user12920: This thing sounds like there is a jet waiting to take off in my office. 
Can I replace the fans with quieter ones? If so, can you recommend which fans to buy to replace the stock ones?
Thanks!!

user2306: You're looking for a 120mm x 120mm x 38mm fan which can produce at least 120 CFM of airflow and runs on DC 12V. (Source.)
According to a random guy on the internet, the stock fans produce about 60-70dB of noise.
There are various fans you can buy, but they're all pretty similar in terms of noise.

You can also buy one that has less airflow, but is much quieter.

...or, if you've ever looked at your Hurricane and decided you wanted twice as much airflow, you could install this:

(The product reviews even use the phrase "jet engine.")

This will void your warranty. (Assuming you have one.)
