Fan controller???

[MG44]

I have 3 case fans on my pc, 2 120mm at the front and rear.
and 1 90mm fan on the side
currently i am using a special fan cable that uses the PWM connector on the mother board to controll them, obvilously as the cpu is used more they speed up to cool it.

How ever the side fan is rather noisy even though it is a quiet design.
My options are to place a switch on it to enable only during gaming when i only really need it

or

get a fan controller to control all of the fans manualy.

Which seems the best option??

temps are ideling around 35 for the cores
its a red wing fan which i got cz it low noise, the noise is from the fan filter which i have to have cz my uni room is so dusty my case fills up with dust in a few weeks.
Having spent the money on a fan dnt wnt 2 just ditch it and dnt wnt a large ugly hole in the side of my case

iv un plugged my side fan and have seen no increase in temperature so for general work it seems it isnt really needed much.
Think that having the 2 case fans controled by the PWM is very good as they r going at low speed in normal use.

Will just solder a nice looking switch for my side fan

Right now need to look for a PSU unit so off to the other forums, thanks guys
