    Full load they sit on 79C master, 86C slave. Takes literally 5 minutes, of both going full bore, they nudge over 90C before the fans wake up to spin to full.

    Mining eth at 58mh/s, 295W wall draw btw. Return at current price 790%

    Since when has running an electric heater made money? This world is bonkers

    Seriously, noone can answer that for you. Do you have the skills and tools (and patience) to follow my mods, accept the risk and the ~1200usd cost (less any sale of existing gpu/s), for the return of a 1080ti equivalent in your laptop?

    Put some liquid metal on it. Needed bugger all of the stuff, heat sinks fit really well, probably due to small size and weight (compared with the p870dm ones I had to repeatedly manhandle to get appropriate core contact with)

    While it idles a good 10C less, temps under load dropped maybe 4-5C. I suspect because the limiter is heatsink fin area. Cpu fared better, couldn't get it over 73C at all and it didn't even spin up to full.

    Still annoying the GPU fans don't spin up to full to settle on a steady load temp until the slave reaches 90C.

    If you are just mining, leave it turned upside down with the bottom off and a desk fan blowing on everything to help keep it alive as you abuse it :p

    Dammit you just reminded me I meant to get the calipers out and measure up the wing and tab so people like yourself can know beforehand with certainty about fitting. Sorry to dangle that at you as it's unlikely I'll get a chance before later next week!...

    Try Unigine Heaven few runs and check the temps then. Would be awesome if it still be cool. Then my 4year old would see another upgrade in future. 680m sli -> 980m sli -> 1070 sli

    I would count a single 1070 as a nice upgrade from 980m sli.

    My calipers' batteries are flat and it's actually hard to do with the heatsinks on. I'll get around to it when I start disassembling it for vBIOS flashing.


    Hmmm a sidegrade in terms of performance, my overclocked 980M's were generally a tick faster than a stock power limit 1070 in @the_gh0sts' exact same model P870DM - unless limited by SLI. A single 1070 will use far less power though

    However if you get the 1070 through the ebay link I did, and sold the 980Ms, it's highly probable you'd end up ahead in $ terms.
