Data Center Mining Garage and Man Mining Cave ( PART 2 !!!!!!!!)

Does anyone have an experience with 1 fan variants of cards for mining? (XFX, PowerColor). Do they run a lot hotter than others because of the 1 fan, or is it okay? Also the MSI Armor RX470's, how's their cooling? I've heard that they run hot because they only have 2 heat pipes, but I don't have one to confirm. I have an RX480 Armor with 3 heat pipes and it runs fine.

No Problems here with Powercolor 470 Red Dragon (single large fan) but of course undervolted so one card draws around 100W for ETH from outlet (ZEC mining needs 14% less). The open air rig has a quite large distance (ca. 2 inches) of cards - maybe this helps.

I have single fan XFX rx 470. No issues with it, very silent compared to reference cards. But I'm worried if the fan dies, the card will overheat. If one fan in a dual fan gpu die, it won't overheat as bad.

I'm very impressive, i have a question:
What gpu do you use you said 480 i think it is msi witch version and what is it your hash rate ? 24 / 30 mhs ?
Cause i wanna also build something but i don't have idea how to avoid shit Micron memory controller.

Thanks for any info.

470 Armor OC 4G have 2 heatpipes
480 Armor OC 4G have 3 heatpipes

@ Navy Dude - If I get to do it all over again.  I wouldn't bother with a small shed.  I would build a large structure where I don't need GFI.  GFI is simply not good with PDUs as the more devices you have connected, the more likely 1 device will have issue causing everything to trip.  The constant breaker tripping even during drought weeks tells me it's not humidity.  I've replaced breakers, and the issue is very random and it can happen at night or day time.  This can occur on any of my 4 GFI 30AMP breakers.  This is getting annoying and costly.  Going non GFI 120V is not an option for me as that would consume double the amperage and going non GFI for 240V would be asking for trouble and potential death.  It's not worth the risk.  Cooling wise it's working well but the best you can get with air cooling is same as ambient.   If the outside ambient is 105-110F, I would recommend  turning off for the peak hours where it reaches those temp.  You would lose only a few hours of revenue but will avoid costly damages.  The rest of the non peak hot hrs should always be well below 100F making it safer to run.

Thanks for the heads up. I have to find a way to get them going safely. I lost alot of GPUs last summer and that is costly. What would be the difference in a big shed and small shed and using and not GFCI breakers? I cant see it would make a difference other than if a fire started. But either way its gonna burn!! Big or small. I have all my rigs on 240v non GFCI. Running Two rigs on double pole 20 amp breakers. They are in my house currently but I do want them out soon as possible...Just in case of fire. Plus heat is very unmanageable!

that's what I thought/said, I was wondering if anyone knows how big of a difference on cooling it makes.

okay thanks guys, that's what I wanted to know, I have my cards undervolted as well, just never tried a 1 fan variant. Do you dual mine with the 1 fan variants?

Was considering something like this. Maybe 2 or so...They are expensive but would move some serious air. I think if i can get the air flow great enough 100-105f wouldnt be an issue. I like to keep the temps of my GPUs under 80c and I guess the only way to know is by trying it.

No dual mining here, going for the least power draw due to high electricity costs

@navydude GFCI breakers/receptacles are recommended in wet areas, and pop to protect the user from being shocked. That's why they are recommended on the exterior, garage (except for freezer/refrigerator because they can be temperamental and you come home to a defrosted mess), bathroom and kitchen.

There is also AFCI, which depending on how old your home is (in the us I believe after 2005 they started in bedrooms, and now on panel upgrades and new builds are required on other circuits). Arc fault circuit interrupters pop if an arc is sensed, which is temperamental as well.

In a shed type situation that isn't insulated or conditioned GFCI is the smart way to do it.

zec + nvidia = lowest power hash per watt.  simply crush anything AMD has for mining zec.

I still have mostly all AMD  but I see a big switch to nvidia on my part.

i dual mine with my powercolor single fan red devil 470. temps are in line with my msi dual fan 470. but the single fan card runs at higher rpm so is a bit noisier.

[miner417]

Thanks for the replies everyone.

I just got in my order from Hawkfish today, and my TB250, so I was making my first real rig. Went to power it up for the first time, heard a pop, a burning smell. PSU was DoA, 1200W Platinum EVGA

Now have to wait until Monday amazon says to get my replacement. Hope it didn't hurt any parts I had plugged into it...

