Well I would really like silence. I'm currently looking for a big copper scuba or gas cylinder like tank to use as a reserator. Then the only noise will be my pump. But I'll probably have to use an actively cooled heatercore at least for a little while.Edward Ng wrote: But would this be in any way quieter than using a standard 120mm fan in a pull configuration? Or are you going for higher negative pressure, rather than silence?
Like I said before, I plan on getting Papst 4412 axials right now and running them less than or equal to 7V based on chylld's recommendation here at SPCR and a few other guys on different forums. I thought about using the Nexus 120mm "Real Silent" axial fans but someone here recently said the 4412s were just a little quieter than the Nexuses at the same CFM, at least in open air, nonrestrictive testing.
You should be able to obtain the same dBA as an axial and have better airflow though the heatercore with a blower as the blower design is inherently better in a high restrictive environment. But I don't know if such a blower exists in the market. An axial fan only has a good bit of sucking capability when the RPMs are high so a 120mm slow turning axial isn't that great of a choice for a heatercore. My hope is you can get a Sunon MagLev 120mm blower to quiet down to the same level as a Globe, Nexus, or Papst or at least to Panaflo levels. As far a the Camry blower, I believe the issue would be the undervoltability of the motor and how loud the motor would be. Even if the Camry blower blades made more noise then a Globe, Nexus, or Papst, the sound would different and more acceptable. Whitenoise I believe it's called. I don't mind the low frequency noise near as much as the high frequency spooling up jet turbine type sound.
Sort of. I also use heatphones for gaming so I don't mind a machine that's more on the quiet side than on the silent side when gaming. But I would like to be able to quiet everything (via fan controllers and such) for non-gaming use.Edward Ng wrote: Or perhaps you're going for some sort of in-between balance (not dead silent, but not loud, yet still moving plenty of air)? Such as my own water cooling rig, which is a gaming rig used with headphones, so I set a looser noise level constraint for that build, allowing me better flow rates for the massive overclock.
So if I'm not able to go with the homemade (and much more capable) reseratior route, I'll have four case fans. 1 PSU (Super Tornado or something), 1 Rear Case Fan Out, 2 Front Heatercore In (Fan Controller controled). Probably slightly positive pressure.
