I have an hhc-001 over my duron on my pc at work. I am upgrading the machine and putting an NF7-S and a 1700 dlt3c in it. I ordered an SK-7 for it and now I need a good 80mm fan. I want as much air as I can get without being louder than the HHC-001 . Will a delta 38 be much louder ? That high rpm 60 on the hhc is pretty loud.
