Hi Folks... I wanted to replace the noisy fan on my Munsters Spike2 Power Supply but also maintain the CFM (and even increase it)... but as you know, the 40mm fans have their limits if you want to stay quiet and maintain the CFM.

I made a small manifold that allows you to easily put a 60mm fan into the stock 40mm mount on the Spike2 Power Supply... the manifold uses a 'dummy' fan frame to replace the original fan and then sticks up and out but still flush with the backbox.

Here is a google album showing before, parts and after - https://photos.app.goo.gl/8DDXhdbAXgxSeUwE7

Original Stern Fan 34dB 11.3 CFM
Pinball Monk Quiet 13dB 5.5 CFM
60mm Adapter 19dB 12.6 CFM

I cannot hear the 19dB fan in a home environment and it has slightly increased cooling over stock!

If people are interested I think I will make up about 25 kits... I can do a kit with the manifold only ($10) and manifold,screws,fan ($20).

NOTE: The kit won't have a Noctua fan, but one that is actually quieter, the Noctua doesn't have a 2-pin connector so it is not 'Plug and Play' it is just one fan I used to test it out.

Can’t say the fans bother me, but nice to see an option that flows better than stock!

#3 2 years ago

I like this approach: I think keeping the airflow up is the right idea. I put that lower flow one in, and it will sometimes run constantly even in the moderate PNW when ambient room temp is in the upper 70s.

Let’s see the test results. The CFM ratings given by the manufacturer are under ideal conditions. Any given application will vary from ideal. More CFM doesn’t automatically mean cooler temps.

I have 4 manifold+dummy sets printing now... if you want to have a sample to give me feedback on, I will be happy to send folks a set for no charge.

but... 2 sets are spoken for already, so I have two sets left.

If after testing you find it insanely awesome or something, you are welcome to $ me.

These have been on ebay for several years, several insiders bought these back when the Spike 2 PSU mods first came out:

It would be nice to have a US source....

I made one with my 3D printer and posted it a year ago. There are several models available for free to print. The "2-sides aligned" is important. You want the fan to be pushed to the right inside the head otherwise the back light coming from the LEDs on the CPU board will have a small shadow on the translite cast by the fan.

And yes, it is quieter than the Pinmonk unit. It also runs constantly so it doesn't cycle heating and cooling.

Why would you do this? Seems like a lot of extra work removing the old fan for no benefit. The way I look at it, I'd rather leave the original fan in there. With the external fan there, the original should never come on and the air will flow through it just fine. If for some reason the extra fan loses power or fails, the original fan will be there for backup and you will hear it come on and know something is wrong...

The original fans are loud and crappy. They are going to fail eventually anyway. Why not replace them with an alternative that doesn’t have to work as hard and is substantially quieter?

You missed the point. Once the external fan is in place the original fan will never come on. The original fan comes on when the game heats up and runs for a bit and then goes back off again. When you install the larger, quieter fan on the adapter, you connect it directly to power so it is on all the time. The game stays nice and cool and the original LOUD fan never comes on. This way you don't have to go through the hassle of removing or disassembling the power supply to get to the original fan. Makes the install way easier.

#11 2 years ago

Where do you connect it ? inside the power supply box, in place of the original fan ? inside the powersupply but additional to power supply ?
or can you connect the fan somewhere else in the backbox (where exactly then ?) so it runs all the time ?

I'd like one! I bought the Pinball Monk kit, but then chickened out on installing it. Yours looks way more stable and less risky. I'll PM you my address, I'd love to try it out on my Star Wars table, with it's obnoxiously stupid loud fan.

I see - I wasn't clear from your original post that you don't even remove the original fan. I'd be a little concerned about the fan itself blocking airflow, but the larger fan probably spins the blades as needed, and as you said if the large fan fails, the original fan can always kick on.

#14 2 years ago

Per the connection question.... I have the larger fan cable connected in place of the original fan on the same connector, it is running down through the manifold. The smaller part of the print is simply a 'dummy fan frame' that mounts the same and blocks the rectangular holes in the top and bottom of the case lids. You certainly could leave the existing fan in there and just unplug it, but fan blade would create some turbulence and friction and really just can be removed. Alternatively, you could even leave the stock fan in there, and power the larger fan via a power connector or even the 5V on the USB slot of the CPU.

So really it gives you several options. to be honest with you, if you leave the stock fan and power the higher CFM + lower noise fan via the USB, that sorta seems the easiest. You could install the new fan without even removing the Power Supply (which you would need to do if you wanted to unplug the old fan and plug the new fan into the existing temp switched connector). If for some reason the larger fan ever died, the good old stock fan would kick in still AND you would know because you would be able to hear it screaming.

Not to be a downer ..... but if you are gonna go through all that work plus the fact that cost would most likely be equal why not keep it stock with the correct fitting part.

#16 2 years ago

I used PinMonk’s mod. I’m not the least bit worried about it having enough airflow. We’re talking about a power supply which is not only a simple circuit, but a cheap replaceable part.

#17 2 years ago

4 samples are spoken for now... they can post feedback once they get them... thanks everyone for the ideas and feedback!

He actually says why in his first sentence. If you know of an option that does these both and keeps it stock then let us know.

Quoted from HighVoltage:

He actually says why...

Installing an additional fan in a different position that may be blocked by the original fan does not automatically mean better cooling. You need test data. What are the temperatures with the stock fan? What are they with the mod installed? Are they consistently better or worse and under what conditions?

Not sure why you're asking me this stuff, I was just saying he made his motivations clear.

But as long as I'm replying, seems you didn't read his post.

#22 2 years ago

You missed the point. The original stock fan comes on and off automatically based on temperature. If a constantly running external fan is added without disconnecting the original fan it is very simple to tell if it is improving the cooling. If the original stock fan never clicks on and starts screaming, then the power supply is staying cool with just the external fan and the internal fan is not needed. Furthermore this proves the air is flowing just fine through the stock fan even though it is not running.

I have been running in this configuration for a solid year on SW Prem and the stock fan has not come on a single time.

You really have nothing to fear with the quiet fan kit you bought. I've sold hundreds of them over the last couple years and there have been zero installation failures. Literally everyone who installed it succeeded. That's why the instructions are so specific - to prevent you from making an installation mistake.

Perfect fit and cheap..... what else can ya ask for.

#25 2 years ago

I’m in, I’m sold, how do I buy a kit? The Stern fan is ridiculously loud.

Just to second this, I've installed two of them. It's a great kit, works fine and really makes a huge difference.

Im still getting the new manifolds send out the the 4 folks that grabbed the 4 samples so I can get get feedback. Finding a 60mm fan to with direct USB wiring is a little more challenging than an 80mm so I am still looking for best fan options. I will start putting the manifolds up on Ebay here this weekend if folks want to get one and source their own fan.

As other posts have said, the stock fan will never come on with this one running (it will come on if this fan either fails or if the power supply overheats for some other reason), but the upside of the stock fan not coming on is that the stock fan is horrendously loud in a home environment and is quite annoying as it cycles every five minutes for 5 seconds.

Im just trying to share options for everyone since I personally find the stock fan to be loud and don't want to disassemble my power supply to replace the stock fan with the PinMonk kit. The PinMonk kit *is* a perfectly fine and great upgrade tho... Im not trying to detract from that in any way. This is just different.
