zalman multi connector 1 and papst 8412 N/2GL

14th February 2004, 14:36

Can the Zalman multi connector 1 and the 80 mm case fans of papst type 8412 N/2GL be used on the 5 v - mode (silent mode)?

On the specifications it is mentioned that fans having a start up voltage of more than 5 V can not be used. The fans are 12V .

Has anyone experience with putting papst fans at 5 V.

Hmmm... i have two of those papst fans on my rheobus. At ~5V one of them sometimes won't start. I think you'd be safer running them at 7V.

The multi connector only allows 5 or 12 V, I must say they make the most noise in my system when i don't use any 80 mm case fans my system is almost completely silent, my Zalman PSU, 7000A Cu and Zalman videocard cooler with optional fan make no noise.

I just tested them on 5 V, the papst turns so slowly that there is almost no airflow, the noise must come from in the case, has anyone a solution. Out side the case at 12 v they make no noise at all, has anyone a solution, the case is a Lian-Li 6070 so it is already equiped with dampening material, although I think it could use a lot more.

Mu HD is a Seagate Barracuda IV (so one of the most silent on the market) , it makes almost no noise. If I run my system without the casefans it is almost completely silent.

I suspect the Papst fans transmit a lot of vibration to the case, I have just ordered some Vantec Dampener kits to remove vibration of my 80 mm case fans.
