I am running them laterally mid in Sahara Grin

But the elc cost are low Wink

For my new S5 I am planning watercooling and using some big ass car radiator. But for the S4 I need to find a good solution as I have already 5x S4 getting to mush dust.

I am not always around so I cant use filters and replace them every week or so..... I need a solution that dont need a remote hand for as long as possible.

Well that would explain the dust

.

The problem I see is I don't see water cooling as a option. Just no one has put money into it that I know of. So that would mean custom parts so high to do it.

The amount of dust you have I don't think will matter what kind of fan no matter how good it will die off from it eventually. (My opinion I could be wrong. Even if fans don't die it will have dust build up on exhaust).

I think you will have to go with a filtered option. It's not perfect but you could do a filter for main room it's in (and clean it really good to get dust out before). Then maybe build a enclosure for your S4 with extra filters. Hopefully by using multiple it will allow you be remote for longer and not kill fans or worse machines.

wel I was going for a car radiator as I was think if it can handel a car, it should be fine for miners. because I have never clean up my car radiator.

my best geus is that if a fan use sealed bearing it should last much longer.... I think I should just get some of those delta fan and we will see if they can last more than 3 weeks.

Ah, that explains the low quality pic.

Dust will still be an issue with water cooling, you'll just clog up your radiator. If you can't prevent the dust from entering the building or the miner with filters, your only solution is cleaning them out regularly.

what would be a good fan replacment? I dont really care about noice Grin

I assume if you can get the chips cooler they will hash more and also more stable right?

Not really, no. Lower temp might contribute to having less "x" chips, but probably not unless you're close to 80c. If you don't care about noise, get some high power Delta fans.

Noice isnt my problem, dust it is! 3 fans are death after 3 weeks only, see pic. I am looking for some fan that can handle dust. sealed bearing maybe? Higher rpm?

Damn, that's a lot of dust. If I were you I'd open it up and blow it out with compressed air (from a compressor, not a can) every month.

Delta fans are pretty much the best quality fans out there, if anything will deal with the dust it will be them.

How old is that camera? LOL

nokati what type of environment are you running in? That is not normal dust build up in 3 weeks on top of miner.

I personally have never had a dust problem like this. Yes every few month's maybe spray them out. But it appears you must be running in harsh conditions.

Your fans won't go above 3K if your temps aren't high enough. If you're getting 1.5TH, you likely have a dead hashboard. Look to see if one of the board's red LED is off.

I haven't mined on nicehash but I believe it's one of those altcoin hopping proxy pool, isn't it? Altcoin blocks are much easier to find than btc blocks. Too bad those weren't all btc blocks. I'm guessing you've found quite a bit of practically worthless altcoin blocks. Wink

ok that makes more sense

So one of my Fans died,

I bought a Delta TFC1212DE-PWM to replace it:
12v
5500 rpm
3.9A

I connected the 4 cables correctly for the PWM,
the S4 starts correctly,
when it starts mining, that fan starts slow down, from 3000~ RPM, gradually to 1800~RPM, then to 600~RPM and then if turn it off after a few minutes (like 10min).
What is wrong? tried checking the connections and are correct.

So i disconnected the 2 PWM cable connections, and now i have it running like that, at max i think 5500rpm.

Anyone have an idea or clue on why the S4 PWM eventually disables the FAN?

Maybe im doing something incorrect? or the fan is not compatible with pwm of the s4?
Thank you guys.

Like other S4 owners, one of my PSUs blew shortly after the 90 day warranty. Bitmain's response? "find one from your local market".

It's astounding that Bitmain will only give a 90 day warranty on their PSU.

I was pretty sure I wouldn't be buying anymore Bitmain hardware. This sealed the decision.

M

Sorry to hear that. The warranty should definitely be extended on the PSU considering it's horrible MTBF.

That's what I said to them. Just about every namebrand PSU manufacturer offers a minimum of a 3 year warranty. If Bitmain is only offering 90 days, that essentially means they are using junk PSUs in their unit.

BUYER BEWARE.

M

I agree. Only a 90 day warranty on PSUs is very bad. Almost all standalone 80+ Gold ATX PSUs I am buying with 5 or more years warranty.
But they are not alone, for example also I had not good experiences with PSUs from Gridseed (their A1 miner).

Definitely leads one to believe they have no faith in the quality of their PSU.
