Dealing with settling dust - Page 2

post #11 of 26
Like others have stated get a Datavac and your dust problems will be blown away. Also invest in a couple of dust filters which can be found here among other sites. http://www.demcifilter.com/c1/Standard-Fan-Filters.aspx

How is you fan configuration and how is the noise level?

I have 2 noctua 120mm in front as intake, 1 noctua 92mm bottom as intake, 1 120mm noctua rear as exhaust, 2 noctua 140mm top as exhaust.
they are very quiet fans. noctua fans are exspensive but they perform fantastic and are very quiet, and depending on which noctua fan model they have a 5 to 7 year warranty
with no receipt required and you don't have to ship them the defective fan you just have to email them a pic of the defective fan next to your id card with a blade broken off after you received the replacement.
I only had 1 noctua fan that was defective, it wouldn't start sometimes on bootup unless I gave it a push with my finger.

You guys think if i put my sp120mm fans as intake it can help?

I tried having them as intake, but i had them mounted in a way that they were pulling the air through the radiator, was getting what I would consider worse temps then them as exhaust. Like I said I have GREAT temps on my GTX 770 with a slight OC and my I7 4770k @ 4.5ghz like this.. the rig is quiet but I hate looking at dust accumulation

and yeah the entire bottom is plugged off aside from the PSU exhaust.

you should try them as pushing intake through the radiator, some say this will put heat in the case but I have yet to see a radiator get hot enough to do that. besides if you have good exhaust then pushing intake through the radiator won't cause more heat in the case.
having the fans pushing case air through the radiator and exhaust out would seem to put case heat through it and not be very efficient, imo.
I have read that using static pressure fans pulling through a radiator or heatsink defeats the purpose of static pressure fans and should be used as pushing air through the radiator or heatsink.

Gonna try that as soon as I have funds for a demci 240mm filter. I also wanna get some solid slot covers and hopefully this will get rid of the issue or at least make it better.

If radiator exhaust is not hotter than it's intake it is not working. Simple as that.

Case air should be no more than a couple degrees warmer than room air.

Static pressure and airflow work together you can't have one without the other. The difference in pressure from intake side to exhaust side of fan is the same with fan in push mode as it is in pull mode..

intake fans should be SP fans so it has enough static pressure to pull air pass the filters. the bottom of the case where you have sealed off should also have a SP fan as intake. if anything your intake fans should be spinning at 1650RPM because it needs the additional pressure to pull air pass the filters. ideally you want to have SP fans on the rad also, but if you don't want to spend more $ then i would move the SP fans from your rad to the front of the case, put the stock exhaust fan from the rear of the case at the bottom where you currently have sealed off and put the AF fans on your rad. reason behind this configuration is you will have 3 intake fans and 2 exhaust fans which would make it a positive pressure configuration. the AF fans on the radiator is less then ideal, however a radiator is less restrictive then a filter (since it's not constantly being blocked up by dust) so it would actually work out better. leave the rear exhaust port open, or seal it off. test it to see which method gives you better temps and go with that.

FYI the fan filters on the Arc Midi R2 are very restrictive. My load temps dropped 8c when I removed the filters. This was back when I was using H220 with AP-15 fans which have substantial static pressure also.

Was that with the stock Fractal Design fans on intakes?

AP-15 is 1850rpm, 58.3cfm, 5.4mm H2O

FD-FAN-SSR2-140 is 1000rpm, 66cfm, 0.84mm H2O

Critical spec is 0.84mm H2O.. not enough to overcome the resistance of filter.

This is a perfect example of OEM case fans not being capable of supplying sufficient airflow.. and why many of us use good cooler fans in our cases. thumb.gif

I never used the stock fans on that case. I individually tested all 4 and each made a ticking sound even at 5v. The AP-15's were set as intake on top, pushing into a 240mm radiator.
