    Default 240 thick vs 280 reg radiators

    I was doing some math trying to figure what radiator would do better. In theory, 38mm thick 240mm rad should be slightly better than a 25mm thick 280mm rad. The total area volume of the first is 1,904,400 cubic mm. The second is only 980,000 cubic mm. However, math doesn't always add up to experience. Strange enough question I know but for those who've used both, which one seemed better to you? (Assuming all other factors are the same, fin density, material etc.)

    You will need stronger fans (static pressure) on thicker rad beyond that, concentrate on area. the more area you have the bigger diameter fans you can use which in turn means they can run slower rpm to achieve the same throughput of air.

    The first big quiet rad was the MORA. since that one you can buy bigger still. there were also a few odd ones like 200 x 400mm (phobya) that you might consider if still available.

    Or build your own like I did about 4 years ago. Central Cooling

    Just remember that even with a MORA or similar you will only get down to 3-4 above ambient

    Well, counting all dimensions, the thicker 240mm rad should give more surface area potential than the thinner 280mm. But that surface area is stacked more rather than spread out. The reason I ask is I'm eyeing those new Cryorig coolers and kinda wonder if the 240 might perform slightly better since it has the 38mm rad.

    The surface area of the face matters substantially more than the thickness. If all things are equal as far as materials, fpi, channels,etc, the 280 will provide better heat dissipation.

    Why not just buy a Swiftech and have significantly better performance and far less noise? If there is a Ducats Superleggera at a similar price, why buy a tricycle?
