BrashAchilles Posted October 13, 2013 Share Posted October 13, 2013 I understand that the SPs are for using in places where they exhaust into an obstructed area. The unique flow they create is optimized for working its way around obstructions. HFs are for exhausting (blowing) the maximin amount of air into an unobstructed area. 2 questions. 1. Is the honeycomb design grid on the back the C70 case an " obstructed" area? I'm using an HF 120 to exhaust air out of the case through the honeycomb pattern metal grid and filter on the back of the case. 2 What about pulling air through the same type of metal honeycomb grid and an air filter into the case?. I have an HF 120 on the front of the case blowing air into the case. The flow from this fan is not obstructed, I removed the drive bay. I assume SP and HF designs are the same when drawing air into the fan from an "obstructed area. Link to comment Share on other sites More sharing options...
