Yeah, I have no idea at all why those back connectors to the cabinet were not on molex connectors in the Spooky pins. SUCH a pain to access with limited visibility.

USPS is unbelievably uneven now. Literally the worst by far in my lifetime. Cross country? Usually 3 days, but not always. but I have a few packages within California - going from N CA to LA that should be 2 days that are taking 5-6 days. Had a package coming from Montana that is 10 days and counting. The new postmaster needs to be fired immediately before it gets worse. This is insanity.

If you're rolling your own, I'd use 24awg wire, cut to length and then put the connectors on. The stock wires are usually too short and too thin for Spooky meanwell power supplies because of the long path from the fan to the connector.
You don't need thread cutting screws for spooky, only Stern. The spooky screws can be reused.

Ministry of Pinball has both my spooky and stern fan kits now and some other select items from my pinmonk.com store. Shipping to France should not be that bad from within Europe, and it should arrive quickly.

Thanks for the compliments!

I left the DIY origins of this thread here up for people that want to roll their own, but once you get the parts and pay for shipping, it's really not that much different than the premade ones I have now for US customers. Europe is another matter, which is why I linked up with Ministry of Pinball to get some of the more popular pinmonk.com items closer to European pinheads to save shipping cost and time.

And the instructions are good because I revised them a few times before release after beta release feedback and a few times after release to clarify some parts people were questioning. They definitely benefited from user feedback for which I'm very grateful. I also *hate* instructions with bad photos, which is why all the fan kits and the 3D Anubis kit have drawn illustrations - clarity.

It's been a while since I've done it, and I don't have a Spooky here to look, but I think it either slides up or sideways and off or snaps on and off. I'd try sliding first.

It really would be nice if Spooky re-engineered this to add molex connectors so you don't have to unscrew the wires from the power supply, but just plug and unplug like on Stern/JJP machines. This setup really is a failure of engineering.

In Spooky's case, I meant keep the header block design, but make a short wiring harness with Molex connectors on the other end so you can plug/unplug the power supply easily. Wouldn't have required any interaction with Meanwell to accomplish this and would have been a MUCH better design. It's essentially what Stern does on theirs.

Are you talking about for their power supply or a cooling kit for their flipper coils? Are they still using two power supplies like Houdini with the switching power supply that was an add-on later? I haven't had one since Houdini...

Just the model number of the power supply is fine. I can pull the schematic once I know the model number.

EDIT: Nevermind. It appears go be an RSP-750-48. At first glance it seems it can use 2 x SFAN-001 spike plug and play quiet fan kits, but there is mention of a "speed control function" which could be a third control line or the power supply undervolting the fans to slow them down. It also doesn't seem to have a thermal switch?? Do the fans run all the time like Spooky's meanwell power supply?

The main question is if the fans in the power supply are being speed controlled by regulating the voltage, or if they have a 3 wire connector, with one being used for speed control. But there's no way to know for sure without opening the power supply.

You could probably put a 3D printed shroud on the back of the fan and connect that to a 120mm quiet fan and just force the air into the power supply. The stock fans would never come on if you kept the power supply cool enough with the big fan. It would be ugly, but it would work.

That's definitely different than what they were using before. Going from Meanwell (which has a good reputation) RSP-750-48 with ~92% efficiency to some off-brand rando China power supply with ~80% efficiency is not a great move, but was probably inevitible given that the Meanwell they chose was $180 retail while this cheap box-ticker "it works for now" power supply is $68 retail. You can tell the cheapness/quality difference just by looking at how sparse the inside of the power supply is. This is the OEM for the rebranded power supply you have: http://www.gyuspw.com/product.php?cid=61 which you can tell because they both link to the same "best force" web site and have the same specs.

So looking at the fan leads, if the fan speed is changing, they're doing it by undervolting it because there's no speed control wire. That's good news. But I'm not even sure they're doing that. It looks like there's just a thermal switch that turns the fan on and off at full speed when the temp raises/lowers.

I can't read the model number on the fan to get a cross reference, the picture resolution is too low. Can you take a closer picture of just the fan label?

Can you take a close-up picture of the fan label so I can look up the specs?

And wow, that is one weird franken-power cube they have going there. THREE switching power supplies in it? Seems like really bad design. A 48V and a single Dual 5v/12v combo should have been plenty.

