Before reading Jeff Atwood's post about Hard Drive
Temperatures, I
would have thought the the CPU is the most temperature sensitive
component in a PC. That's what I focused on, when I was selecting
parts for a new desktop at
home. Jeff's article is full of details but he makes a solid point
that is often overlooked - if your CPU or video card are fried, its not
a huge deal. Sure its an inconvenience and a hassle to order new parts
to replace them. If your hard drive fails - you lose data. And HDD are
usually rated to work at up to 55C, 15 degrees cooler than most CPUs -
and temperature seriously affects the reliability of the drive.
...increasing HDD temperature by 5°C has the same effect on
reliability as switching from 10% to 100% HDD workload. Each
one-degree drop of HDD temperature is equivalent to a 10% increase of
HDD service life.
If you don't have good or recent backups, your looking at the situation
my Dad thought he was in earlier this week. The hard drives on his PC
were locking up windows, refusing to boot, and overall just causing
random errors the whole time. Of course, he tried reinstalling windows
(and surprised me by saying he's also leaving a partition free to
install Ubuntu) but the problems wouldn't go away. Using an external
usb connection, he was relieved to confirm that the drives were actually
ok and the problem is more likely a bad ATA controller on his
motherboard. A potential disaster averted.
What can you do to keep your Hard Drive cool? Jeff points at a small
window applet that can monitor it for you. If you don't have a fan on
the front of your case, you can pick one up and install it fairly easily
if you have a plain vanilla case. Hard drive coolers are also available
but a little more involved to install. I put one into my computer and
found it didn't add any perceptible noise when the computer is
running.\
