Including the one in the PSU then 8 of them, 2 of them on the GFX card which are air cooled ATM
From now on i am only dealing in 140 mm fans or larger, new project have four 140 mm intake fans, and thats probably going to be it.
To make it easy for myself, i have put all 4 into one large quad unit.
This mean with the planned RPM and the performance of these fans, the volume of air in my living room will be pushed thru my PC case 4 times every hour.
And i am not running these suckers at full tilt, if i did it would be 40& more air / hour ( assuming RPM / volume of air moved scale 1:1,,,,, which i know it dont )
