wildhorseau Posted September 9, 2013 Share Posted September 9, 2013 As the title suggests, I am using a H80 with one fan drawing in the case air & the other fan blowing out through the rear of the case. I live in a very dusty area, ( & yes, I do smoke ) & I use a Coolermaster HAF 932, which have quite a few very large fans. The front fan is drawing in outside air, the side panel is doing the same. The top of the case fan is drawing out the warm air. Due to the dusty envoiroment, the case does get a lot of dust & fluff etc, etc. After 6 months of use I had to to strip the case fully & completely clean everything as the all fans were full of fluff & dust, even the H80 was fairly clogged up. To try & limit this, I bought a DEMCI flex filter kit, that has extremely fine mesh. I also bought 2 extra 120mm square filters that I was planning to use somehow with the H80. It seems to be a lost cause "maybe" to use these against the actual fans. But, my question is, would these 120mm square filters work in between the H80 fan & radiator? Or is there a better way to stop dust, fluff etc, etc from clogging up the H80 fans & radiator? I look forward to anyone who may be able to shed some light on this for me, or offer some thoughts.

sinnedone Posted September 9, 2013 Share Posted September 9, 2013 You could do that, but the gains might be minimal as far as trapping dust. Might hurt cooling performance as well. Any pictures of your setup? Link to comment Share on other sites More sharing options...
Specter Posted September 9, 2013 Share Posted September 9, 2013 I placed my H80i on the rear of my Scout 2 exhausting air out in push pull. In the front and top I installed Demci Flex dust filters in front of the fans both top and front as they are all set to intake, my only exhaust is the rear through the H80i. The problem with dust filters is that you will need high static pressure fans in order to pull air through the filter. 200mm fans will not move any air through a filter, you may need 120 or 140 high static pressure fans. I would not place filters directly in front of the H80 as the fans already have a hard time moving air through the fins. the filters needs to be placed as far away from the radiator as possible to allow the fans to move unrestricted air.

wildhorseau Posted September 9, 2013 Author Share Posted September 9, 2013 I greatly appreciate the input guys @sinnedone Might hurt cooling performance as well This is exactly what I am trying to avoid. I have my 2700K O/C'd from default 3.5GHz to 4.6GHz with plenty of room to spare if I wish to go higher. Sorry mate, no pics atm its a gutted case. I will do some pics once it is finished. @Specter I would not place filters directly in front of the H80 as the fans already have a hard time moving air through the fins. the filters needs to be placed as far away from the radiator as possible to allow the fans to move unrestricted air. So you wouldn't reccommend a 120mm filter between the fan & radiator each side then? I may just leave the radiator as it is then. The fans that the Coolermaster HAF ( High Air Flow ) 932 has are: Front fan 230x30 mm 1,700 RPM Side Panel fan 230x30 mm 1,700 RPM (supports 4 120x25mm fans) Top Fan 230x30 mm 1,700 RPM (supports 3 120x25mm fans) The front panel I am setting as an intake The Side Panel I am setting as an intake The Top Fan I am setting as an intake Radiator has default Corsair Fans. Front Intake fan & rear fan an exhaust. To me, somehow that fan set up sounds a bit of over kill as far as intake, with very little, if at all, any exhaust. I warmly welcome any shared oppinions on this, wether they be positive or negative. TIA with respect David Link to comment Share on other sites More sharing options...
peanutz94 Posted September 9, 2013 Share Posted September 9, 2013 So you wouldn't reccommend a 120mm filter between the fan & radiator each side then? No, I wouldn't. Especially if it's something you dont keep an eye on. The filters are restrictive enough without adding trapped dust into the picture. With a radiator you really need to keep as much air moving through the fins as possible. To me, somehow that fan set up sounds a bit of over kill as far as intake, with very little, if at all, any exhaust. I warmly welcome any shared oppinions on this, wether they be positive or negative. Not really. You would be creating what would be a positive pressure inside the case and would help keep out dust in itself. There really would be no need for more exhaust fans.. That much cool air is going to keep your temps in check anyway and help keep dust out. It's a win,win in my book! Nothing says you couldn't try it and see what your results are like. I always recommend experimenting with your fans. What works for someone else might not necessarily work for you. Link to comment Share on other sites More sharing options...
wildhorseau Posted September 9, 2013 Author Share Posted September 9, 2013 @peanutz94 Great info there my friend. I greatly appreciate it I have a air pentrator fan laying around, I might have an experiemnt with & have a bit of a giggle with it. Might mount it on the floor off the case, just for the sake of it. The positive air pressure is what I am shooting for, so it sounds like I have just about nailed it. So the radiator can stay as is, no filters. Just Maybe change the radiator fans.... Sorry Corsair guys lol Cheers Link to comment Share on other sites More sharing options...
wytnyt Posted September 10, 2013 Share Posted September 10, 2013 ive never been a fan of positive airflow myself,while it can help with the dust issue,no amount of ambient air can properly cool the heat hungry components that are constantly producing heat The heat must be removed first so the intake can aid in cooling.. this same principle apples to the pc case and all its components as a whole.try it both ways as i have and see the overall difference in all components another example is using mix match fans on your radiator as one will impede the other and having tons of intake is pointless if that same volume of air isnt being simultaneously pulled out yet another is placing a fan in a window and having all the other windows closed,now open a window in conjunction with the fan... which scenario is more effective?

WesternDreaming Posted September 10, 2013 Share Posted September 10, 2013 uhm , im using bitfenix 80/30 very fine magnetic filters in my haf xb i have them in order outside to inside front cover-fan-filter-case-rad-fan my case has no ability to affect positive or negative pressure from the amount of ventilation it has all of my fans however ( 2x 80mm bottom half, 230mm top, 120mm top half) are all exhausts. my h100 is an intake (4xstock spl's) my case is less dusty on the inside (not saying much) Link to comment Share on other sites More sharing options...
Wam7 Posted September 10, 2013 Share Posted September 10, 2013 If you want to decrease the dust build up in the radiator then you might want to use the fans in a pull configuration. I remember seeing one of Linus' video where he shows the difference in the amount of dust between the push/pull. He also states that the cooling for either config is about the same.

I disagree as Linus is not always right. A push pull can be installed on the radiator, just make sure all instake fans have dust filters and the only exahust is through the radiator. Works for me.
