ramp from the right flipper on Maiden becomes difficult before one game is over [may need to check my coil stop on that one]).

What’s the difference between these https://pinmonk.com/products/tibetan-breeze-2-flipper-coil-cooling-kit?

These are cheaper

Are they as good or better?

Good question but I think we need a 3rd party for that one.

We need an endorsement from vid1900 !

What's the longest you have had a set of these running? I would be a little concerned about the mounts breaking at that angle joint where the fans mount. You have a lot of mass on the end of that moment arm that will be subject to a ton of vibration.

Also....does GZ use different coils between the left and right side?

cool little upgrade and love the effort to record the temperature stats.

Silly question but has anyone tried putting 2 fans on the back bottom of the cabinet - one sucks in and other blows out to cool the cabinet void

Just an idea as one fan may cancel out the other and not reach the front of the cabinet.

You could possibly combat that with a 90 deg elbow on the blow in intake like a bit of plumbing tubing with a 100mm / 4 " extension pointing to the front of the cabinet (and you could have a drop in slot for dust screen if you wanted as well).

Yes, but a distant second to structure design and maybe third to material choice. If it survives a reasonable amount of time live testing, then you are golden either way. It's just the first thing I noticed looking at them and thought I would pass along the thought.

I can't say I've ever gotten into a cabinet bottom and said 'woah, the ambient heat in here is tough!'

It's just a huge volume of space with little gear generation.

I'd much rather prefer two fans pulling out of the backbox. Man, it gets toasty in there sometimes.

Can/will someone just sell the stl file so we can print our own? I'd be willing to pay for that

I can vouch for the importance of fans on the coils for Stranger Things. I’m a huge PinMonk devotee though, so I’ll always buy his stuff even if it’s a little more. The dude is an essential-mod idea factory.

But you copied the fan model and power setup right down to the diode and fuse on the power lead. Fuse is SOMETIMES, rarely done with powered mods, but rectifier diode is the one you can't explain away. No one does that to my knowledge except my kits. You just ripped mine off in a less-than fashion.

There are a MILLION things modders can use their talents for to benefit the community and make pinball better. Make something. Ripping off what already exists doesn't move the needle for making pinball better.

Oh boy, kinda thought this was coming. I only came to chime in that these fans are a solution to a real issue on some games. Nothing worse than having an epic game only to have solid shots die up a ramp and drain SDTM.

Never would have imagined a competitive market in pinball cooling fans.

Just curious if this issue with coils getting hot is a design flaw of some kind with the circuit and could be avoidable at all. I dont remember wpc games having this issue but could be weong.

Available. Check thingiverse.

Stern uses coils with one winding, and for the hold they use a lower duty cycle to reduce power instead of a higher-resistance winding. This design goes back to at least LOTR in 2003. But for a lot of games it’s not an issue. I used coil heat sinks for Iron Man and LOTR, and they worked okay. But they don’t work nearly as well as the coil fans. I consider it an essential mod for Stranger Things.

Geez dude, it’s a frickin fan. This does not look good on you. You’re a good guy and have a solid reputation and brand going at a premium price, let it go. When you’re selling $200 DC fans people are going to want a piece. Competition is a good thing for consumers so I wish you both the best of luck.

Personally I would buy the cheapest thing that works, if I was too lazy to order fans off amazon and do it myself, that is.

It’s why America is the greatest country in the world.

While I don't disagree with you in general, and PinMonk could have responded better, if it's something more detailed as he suggests, it would seem fair to bring attention to that part.

While it makes sense to see another option on the market, with pinball being such a niche hobby, I could also understand feeling like some camaraderie was broken.

I've been doing this for far longer than you, but never monetized it. I can seriously come out with a $25 fucking pinball fan kit for three flipper coils and make a clean $10 bucks-EASY.

You are not doing anything special get over it. Let this man point fans at flipper coils and charge us less than you.

SlapDrain I like the graphs, what hardware do you use for your data logging?

I feel we had the same thing 10-15 years ago with mirrored balls.

Here is what data was missing to help understand

I mean...yeah probably took some ideas from you. We all are an STL file, 3d printer, and some motivation away from doing what you do. This person is just filling in the gap between the items listed above and your high prices. (Not degrading your work, you make great mods!) As a consumer, I'm going for the cheaper item that does what I need it to.
You business model needs a change (lower prices or introduce something that this person does not) otherwise sellers like this will meet the consumer half way.
Again, absolutely no disrespect to you or the work you have done. I love your products

Is it though? Really?

YESSIR!

Yes. Like on stranger things premium LE, you’ll literally not be able to make the demo or the lock without them if you play longer than 20 mins.

The captain marvel ramp on AIQ is the same. Not possible after only 30 mins of play.

Backhands become harder on most games when they heat up (AC/DC, GNR, AIQ)

Same issue. Ever been to a herb style tournament? Theres a reason everyone tries to play the sys 11s and WPC games early in the day. By the end of the day the flippers are much different.

Looks interesting. Due to my lack of skill, my games rarely last anywhere near long enough to make this a problem but cooling the coils makes sense. A few questions come to mind:

- Are the fans on all the time the machine is on or just when a game is being played?

- Are they plug-and-play or are any wiring mods required?

- If the fans are on all the time, how noticible is the noise?

I don't wanna point fans, but this isn't very monk of you.
