i am wanting to add 2 fans behind the CPU in my MDD i have a 60mm fan but i only have one and it does not move much air.

I know that 70mm fans will fit here as well squeeze fit but it will fit.

I also want to add Two 50mm rear fans (below the PSU) to draw air out off the HDDs. I also want to install two 50 or 60mm fans in the front for air intake.

what i am looking for is fans that will move the most air at the quietest noise. Problem is i have no clue how loud a fan is by the dBs of the fan ive heard the giant fan in the MDD is some 60 dBs? That is WAY too loud. SO i was thinking fans in the 30-35db range i found this fan it is 25dBA and moves 31CFM is this a decent amount of airflow?

can someone point me in the direction of the best 50mm fans?
