Stop jacking your post counts. its almost like a circle jerk..
On a more serious note, you maybe having trouble because of dead air spots. You have more blowing in probably than is being sucked out. A fan blowing on the wrong spot can cause a spot inside the case where air doesnt flow, and the air pressures from the fans keep the dead warm air in its spot circulating the same warm air. This typically happens behind a heatsink if you have a vertical one.
+1 on circle jerks. +1 for right angle creeps jerking their post. Any single case fan you install anywhere in your case would at most make 2-3c difference. Possibly slighlyt more if no case fans were installed prior or the case suffered from horrible, non existent air flow.
+1 on cable management, i know i dont do the best jobs on cable management (you only have to check this thread here http://www.tomshardware.com/forum/253025-28-good-cable-management-pics ) but i do a better job than alot of others. And if you have a bunch of cables effectively walling off the inside of your case the airflow is going to be terrible.
Most definately no question the newer style cases with the 'mesh' front bezel like the CM 690, Antec 900, Antec 300 etc. (a lot more I fail to mention) help with airflow and system temps tremendously. yeah, I'm trying to imporve my cable management over the years. But, yes I agree, these are all important ways to have lower system temps. Amazing what a well placed, good quality 120mm fan will do in place of a wimpy 80mm. I keep the 80mm to 120mm fan adapters on hand. Have for years now.
+1 to chookman for being rersponsible for the blue color of our sky. Ha, I've got you mixed up with the color spectrum and the distance the earth is from our light source, the sun. Want me to explain why the Mars sky is red? Al this and any further explanation may effect our post count positively speaking.
I have a Raidmax Smilodon case that has 4 fans total. One 120mm on the back, one 120mm on the front, and 2 80mm on the side. How should I configure these to get the best possible airflow?
the smilodon has room for a 5th fan... on the mobo side there is a cage for a 80mm fan. what i suggest is that you take the 80mm fan from the side bar and put it over to the hdd side and then get this thermaltake fan.
this fan pushes an amazing amount of air. also... if you are really serious about the airflow. i don't think the rear 120mm fan on the raidmax is sufficient i don't feel any significant or any amount of air coming out the back from that fan. so i'd suggest you change that too if you really want to keep ur system cool. i'd suggest the scythe fan.
btw i have this case. and the fan i suggested to you.
