I'm by no means a professional, but I experiment a lot with different cases, and airflow, and different fans from different manufacturers.
When you have fans as intakes in the 5.25" bays they tend to squirt some air up towards the top exhaust.
Please take a look at the video at the bottom of this link to see what I mean in regards to airflow of the majority of fans on the market.
They tend to shoot it out towards the sideshttp://www.silverstonetek.com/tech/wh10_0061.php?area=usa
If you take a look at this link below, please take note of point # 6
You will notice that in the case of the HAF - X you have 3 fans all fighting to suck air out of the case.http://www.silverstonetek.com/tech/wh_airflow.php?area=usa
Essentially starving each other raising temperatures from lack of air intake. (goes back to the principles of negative & positive air pressure in the case)
I mucked around with my own HAF X a bit. I ended up swapping out all the original fans and replaced the 200mm x 3 with the CM Megaflows in blue (original stock fan in the top was defective, and I like the colour more
) along with the front 230mm with a 200mm CM Megaflow.
I turned the front top fan into an intake, and I also have a 140mm air penetrator pushing the air that is being taken in from the 5.25" bay, directing it at my cpu heatsink (fresh cool air drawn in from both top, & the front mesh panels)
Also have a 120mm blowing over my video cards towards the rear, and out the grilles there.
I also replaced the rear fan with a noctua 140mm fan to move more air.
Dropped my temps quite a few degrees, went from 36 degrees on idle to 27 degrees.
I could alternatively flip the rear 200mm top exhaust fan to intake as well, however I looked at the way air was flowing towards the rear fan, while it ideally is forced through the rear chassis exhaust, I noticed some air circling between the top corner around the top 200mm fan. (I used some dry ice & water to pump some mist into the case to test:D)
Anyhow, I just left that fan as an exhaust, to eliminate that dead spot.
Now airflows from the front to back in a relatively smooth manner.
Experiment around with your case, and see what setup you like.
Hopefully you're able to get things to work out nicely.Edited by Xinc - 2/15/11 at 10:15pm
