Why don't companies make graphics cards with very large centrifugal fans (and why not 2 or 3)?
Just now, Guy Marshall said:Thanks for the quick reply! You make a great point that I never even thought about! I suppose you could stick the fan to the very far side of the card as much as possible and fill the rest of the card in as many fins as possible? Or make the card much longer as some high end cards already do. Not sure if this is feasible or not though!
It should be, see the Vega FE cooler:
If they made it a bit wider like AIB cards (see the EVGA FTW series and MSI Gaming and such, they make the actual PCB and card wider and a little bit longer) they could fit a bigger fan, and then there's a good amount of space to fit a larger heatsink. Making the GPU slightly thicker (2 1/4 slot or something) could let you get in a thicker set of fins. Would be interesting to see how a blower cooler given the AIB treatment would perform.
Similar thing on the Radeon VII, they cut out the heatsink to fit in axial fans but stay in a strict 2 slot form factor, and didn't make the card any wider either so it lost a lot of fin density, thus why it performs pretty badly. AIBs typically don't make derped mistakes like that on their higher end coolers, thus why it'd be interesting to see a blower pushed to the absolute max.
