But I was in Walmart the other day, and saw a 20" by 20" plastic fan for 10 bucks. After bringing it home and cracking open my case, I jimmy rigged a cardboard funnel to my silver orb, and took out the stock fan (it blew toward the chip anyway). My systems a 900 @ 1.1 ghz, 50 idle, and 57 full load. After the installation of this fan I'm running 45 idle, and 50 full load. I don't think the silver orb is quite suitable. Any recommendations? The funny thing is my fan has three speeds, and my computer will never be dusty again 🙂
