When working on old computers I like to try to reduce power & waste heat wherever possible. I've normally just used an infrared thermometer (Testo 830-T2) to check & compare temperatures.

As I'm producing videos, I thought a thermal imager might give a better indication for the viewer rather than just a number. A quick look on Element14 showed several for $1000's ... a bit extravagant for a YouTube channel earning about $30/month.

So on to Aliexpress where there were a multitude - quite bewildering. One key specification seemed to be the resolution. I settled on one with a (ahem) claimed 256x192 pixel resolution and the ability to record video.

This is the ToolTop ET692C with a recommended price (apparently) of around AU$670. However it was on sale for AU$245 which, after adding shipping & tax, became AU$271. It was delivered impressively fast from China to Port Macquarie - only five working days (including a day to get it up from Sydney to Port).

Overall, it seems to do exactly what I wanted it to do, so I'm happy with it. I wouldn't have paid over AU$300 for it as my needs can't really justify anything pricier.
