Same as mine. I just got it 8 mo. ago and now it's dusty as hell. I took it to the garage and used the air compressor to blow the dust out

[my bro bought that compressor since he's a tool guy and I used it to painted my body kit and stuff. It's HUGE, 2x my size]
I went to MicroCenter today, got me some round cables and 3 of the 80mm fans 27CFM/each [maddog brand] for REAL CHEAP - They're 60% off

The fans are very quite.
My Idle (cpu/sys) temp went from 40/38 to 32/28

Great air flow is the best (4 Intakes, 2 exhausts fans). I want to Lap the heatsink but too lazy.
