I got an answer almost immediately on the linus tech tips forum, they are very knowledgeable thereTo be very blunt, asking anyone to identify the AIO's make and model with only a picture of the fascia of the pump/block unit isn't going to get anyone anywhere.
Information we're looking for are images of the AIO from all possible sides(radiator, cooling block, tubes), then any identifying stickers such as a barcode or a warning sign or even a small logo etched/imprinted on the device. Stickers on the fans could also help out in this case. If the AIO was bundled with a prebuilt, include the link to the prebuilt, if the AIO was handed down, perhaps ask them for a receipt or maybe reach out to them in case they know the name of the brand.
ltt is more logical place to ask than on a PC Gaming forum, I would have suggested people over at Tom's Hardware probably guess it too, but someone above seems to have got the name anyway.I got an answer almost immediately on the linus tech tips forum, they are very knowledgeable there
