Tested my new EVGA 1080 FTW Hybrid while overclocking in my room with my ambient room temps at 84-88F & settled on a core at 2101mhz & memory at 5805mhz. Was able to get the core to 2125mhz stable but the memory OC was suffering a big hit though. After 20min of Heaven Benchmark looping my max top core temp was 47C with the room temp at almost 88F!
After turning on my air conditioning I got my room down to about 61-65F (I prefer 63-67F). After another 20min of Heaven Benchmark looping with the same settings my new max top core temp was 35C! During 3DMark benchmarking it did hit a max temp of 37C but that seems to use a little more of the card's power.
While multiboxing 10 World of Warcraft accounts at 2560x1600, I noticed the GPU was at only 50% usage & my core temps were only 30C.
The thing I can not get over is how QUIET this thing is. I can not tell the difference between idle noise and full GPU load noise from the computer at all. Even forcing the GPU fan to 100% from the default 50% or whatever its set to I could not hear the difference(the fan on the card itself which cools the video memory, can't control the radiator fan). I do have like 6 case fans, but I was expecting a low to medium noise difference while the GPU was under load from the radiator fan at least. I had tried a 1080 FE earlier, but at 50-70% fan speed the noise it made was way too loud & annoying for my taste. My Hybrid has no coil whine either, I could not be happier.
The case fan I had to remove to fit my radiator/fan onto the roof of my case I ended up installing outside of my case on the top to "PULL" more air through the radiator making my setup a push/pull config. Ended up using the zipties that came with the card, wish I could link a picture on here but I don't have enough posts I'm pretty sure. I could not be happier with my purchase.
