That can have quite a bit of effect on card temps.

 Also, how much SPACE do you have between the cards - if it is less than 1 inch it isn't NEARLY enough for proper cooling, really need 2-3 inches for good cooling.

 You still haven't mentioned what you have your fans SET at - if you are using the "standard factory" settings, that IS your issue and you need to bump your fan speeds up.

 That varies.
 Many are 151 watts (not 150), like the FE and Gigabyte "ITX" and MSI "Aero mini" and EVGA SC (specific examples I have), some are 180 like the Gigabtye Windforce (both 2 AND 3 fan models), at least one MSI model is 240.

 "Optimal settings" also vary as the DEFAULT clock on cards varies widely, the default MEMORY clock varies some, and various brands of memory tend to have differing ability to overclock.
 "Optimal settings" should be specified as being for a specific card model - and there is enough variation even THERE that sometimes the optimal settings for ONE specific card will be "can't handle this, crashing all the time" on another card of the SAME model.


 "Simple Mining" is a LINUX based distribution, Linux controls for TDP for NVidia are in watts not a percentage - which IMO is a LOT more sensible.

The latency is UNAVOIDABLE due to the distance from geosynch where the sat is at to ground.

 It has nothing to do with the hardware, it has to do with the speed of light taking time to get the signal from you TO the sat, back to ground, to the server, back FROM the server, back TO the sat, back to you - even if you were on the equator directly under the sat the "speed of light latency" would be a hair less than 500 ms JUST for signal transit time, it gets longer as you move away from "directly under the sat" because the distance gets longer - THEN you get to add "normal Internet Lag" on top of that.

 Your GPU may not support a recent-enough CUDA compute version to work with EWBF.

 

 You appear to have some sort of cooling issues, or the room that miner is in gets VERY hot - or you have the fan settings WAY too low.

 65C is 149 F - which is too high to be safe for home water heating, definite scalding risk.
 Sure they didn't have it at 55C? 131F would be a little on the high side but in the "normal" range for hot water temperature the outlet of a water heater.

 Also, what did he do when he DIDN'T need the hot water running?
 Or was it setup as a "recirculation" system through the GPUs and the solar heating array?

 Newegg has some of the 570 cards down to as low as $229 (though I think that one was a refurb) and quite a few at $249 today.

 STILL not down to pre-shortage levels but getting closer.

 EWBF works with any NVidia 10xx series card and I believe also works with all the 9xx series cards and the 750 ti (Pascal and Maxwell generations).

 CUDA has been supported by ALL Nvidia cards (in some form) for quite a few years now.

Odd thing - the Nvidia LINUX driver most recent version that supports the GTX 1070 ti is 384.something.

 Gotta wonder if they were DELIBERATELY aiming this card at least in part at miners since the Windows version took so much longer to get support into it (388.13 is the FIRST for Windows with 1070 ti support).

 ETH is very memory intensive - you DON'T want the same overclocks on ETH as on ZEC on most cards for best efficiency and hashrate.

 Also, part of your heat issue is that you're pushing the cards to WELL over their design TDP specification - on the other hand 70-75C isn't an issue for modern video cards and most of them are fairly comfortable at 80C (though that likely DOES reduce their lifespan a little).

 Unlikely for the near future, as Ryzen CPUs don't support very many PCI-E lanes and the CPUs themselves are still pretty expen$ive.

 70% TDP on most GTX 1070 models is either 106 watts (151 "default" watt TDP cards like the Gigabyte ITX, MSI Aero, EVGA SC, Zotac Mini) or 136 watts (180 watt "default" TDP cards like the Gigabyte Windforce 3-fan).

 Why are you insisting on mining ETH on a GTX 1070?

 They do a LOT better (and soak a bit less power usally) mining other stuff.

 Watch ETH show up NOT as a Top 5 option for that card.

 And if you can't find those specifically, the EVGA G2 used that SAME platform - and showed up at up to 1600 watt rating.

Even the last couple years I was in Iowa, which has actual COLD winters (PNW has very mild winters), I had to keep at least 2 windows open partway with fans running in the intake window to avoid OVERHEATING my home.

10 cent per watt electric is VERY MARGINAL at best for mining Bitcoin.
You want to get a LOT lower than that if you want to be profitable for the long term - definitely 5 or less, and optimally 3 or less.

Best way to monitor your rigs would be to set up a VPN between your warehouse and your home.

 I tried that on my S5 units. ONCE.

 The temp of the miner went up a LOT due to the flow restriction the filters put on the fans.

 450 is reasonable for a GTX 1070 at a fairly high TDP.
 Not sure on the 570, my 470 models that's about where they end up at so should be about right.

 G2 cables exchange across all models *EXCEPT* the G2L stuff.

 Not sure otherwise, as all of my EVGA supplies are G2 models.
