(I got my idea from this THREAD
I noticed that my disk temps were running a stready 42C, and although that is not extremely high, I wanted to find an easy way to keep this thing a bit cooler.
First, I gently removed the screen behind the grill (held in place with sticky tape). Although it only increased airflow a little, it really helped cut down on the rushing air noise. My average temps fell by maybe 1-2 degrees C. This will allow bigger dust particles into the box, but it is already in a dust filtered equipment closet so I am not to concerned.
Next, I noticed that the front 92mm fan was not very well lined up with the grill openings. In fact, it sort of looked like they had originally planned to put a 120mm fan in there. So I thought, hmm, sounds like a good Sunday evening project.
I bought this very quiet fan at C*mpUSA for <$10. Quite a bit bigger than the stock fan. 60CFM @ 24 dB, perfect!
Step 1, remove ugly sticker!
Then I removed the stock fan and it's mounting brackets and what do you know, the 120mm fan fits like a glove! (OJ's glove being the exception of course)
Next I found some old plastic pieces laying around my workshop (note the built-in standoffs), and I trimmed them to size with a sharp box cutter.
I was able to re-use the original screws, but this time I inserted them from behind (insert your own joke here), into the standoffs. Fit perfectly. I also used a countersink bit to drill the holes in the front of the plastic pieces.
The best part of this mod is that no holes were drilled, and no metal was cut! Can you say; "Warranty Intact!" If I ever have to send it anywhere, it is very easy to reinstall the original fan and brackets!
Even though I did no drilling or cutting, if you do this mod, be sure to give it a few big blasts of air to ensure no crud is left inside the box.
The final product
You can see from the photo how perfectly the 120mm fan lines up with the grill now.
FWIW (in case you were wondering), the electrical tape on the front is to help dim the light emitted from the LEDs, they are far to bright (in my girlfriend's opinion).
I will let the box run for a few hours before I post any info on temperatures post-mod. Frontview is showing everything A-OK at this point, with a current fan speed of 1049 RPM.
One final item, since I could clearly see the annoying white plastic and the screws through the front grill, a good coating from a permanent black sharpie and the problem was solved.
This might be *ahem* a good idea *ahem* for Infrant to use *ahem* for Revision C.
