The katana  stands at this second one comes on weds.

and I may get 2 more next week I did some facebook talk  with them.

 DO PUT A GFCI (either a replace-the-outlet type or replace the breaker in the panel doesn't matter which) on any circuit that serves a fan in a window.

 However, if the window is on the "normally downwind" side of your home, the screen should keep any water from entering your home that way.


 Having both intake AND exhaust fans is generally redundant - IMO go all one or all the other, don't mix-and-match or you're wasting electricity for little or no return.

 Pushing or pulling air in the same direction as it's natural flow (either through heat rise or wind pass through) works better than trying to fight the natural flow.


 To Citronick:
 I like the Gigabyte 2 fan model 1070s https://www.newegg.com/Product/Product.aspx?Item=N82E16814125875 which are fairly often on sale for about as low as any other 1070 model but seem to clock as high as any of them.
 Their ITX 1070 model https://www.newegg.com/Product/Product.aspx?Item=N82E16814125893 isn't quite as fast, but works VERY nicely in the "outside" slot of my 3-card rigs for heat management on the middle card as it's only about 7" long and leaves one fan on the middle card completely clear.

Phil  did Galax get back to you about more Katana's?

   pull from the window  go out the roof.


if rain is an issue.  make a   hood to block the rain.

intake fans are less important then exhaust.  and exhaust out the roof  is best as hot air rises.

It's a risk, up to you to assess how small or large.  GFCI the circuit that serves the room, maybe.  Possibly just as easy as a single electrical outlet changeout, don't remember for sure.  You seem to like Home Depot, so http://www.homedepot.com/p/Leviton-20-Amp-125-Volt-AFCI-GFCI-Dual-Function-Outlet-White-AGTR2-W/300049855.  $26, and a decent industrial grade outlet has to be what, 4-5 bucks tops now, my WAG?  I definitely regret all the ones I've replaced with dollar ones now, just because of house cleaners yanking vacuum cleaner cords out the easy way.

Hm yeah I could do that too. I didn't even consider that I always just assumed it would be best to go from the window.

The door leads to another interior room though, that's kinda hot in general. I may be able to intake air from the roof and disperse it through ducts at ground level though. And use fans on the ground to push that cool air up.

water can easily get past the screen, they just gonna get a bit smaller..try it, sprinkle some and see the results..

considered thinking about drawing air from the ceiling?...fans are still on the windows(pushing air out of it) air will be pulled from the door and ceiling as fans in the windows exhaust hot air.

Yeah that is a concern for me. However I have the window screen still on so that should help.

there is a danger of pulling rain water too aside of cool air from the window/s since the fans are giving them extra push.

and he must be constantly watching it...in case if it hangs hehe

  the zotac 1070 mini gets a good buzz.

I do not have one

but the zotac 1080 mini is good and I have that.

What core oc are you doing in those benchmarks?

And ya seems like mem clock doesn't make a difference, does -300 just save heat/power?

I have a pair of 1080ti FE's in a closed rack mount case and they get the following:

Power limit of 50% gets me ~525 sol/s and 4.2 sol/W @ 120W per card
Power limit of 60% gets me ~620 sol/s and 4.1 sol/W @ 150W per card
Power limit of 70% gets me ~670 sol/s and 3.8 sol/W @ 177W per card
Power limit of 80% gets me ~700 sol/s and 3.5 sol/W @ 200W per card
Power limit of 90% gets me ~725 sol/s and 3.2 sol/W @ 220W per card

It seems to me that these 1080ti's love core clock, and memory speed really doesn't make that much difference. I also found -300 mem was good

In a closed room, yes, you want BOTH those rules goin on if you can.  I think I'd put the heat generator right smack in the middle of thee room.

The home depot cheaper fan, spent that kinda money on fans and ran em 24x7 and dead in 2 years or less  That's why I turn my wife's off every morning. Ain't no wind tunnel.

Go stand in front of 3500 - 5000 cfm fans at home depot or lowes, get 'em to plug em in for ya.  I don't think you'll be real impressed.  Ain't no wind tunnel.  Could be enough but won't know without including size of openings and cfm in the calcs, and prolly also BTU or estimate, avg ambient air temp outside and inside with no heat and cool running at all, etc.  Attic fans are awesome IF you open every window in the house, yer air isn't dirty, and you have a high temperature differential inside versus in. Like 20-30 degrees. That one is not much more expensive than a good bathroom exhaust fan nowadays.  I think you are mostly paying for the metal there.

It could work but you don't wanna overspent or underspend to get the job done.

Most HVAC forums are filled with tradesman that don't really like to give DIY advice in varying degrees but since you aren't working on a furnace or an air conditioner at all they may point you right at the correct formulas if you include all the measurements mentioned in this thread.

back to the drawing board over here.... I think I will just go for a slightly chubby 1070 then - any recommendations?

Thats a $6K rig .. hope the rig can touch at least 5000 sol/s 

I know;  after seeing the hashrates out of just 5x 1080's, I can only imagine how the ti feels when you get the pools payout 3 times a day... lol.

wow.... 6 x 1080ti is an incredible$ rig

Post some pictures will ya?

yeah  I should have also really looked better at the facebook message  back on May 1 or May 2.

ah  such is life.

i meant external fan.

GPU fan is 63%
