true; i have 1 since launch day and still going strong; i move my pc once a month like 10 miles on "bumpy roads" like you say
(well i have a jeep YJ so every road its bumpy
) and i the motherboard is fine, no problems at all
and for the fun/testing i installed 3 Cooler master excalibur: now i have 5/6 degrees better temps than before under full load (full rpm) and i can beat any CLC systems available easily
8120 4.6ghz 1.41volts inside a thermaltake chaser MK1 with all fans installed (rear fan and grill removed, top front intake, rear top exhaust) 43degrees all cores full load
best air cooler available