Yeah, that's SUPER no-name. Even my contacts in China and Taiwan that deal in fans haven't heard of it.

Haha, yeah. Every time a new Stern machine comes in I tell myself I'll change the fan out eventually but no rush. Got Avengers, set it up and then the fan came on and I had to change it immediately. Totally obnoxious.

The Meanwell RSP-750-48 American Pinball chose initially is overkill and crazy expensive, which is likely why they probably did a 180 and went with this no-name piece of crap power supply later that literally costs more than $100 less and SAYS it's 50w more (but that's likely a lie in the real world). Literally. That both shows how crazy the meanwell they chose was and how cheap this one is.

The RSP-750-48 would definitely need quieter fans since it has TWO loud fans (NMB 1608VL-04W-B69) that output up to 38dB when on at max together (and draw a crazy 2.6A when both are on!) vs only 15.8dB for two of the quiet fans from my kit, but the complicating factor is that unlike the other meanwells it has a speed control lead. So it would probably be a situation where you just put in two quiet always-on fans in there and just let then run all the time since you can't hear them. And that would be good anyway because at max, the CFM (air flow) is almost exactly half the two fans at max speed.

Here's a pic of the insides of the robust RSP-750-48. Compare this to the sparse electronics in the piece of crap they went with purely for cost reasons later that you have now:

It would require some more investigation, but you probably can get away with a Meanwell SE-600-48 like is in the Spooky machines and is also kind of overkill. That is, IF it would fit in that enclosure. Those can be had for like $75 and are WAY better than that VELIKA thing. I don't think AP really needs 750 or 800W of power (and the Velika isn't delivering 800 anyway, because its efficiency is crap). I think they were just trying to solve the intermittent drops in coil power by just making the power supply bigger and bigger when their capacitor kit that came later was the answer. So dropping back to a 600W power supply with good efficiency that actually DELIVERS that amount of power consistently is probably ok. But this is uncharted territory and would need some temp and power testing (by you, if you go that route, I don't have any AP machines anymore). It's definitely worth trying...

Yeah, they definitely made a running change rather than pay $180 for a way-overpowered meanwell RSP-750-48. But if you want to get that (since the AP enclosure is clearly made for it), you can pick them up used on Ebay for about $100 if you make an offer on them when they pop up. That's how I got the one I have. Then all you'd have to do is swap out the fans and you'd be good to go. Just keep a temp probe inside the RSP-750-48 for a month or so until you're sure the temps are stable with the lower CFM quiet fans. There's a LOT of overhead in this power supply, so I sincerely doubt heat will be a problem, even with lower CFM fans, in a home environment.

Spec-wise you should be fine, but the connector on that fan is too thick/large to plug into the receptacle in the power supply (if it is the same as in the picture), so you will have to cut and splice in a new one or crimp in new pins and a smaller compatible connector.

Another path you can take if you have some resistors and shrink wrap on hand is to put a resistor on the red lead of the stock fan to reduce the voltage, which will slow the revolutions of the fan blade and should reduce the noise. It's a hassle to figure out the ideal resistor to use to get the best result, but the stock fan has about twice the CFM of the fan in the plug and play kit I sell (and the one recommended in the OP), so you have a lot of overhead to work with if you want to play around and spend the least amount of money possible (i.e. you have more spare time than money). At some point the fan will not run if the voltage is too low, so there's a fine line to walk. If you go this route, please share your result!

It's probably more expensive to buy the male/female pins and connector to roll your own. They're not really economical to buy onsie-twosie. If you're not too precious about the stock power supply fan, you can cut the connector off it with enough wire left, then solder that wire with the right connector already on it onto the other fan and shrink tube the two soldered points.

It's definitely not a molex. The link I posted to the OP years ago that's NLA now is a JST XHP-2 2.5mm pitch connector. You might be able to cross it using that info.

I have the fans I sell in my kits customized at the Sunon factory in Taiwan in bulk for me, so they arrive with the right length wire and connector according to whatever spec I gave them a few years ago to fit in the Stern power supply. That's why you don't see the exact fans I sell with the same wire length and correct connector for the Stern power supply at parts places like digikey, etc. Usually it's 3 wire, naked wires, no connector, or the wrong connector or the wrong wire length and you have to work on it to make it suitable.
