From what I understand—and this is speaking in very broad strokes—cooling for GPUs in the A4 roughly goes:front-to-back oriented fins < blower < top-to-bottom oriented finsThe general wisdom I've seen repeated is that because of the A4's layout and lack of case fans, it's particularly important to have each device clear its own hot air from the case as quickly as possible, rather than simply clearing it from the device. A front-to-back fin without a blower-style shroud doesn't corral the hot air particularly well, so much of it gets recirculated. Blower shrouds allow them to control the air better, but the distance it has to travel limits their effectiveness. Top-to-bottom fins quickly clear a good amount of air out the top of the case, preventing it from recirculating.Again, that's broad strokes that don't apply in all situations, and I definitely don't have any data to back this up, but it at least provides an explanation for why some people may be having different experiences.
