Hi all, I own a cm690 casing with 4 120mm fan. 1 inlet at the front and 1 at the side panel. Exhaust is at the top& back panel of the casing. It has been less than a month but my casing is already covered in dust inside and outside. What can I do to reduce the dust and how can I clean them from my mobo ?

put dust fill the for intake fan...

Install the dust filter for the side cover fan (the front fan is already having a filter).

CM 690 is good for airflow, but it also attract dust. It is quite norm ...
Try to clean your case once every month (which I am doing right now).

Renovate ur house with clean room facilities.

with this ur mom wont call u to do house chores

there's no effective way to reduce the dust effectively i'm afraid.

all u can do is to clean it regularly. the fastest way is by blowing it. don't use vacuum when ur cleaning the mobo, gc or any electrical/electronic parts as static might damage the components (diodes, chips etc).

i'm oso using the same casing, 7 90cfm fans inside running. with or without the filter in a week or 2, a thin layer of dust is alr visible inside.

Find a thin sponge to cover the top just like the ones provided for the front cover. Then use a filter or DIY filter (pantyhose) for all the fans.

or change ur casing into negative airflow set up (more hot air goes out,less cool air go in).

currently oni my front 12cm fan is blow in,others are all exhaust,so i oni need to clean the front regularly

I disagree. should make it positive airflow n put some intake filters on the fans. this should minimize the dust

Thanks all for your advice.

Hmm how do u clean it ? Dismantle everything and wash it with water ? How about the dust on the mobo and GPU ?

Hmm yea less than a month i can already see dust. By blowing it you mean using a hairdryer ?

Where can i buy filters in Penang ? Oooh the pantyhose idea is good ! I'll give it a try if i cant find the filters.

hairdryer?

no la, dunno how to say the thing, i'm using it to blow the dust out ( the one u squeeze2, blower?)

u can get it at any pc shop, cheap too. and don't forget to get a brush, either a hard or soft type. perfect for fans, mobo and gc.

it didn't minimize the dust,it just minimize the dust to be seen by ur eyes frm the outside,once in a while u still need to wash ur filter

and filter will lower ur fan's airflow as well (cfm),although not so obvious but the effect is still thr

here's how it looks like when i clean up mine for the 1st time a year ago...

it's only after a month of usage. 2 stock 120mm as intake, front and side, 1 at rear.

now i'm running it 7 fans total, all CM's 90cfm fans, 3 intake, 3 exhaust. a total dust magnet

mine not so worse,at least frm the inside.but the front panel after 2 weeks or so can start see-ing it turning frm black into gray.

running 6 fans in total (if count hsf fan).oni the front 12cm and hsf is intake,others all exhaust.

i knew this would happen when choosing casing with lots of holes at front, side and top. so i clean it everyday

clean ur room....and put ur casing higher than ur floor...
mine..intake fan's front + bottom....upper fans + behind is exhaust...
side? i put customize fan grille i mean..no fan at the side

@Sib

Hahaha, urs look like it came out from the desert.

@TS

Im running 2 front intake, 1 rear, 3 high cfm exhaust at top, and 1 rear exhaust. At front there's already sponge lyr so no need to worry, the side is kinda bad.
At the bottom, place a thin sponge/filter for ur psu, its one of the weak points of CM690, its gonna kill ur psu long term if u leave it naked.
My bottom got no fan, just a filter cuz got no space, too cramp with my pump. .
Dust will always be there unless ur in a 'dust free room' of course, u'll have to clean the surroundings too.
Get urself the Cyber Clean stuff, its very easy to clean anything, fans, intakes n filters, dun use it on ur electrics though.
I've just cleaned my pc after 6-7 mths, and it wasnt that bad cuz i clean my room often. The dust layer collected was just like a house thats not been cleaned for 2 weeks. (thats my house la, others i dunno)

not bad ma. no need clean room. clean casing can already.

if too many dust entered casing,can it damage the other component like gc,ram n psu?

like the psu and gc where cooling is really important, if the dust cover the fans/heatsink . . . means less airflow, means more heat buildup then ends up with damages to components. For rams, not really, unless u oc them wit high volt, which requires colling too.
