    Good day to all,

    I am posting this thread so that everyday people can use their existing equipment and further improve cooling. Not all of use opt for water cooling solutions. Condensation has become my enemy: R.I.P. ATI X850 Pro 256Mb - moving along!

    Simply put, unless your case has 3 fans or less, this article is not for you. Fans need to be positioned: front, rear, side panel for bare minimum cooling. Many things influence cooling: CFM's, room temperature, case, if your cat(s)/dog(s) shed alot, cleaning, cabling, graphics card,... this article cannot keep all that in mind at all times. My room sits steady at 27-29 degrees (space heater) everyday but my buddy has his at 21 degrees. We are here to discuss the implications of what a fan position versus another increases cooling. Examples are best. Pictures work too!

    I'd like to begin this thread by a few problems I have encountered. I noticed that case temperatures can be warm like a summer day but my case has so many fans that it is cooler than my room temperatures (~27 degrees). Without aimlessly changing the position of my fans in my case with trial and error techniques, i'd like to see what your thoughts are on this: Should I make the fans in my case blow the air out of my case instead of bringing warm room temperatures inwards? My idea is if I make the air go outwards, it would create a "funnel effect". But lets not be stupid here, warm air will most likely change into cold air by blowing air inwards in the case. BUT, in the long term, wouldn't that create heat zones in my case in certain areas (below my GTX 260, between HDD and DVD drive,...) and these create heat build-ups.

    This post is long-winded as it is. Please let me know what your thoughts are. Check my profile for specs. Have a good day! Tech nerds unite! :)

    I find it better to have average air input and high air output as this is more likly to remove air from hot spots. All though the case needs to be sealed well to make it work really good.

    what can happen by doing this is to course dust to show up around bay drive edges so make sure those areas are sealed up good too.

    Look up. Look way up.
    I agree just make sure you have the exhausts on the upper parts and the intakes on the lower chassis areas (cool air falls, warm air rises.) having one more exhaust than intake is always good. It's all about airflow :pimp:
