Yeah it is, I just hope I get lucky haha, I'm fine with 2 fans, never had a 3 fan anyways.Coil whine is not something that manufactures have much control over from my experience, it just seems to be a possibility with high power mass produced electronics. So that will be down to luck no mater what board partner you go with.
Is this the dual fan Palit you ordered?
Palit are fine, they use cheaper parts than some others but it's within Nvidia spec and will not cause any issues.
The only real downside with that card is the dual fan cards will be louder than the larger 3 fan options available. The 3060ti is 50 - 60 more watts compared to the 1070 so more heat and may be a little louder than what you have right now.
Fan noise isn't as annoying imo and the fans are usually auto off, the coilwhine only happens on high end games and is awful. Heat wise, my pc is usually on the hotter side but I'm fine with that - especially because my room is almost always freezing.
