The Asus ROG GL504GM Hero II runs cooler, quieter, and longer than the GL504GS Scar II
If given two identical cooling solutions with different loads, the solution with the warmer load will be working overtime compared to the other. It's inevitable that one solution will be hotter and/or louder.
Such is the case with the Asus ROG GL504GM Hero II and GL504GS Scar II equipped with the GTX 1060 GPU and GTX 1070 GPU, respectively. Both SKUs share the same chassis design with very similar cooling solutions even though the TDP gap between the GPUs can be as large as 30 W to 40 W. Consequently, the GL504GM is able to run cooler and quieter as there is comparatively less heat to dissipate from the less powerful GTX 1060.
Based on what we've seen from the two SKUs, users can expect the GL504GM to be as loud as 47 dB(A) when gaming compared to 51 dB(A) on the GL504GS. Both the CPU and GPU will run cooler as well at about 66 C and 68 C, respectively, compared to the low 80 C range on the GL504GS.
Additionally, the GL504GM includes Nvidia Optimus for more power savings and a longer battery life when not gaming. Our tests have shown that the system can last for almost 6 hours compared to less than 2.5 hours on the GL504GS when subjected to similar WLAN loads.
The two SKUs of the Razer Blade 15 exhibit very similar characteristics to the Asus GL504GM and GL504GS as it was discovered that the Blade 15 with the GTX 1060 would also run cooler, quieter, and longer than the Blade 15 with the GTX 1070 for the very same reasons.
