If its 60c with reference cooler, even if its with fans at 100% which i seriously doubt, it bodes well, can drop the fans lower fir a bit more heat!
On a serious note, that 3 fan reference cooler looks more than capable of keeping the card cool and quiet, it's as decent looking as a lot of Partner cooling systems.
I think AMD are starting to polish their GPU launches a step at a time, quite like they did with Ryzen CPUs.
One thing we always derided them for was their awful blower coolers, looks like this could be them saying "Hey, we listened"
Seems the performance in Rasterization is there, and their first attempt at Ray Tracing looks to be ok, lastly their rumored FidelityFX Supersampling (DLSS) is in the works as well.
Looks to me like they ticked the box of most arguments actually, so i seriously doubt they are going to change cooler design and it be a fail.
I reckon the reference cooler will be as good a cooler as your average 2.5 slot 3 fan gpu cooler.
60c at a reasonable fan speed with relatively low noise.
