TOO DARNED HOT

I’ve been watching the rebellious mood that’s growing among Microsoft Windows 11 users with a degree of (not very nice) complacent amusement, as someone who dumped Windows in favour of a Chromebook more than eight years ago. Actually my defection was as much an accident as an example of prescient wisdom. When Dennis Publishing moved to new offices, then CEO James Tye took the quixotic decision to deploy Chromebooks to all, I took the opportunistic decision to borrow one and, being totally brassed-off with Windows 8.1, immediately became hooked. The Asus I bought for myself still works well and had been a source of great pleasure but for one problem – Google stopped supporting its version of ChromeOS with automatic updates about a year ago, and I started encountering apps that demanded an OS update I couldn’t procure. So I splashed out £229.99 on a new Asus CX3402 Chromebook Plus, which has a better screen, twice the memory, an 8-core Intel CPU and 10 years guaranteed updates. Migrating to the new machine was as arduous as usual: charge the battery, switch it on and wait 10 minutes for my online life to come down from the cloud. There were two extra chores though. Because in all matters digital I’m very far from being a trusting person, I also keep data I consider crucial on a local 128Gb memory stick that lives permanently in one USB port, so I had to unplug that and plug it into the new machine. Another quirk of mine is that I don’t really like touchpad cursor control and so use a Logitech Wireless Mouse whose dongle lives in another USB port.

I periodically backup the contents of the USB stick, a tiny metal-cased one from Integral, for which purpose I swap the Logitech dongle for another backup memory stick. A few weeks later I was doing such a backup when I noticed that the sticks had become very hot. Not warm but hot, hot enough to make me flinch on touching them, hot enough to worry. So I went online to the source of all wisdom which is Reddit, where I discovered that hundreds of people were reporting the same experience, not only with Chromebooks and with a variety of brands of stick, but in all cases when using them in USB-C ports. The consensus was that it’s OK, it’s because of the huge capacities of the current generation of sticks and the poor ventilation of the smaller cases. I pretended to believe that and to live with it for a few more months, until I started to get unreliable behaviour from the toasting stick. First it started unmounting at random times, though it always came back after unplugging and replacing. Then during a backup session, ‘copy failed’ messages and directories going missing from listings, at which point I panicked. I dug out my original old Asus where I confirmed that the contents of the stick were in fact intact, and that it didn’t get hot, and I carried out the backup there on the cool older USB ports. 

Something clearly had to be done because it’s become part of my work practice to keep this tiny, unknockoutable, USB stick permanently in place, and changing to some huge protruding one wasn’t acceptable. My first recourse was a heat-sink, cobbled together by wrapping the Integral stick tightly in aluminium cooking foil held in place with a 15mm binder clip with the handles detached. This worked, dissipating enough heat to reduce it to just warm to the touch, but it was too inelegant for me to live with. I couldn’t find any hard info online about which brands were most liable to overheat, but my own collection accumulated over the years revealed Sandisk, Patriot and Tab all got just as hot. As I was dolefully scrolling down the endless Amazon list of sticks, one from Samsung caught my eye because it looked nicer: the same shade of grey as my computer, short, fat and shiny. I ordered one and discovered that it’s just as fast, and barely gets warm… 

What moral to draw from this story I’m not really sure. I’m not a semiconductor engineer and can’t find an adequate explanation online from anyone who is, as to why such a huge discrepancy in performance exists between brands. Does the difference lie in the chips themselves, the design of the cases, the electrical interfaces or a problem in USB-C sockets? Such silence is deafening and disturbing when data loss is a distinct possibility. But of course the computer is becoming very much the poor cousin to the smartphone, for which such sticks are not relevant and for which professional standards of data hygiene are barely relevant either.
