I've managed to setup Slackware 14.2 on my main cruncher and using the special apps for my two 1070's. All is good and running smoothly so far, however temps are high: 80+ and 70+ celsius (fan speed around 54%).

My display is connected to the intel GPU port and not using nvidia. nvidia tools for fan settings only work where they are connected to an X session. Which leaves me with no options to modify fan speed. I have found some scripts that creates virtual X sessions and modify the fan speed then kill the session, but none of them worked.

any ideas?

Why not connecting your display to one of your GTX 1070 ?
If so, you just need to add an extra line :
Option "Coolbits" "4"
in each of your "Device" section.
Reboot and you'll be able to control fan speed from nvidia-settings.

I have one GTX 1070 (MSI Armor) : 70 C
The next one GTX 1070 (MSI Gaming X) : 80 C ...increasing fan step to 90% make temperature falling to 75 C

I'm a little bit disappointed by the MSI Gaming...reviews were claiming maximum temperature of 70 C

---

I haven't tried this but it might work without an xscreen...
sudo apt-get install nvclock
- To change GPU fan speed, write this:
nvclock -f -F 70
- 70 is % of speed

I'm a little bit disappointed by the MSI Gaming...reviews were claiming maximum temperature of 70 C

Most reviews are running games, not crunching Seti work. Rather different workloads.

that's what i ended up doing, but I think my current solution would have worked anyway. the problem is even when connecting the display to one card, you still need the same for the second one so you can control both. So I've set coolbits and I created a virtual display for the second card. I am assuming i could have done the same for the first card while leaving the monitor on the iGPU...

I've had two MSI 780 bought in 2014 and 2015, back when the 780 was expensive and a flagship. Both burned out at some point... I'll leave it at that... I am currently using ASUS 1070, the ones with supposedly 4 times fan durability:

i am not using a debian derivative, but the below works once you assign a monitor to the cards:

nvidia-settings -a [gpu:0]/GPUFanControlState=1 -a [fan:1]/GPUCurrentFanSpeed=60 -c :0.0

or nvidia-settings gui tool will do the same...

This will help with cooling and looks cool NVIDIA Case I think Petri could use one :)

It's the same case as mine (without the graphics), and I love it.

i've got this

my 4770k was giving me lots of overheating issues, which was solved by installing an H100i back when I got this pc. my 2x1070's are ok @75% fan speed but i will be adding a 3rd soon. we'll see how that goes.

The way the motherboards are designed, it is impossible to avoid this. 2-4 GPU stacked on top of each others... someone should make a case like those cube things. one segment for motherboard, cpu, drives, and one separate segment for 4-8GPUs, some pci cable to connect them, etc...

Hi all,

I'm divesting myself of my NetStor PCIe expansion chassis model NA260A-GPU-R and the Galaxy GTX 680 that is currently in it. You can read more about it here. http://www.netstor.com.tw/_03/03_02.php?MTAw#

What this thing allows you to do is add up to 4 more double-width GPUs by putting the host adapter card into an 8x slot in your computer. So in theory you could have 8 GPUs in one machine using this expansion chassis.
<snip images>
This unit sells for $2500 new and I'm asking $1500 + shipping so I though I would give you all a crack at it before I post it in the general forum or put it on eBay.

A good idea, but a little pricy.

I'm surprised your running 80C with 2-200mm fans. Mine holds quite good at mid 60s on it's own

interesting, they already exist... i'll check them for future projects, if it is feasible to have it shipped to where i live.

i have 4 fans on top (including the ones for the h100i) as exhaust, 1 side fan intake, 1 front fan intake and 1 back fan exhaust. i've also spent some time testing different fans configuration, and at some point added a bottom one. Not much has changed.

GPU1 had the same temp as yours without any modifications (i am assuming that's the lower one) but GPU0 had an issue (i am assuming due to it being close to the other one). it was much worst when i had 2x780's. also spring decided to show up for a couple of days early march, we're at 25 degrees celsius here.

Hi,

I've had to put some 'spacers' between the cards. Matches, plastic pieces of something, toilet paper, .. You name it. Something to prevent the cards to come too close each other. And yes, I've seen the professional screw bars with adjustable brackets holding the weight of the other end of the cards. Nah, too much work. Just stick something there in between to help the air flow.

Next I'll screw off the half backplate option (1080 has one) before the summer hits here and then I'll build the professional adjustable spacing device. But I hope one of my 1080's melts down before that so that I can get a 1080Ti as a replacement.

Been checking out the reviews of the GTX 1080Ti- impressive beast.

. . That would be a good idea with a radiator to keep it nice and icy cold.
