GPU Mining in Texas Heat - 112 degrees - No AC!

I just turn off my rigs on hot days. Not worth destroy equipment to make a couple of bucks a day or break even with electric cost in this mining environment.

What kind of temps do you see on a hot day? Outside and the Card temps

In a house, I think as long as you're able to evacuate the heat without pulling too much hot air back into the house, they'll be safe.  Mining with ASICs in a warehouse (with 107F outside temp) still allows for "cool" air to be pulled through, while dumping the hot air outside.  GPUs might need a little help, though.  A makeup air system works best, in this kind of situation.  107F cooled down to 85F or so, is all you need. 

Amazing burn money.

You could try out DIY watercooling your rigs, I'm pretty sure that will get temps down even in hot days. I personally watercooled my 5 card rig under 50USD and the temps really got amazing (used r9 290 cards, so 65C is pretty good result with them).

Rig was inside, radiators were outside on a balcony

true that
with profitability like this
its better to switch off if not able to cover up electricity cost
let alone a little profit

I pluged my vegas direct in the air duct. 2 powerful fans ensure there is always negative pressure in the duct. Power supplies are also fed to this hit air duct. This way works really nice for me and was cheap to do, the cooling gains are massive, thekey to proper cooling is thatall heat is extracted directly, and nothing goes back into the room, everything must be plugged and sealed

Umm.. why are you running the fans on auto or such low speed ? are you trying to save fans live instead of GPU ? turn that to 100% ;D

with so many cards mining a while, I bet yo could afford some propep watercooling system, not DIY one.

Ambient air FTW.

It's sad that the low delta T makes it near impossible to reuse the heat to something (e.g. create some hot water, although cold showers is called for in 100+F :) ).

A mining shed would be a good place for an air/water heat pump "outdoor" assembly, recouping some (very little of course) of the power lost out the vents.

Optimal temperatures are different for different components

- Unrecommended temperatures are always indicated in every technical document of the component (also, maintenance T, storage T, storage and maintenance humidity, allowed altitude).
- Optimal temperatures - from the dew point (the lowest temperature at which condensation condenses) and up to 21-26C (usually, indicated in the passport). Capacitor is the most suffering element in hot temperatures. Electrolytic capacitors are widely used because of their low cost. You can take a look here what happens to them when they overheat. https://ru.m.wikipedia.org/wiki/Элeктpичecкий_кoндeнcaтop
- Accordingly, unrecommended temperatures are the ones higher than indicated in the technical passport.
- Using your devices in high (or low temperatures) may lead to premature failure (at high temperatures there is an accelerated degeneration of semiconductors and destruction of the elements) and change of embedded characteristics of the whole rig or its parts (the most usual example - decrease in the maximums frequencies).

his gpus are at like 65 degrees thats a great temp, idk what the fuss is all about
even 75 to 78 is good in summer

Well GPUs can run at 40-50C ambient temperature especially the RX series which only consume slightly over 100 Watts.

The bigger issue here would be if this was an office or apartment or house with human habitation, then it would be brutal.

Maybe if you were pulling in $10/day/GPU and you had like 100 GPUs then it would be worth living in a house that's 112 degrees but at these currently prices, I am pretty sure most people just turn off their rigs.

My temperature is about 37C, but it is very humid.
