My 7x 1060 GTX GPU Rig is not functioning well. It ran fine for like 4 weeks. Now every time I turn it on, it starts mining like normally, but after a few minutes Im starting to smell plastic burning... there is no smoke however, and the GPU temps are fine <60C. The fans of the gpu's start to make very much noise, and the teamviewer connection gets lost. Then I have to force shutdown the system. Anyone knows whats up? Im afraid there got dust in my cards. Ive already blew them clean with a compressed air can....

A bit of dust would not cause the melting plastic smell you are referring to. I am betting you have a wire that is overheating somewhere and that smell is the plastic jacket around it heating up. Double check your wiring, make sure you dont have too many risers running off of a single power source etc. Let it run for a few and feel around for hot wires.
Also, move this to the proper section. This section is for bitcoin mining and most people are just going to tell you to move it anyway.

Stop buying industrial miners, running them at home, and then complaining about the noise.

riser melt = 90% sure examine them all

riser melt = 90% sure examine them all Yep, check your risers. Also, check your PSU. you can figure out what device is the culprit by smelling them individually. Are you running a PSU with a ~20% overage on your total consistent wattage draw?

Thanks for the replies. I'll check the risers. For PSU I'm using the Corsair 1200W. My rig only uses about 750W, so I think this should be fine.

I wonder if the settings on your PSU are correct? i mean those corsairs have some kind of ilink where you can adjust power, cooler and etc check there if all settings are ok then check the risers connectors - 100% something fishy there. maybe somebody touched them, and now bad connection somewhere check cables comes to PCI-E 8 pin connectors to your VGA cards and check those cables in your corsair, sometimes the problem is there. if the temps on vga are ok - then only those 3 places to check left

I haven't modified any settings of the PSU. I bought this rig ready to plug&play. It was running stable for 2/3 weeks, and then I left for vacation. When I came back these problems occured. I'm going to check and maybe replace the risers, however I'm still not sure which one is causing problems. The smell is all around the rig, I can't identify where it comes from yet.

I noticed the burning smell might be coming from the PSU. Is there anything I can do about that or should I just buy a new PSU?

If your PSU smells then you must assume it will fail. Do not use subpar off-brand cheap power supplies. When power supplies fail they have the potential to take the whole system with it.

I meant PSU not GPU sorry Anyway its a Corsair HX1200, no more then a few months old.. ridiculous. I dont really feel like buying another 200€ PSU just to find out if thats the problem.. any other options? Does it really need to be 1200W when my rig draws 750-800W?

Have you found the actual point of failure? If you smell burnt plastic, it's unlikely to be inside your PSU. You might have overloaded one cable (how many GPU risers have you attached per sata-cable?). I had one of the sata connectors melt because I had 3 risers attached to 1 sata cable (everyone's a noob at some stage, right?).
Needed pliars to disconnect the melted plastic connector from the PSU. Re-did my wiring, everything worked well ever since (even the PSU).
Most importantly, turn everything off if you smell burnt plastic ASAP. Be granular in your search for the point of failure. You'll find it ultimately. Even if you have to disconnect everything.

Check connection from what you say it;s in imperfect contact someware the problem is either the consumtion on 1 cable is to big fir it;s design or imperfect contact: sata to psu cable sata to riser pci-e conection at gpu (not all pins make conection) also defectig soldering on riser might be a problem or very rarely on the gpu the problem spot will heat up, u will feel it at the hand even get burned if direct contact also if you have a wattmeter there will be a power consumtion increse when you use the connection with problem, anyware from 20w-150w increse depending of the problem the problem might also be caused by the conection board inside the psu , from the rail to all the plugs, if the pins where forced or used to much (in out and so one) wil get lose and only make contact at 1 small point, i sugest u check everything until u find the problem, the next step if unrezolved is a fire. also ar the cards tunned for energy saving? 750 tested, or just by word? if you are willing to post detailed info and pictures it would help to faster solve your problem, riser model , arrangement in connections,

Maybe the power wire for the fan is making contact with the fan or the heat sink. Until the system is running a few minutes there is not enough heat to affect the wire, but after a minute it has reached the level to start heating the plastic up. I would disassembly everything and put t back together again from scratch, new heat gel and everything. It can't hurt.
