      Thanks for that reply Dodgee 
      So for something like a cloudline that I won’t be using a max speed obviously, so would it be recommend to hitch the 500mm for something like that , but as Tom mentioned he changed to a 1000mm which reduced noise due to surface area etc

      The reason for short/long filters is coz historically fans came in 2 varieties for each size. High power/low power    An rvk 150A1 pulls around 480m3h iirc and the 150mm short filter is rated at 500m3h.   An rvk150L1 pulls around 780m3h and the 150mm Long filter (600mm) is rated at 900m3h.   The 1000mm long 150mm filters are really meant for running with 150mm boxfans.   So yeah, an A type fan (low power) is okay with a short filter. An L type fan (high power) needs the longer variant...
