i clean my pc every week but then also there is lot dust i use rubber bulb blower
What is price for normal 120mm fan ?
and for Vantec fan/Antec
The trick in not having dust in the case is to keep playing musical chairs with the hardware.... I change my drives and fans like you change clothes

To get dust out of a case the try using a cloth instead of a blower - a blower will just move the dust from one place to another inside the case itself. I use the yellow cloth used for cleaning cars. I clean the fans with a stiff brush and a with a rubber blower outside the case. My HDDs pick up a lot of dust and I have to clean them every week - I have the HDDs sandwiched between 2 120mm fans - keeps them cool but dusty

I have seen cheap Sunon (fakes ?) and unknown branded fans for around 350/- ... I would never buy these fans as they will not be very good. Vantecs UVLED fans sell for around 650/- and Antecs are more than that maybe around 1200/- (not sure) check at theitdepot's pages for Antec fan prices.
