Fit it just like the mod is, linearly aligned with the fan ducts aka on top of the heat-sinks.  The idea of the mod is to get most air through the heatsinks rather than escaping through the sides and top.
I am assuming here that it is a temporary fix as card-board can be a fire hazard IF the the dreaded S5 overheat bug hits you.

Ok - so I've fit it pretty well I have to say. On top, its going from the very front, under the cpu/mobo, then all the way to the end. The bottom is similarly covered to the mod, without the bulge obviously.

Temps are 64° / 60°, so unfortunately it doesn't seem to have helped.

I live in a very hot country and during the day there's no A/C so room temp will be pretty warm, not sure if I'm comfortable leaving it running if I'm getting these temps in an AC'd room  Sad

Maybe I could manage it remotely and underclock if it gets too hot?

Bear in mind that the mod REDUCES the airflow over the sensors, so temp readings are not that accurate (even without the mod).
What only you can tell for your ambient is how well the machine is running .... e.g are you getting more HW errors with the mod, are you getting higher diffs / faster diff setting by the pool? If you are getting less errors (assuming you've OC'ed), then that is a good sign the mod is doing well.

There, ma friend, lies the root to the rise in temps ..... try using simple card-board over the top and bottom (while you sort out the 3D printing) and you will see a drop in temps.
Should the cardboard on top sit just above the heatsink and not extend across to the sides? Or should I try to sit it on top of the PCB board, extending to the side panels?

Thanks

It's possibly worth noting I don't have top or bottom plates due to printing difficulties.

Printed off the 2 ducts and have them mounted with 2x Ultra Kaze's. Here's a comparison:

Old setup
Kaze Pull + Stock push + no ducts = ~53°

New setup
Kaze Pull + Kaze push + 2 ducts = 63° / 59° (there's a few degrees difference between both boards strangely..)

Are the above temps expected with my new setup? I was expecting a bit cooler, especially in this air conditioned environment.

It's possibly worth noting I don't have top or bottom plates due to printing difficulties.

Edit: temps have risen to 65° / 61° now  Sad

Seems about right with Kaze. Try it with the stock fan and undervolt it a bit to reduce noise & power usage. I went back to using just the undervolted stock fan now and it uses less power, creates less noise, and cools better than 2xKaze. I go based off the temperature sensor though - the 2 fan layout would cool more evenly and might be cooling better than the sensor is reporting.

I haven't installed my set yet, but good to know that Denver Bitcoin is so close to home.

I'll have to stop by one of their "meetups" someday.

anyone know where to get those heatsinks from? the ones in the first picture that it came with?

you can get ones like them from ebay or amazon..
although i dont think they are needed or even help much.

I sent a pm to get on the list if you guys are still printing these!!

Sent ya a PM...

Im pretty much caught up with everyone if people still want these printed for cheap let me know!

i got my set today from jstefanop.
they look just like the OPs.. mine came black.
i was only able so far to put the top and bottom plates on as i coudlnt find the right size screws for the fans...

You can use original screws that came with the miner, just get them though your fan as described in the first post. If you can't get them through the fan, you need screws that are 40mm + fan depth/thickness. M4 thread.

i dont think the fan screws are long enough?

i guess i can take it apart and check.. but i figured they were too short to go through the fan and the fan shroud.
.


If you got the screw through this way, it will be long enough:



This is not intended to be used with the stock fan, but it will work.
The temperature readout will be more accurate, thus a bit higher than before.

i got the front fan shroud on..
the temps went up a tad in the ui, but i think its because the fan shroud doesnt let as much air in sides..
one thing to note, the stock fan cord is not long enough to plug into the board with the fan shroud.. it was about 5mm too short.
i had my fan on a molex adapted so its ok.


the fan still appears to be quieter with this then with the top and bottom open.

they fit perfectly.. the temp being reported by the miner didnt really change.. but i didnt expect it to. as i took out the blue wire for my fan so it runs at full speed and added a 2nd fan.. my s5 runs in the 48/50c range.
but, there was an unexpected change.. the s5 fans got quieter (you hear the air more then the whine now).. im thinking its because they have to try harder to push the air? or maybe its just the fact that not much air escapes the side and none now escapes the top?

i like it.. it should have been manufactured with them.

thanks again jstefanop

put this model in on shapeways.com just got half of the bottom plate tis $47 lol

Im doing the whole set for 35 + shipping. Just pays for material costs and few dollars for my time. Send me a PM if you want to be added to the list. Printer is printing full time now but I have about a weeks worth of parts to print and ship currently (takes about 12 hours to make a whole set).

Here are both of my miners with the main boards screwed onto the top plates. The screws screw in into the plastic perfectly. I prefer having my ethernet cable running out of the miner at the top. It's also easier to see status lights and ethernet activity. It is just as easy to have it all on the bottom.

I was also playing around with a vertical design, but was placing it the other way with the fan being on the opposite side (as it comes stock).

What's the benefit of having the side with the ethernet jack face upwards with the fan on the bottom vs. the stock layout of the fan being on the side with the ethernet jack? I found the temperatures were cooler running it vertically with Ethernet side down.

With the stock miner, without the top and bottom plates closing it off, it is better to have the control board next to the push fan as it is preventing some volume of air from escaping the heatsink immediately, thus lowering the temperatures a little bit.

With the miner closed with plastic top and bottom plates it doesn't matter which side the control board is on. The only benefit is easily seeing if miner and internet are working properly, just by standing next to the miner. No need to crouch and look under.



Where do you get the screws for this?

Hardware store?

First I ordered some from eBay, from Chinese suppliers, but then I found a screw store not far from me and got the rest there.

I would definitely not recommend printing the parts with industry-grade professional 3D printers. They will come out expensive and I have not tested their durability.

A RepRap PLA or ABS printer can do a perfect job with these. I will start printing one set of parts for the AntMiner to see how much time it will take me and put it on eBay later. Just got a delivery of 2kg black PLA filament.
