Cheers TAZOO7 I'm currently using the stock fans on my swiftech h320 and not sure how good they are I do however have 3 of the below fans if they are any better? I'm not an extreme overclocker I'm just a noob at watercooling and want a good look as I'm going to change the hose to white

They are case fans mate and are not suitable for rads or restricted places, you need Static Pressure fans like these Noctuas now i have not tried them all but found these to be much better than the Corsair SP120 fans, they much quieter and do a good job of cooling, a lot depends on the radiator to, more FPI then the more RPM's you tend to need, lower FPI then you can get away with slower fans with lower SP, best bet it to start a new thread in the water cooling section and get better advice, stock fan are ok but the tend to be loud, but they do the job
