[color=blue]Y580 vs Y480 vs N56 interior thermal design.
[attachmentid=2900854][attachmentid=2920458][attachmentid=2904247]

According to Chinese site, Y580 has abnormal high HDD temperature due to thermal design problem where hardisk is located between the heat source CPU & GPU
HDD idle temp around 47C, it reached 63C during Furmark & Prime95 stress test.
Will it affect HDD lifespan as we may lost all the critical data?

Y580 with FULL copper heatsink but hardisk located between heat source CPU & GPU 
[attachmentid=2900854][attachmentid=2901063][attachmentid=2901126]
HDD manufacturer stated operating temperature between 5c to 55C

Test results from Chinese site http://ideapad.it168.com/thread-2209355-1-1.html
Y580 with i5-3210M, GTX660M(GDDR5) at room temp 24C,
Under idle situation, CPU 55C, GTX660M 41C, HDD at 47C which is high

Under full stress with Prime95, FurMark, AIDA64 to stress HDD
CPU & GPU at 91C, HDD at 63C
This is an unnatural level of stress that is almost never achieved under normal circumstances (including heavy gaming)

If you place a new SSD in the HDD location and relocated HDD to DVD location and doing the above stress test
CPU & GPU at 91C, SSD at 47C and HDD temp down to 43C
