    It does, when I disabled the Turbo clock my overall temps went down by 10-15 degrees, including GPU.

    You mean reducing CPU usage in power settings, and by what amount?

    If you set CPU to 99% it will basically disable turbo boost. making CPU run at 2.6GHz only, this will help in many games is GPU throttles, since GPU is more important than CPU for midrange laptops.

    I'm owner of one GL551 as well. I bought it yesterday and I already came across the problem ...

    I've got the same problems spoken here. Play GTA V is completely impossible in this PC . Due this throttling of 960m in less than 5 min I have the GPU to run about 400Mhz which is intolerable.

    To solve the problem while the asus makes available a bios update my solution went to undervolting the GPU and change the maximum CPU performance to 99 % in the windows.

    So I can play with the graphics card with always clocks above 1000Mhz + which is not what we want but it is better than the previous 400Mhz . It is a large increase in performance, 20-25fps to 45-50 with the same options.

    Simple solution that helps: use cooling pad for your G551, prefer these with 70 CFM air flow or more (Cooler Master X series?).
    But this is not enough.
    As the air intake vents in G551 are small, just unscrew and open cover that gives access to memory & hdd.
    Put your asus on pad then - you will see really high improvement of temperatures and thus - FPS in any game (tested on The WItcher 3)

    I tried cooling pad also - turned out to be rather pointless, no effect. Its the inner temperatures what matter, cooling pad cant reach there in any way, it just blows air to the plastic case basically.
    Listen, this one-fan-cooled laptop is just not what its advertised for - its just a powerful multimedia device, not a full - on gaming PC for long gaming marathons.
    I had gtx860m and actually it ran the GTA 5 pretty well, just gradually performance dropped from 50-60fps to 30-45 fps and started to stutter. But hearing from other users I think 960m is even worse, seems like they made it even more temperature-sensitive than 860m was.

    @MafJose - basically U R right, but after I removed mem/hdd cover even using Glacier 200 Cooling Pad (<30 CFM) temperatures drop, especially while long tests/gaming.
    For instance I improved my 3DMark Fire Strike from 4716 to 4799 (almost 4800). With cover closed, or opened but no pad running - I have still around 4710-4720. With both (pad running, cover opened) never worse than 4780.

    In Witcher 3 I have about +2 FPS at average with this (but I play with constant 30 FPS so I decided to use my additional computing power for maxing all graphics settings except Hair Works (still have it off, not enough computation power of GPU).
    So this works for me.

    Yes, maybe that way it could provide some cooling, it also slightly depends on the design of the cooler.
    I also tried to just lift it higher so it could get easier access to air, did not help either.
    In conclusion it has to be done right internally by manufacturer, G751 has it right but its alot bulkier due to that.

    Yep, the only solution for 15 inch design or smaller is to provide external thermal port. I demanded this years ago - simple copper bone ending that goes via one vent slot (left or right) with about 0,5 cm2 copper surface and simple screw mount. I did one self made for me in other laptop (much smaller Asus UX21), so I can have external cooler, sucking heat from copper bone inside. This works like hell and is simple in design. Of course you need external cooler but it can be any size and sink all heat.
    I plan to do a test version of such heat port so I will publish photos and results. But surely there will be no throttling at all because GPU could not reach 74C. No way.

    I plan to buy asus g551jw but this issues make me very confuse and from what i read the asus g551jm also have a heat issues problem bcoz single fan uses in this two models

    So which one better if had to choose between asus g551jm with gtx860 4gb ddr or g551jw with gtx969 4gb ddr??

    Any other model recommend( max 15.6 inches for portability)

    Thanks for the advises
