Asus Prime 5080 OC vs Inno3D 5080 X3 OC

Benchmark/Thermal Test

Some time ago I was a bit nervous about Inno3D 5080 idle behavior. Everytime it reached 50C, the fans spin up in an unpleasant way. This black Friday I did an impulse buy and got a prime 5080. No such issue, card hovers at 51C and does not spin up fans on idle.. and if it did, it would be inaudible...14W idle power. Gaming temp is a bit misleading because it depends on wattage, but furmark@340W yields 68C. Needless to say, Inno3D is both hotter and louder, and has high idle power. I am impressed with the Prime, really good choice for ie a T1 build.
