PIII 450mhz on
133mhz bus @ 600mhz with Viper Ultra!!
One COOL 600mhz Machine and it runs at default 2.0 volts!
Not bad for an Underclocked Viper Ultra at 125/140.
Any speed above this became unstable on the 133mhz bus. These numbers were better than the
558mhz system with the Viper at 185/210!
InWin Q500 with "Swiss cheese breathing mods". This really
let that 120mm Sunon case fan breath! The down side is it sucks up dust but I’m
inside this case often enough to keep it clean. All side panel vents taped shut to
maximize airflow. Air flows in at bottom/front and out at top/rear. Interior stays within
1-2 degrees of room temperature.
 
Bare PIII-450 with YS Tech fans and a Gamma 28. Nylon back plate
standoffs came from Home Depot. Gamma focused on CPU back plate reduced CPU temp by
another 4-5 degrees.
3 Sunon 80mm fans exhausting the hot air. Notice the sheet metal
removed from behind the fans to let these fans breath. Makes a big difference in how much
air a fan will flow!
Inside view showing absence of hard drive rack and the 80mm and
120mm intake fans. Toggle switch allows me to use either 80mm intake fan for quiet
operation or 120mm SUNON for max cooling. The sheet metal has also been removed from the
front of these fans to maximize fan performance. Once again you won’t believe just
how much this improves the airflow. Give it a try…you’ll see
