How do I test for this to see if my 1080 FTWs have this issue?
 
I run Precision XOC and monitor my fan speed percentage. I run an aggressive curve and I've never seen any spikes.

look at the fan tachometer portion of the graph, or have your rpm show up in the osd, look for spikes there, i have consistent fan speed percentage, but my rpm spikes from 1K to #K alot for no reason like many people with this problem

Thanks, I didn't realized the OSD had the tachometer until you mentioned it. I monitored it while playing BF1 and my RPMs do not spike at all. Whew...

Just to be sure, you might want to test some other games with it. If you have the witcher 3 i would recommend using that as it certainly makes the issue apparent. My 1080 does not see nearly as much load in BF1 as it does in TW3

I have the same issues. My fan is constantly going up and down - the sound is terribly annoying. I also have these huge spikes that show up in EVGA XOC monitoring - up to 6k, which can´t be.
I am not exchanging the card for now, but the sound is so terribly annoying....

Having the same revving issue and not sending the card back since 99% of all replacements have the same issue. Hoping a BIOS update will resolve it. I traded in a perfect 980 Ti Classy for this :/ Really disappointing. Precision makes the issue worse, keep that in mind guys ;)

Same here, I trade in my perfectly working Classy 980Ti for it. I am disappointed on 2 levels - the terrible build quality of the 1080: this card has so many issues I never had with any previous card. Revving Fans, using PXOC is impossible because it makes it A LOT worse. Then the damn limited supply....it took me months to get the cards because it basically sold out everywhere all the time. And the icing on the cake being the fact that it is a lousy 6% faster than my classy @ 1580mhz was. Should have kept the classy....

Just got my advance rma for my 1080 SC......still has the revving issue. i dont even feel like its worth sending for another. 

I installed a waterblock....at least the damn fans won´t annoy me any longer. But this is a huge issue and I find the lack of information from EVGA concerning. This and the overheating VRMs....

Seems I'm having the same issues on mine as well. I didn't even notice it until I installed the vBios update for the VRM overheating issue, which seems to have made the issue much worse. I thought it was the vBios update that caused the issue in the first place because before the card was really quiet and now it sounds like a vacuum cleaner when under load. I bought mine from Newegg around 3 weeks ago.
