Default Philip's new toy: Thermographic camera

Jonny already knows, but I'd like to tell the rest of the enthusiasts around here:
I've got a new toy - a Flir i5 thermographic camera. I've already used it for some temperature pics of the Sea Sonic Fanless Platinum and of the Streacom Nano 150.

For the Sea Sonic, I removed all screws before testing, but I didn't remove the cover until the unit was ready for the thermographic peep-show. Then I removed the cover, took some pictures and put it back on.

It was my first try (review will be published as soon as I'm done), but I'd like to use my new toy for all psus. The problem there: Are the results still valid? Removing the cover and taking pictures means that the unit lacks cooling for 10 seconds before measurement. How fast do the parts heat up?

I'm aware of the dangerous voltage inside a psu - touching parts might mean my bosses at computerbase should look for a new editor^^.

Cool toy, but where are the pictures?

Pictures of the Streacom Nano 150 will be published soon. My colleagues are already proofreading the review. I'm going to post the link here, of course.

The Sea Sonic might need two weeks, because I've got two other reviews to do before.

I think he meant the pictures of Flir i5

BTW 10 seconds without cooling at higher load ... hmmm wouldn't be advisable, and with removing the fan for that period of course they wouldn't be valid.

Maybe you'd have more luck if you load the PSU and then plug out the AC cord (and quickly remove the cover/fan). That way the temps would stay pretty much the same and you would avoid the risk of overheating

Of course it depends on how efficient the PSU is and how big the heatsink is. So can't you just take a picture before and after?

I've always been curious... since the camera should just pick up heat, couldn't you take the picture with the cover on and the fan circulating air and still pick up the heat of the PCB? That way you could see how effective the airflow cools the core components within.

As soon as you pop open the top, there's no airflow so your components heat up right away.

@jonnyGURU:
If I do it your way, I would measure the temperature of the fan grill and the fan. The metal and plastic has it's own temperature which is usually different from the elektronics.

Last time I only used the camera for the streacom Nano 150 (pico psu) and the Sea Sonic Platinum Fanless. Removing the the cover is not an issue with passive PSUs which do not use the cover for cooling.

Too bad your "computerbase.de" text gets applied over the top temperature so I can't tell the peak temp.

I think you should also be able to disable the date and time, which should allow you to center the psu better.

Anyway, the flir will scan the image and measure the heat reflected.. it shouldn't be too bothered about the grill of a power supply.

Maybe you should see if the flir can accurately detect the temperature through some glass/plexiglass/policarbonate materials (various glasses let through various emissions , camera may work better or worse with some types of glass) . Once you find a suitable one, maybe you can replace the top of power supplies with a custom top and original fan.
