alt Hacker NewsCase fans pull what 4 watts? 5 watts? Who cares if it pulls 200 milliwatts more than a competitor when it's cooling a GPU and CPU that consume more than a hundred times what it can consume
Yes, exactly. The high precision is marketing, not something needed in the product.
My understanding is that the precision is supposed to help with noise. Less turbulence, etc.
FWIW, in my setup (10th gen i5, RTX 5070 Ti in an old Define R3 case), the 12 cm Noctua G2 fans run quieter and have a much less obnoxious noise than the old P/F series, which wipe the floor with the Arctic fan I bought for a computer that lives in the basement and sounds like it's about to take off.
