Thinking of canceling my FTW order tomorrow and just getting an FE card. Asking in here as id like too know how you guys are getting on with temps and also has the fan revving issue been sorted out ? thanks sam
The fan issue is fixed with the latest driver.
Temps will normally reach 83C (the default Nvidia limit) if you're running a game that pushes the card and you're also using the default fan profile - obviously it depends on room temperature and case setup but for me the fan normally reaches 50 - 55% in these situations.
It's worth pointing out though that the fan on a reference 1080 running at 60% is still quieter than the reference 980ti fan at 50%, so the fan is quieter in general - I would guess that the 1080 fan has to reach 65 - 70% in order to match the volume of the 980ti fan at 50 - 55%!
Overclocking is a bit more tricky than the 980ti I've found as the card seems more likely to throttle and downclock, plus since it tends to boost to around 1800mhz anyway that only really leaves you 200mhz worth of headroom before most 1080's seem to be hitting their limits. So you add the 200mhz in afterburner but unless you keep the fan speed up (above 65% for me) you'll rarely keep the 2000mhz boost for a sustained period of time. I should say this is just my experience and obviously some people will be more lucky. I have a good case though (FT05) and it has ninja cable management.
Looking at a game framerate I used the Witcher 3. With everything maxed out at 4k and hair works turned OFF my 980ti's in SLI running at 1380mhz would average between 55 - 60fps but this was pushing the cards hard with 100% usage. The 1080's in SLI running at stock clocks are averaging 70 - 80fps (with the same game settings of course). This means there is the option of turning hair works on (I hate how that setting has become such a 'thing') or just turning vsync on and suddenly the cards aren't been pushed to their limits (80 - 85% usage) and the system is nearly silent.
Overall I'm happy with the 1080 cards, especially the quieter fan, but I feel like there isn't much room to boost framerates with overclocking compared to the reference 980ti - I feel like adding 200mhz to the 980ti's showed a bigger framerate gain relative to what I'm seeing with the 1080's.
