well I just installed a rx 580 inside the same case as my 1070. The 1070 is a blower style fan that keeps cool at its overclocked speed
the rx580 dual fan by asus gets HOT its running at 76 C while my MSI aero 1070 runs at 65 C
the rx runs to hot, I can see why BOTH amd and nvidia are now putting in blower fans while the cheap after market gtx are using a cooling system that makes the entire PC hot
its this hot and its in middle of winter, I am seriously considering selling both 1070 and rx 580 and just getting 2 water cooled 1080tis and be done with it,
no more fans, no more fans breaking, no more worrying about the heat in the summer.
at this rate in the summer the rx 580 will die it just runs to hot
IMHO, the open-style fans are fine as long as you have an open frame mining rig and run an external fan perpendicular to it. The 10-14 inch fan adds an additional ~50W to energy cost but they work well to force hot air out thru the spacing between graphics cards where hot air gets trapped.
Ive noticed that even tho open-style fans have heatsinks that are designed to force hot air out thru either the back or front end of graphics cards, when you have 5-19 cards stacked in parallel the temperature kinda get a little bit higher going from the first to the last in the fan direction.
im shocked there isnt more water cooled options. thinking of making 2 PCs with water cooled 1080tis, so 4 1080tis in their case, sitting in a corner nice and quite. I can put them in different places. its easier for a pc to sit in a corner and nobody notices it, If I go on vacation for 2 months, I feel my water cooled GPU will be ok in the heat.
but I think the blower fans are like new tech, 1 fan does a better job in the case.
but then I dont know how these blowers will work when its 90 degrees out. the price of a regular 2 or 3 fan 1080 ti is as much as a water cooled one, I never had water cooled anything but if I had the money all my GPUS would be water cooled
https://www.youtube.com/watch?v=8s_je7-BIEcim still seeing how I can do this with 2 1080tis water cooled but I dont want anything to break, I dont see many people mining with water cooled so Im a little cautious about spending on water cooled gpus
could I get 2 of these and put in case and not worry?
https://www.youtube.com/watch?v=4ugGv0kw8pQIn my opinion, the water cooled cards are more expensive and I can't justify the price, when I can buy any other style card cheaper, and keep them cool. Blower, or other. I don't use computer cases though. I use open air frames with six gpu's in each with a $15 usd dollar box fan on the back of each rig to blow the hot air off of the cards.
You also have the worry of water leakage or the cooling system failing. I had a friend was all about water cooling his gpu in his gaming pc, until he started having problem after problem with pumps.
I'm still testing solutions for removing hot air from my mining room. I currently have a box fan in the window sucking hot air out, but I think I need a more powerful fan if I'm going to use that method when outdoor temps reach 90-100F in the summer. Leaving the door open in my mining room also allows a lot of the hot air to move out of that room into the rest of the house (with mining room windows open, but we're talking 30-40F outdoor temps here right now. We shall see.
Other options may be a ceiling exhaust fan to suck hot air out of the room into the attic. Or a wall exhaust fan to suck hot air out of the room and push it into the house. Or even a movable temporary solution of stackable box fans in the door way of the room to suck hot air out of the room into the rest of the house.
