    GL702ZC dead GPU

    Hi all,

    I got my GL702ZC about 3 weeks ago and today while playing Deus Ex: Mankind Divided the screen suddenly turned off and it hasn't turned on since. After rebooting the laptop I could still access it over the network but the GPU seems to have dropped off of the PCI bus entirely, it's just not there any longer. I was playing without headphones on so I could hear the fans the whole time and while they were running they never went insane.

    After rebooting the fans did seem to go to 100% the whole time, but I was able to recover my data. The fact that the laptop never went to 100% fans before it broke suggests to me that at the time it broke there was no thermal problem.

    I've sent in the laptop for RMA and I hope to get a new one quick. I was wondering if anyone else has had any problems with this model. I've seen several pictures online of the motherboard and mine has two loops of heatpipes over the memory slots, but I've also seen pictures where there are no loops over the memory slots and there appears to be extra heatpipes to what looks like VRMs?

    Could the fact that on this model the VRMs aren't cooled be causing me issues? Does anyone else have a model without the loops over the memory slots?

    Thanks!

    Well, RMA went smooth as butter. I'm getting a new laptop with same-day delivery. I have no complaints about the service at least!

    Here's hoping that my suspicion about the VRMs is unfounded.

    This is eerie.

    My GL702ZC also had a breakdown in terms of fans suddenly running on 100% after playing Mass Effect Andromeda for multiple hours.
    I shut down the game, restarted the computer, etc. (even tried a clean Windows install)... the works, but the fans just kept running on maximum immediately from power-up.

    My GPU (RX 580) on the other hand seems to have continued working fine ... but this is now another report of a same problem occurring on a same laptop (with fans running on 100% all the time).
    It looks as if Asus might have messed up the cooling for the GPU or the system at large.
    The RX 580 is not particularly demanding... its limited to 68W... and other laptops have much higher TDP requirements in terms of GPU's but don't have same problems or noise issues.
    This seems to me like Asus cheeped out on the cooling and the battery (oh that low power integrated battery). Granted, they also used a relatively mediocre SSD (which I can let slide as its fast enough), and never gave us a dual-channel 16GB or 32GB RAM on offer (for the same price btw).

    I don't get this... the mobile 1060, 1070 and 1080 have much higher TDP's (and power limitations) than RX 580 in this laptop... why is it so difficult for OEM's to create proper cooling for efficient AMD hardware?
    The CPU is 65W yes, but if you noticed, the CPU is not particularly demanding either... systems with say 45W intel i7 and 1070 will have a TDP of about 155W... which is larger than GL702ZC's 130W.

    I RMA'd my own unit as well last week (had it for just over a month though) and they said they will keep me apprised.
    I also told them that I am worried that whatever issue might have caused this problem could happen again and asked them to redo the cooling if necessary as I obviously want to avoid the problem from happening again.

    Since I have access to their support now via email (which is prompt)... I will breach your own case problem with them as well and say that I'm worried the GPU might also end up failing on my laptop since the problems are similar.

    It might kick them in the rear end and redo the cooling assembly entirely - as it seems to me that this could be an issue of waste heat damaging motherboard components (affecting solder, etc.).
    Or it could just be that we got the early models that have the most issues.
