Not 100% silent, but lots of new projectors are based on LED/laser lamps, which produce a lot less waste heat.
Plus there's now ultra-short-throw projectors that sit in the front of the room, rather than above / behind you.
Ultra-short-throw also has the advantage that you can use from-below lenticular screens. This means that ambient room light affects them a lot less, since they refelect light mostly coming from only where the projector is.
Sadly, "smart TV" has infected projectors as well. But maybe not as bad as normal TVs. Most projectors still have dumb inputs that work fine.
