New G-Drive USB 3.0 4TB - Temperature high



I use many external hard drives for video-editing.
A friend recommended G-Drives, so I just bought my first G-technology drive, the 4TB version (G-Drive USB 4TB). This is the Amazon Link:

When I buy a new external drive, I run an extensive sector test on it. Right now, I am using Western Digital Data LifeGuard Diagnostics for running that extended Scan.

All my external hard drives heat up quite severely during these extended tests. I use CrystalDiskInfo to monitor the temps in real-time. I normally aim a small usb-fan towards the ext. hard drive to cool it down during these tests.

In any case, normally, when I aim the usb fan to the drive during such a test, the temperature goes down very quickly (less than 5 minutes) to an ideal temperature - or, if i remember to start the fan when the test starts, it never gets too hot anyway.

For some reason, this G-Drive is the first drive I’ve ever seen, that does not cool down, even though I’m blasting my USB fan at it. (Actually, it does cool it down a little, but not as much as is normal) Normally, the lowest speed setting on the fan is enough, but right now I’m blasting the drive with max fan speed and it’s only very slowly (over 30 minutes) gone down from 55C to 54, 53, 53, and now 51C. 51C = 124F

Now 51C is above the ideal temperature range.

What gives? I’m guessing this is normal for this type of drive? Or is this a hardware issue?

Any idea why the drive won’t cool down? At least, the temp reading in CyrstalDiskInfo 7.6.0 is telling me the temp is not really going down to a level I’ve experienced with other ext. hard drives. I also just checked the temp with the tool HDDTune- it also states that the temp is 51C, and yellow for caution.

Thank you for taking a look.


The drives are rated for 55-60C range. The G-Drive USB has a different cooling method due to its design and its structured for air flow so it cools quickest if the front and back are not blocked at all.
