I've had some big hardware failures of late in my computer infrastructure.
My previously rather good and quiet IBM Intellistation (dual Xeon) MythTV
server's power supply died. The PSU, being IBM, is completely proprietary
and so the machine is now essentially defunct. Real shame as it was a nice
piece of kit.
I ended up buying a Dell Precision workstation as its replacement. This
is another dual Xeon machine, but this one was rather noisy, with two big,
loud fans drawing air over the CPUs. I tried replacing these fans (which
required me to resolder the proprietary Dell connectors) with two 92mm
Zalman fans and a potentiometer. Unfortunately these Zalman fans are
absolute crap! The idea with this kind of mod is you can turn the fan
speed down and get dramatically less noise while only slightly less
airflow. These Zalman fans basically can't have their RPM reduced by
anything significant, so they only run at full pelt, producing more
noise than the fans they replaced!
Holly got the shits with this situation and authorised me to spend
some bucks on the problem. Fortunately Danny had
recently
done all the research I needed and so I, somewhat cheekily, nabbed
much the same setup as him. Only difference with my kit is a different,
and cheaper, motherboard and a slower CPU. I also have the hard drives
I need.
I'm still waiting on the power supply and passive heatsink, but as
soon as they arrive we'll have silence again in the back half of our house.
If this is successful, I'm tempted to build myself a similar box as
my desktop.
