After a fan controller that will fit inside a Silverstone SG-03 case, and allow the hinged flap to close.
Was looking at an Akasa AK-FC-06SL as it has the advantage of no LED that wouldn't be seen.
Also consider the Scythe Kaze Master as an alternative. But the display feature seems wasted, and not sure if the dials are too tall.
Anyone able to recommend one that fits and still allows flap to close?
