They do cost money, but an IR thermometer is your best bet. I use a surface contact thermocouple with a Fluke multi-meter. Advantage of the IR method is it's no-contact, so there's no chance of static damage or metal contacting a sensitive component and shorting it out (imagine a steak thermometer probe slipping and grounding out your VRM or hitting some other component while it's running).

IR is best, but keep in mind it is monitoring the surface temp of what it's pointed at, not the actual component temp inside, under heatsink. Also a 12:1 pattern means at 12 inches it is reading a 1 inch circle, not just the component inside of circle. At 3 inches it's reading a 1/4 inch circle.

Yea but still if the heatsink is at 100c the chip is probably higher etc smile.gif
