Found a great deal on some quiet fans at NCIX , so I jumped on it and ordered a bunch.
I’ve ordered four Vantec Stealth can fans (80mm 2050rpm 20dBA 27cfm dual ball bearing) and one Papst fan (80mm 1500rpm 12dBA 19.4cfm sintec sleeve bearing).
From the AVSForum, I know that one person has replaced all 3 of his fans with the Vantec fans and hasn’t reported any serious problems. My plan is to replace the power supply fan first with the Papst and see if the temperature is ok. For the two other fans, I’ll use the Vantec.
I’m also considering adding a fan to the HVPS, but I’m not sure if one of the Vantec’s will fit, or if I need a different fan. HVPS maintenance is on my list of to do items.
