    Fan Setup for Best Airflow???

    How does everyone set their fans up for the best maximum airflow?

    Here is my computer case:
    Newegg.com - Rosewill R6426-P BK ATX Mid Tower Computer Case - Computer Cases

    Here is my CPU cooler:
    Newegg.com - ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler - CPU Fans & Heatsinks

    I changed the stock fan that came with the case for a better 80mm fan, which is blowing inwards towards my cpu fan. I have the CPU fan turned so that the back fan is blowing into the back of the fan on the heatsink, so all airflow is coming from the back, through the heatsink towards the front of the case. I had to remove the duct from the side of the tower because the CPU cooler is so freakin' tall it is literally a 1.25" from the wall. So placing a fan in the duct's place is also pretty hard. The other available spot on the side panel also has an 80mm, which i'll upgrade to a 120mm fan. This fan blows inward towards my HUGE video card to try and keep that cool. I also removed all of the front aluminum panels (the ones which are removable when you place in a cd/dvd rom, which helps the air from the back to be blown through the front. Since the cd/dvd rom covers on the case are perforated, air blows through them nicely.

    Anyone have any suggestions for me that will help my airflow with this case?

    I need more rep for this lol.

    Airflow should be front to back. Intake should be one fan at the front and one intake on the side. This allows for one fan at the rear of the case extracting the air along with the fan of your power supply. This makes for 2 intake and 2 outake.

    By using this config your pushing cold air in at the lower part of the case and extracting it at the top of the case. The way you have it just now your pushing the hot air of the cpu over your northbridge and ram which isnt a good idea. You should also put back in the aliminium bezels.

    great post.......

    this is EXACTLY what i would of suggested...

    personally i try & aim for a ''positive'' pressure in the case rather than ''negative'' (more fans in than out)
    this will ensure air is not being dragged in where you do not want it to be....i.e cracks, drive bays, IO ports....you'd be amazed where dust builds up in a ''negative'' environment...

    the side panel fan IS A MUST if possible... air blowing directly on your RAM DIMMs & mobo keeps those temps nice & low....

    Thx gentlemen for your help once again. I've looked at that website you linked in another post for me Stew. Thanks! I'll probably be going there for another new case.

    OK cool, lian li cases are by far the best cases for the money. Also try some cable management in your new case as this can help to keep temps down as well.

    "more fans in than out" i follow that as well. With lian li cases there will be air filters, if you ensure you have a positive pressure within the case you should only have to clean the filters and not the inside of the case.

    I've already found a couple of cases I like on Newegg:
    Newegg.com - LIAN LI PC-7FW Black Aluminum ATX Mid Tower Computer Case - Computer Cases
    Newegg.com - LIAN LI PC-7BYCF Black Aluminum ATX Mid Tower Computer Case - Computer Cases

    I like the second one, mainly for the clear side and large fan. Just worried it won't fit with the height of my Newegg.com - ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler - CPU Fans & Heatsinks.

    I'll probably order either case when I get another 4G's of ram.

    But when I get home, I'll switch some fans around so that the back fan is pushing air out.

    if you go for a new case try to get the Cooler Master 932 HAF case if it is in your budget
    if not go with NZXT or thermaltake

    I like the Cooler Master 932 case too! That's not a bad price either. Hmmm... decisions... decisions...

    Edit: Just saw you aren't using it, nvm. :-/

    well i know it is a good case..... was just outta stock when i ordered
    but xgunthercx,smartyeyeball, and many others have that case and love it
    and from all i have read it is a very reliable case
    also the NZXT tempest is really good everything expect my gpu is a 25 c or lower the gpu is at 49 c because of the fan only running at 30% on it
    my cpu idles at 15 c

    My gpu runs in the 50's. If I remember correctly, Nvidia's monitoring software was showing me that my gfx card fan was running at 30%. I'm probably just being dumb, but I think that is what I remember. Can anything bad come of me pushing that fan up to 80% or so other than it being louder? I can deal with the possible noise, I just want to cool my vid card down. It gets pretty toasty in there.

    Edit: I was using HWMonitor when I was overclocking and running my stability test. How do I know what my temperature is when I'm idle? What constitutes a system being idle?
