Recently built myself a mini-itx rig:
Asus MAXIMUS VII IMPACT
EVGA GTX 980
Corsair Vengeance Pro 16GB (2133 mhz)
Samsung 850 Pro (512 GB)
WD Black (1 TB - WD1003FZEX)
SeaSonic Platinum 860W
The system runs VERY quiet, but I noticed a soft clicking sound coming from my HDD. I’ve done an error-check in Windows and a SMART check both quick and long using WD’s diagnostic tool, everything seems fine. Usually the system is completely silent and the clicking doesn’t start unless I’ve been running the computer for several hours (like 5 or 6+ hours or so).
Just to be clear, I’m using the HDD as storage. The drive runs fine, no errors, no slowdown. I have in fact replaced the HDD 3 times over the last month with my store warranty, and each Black drive makes the same soft clicking noise after running idle for several hours. Could it be a heat related issue? A power issue? Any advice?
