It's been a very long time since I've posted here, and I'm looking for some feedback on an 80mm fan for my HTPC. Currently I have an Antec NSK2480 case, Scythe Mini Ninja CPU cooler (with Scythe Minebea low speed fan), and 2 120mm Scythe 500RPM Slipstream fans. I've recently had some issues with my TV tuners flaking out, and I believe it may be caused by high codec or tuner temperatures. My computer has not changed configuration in over two years, but if a couple fan changes solve the problem I would be thrilled. My plan is:
Change 500 RPM Slipstreams to 800 RPM Slipstreams
Change 80mm CPU fan from Minebea to either low speed Kama Flex or Kama Flow 2 fan
My question is: which is quieter? Kama Flex or Kama Flow 2? The bearing is a little different, and the Kama Flex has 5 blades as opposed to the 7 blades of the Kama Flow 2. If anyone has experience with these two, I would appreciate your help.
For reference, here are the specs for the 80mm fans:
Minebea 3110KL-04W-B19-EB1 1,400 rpm 17.0 dBA 16.2 CFM
Kama Flex SA0825FDB12SL 1,500 rpm 14.0 dBA 19.0 CFM
Kama Flow 2 SP0825FDB12L 1,400 rpm 14.0 dBA 18.97 CFM
Will there be any difference in noise character, bearing life, etc?
