Quiet PCs maker and enthusiast ‘Fully Silent PCs’ has revealed a new open-air test build which sports a passively cooled Intel Arc A380 graphics card. Apparently the setup was a cinch, as the 15 year old Arctic Accelero S1 passive cooler mated with the Intel Arc PCB without modifications or the use of special brackets.
Intel’s 75W TDP Arc A380 graphics cards are just about the limit for no-fuss passive cooling, but we have yet to see any AIBs market such a product. The fastest currently available passive graphics card that we are aware of is the Palit GeForce GTX 1650 KalmX. The Arc A380 isn’t too far ahead of the GTX 1650 in gaming, but it has some attractive modern media encoding advantages for content creators.
Silent PCs revealed that the graphics card was fitted with an old Arctic Accelero S1 heatsink with “no modifications necessary.” The silent PC builder went on to reveal that the 53mm spaced mounting holes on the Intel graphics card PCB aligned perfectly with the Arctic passive cooler, so no adjusting brackets were required.
It would be great to see some thermal testing and benchmarks with the passively cooled Arc A380, and Fanless Tech reveals that Matt, the owner of Fully Silent PCs, is working on producing this informative data right now. The site says that the finished build will be of the open air type, and updates with temperature readings will be provided in due course.
If we peek at the pictures shared by both Fully Silent PCs and Fanless Tech, the passive GPU cooler from Arctic is dwarfed by the passive CPU cooling block. We don’t have any reviews of this exact Arctic Accelero S1 product in the Tom’s Hardware archives, but we have featured passive PC builds with the Arctic Accelero Xtreme III, and more recently (2017) modification of a GTX 1050 Ti, dialled back to 52W for unthrottled performance, and fitted with an Arctic Accelero III.
In the pictures we can see that the Arc A380 being used is hooked up to a 6-pin power connector. Some models are designed to take over 75W, so the extra connector is necessary for peak performance, but there are models without 6-pin connectors on the market.
Hopefully, Fully Silent PCs will enjoy some success with the passively cooled Arc A380, and it will be interesting to find out any tweaks that are implemented to achieve acceptable unthrottled performance. Some actively cooled Arc A380 comparisons, in the same system, would be welcome too.
