March 25, 201214 yr Here's a screenie of my disks during a data rebuild. Notice where the hottest disks are located. From top to bottom: Icy Dock 5 in 3 Stock Cooler Master 4 in 3 Norco SS-500 It's a Cooler Master 590 with 2x Masscool SL-FD12025 120mm for the top (exhaust), one Scythe S-FLEX SFF21E / 120mm installed on the side panel (intake), then stock fans for the front (intake) and rear (exhaust). Going forward, I don't think I'll recommend Icy Dock.
March 25, 201214 yr For more conclusive data, relocate the Icy Dock to the bottom and see how the temps fair. It might just correlate with hot air rising, so the hottest temps may be on the top slots regardless of enclosure.
March 26, 201214 yr If your 'My Server' image in the MyMain screenshot is accurate, then your cooler and hotter drives are pretty evenly distributed across all drive cages. In the screenshot, MyMain is sorted by temperature, so of course you are going to see a nice gradient of temperature change in the list. However, if you correlate the drive's serial number with the drive's position in the drive cages (according to the 'My Server' image), then your results show that all drive cages function about equally. Unless I'm reading the screenshot incorrectly?
March 26, 201214 yr Author The sorting is for ease of reading. So it's easy to see the hottest, coolest, etc. The image is the exact orientation of discs. I looked and saw the hottest disks are in the Icy Dock enclosure (also at the top of the case), and the coolest in the middle cage.
March 27, 201214 yr It took me creating the above composite image to see what you are talking about. Your hottest drives are indeed in the top Icy Dock cage. The coolest drives being in the 4-in-3 stands to reason, as that cages offers more airflow between the drives AND has a larger 120mm fan. However, all of these drive temperatures are well within the acceptable range, I doubt you'll see any difference in drive health or longevity based on these temperature differences alone.
March 27, 201214 yr It'd be a pain, but to be conclusive I have to agree with the BRIT, you should move the dock to the lowest bays to see if the temps follow or if they go down. Honestly I don't expect you do move the docks, like Rajahal said, the temps are well within specs. I suppose with the 2x120 fans up top for exhaust, it very well may be pulling the heated air up and pulling enough of it to make the fan on the icy dock less efficient.
