A simple rule of thumb for calculating cooling flow requirements is:
CFM = 3.16 x watts/allowed temperature rise (°F)
This calculation only represents required airflow, not the fan rating. It is a conservative number because there always is some radiated cooling and turbulent flow within the chassis that can help remove heat from components. In a well-designed chassis, one can count on getting only 40-50% of the free airflow rating for a fan. Thus, a 300W system with a 20°F temperature rise would need about 47 CFM through the chassis or a fan with a free air rating of 100 CFM.
ok if security is needed then cabinet's are a good way to go .. lockable and
able to be in the open ... a hydrohut is not good for that.
take care man

:stoned:blue_ox Reviewed by blue_ox on . joe-grow's first grow Long time reader, first time poster. Long time smoker, first time grower. So, I've finally decided to take the plunge into growing. I spent the last month just reading up on the postings here, as well as some magazines I picked up at a local hydro store. This board was the most helpful, and I hope to repay that help with a grow report which I hope helps at least one other person out. During this time, I'm sure I will ask for assistance from some of you out there, and I hope that I am Rating: 5
