Sixth alt coin thread I forgot to mod last thread.

Dude, how much power does that thing actually draw? I'm all for good airflow but this looks like it'll suck the power off of your rigs!

This contraption has its own 20A circuit.

It shares the circuit with 3 industrial fan blowing out towards the windows.

Building rules prohibits me from modifying the window and install barn fans...

It eats 520watts and can suck 65 metre square of air volume per minute.

Its currently turned off and will in good use when its needed on hot days.

The warehouse has 63Amps/3-Phase 220-240v power so my electrician says I can play with 3 x 63amp = 189amps - less 10-20% for safety buffer.

So 150amps divide by 5amps (6xGPU-rig) or about 8amps for the 12-13xGPU rigs = 30 rigs (6xGPU-rigs) or 18 x 12-13xGPU-rigs.

runs hot were you live 30c/86f  is a good day correct?

[kjs]

guys, trezor vs ledger nano s, which one do you choose?

Ledger FTW.

[philipma1957]

My exhuast fans arrive thursday gott find a roofer tomorrow, btw how do you guys get imgur photos to display as pictures not links ?

Use the direct link

you are too new to post a photo.

If you give the direct link I can fix it.

runs hot were you live 30c/86f  is a good day correct?

Yup. On a nice day 33c max, 29/30c at night. During hot days, 36-38c

There was once -- the whole week was too hot - 38-40c - some El-Nino event - 5mins inside the warehouse and I almost fainted because of the high temps, noise from fans running 100% and EMPs from the rigs, that was when I got that 2 x blower last year.

I also slowly discovered what components of the rigs were not up to the standard of 24x7 mining.... the obvious culprits were the cheap network cables going bad, Gen 1 USB risers and poorly built 4-pin molex. The EVGA PSUs worked like a champ even on high temp conditions.

Those times were stressful because the farm was crunching ETH all day - high electricity consumption, too much heat too. Power tripping became frequent - probably due to overheating PSUs. Those capacitors on the USB risers popping like popcorns with crackwhip sound occurs occasionally too. Probably due to heat and sub-standard build from Gen 1 USB risers from my R9-390 rigs circa late 2015-early 2016.

During this life after ETH, we have a combination of ZEC and XMR mining so the temps are not too bad - but when its hits 36-37c (near 100f) on a hot day - I turn on the blower to reduce temps by at least 2c.

The H110+ although nice because it supports 13 slots and runs out of the box without any major settings from BIOS... HOWEVER  the cons are - slots very close to each other so you need to pack them and be careful not to get them into contact with each other. The board also need 2 x 4-pin molex or SATA power onto the board.

The TB250 12 slots however is better designed, dont need the powered molex onboard. BIOS settings a bit tricky but once set up - runs stable.

I have 6 of the TB250 running RX470s quite nicely - fully populated. I have 3 x of the H110 too - running stable also with RX470s.

I didnt get the 19 slotter because this kind of rig poses many different challenges like PSU, power consumption, circuit allocation and cage design.

Anyways, I think focusing on the riserless mobos is better strategy moving forward. Save money on unreliable risers, better heat control and lessen OS compatibility issues.

How do you distribute the necessary power to the h110 board + 12 risers? esp with 2x molex going into the board

"It eats 520watts"

God damn, that is one crazy fan.  Must be noisy...but efficient.  For the other subject, I ordered a ledger nano s but shipping is now in october   supposed to be september...ordered it this summer.  Hopefully it'll get here before xmas.

I am out of town but cant wait to get back home to work on those boards.

I had limited testing on the board but looks like is working - but MingMining found some kinks on 1st and 2nd GPU slots -- I think there is a special setting on the BIOS to make it work.

I sent a unit to Philip too - I hope it reaches him soon. He can do a more detailed review.

Actually I had the medium sized blower, 250watts but overall temps reduction is only 1c, so returned it and got the bigger one instead.

I have 2 x Trezors for daily use - I like them very much.
There was a buy 3 bundle so I got that. 2 for me and 1 for the wife.
I have a Nano S but seldom use it - its under lock and key.
I keep my small stash of BTC and LTC in the Nano for long term.

when its too hot i work wearing my underwear only....nobody is around 

you get out as soon as possible, get the job done quickly like a true ninja.hhiiiiya!

all this time reading you guys, i really thought you were canadian.. judging by those temps i guess i was wrong

I love the sound of eliminating risers if possible. Just the time saved troubleshooting the rig if it's acting up would be pretty valuable, even without the additional cost savings. I hope that somebody makes one with ample enough spacing to run a full 6-8 higher wattage GPUs, such as GTX 1080 Ti, Rx Vega etc.

i don't get what citronick is saying about "better heat control" but risers are important to make space between hot gpus, the closer they are together the hotter they get..

quality risers are good, most of my risers from late 2013 are still going strong. and add to that my 775 motherboards circa 2006-2007 that are paired with these risers are still working...

look at that very long motherboard and look at the capacitors in between pcie slots, if only one of them gets cooked you're gonna get some headaches.

Finally! You got your 5th subscriber, Phil! Great video quality by the way.

Speaking of new vs slightly used Avalons... I usually can tell how well (or for how long) some piece of electronics was used by smelling the exhaust air. If it has a fan, the electronics aroma dissipates in a few weeks/months of 24/7 usage, especially when it's getting hot. It's like the new car smell. Plastics, adhesives, soldering flux and all the other good stuff.

For example, I can tell that roughly half of the 2400W Deltas I received from Parallel were very well used since they didn't give off any flavors whatsoever. A few were brand new and a couple appeared only slightly used. Two 750W HP PSUs from them were brand new. After sitting for a month at 50% load in my garage, the new ones don't smell anymore...

quality risers are good, most of my risers from late 2013 are still going strong.

The non-powered ribbon style risers do work nicely especially if they are well made. However, with newer GPUs requiring more power, the newer risers that have voltage control, better capacitors and 6-pin power (v6c/v7c?) is the gold standard for riser based rigs. Avoid the molex powered risers or any of the v1 to v5 risers.

Better heat control can be achieved more efficiently with riser less mobo builds, using in conjunction with powerful "Scythe" fans placed back and/or front of the cards depending on reference/blower GPU or otherwise.  If done properly, you could get 1080tis with paper thin spacing at beast mode and still attain acceptable temps.

Currently, I use a "vertical GPUs on S hook design" for the RX ETH farm and also using zip-ties for the newer builds on TB250s and H110s....

I will try and get some pictures to show my experiments in the warehouse..... but my group members is kind off anal about showing pictures of the farm.... but will take some discreet shots.
