So I have a n400 case its pretty nice, not counting the fact it doesnt have much space for cable management, but to the real question. My stock front fan was making some strange noise which i didnt like, it was defected, but i thought that for some cheap fan its not worth to take out all the system and send out the case back to replace the fan, so i just took it out. and now like after like half of year of taking it out case has quite alot of dust so could you help with what should i do? i could pick the case fan from the back and slap it in the front but would that be a good idea? also i could just buy some cheap deepcool fans but 1 it may be making alot of noise because they are very cheap ( the case fan on the back is quite queit i got to say) 2 would it be worth it as right now im saving for a new phone xD help meh guys
