Help with my s5 Temps

[chaoman]

Hello thanks for reading the thread.

I recently got a s5. It was super loud so I replaced the fan with a noctua 3000 rpm fan. However the temps were getting too hot so I reduced the frequency to 300. I also put a hardcover book against the bottom of the s5 and placed it vertically. Any ideas if the book helps or not? I saw other users put covers over the bottom so thats where I got the idea. The main issue is that I live in a desert so the ambient temperature is quite high. Temps are at 69 and 70 at the moment according to the antminer UI. I am going to purchase a normal indoor fan and put it under the s5, hope that helps.

Any ideas?

edit:

When I set the ant miner on a flat surface one board drops to 62 degrees and the other jumps to 71, what is the cause of the 10 degree difference between the boards? anybody else have this happen too?

you need two of those fans not one as push pull by that I mean one on the front that is pushing air in and one on the back pulling air out . it sounds like your using just one, it won't work like that, trust me . i tried it .

or that one very loud stock fan . then with two in that way your temps should drop below 60 C and sty there at 350 . unless you house has no air or way of moving that hot air or cooling it off .

what were your temps with the stock fan ?  forgot to ask .

[notlist3d]

It sounds like your ambient temp is to much for that RPM of fan.   The S5 just is not a quiet miner.   You can go down even more on freq and it will heat up less.

I would put original fan back on personally and it's loud and warm but it works.

I couldnt stand the stock fan long enough to see how it runs. I am mining in my room so the loudness is an issue. I am going to get heat sinks and put them on the chips. I suppose I will get another fan also.

be care full with the heat sinks per chip i did that and ruin a S5, I didn't even bro getting it replaced, i knew i messed it up. by that I mean make sure those heat Sink just fit on the chip and not over lap or touch any thing. but i would try a fan first it's a safer way to find out . and one other way but try the fan first , re paste the boards. o yea water cool it if you want to go that route .

how did you mess up your s5 with heat sinks? I am new to changing hardware around and I don't want to do the same thing. I thought you just simply put the heat sinks on top of the chips? How can this break the s5?

You already have two major heat sinks on the chips.

If you do not know what to do, then it is better not to do.

I live with my miners too. What I usually do is to reduce the fan to lowest which runs 2400 -2280 rpm when I sleep. I increase them when Im not home or simply when I have headphones on. 2 noctua would sound as much as a stock fun running at 2400 rpm. Im still trying other options, Ill try to put a box fan soon. Gonna try a new setup soon, I'll put a silent but avarage fan to pull while using stock fan at %30.

Btw, some of my miners run at 2400 rpm while I set them to %30 and some run at 2280. Does anyone happen to know why.

1) one set of chips could be better then the other
2) the heat sink may be pasted better
3) the firmware may be different
4) there are different pcb boards you could have two different boards.
5) one psu gives better power then the other thus affecting the temps thus causing the fan to spin faster
6) something else  that I did not think of.

as tup said it's best to be safe they cost enough all ready , but anything that touches any thing that it's not suppose to will short it out .  if that makes sense, so  to big of a  heat sink that may over lap on the board might hit some thing turning it on will short it out  or if you want to take them off and they have good solid tape holding them on might not come of so easy.I know that's how i did it, i had the right heat sinks coming but couldn't wait,which became my lose i put on the wrong size heat sinks etc the rest we know.

It can happen.So i wouldn't do it unless you know for sure just what to do as tup  said and a lot others  will tell you

.which i do now at a lose . and yea all you do is put them on the chips but don't over lap and find out the right way of taking them off ..

One way to damage is by the heatsinks touching other components and possibly causing a short circuit.

MAJOR POINT: Do NOT just use self-stick thermal pads/tape to attach the heatsinks!!!! Always use a thermal epoxy to make sure they stay where placed. Temperature and gravity WILL make them start sliding off which could/will cause short circuits. Been there, done that with S1's. Within 2 months many sinks had fallen off....

Plus I've also found that moving them around or one place form another place can do it the list can on as to  why and  there might not be a thing wrong either .

I have also replaced the fan and using 2x Scythe Ultra Kaze 3000 now (0.6 amps @ 12V = 7.2 W, 45.9 dB). The specs (CFM and pressure) are slightly better compared to an Noctua NF-F12 industrialPPC-3000 PWM (0.3 amps @ 12V = 3.6W, 43.5 dB). I pimped the top and bottom of my S5 a little to have a better airflow (well I wrapped it so its looking like a coffeebox and its more like a tube now). I've also added a Fanmate to control the fanspeed.

So far my temps are good (always below 60°C with a little downclocking). I try not to hit 55°C and Chain 1 is always a bit hotter (4-8°C). I also bought an Delta 1212EHE-F00, which looks quite like the original (59dB, 190CFM, 2.0A) - I never used it, its a spare part.

Edit: Remember dB is a log, so +10 dB doubles the noise.

you should put the stock fan back on, that noctua fan isnt going to cut it IMO.. unless you have two

[flikflak]

Yep, go for 2 of them and try to stay below 60°C. Afaik Bitmain recommended it so.

Whats your dB from a meter away with 2x Scythe Ultra Kaze?

my best results were 2 deltas I could lower sound from 72db to 53db  and I ran the deltas at 9 volts.    plus i completely avoided  the problem of it the net goes down the  s-5's can burn.

I used this as a fan controller

runs up to 4 deltas at 9 volts

 I used  the same psu that powered the s-5's  to power this fan controller

Sorry, I can't measure that, but I think those 45.9 dB are 1 meter away. So add a little bit more (turbulent air trough the heatsink fins and the fan mesh). But noise levels are much better now.

Hmm, Ill target kaze for my future experiment than.

FYI, if you have an android phone (or iphone) there are apps that measures dB.

What is the safe range for temps? I am using two SP120's and getting into the 70's while testing it, decided to shut down and do some research.

70's are too high.  many get away with low 60's
