Hey guys, I am new owner of G751JY as well but also the unlucky one since I am having the throttling issues as few others posted on forums there. So far games that dont stress CPU that much are fine also the ones which are capped at 75vsync (WoW - CPU at 77°C after 3hours, Skyrim - 75fps cap CPU at 81°C max) but main problem are games that dont hit that cap on ultra and use 100% of CPU/GPU almost all the time (Far Cry 3 - 70fps - 94°C CPU).
As far as I read, the only half-way solution at the moment is undervolting the CPU and reducing the multipliers when 3 or 4 cores are active right ?
Anyway no idea why they made the fan working at 3100RPM max when just rising this to 3400RPM would fix the issue in my opinion, since the temps are just slowly rising because of acumulating the hot air inside.
Also my iddle CPU temps are fine 32 - 40°C , it is just maximum load that causes these issues. Also GPU temps are fine as well - 78°C is the highest I have seen yet.
