Just took off loud Volcano 9 that i had running at 3100rpm, and sat at 37idle/42load...and replaced it with a the aeroflow i picked up this weekend...Quieter then the V9, and now, i'm sittin at 28C, idle...havent stressed it yet...will check though...But anyway, so far i'm impressed..and looks sleek compared to that big orange fan i used to have....Now to just get some Stealths to replace 5 loud antec case fans i have...this thing should purr.......
