@KeezAZA: too complicated because of extra psu for peltier&fan, extra heat that you need to get rid off); not worth if you pay for electricity! It should be just an idea that you leave behind in the next second Wink

@at the rest of the guys thinking to submerge: too complicated, check the price of the submerging liquid and chill out! Grin

I will call my friend he is a cooling engineer he knows a lot about air pressure and airflow and all that stuff. and see what he says.

Or just buy a fish tank and submerge it in pure mineral oil then no fans are needed.

take a look at this way to expensive though for what these miners make.

Cool idea. I am planning covering up the top and bottom sections with perspex and adding a peltier cooler device to the front of the S5 maybe infront of the stock fan or after. Will have to do some tests.
Based on the previous posts. -10C intake air gives a nice ~30C running temp.

Shall See when the unit arrives. Roll Eyes

Is it possible to have a real fish/animal tank? Any funky creatures that could survive in that environment? I guess you could just experiment but it might wreak havoc on the filters. That would be ultimate coolness though if you could have an actual animal tank. show me pictures of that

Bitcoin mining farms do it. Its called submersion cooling checkout this video big mining farms already do it.

I wonder just an air pump under the miner in the tank would make air bubbles which will catch the heat in the bubbles and bring it to the surface but I think this will not cool the mineral oil enough.

here is another very interesting one which I like.

and here is even another link right on our forum.

Thanks for posting this, a video on the site answered a big question I had which was would a fan work submerged in mineral oil and the answer is yes (but much slower), wonder if a stronger motor would fair better (ie., 1 amp to 3.25 amp). With the video, it shows that miners submerged, may just be the answer for those willing to pay for the quiet at home. Now for the ultimate home project, wait for the C2 to be released and have 2 running in mineral oil with one radiator for the mineral oil and one for the coolant.

Seems like a simple solution exists to me. Switch from "fan mode" to "propeller mode", admittedly I know nothing of this magic fluid. It is interesting!

I believe my Antminer S5 is Dead on Arrival, I attached 4 PCI connectors and turned the power supply on and the machine does not power on. None of the black buttons are working either.

I'm using the 750 W Rosewill ATX PSU.

Anyone have any ideas?

Did you put a paper clip on your power supply ?

Are you using the right paper clip on your power supply?

Test supply, if the fan spins etc... and no miner, find the reset button and hold that and pray.

Wonder if someone has done something really crazy like that, with the coolant radiator also submerged in mineral oil in a separate tank (with the oil going through a radiator on a separate channel)?

No, unfortunately I forgot to look. The other problem is that on the Bitmain website there is no version number or date so I didn't know if it was newer or not. So theoretically I installed the same firmware, but it is acting different.

Version numbers are in the title, ie 20141024 is 24th Oct 2014.

Oh, silly me. I guess I missed that part of the Antminer manual.

I noticed when you lift the s5 up to were the bottom is open the temps skyrocket at well as the rpm and noise on the S5 stock fan.

maybe I should get Plexiglass and make a bottom for it or seal the bottom off so no air leaks out.

what do you guys think ?

Does anyone use 2fan for cooling?

Planning to put on two 1500rpm fans to keep quite this thing.

dont waste of money

two of these are the best.

http://www.ebay.com/itm/Delta-AFB1212SHE-Computer-Case-Power-Fan-120X120mm-Lot-of-2-/191472588964?pt=US_Computer_Case_Fans&hash=item2c94a7d8a4

my tests with them

https://bitcointalksearch.org/topic/m.10158497

you can go low with 5.5 volts to the fans --------------freq 300 990 gh very quiet

or high with 9.2 volts to the fans-------------------------freq 393 1292 gh 10 db less then the stock fan.

Thanks I would have gotten those the only reason I did not is because I want the 4-wire fan not three I want to use the fan header on Controller.

Well now I am stuck with two Silverstone's which will be here Monday 1/19/2015 !!!

ahh the silverstones don't cool as well as the delta's. but they are pretty good.

How much quitter are the Silverstone's then the delta's ?

I was having reliability problems with my Batch 4 S5 that just arrived this week, so someone suggested I update the firmware with the latest (Jan 7) release on the website. Ever since I updated with that firmware I have had troubles. At first I had problems with one blade not coming up, then I did get it working about only at about 800Gh (default settings), and now almost 3 hours later I am down to 680Gh.

Does anyone have the original firmware available for download?

Did you check the "File System Version" on the System/Overview page before updating? Mine arrived Thursday (shipped Monday) and already had the Jan 7 file system installed (Wed Jan 7 14:05:02 CST 2015)!

No, unfortunately I forgot to look. The other problem is that on the Bitmain website there is no version number or date so I didn't know if it was newer or not. So theoretically I installed the same firmware, but it is acting different.
