Whats the best 120mm case fan for a Fractal Design r4.
Also are the fans in the Fractal Design r4 any good? or should i replace them?
Personally I'd go for some Noctua fans. They're known to have excellent air flow and be extremely quiet.
But they're butt ugly :(
I suppose :(. You can use them where their not visible if you don't have a windowed case.
Good news: Noctua is releasing a new range of case fans which come in more commonly used colours (black and red/blue/green etc) and they will be slighty cheaper too. I read it it one of the forums a week or so ago.
The stock fractal fans are actually pretty good, I wouldn't replace them
If you want cheap quiet fans, go for xion alphawings, I used them for a while and was impressed with how good they were for the price.
Noiseblocker makes quiet fans, but if really want quiet, quality fans you need to look at Noctua. Grey ones are coming out soon if the brown doesn't fancy you.
Noctua fans are great, but personally I would recommend Corsair AF 120. Silent and run your system really cool.
