Title: GPU placing in mining rig Post by: dvince on January 21, 2018, 09:44:39 AM Hello,
I would like to hear your opinion about this 8×GPU placement in mining case: http://i64.tinypic.com/33o17rt.jpg As I saw in many videos with temperature measurments, the classic parallel positioning is interfering with each GPU cooling. The GPUs between are 15-20°C hotter than the GPUS on the left and right corner. With this placement every GPU is blowing hot air outside the case and not between. What do you think?? Title: Re: GPU placing in mining rig Post by: 0xcosmos on January 21, 2018, 03:14:51 PM why both the air direction is out
one side should be intake fans and other side should be outtake fans Title: Re: GPU placing in mining rig Post by: [YAZ] on January 21, 2018, 03:26:28 PM why both the air direction is out That's not a fan's, that's is GPUs. OP drawing a vertical GPUs positions.one side should be intake fans and other side should be outtake fans What do you think?? It depends on GPUs airflow, what your GPUs are used? Many concepts of the cooling system, but it depends on a few factor. Ex, cards airflow, what kind of a rig you are used, rig dimensions etc. Title: Re: GPU placing in mining rig Post by: AngelSky on January 21, 2018, 03:45:57 PM Hello, I would like to hear your opinion about this 8×GPU placement in mining case: http://i64.tinypic.com/33o17rt.jpg As I saw in many videos with temperature measurments, the classic parallel positioning is interfering with each GPU cooling.

Most of the cards will bear upto 70d Celsius So if you just keep the table fan under the cards you placed in the rig means you do not need to worry about the placing direction. You need to keep fan facing outside of windows side is enough for the placement you required. I have seen the design image shared, Even that is fine to place in the rig. Please go ahead make the rig in aluminum stick. Wooden will not be works better for long time. vibration issue may comes all the time in Wooden rig.

You need to build a solid rig frame. since sometimes we need to set GPU fan speed to 100% to keep your cards at a normal temperature. So it will increase vibrations at your cards. Title: Re: GPU placing in mining rig Post by: dvince on January 25, 2018, 10:15:41 AM I will be using 4 nvidia 1080 and 4 1080 ti.
Rig dimensions will be 100cm×40cm×50cm. I will put a normal room vent for airflow between rig for cooling back sides of GPUs. The GPUs will be fixed with two screws at the top. I dont think it will vibrate. http://i64.tinypic.com/2z518jm.jpg |
