Can you fellows give me some recommendations on 12v 120mm or 140mm fans to be used at the end of a long run of 8 inch HVAC ducting? The ducting will be running from the top of an enclosed home theater equipment cabinet and I will install multiple fans at the end of the run to pull hot air out of the cabinet. The fans will be mounted in a custom box to which the ducting will be attached.
Of course quieter is better but noise level is probably not as important in this application as is CFM and fan lifespan. Given the application the fans will be used in, what fans would you recommend for the job?
What's your budget? These TY 140's from Thermalright are fantastic for the price, they surpass Noctua's and mount into 120mm brackets. $15http://www.frozencpu.com/products/11677 ... Mount.html
You could also go with Gentle Typhoons or Noiseblockers, though you may be able to get away with louder/higher CFM fans because your duct will be far from the HTPC right?
