NZXT H440: Which Fan Replacements?

[AfxTwn]

Hi, I have a 2 year old NZXT H440 case and the front fans are starting to go (making whirring noises when first spinning up) and so I am looking for suggestions about replacing them and possibly all the fans in the case.

I have a Asus H81 Gamer motherboard, Intel i7 4790K (not overclocked), 16GB Corsair Vengeance Pro Red DDR 3 Ram (2 x 8GB sticks), XFX Radeon R9 290X BDED GPU and a Cooler Master G750M PSU.

I don't have an water cooling or all-in-one radiator, just the standard fans that came with the peripherals and the case. I'm not bothered about overclocking, just in trying to keepp dust out of my case and it reasonably cool and quiet.

I'd appreciate any suggestions.

Thanks very much.

You cant overclock anything with H81 motherboard anyway.
I would get the cheap Cooler Master Hyper 212 EVO though, it's more quiet and better performance then stock cooler. Mounted with fan towards RAM slots.

Quiet case fans, need three of those, two in front to replace three 120mm there and one in back to replace 140mm there:
