...you havent responded to ne of it. care to comment?...

You haven't said anything to comment on.
You make wide-casting speculations with no data. Terms like "hotter" and "cooler" are relative and without context.

Yes an "underclocked" miner in a room that is 60F will be "more efficient" than a stock clock in a room that's 78F, until you calculate the cost and "efficiency" rating of cooling a room to 60F while running a 5,000BTU heater inside that room.

You go on about Googling random anecdotal posts on the internet where miners are failing because they are too hot, while ignoring that the majority of them are being run in ambient temps that are too high to begin with. Would you put a gaming PC in a 100F room and expect the gfx card to hold out while running at 100% usage 24/7? (That's rhetorical, because we both know the answer is, "No!")

You claim that ROI is none of my concern, if you truly believe that, then my beliefs (which are based in the factual realm) are none of your concern and you can go away now.

i have proof that they run the miners hotter. not only was it posted in this thread but i also have pre auto tunes batched and post auto tunes batches and the temps are very very different. the post auto tuned batches clearly slow the fan speed down to make them run at a desired floor temp programmed into the firmware. the pre auto tuned miners run at a constant speed with no such floor in the temp config. i know post auto tuned miners can have more chips as well which generate more heat but if that was the cause of the almost 20 degree difference the fans on the auto tuned miners wouldnt need to have a floor set because they would run at a steady speed so those extra chips arent the cause of the spike. if i run the fans at the same speed on both miners the temps are about the same and hover around 80-90 degrees at the chip. some are lower than 80 but it really has alot to do with heatsink placement and if they are perfectly straight. so i used miners with the same speeds so the numbers would be similar to see if they mirror one another with ever so slight differences which again can be blamed on the placememnt of the heatsinks.

i didnt claim a single thing related to efficiency as far as i know. its been a while but lowering the clock speed on miners as far back as the s3 didnt increase efficiency one bit if im remembering correctly so i wouldnt claim that. maybe thats where your confused? you can make them more efficient but that takes mods using either a pencil or swapping out components so that is beyond what the normal hobby miner is willing or even capable of doing.

now to correct you fully...i (and multiple others) said a low power mode would be beneficial for people running their miners in a warmer environment for example in the summer time and their ac unit cant efficiently cool the house and all the extra heat being pumped into it. without a low power mode what options do they have?? well only 1 to be exact....turn the entire miner off which generates $0 for the entire time it sits collecting dust. every ac unit has a cooling capacity (and heres where your choice use of the acronym btu comes into play) and that capacity cannot be increased ever...sure there are ways for example swapping out the unit with a larger compressor but that isnt feasible for a hobby miner so for the sake of this convo we are considering that impossible. anyway if the ac unit can handle a portion of extra heat then a low power mode will effectively allow him to run the miner during these conditions vs not running it at all and based on your roi argument (not much of an argument since bitmain doesnt care if we roi or not) that would be the end of the god damn world as we know it lol. or are you saying running some isnt better than running none at all??

a gpu fan isnt make to move large amounts of air over the heatsink. they can move alot for their size but there are limitations. gpus arent supposed to run at 100% all the time...they can handle short bursts of 100% power being pushed through it but not constant. even in ice cold temps 100% usage isnt good period. but the main convo isnt about gpus its about s9's. gpus are also not locked by their firmware to run the miners at a steady 100+ degrees c now are they? but s9's are firmware locked to do just that. you admit higher temps arent ok for video cards but you dont agree that the temps these machines run at isnt safe too?? how can it be safe for one and not safe for another?? they arent using components designed for ballz hot temps but even if they were what is the reason for rampin fans up and down from 30% to max sped every couple of seconds?? what benefit would have have vs running them at a steady constant speed which will dramatically lower temps on those miners. running them cooler doesnt lower the hashrate....i tried it and my ato tuned miners run at the same hashrate when the fan is constant and when the fan ramps up all over the same place so what justification is there for adding stress to the components??

i claim that the roi isnt an argument. bitmain didnt remove features from the config page to ensure we saw a return on our invesment. do u believe bitmain has our best interests in mind? why would they care what i make from their miner? i can go buy a brand new s9 right now and put it on a shelf in my basement...do u think bitmain will email me asking why i havent turned it on yet to start mining coins?? nopeeeeeee....they got their money.....so running it at a lower speed and making less isnt a factor in their decission making. they wanted to run the boards hotter but for what reason? Huh

?

you say there isnt anything to reply to but i have asked maybe 15 questions none of which get answered. others asked questions that werent answered either lol. uk what ur doin. ur in a corner....u can either keep tryin to talk around in circles or u can stop replyin....one or the other....doesnt bother me either way.
