Re: Reducing fan noise on an E420R

There are machines sold with 2 CPU's so i guess it might work. I'm sure
you still can use the 4GB. This UltraSparc server is not a Numa
architecture.

I doubt that you can get the system quite. I experiemented with my
Ultra 5/10 system and found that most of the noise is not generated by
a loud fan (replacing it helps but does surely not have the effect you
think), but by wrong air circulation and vibration. With a 15db fan you
get almost no airflow. I doubt it will be enough to push air over CPU's
more then 10cm away. You can simply measure temparature with your hand
after 15 min of operation. If you can touch the CPU cooler without
burned fingers it's okay.

The best solution is to go and get a Intel/AMD based server. I started
another thread in this newsgroups pointing out that in my experience
SUN completely failed to produce any SOHO server. Noise and energy
sucking were one of the key problems for me too.
I'm now using a Pentium III based completely fanless server.
