A Candle-Powered Light

Open Power ElectronicsJust a little whiff of air goes a long way in cooling your power device! Notice the steep drop in #ThermalResistance of a #Heatsink at low air velocity. In this example, going from 0 m/s to 2 m/s, Rth is almost halved.

in_sympathyHey #Fediverse, maybe someone can #fedihelp me out :).
I bought barebones #Minisforum UM 890 Pro and therefore it does not come with that fancy #DDR5 SO-DIMM heatsink that comes included with pre-configured models that have #RAM and #SSD included.
I kinda like the way it is designed and been looking all over the place but failed to find it available for sale. If anyone knows a place - it'd be greatly appreciated :).
Here's a Reddit discussion:

Peter H. FröhlichI really need to disassemble and clean the Thinkpad W530 I use for work because I can now only build our distro from scratch if I slow the CPU to its minimum clock. Otherwise I cross 100C and my fan lifts the machine slightly off of the dock.
Yes I am lying about that last bit.
But yikes! All that power! And I've let the fan clog up. I am a bad person. 😞

> **In context:** Cooler Master just launched its latest coolers featuring its "3D heatpipe" technology. First unveiled in May during Computex 2025, the company's new Hyper 212 3DHP greatly improves heatsink efficiency by routing additional heatpipes through the center of the fin stack instead of just the edges.
Lucas de SenaI have replaced the noisy Toshiba fan+heatsink from my #Lenovo #Thinkpad #T430 with the quieter Delta #fan and #heatsink from the dead Thinkpad T430 that serves as organ donor for the one I use.
The fan noise was getting me crazy. It was unbearably loud. See this video for comparison:

Black Metal Stu🇺🇦🇮🇱Ich möchte diesen Monat den #Speicher unserer #Playstation5 (erstes Modell, weder Slim noch Pro) erweitern. Eine #SSD einzubauen ist jetzt eher nicht so kompliziert, das bekomme ich hin. Kenne mich aber mit SSD überhaupt nicht aus und wäre für einen #Kontrollblick von Menschen mit Ahnung dankbar. Die SSD die ich herausgesucht habe schafft 7100 MB/s und verfügt über einen #Heatsink. Ein Terabyte Speicher wäre auch absolut ausreichend. Ob das Teil aber Grundsätzlich Taugt kann ich nicht beurteilen.