@Navydude - If you have a larger structure, it will most likely be more secure and protected against moisture or potential for leaks, etc.  For small shed, it's impossible to build something that strong where it can survive strong storms, etc.  So GFI is a must in those situation vs potentially doing away without GFI.  Using GFI is not good for mining or PDU as the more devices you have on the strip, the higher chance something will trip or cause it to not able to reset.  Not using GFI when doing 240V is asking for a death sentence as moisture and wet area could be very dangerous if you have a power leakage somewhere.  240V will kill you unlike the 120V shock that you may be able to survive if you have room to get away.  Going 120V is another option but that would waste double the amperage.

Regarding fan CFM - IT really depends on your shed size.  REmember higher CFM = more noise usually.  However you can get multiple smaller fans and combine they can move similar CFM and not be too noisy.  This is why I'm using my ORIONs.

@miner147 - Single Fan GPUs are fine for 470 as they don't run as hotas 480s anyways.  For 480s it will get warmer or louder via faster RPM as the single fan have to work harder but for 470, they run super cool.  Regarding the PSU capacitor blowing up.  Usually it doesn't hurt other GPUs or MB but sometime it does.  I have 2 go out on me.  The good thing with EVGA or AMAZON is the return / RMA is super fast.  Very surprise to hear on the Platinum 1200 which uses Japanese Capacitors.

@ dddrgonzooo - Correct, just more ways to be tripped happy.  I run only 2 or 3 rigs per PDU in the shed now, talk about huge waste! 

@ phillipma1957 - Until there is better Mining software for NVIDIA, AMD is still KING for the coins we care about for now which is ETH and ZEC.  More importantly if you're dual mining.  Also NVIDIA is very flakey in 6 and 7 GPU setups due to driver and mining software compatibilities.  This is why I'm still 100% AMD.

ZEC is good with NVIDIA; can't say for the rest of coins though ~ ETH is poor for example.

Eg. EWBF and Excavator miners drives high ZEC hash (even higher than ZEC on Fury X at very low watts).

Many good cgminer forks for other familiar and unfamiliar algos like DCR, LBRY, Lyra2, X11Gost etc.

Pros: ZEC killer (and only ZEC though, I wonder what clicks in ZEC and NVIDIA architecture), impressive wattage - better than AMD

Cons: Bloody expensive...

Started building my first ZEC rig on twin 1080ti, hopefully this will be an equivalent of a 7-8 rig AMD ZEC rig, at half the watts. Patiently waiting for Phil's weekend review.

You can consider some RCDs, basically the EU version of GFCIs. They are less sensitive since they are designed to protect whole buildings or large portions of one rather than individual circuits.

[miner417]

@Yun9999 I was shocked it happened as well. I've trusted EVGA products for years, and knowing that the 1200W plat is literally the best possible, having it die on me on very first power on was pretty shocking. Could it be that I had it plugged into a surge protector with a monitor and box fan as well? I really don't think so since I did hear the pop in the PSU and the smell, plus the fan/monitor stayed on and constant, just trying to figure out how it would have passed EVGA's inspections on their devices and still pop instantly on me. And thanks for the heads up on the 1 fan variants, I'm running just an open air build on a homemade wooden setup, so I'm guessing it'll be fine. Ambient temps are always around 70, maybe 80 highest in the summer.

[Mikkiun]

You are a smart guy. I 'm really interesting with your mini mining garage. I will try to get a mini room like yours .
Good luck , guy.

I have a nvidea mining Rig, it consists of 1070, 1060, 980, 2 x 970. Only the 1070 is new, rest all i picked second hand. This rig runs on windows / nicehash and mines bw Zec, Lyra and Pascal. Its very stable, much cooler and I am sure I can sell the cards very easily when ever I want to. So if not for ETH, its Nvidea for me too !

Also nvidea supports much more algos(nicehash) than AMD, so I think its going to be much more future proof then AMD.

2 cards now  one  1080 ti one 1080


watts for entire rig = 373
h for zec                = 1168


pretty much  kills anything from amd in the world of zec

my advice is build 3 six card amds
for every 1 two card 1080ti

two card results

why not get two 1070s with low power limit they will do around 930 zec for around 300 watts the 1080ti should be doing like 1k for it to be worth it
