i used revision fan googles last week for the afternoon at UA, they worked a treat , from memory it was the setting before full I had on but I get hot, had them with fast helmet and half face pro,
on another note, not sure why peope moan about the fan noise though to be honest, these remember are designed for the military who drive in armoured vehicles, jump out of planes, fast rope from choppers, fire real guns, make lots of noise!....., sneaking up on an enemy, the enemy are not gonna say 'oh did you hear that, what?, that buzzing noise (in enemy talk haha)..........they are not supposed to be 'silent' they are supposed to work and do their job
next up, save for some others as really wanted Tan.....there are cheaper alternatives, FMA do a fan goggle but seen mixed reviews about the lens....I went for the revs as they were in stock, sell well, wanted good eye pro so spent the money and wanted to enjoy my games
