Hi.
I have just finished with my mini itx build using the corsair 250d case.
My only problem at the moment is the noise, i have 2 120mm corsair fans on the side and the stock fans on my h80i. I was recommend to replace the fans with noctuas.
If it was to replace my fans, which noctuas would i use on my h80i and which for the side fans?
