So, after finally jumping on a Samsung 960 Evo 1 TB SSD ($339 at MicroCenter btw), I was able to install a slim Scythe fan behind my Zotac GTX 1080 GPU, and replaced my big slim 120 MM fan providing primary cooling for the heatsink. So so far here are my mods:
- Slim 120mm Scythe fan behind the GPU
- 2 x 92x14mm Noctua fans controlled with PWM adapter for primary heatsink cooling
- Arctic 0.5mm thick thermal pad contact between heatsink and aluminum front bezel
With the addition of the slim Scythe fan, and thermal pad mod, I have seen my temps drop from 87 degrees celcius on full load to 78 degrees celcius (22 celcius ambient). This is with my S4 Mini in a horizontal position, on some feet I made with the GPU facing the table. The case itself is propped up about 2.5 CM.
Considering the form-factor of the card and case, and the horizontal position, I am pretty happy with these results. I was honestly expecting a bit more, and maybe a custom fan curve can help with that. May try playing with afterburner later.
