Inno3D have been around for a long time. I heard about Zotac way more recently than Inno3D. Main thing with Zotac is the length of warranty if you register it with them. I've got a Zotac 1080Ti and it's dead quiet - although I run a custom fan curve dependant on temperature.
TBH most modern GPUs are quiet - especially if you set a custom fan curve.
Regardless of which card you went for, you've got a great deal. None of the ones on offer were a 'blower' style, which tend to be noisier. I was tempted myself, but the performance increase from a 1080Ti wasn't worth the upgrade given what I play.
