But really, there's not much solutions.

Water cooled loop would work, my Evga 3090 ftw ultra with max graphic settings on a g9 5120x1440 240hz monitor maxes out at 43c with this game, Valheim runs about 5c hotter than 90% of my games.
With the 1060 I would not advise you spending your money on a water block, do what Jonnin suggests and I always find setting a fixed fan when gaming is better than a curve.
