My fancy quiet PC has
been running hot. I thought it was Oblivion's fault, but
when I opened up the case I saw how filthy my high tech vacuum cleaner
had become.
Removing a couple of grams of dust from the heatsinks and fans brought
the max CPU temperature down from an alarming 82°C to a merely
scorching 66°C. I never thought filth would make that
big a difference.
