I have a 24TB Studio XL ev which I run straight into a 5K 2015 iMac. It sits on a desk by a window in a small office. It’s pretty hot in the UK at the moment and earlier I had (for the first time ever) the 3-beep / red icon showing a raised temperature. I quickly exited the projects I was working on, shut it down, pulled the plugs etc. I cleared quite a bit of dust from all the extraction vents and let it cool for a while. Then plugged it back in and started work again. It’s been fine all evening but in the past 20 minutes the Backpane 2 fan has suddenly gone into overdrive. It went from spinning at 1200rpm to spinning at 2700. Meanwhile the Backpane 1 fan dropped slightly from 1500 to 1300. I’ve never had any of the fans spin so fast. It sounds like a jet engine. The temperatures are all OK. At least 5 degrees (or many more) below the healthy threshold. Voltage is OK.
Basically should this be a worry? If the enclosure conks out presumably the data will be relatively accessible still? Is there anything I can do to prolong the life of the unit? It’s probably 2 or 3 years old and it’s my main backup. I’d rather not open the device up myself but am fairly competent with computer innards so if this is indicative of a hardware failure issue then I might be able to replace something myself.
In the meantime I’ll start saving the pennies for a replacement/upgrade.
Thanks in advance for any advice/reassurance.
