It has no use fanbusing fans that run at 1500 rpm if I run them any lower they have no use. Anyway I sent a mail to www.silentpc.nl and they recommended a new product:



Wij hebben de laatste tijd wat minder goede ervaring gehad met Acousti Materialen, vandaar dat wij nu ons eigen product hebben
wat gebruikt wordt in de vliegtuig industrie.

I will do some searching on the internet and perhaps try it.

hmm. I connected all my lian-li fans to the front controll switch.
I replaced the resistors to deal with all the fans, and I can have them running at just under 6V
They still work that way.

The Lian Li 6070 has no front control switch and a Papst 1500 rpm 12db fan running with a Zalman multi connector (ZM-MC1) at +5 volts has almost no airflow.

erm, get a zalman passivly cooled case if you think that's still too loud.
or a VIA C3.µ
There's only that much noise you can eliminate.

I have found the cause of the vibrations in my case. The so called most silent 80 mm Papst 8412.. (1500rpm 12db) case fans on the market are responsible for causing the extremely irritating vibrations, even when equiped with vantec fan dampeners.

I replaced them backwards with the ADDA fans the case came with and equiped those with the vantec dampeners and gone are the vibrations.

I can conclude that Papst fans are certainly not so good as people are claiming.

Now the next thing I will do is search some new dampening material to equip my 6070 case.
