Hi guys,

I know this may seem a bit out of date, with the RTX 2080 Ti's already being out... But I currently have a EVGA GTX 1080 Classified which my pride and joy... But it has been running really warm since I bought it and EVGA won't do anything because "It's within specifications". The temps are 75°c-82°c while gaming, 88°c during HeavenBenchmark and 92°c during Furmark. (Ambient temperature is 20°c) When I do the synthetic benchmarks, I have all fans running at 100%. My case is a NZXT S340 Elite with 2x SP140 for intake and 2x AF120 for exhaust. I will have them running at 100% as well as the GPU and CPU (Via 212 Evo in Push/Pull).

I've currently got a medium OC on my card already (+100MHz core, +250MHz Memory) and it will boost to 2075MHz while gaming and 2050MHZ or lower during HeavenBenchmark. My problem is, I know it will run faster with cooler temperatures because when I start HeavenBenchmark, it will jump to 2150MHz without crashing but because of the rising temps, that falls to 2050MHz or lower. Also, I do have voltage, temperature and power limits maxed in MSI Afterburner (My GPU has weird issues with EVGA XOC) as well as a heavy custom-fan curve. I also have the GPU in the Classified BIOS, which "should" boost the power limit to 130%. Don't know if it does.

I've now come to the conclusion that I want to change the cooler. I have already changed the thermal paste twice with Arctic MX-4 but this made no difference in temperatures. I've thought about doing a custom loop specifically for the GPU, but there are no officially supported blocks that I am aware of, and although the 780 Classified will fit, I do not have the money for all the water cooling parts. I also don't have the confidence to water cool, especially when my £500 GPU is at stake.

So, I have come to the conclusion the next best thing I can think of is to with the NZXT G12. Only issue with this, I don't know if it is supported, being the 1080 Classified is extra wide because of that 14+3 power phase. If I were to buy the G12, I only have a few questions... Which AIO would be the best fit? I am after a 140mm so I can still use my SP140s I use for intake. Also, how am I meant to cool the memory and VRMs? I'm assuming I get some thermal pads and use some small copper heat sinks, but would that be enough? I know it is going to have active cooling with the fan that comes with the G12 (I'll be swapping that for a Noctua one anyway) but I am wondering, will it be enough cooling for them?

If you guys could lend me ANY advise, I'll very highly appreciate it.
Thank you!

Thank you!

Shame that wasn't a Classified card though... I'm also in the same boat as Jay... I also would like to keep my backplate too... But I don't own a dremal...

I guess I'll have to buy it and live with it for better performance. :(
