1. Was disappointed in the cost cutting measures from previous models. Can the fittings be replaced with standard G-1/4 fittings as with previous models ?
2. I see noise has improved substantially (difference between Switch and best air coolers is half what was previously) from previous models . And the acrylic reservoir replaced by TG so that's a step up.
3. The fans are perfectly appropriate for the radiator used, probably won't see over 900 rpm in real world usage . High SP fans are uselss on low to medium fpi rads make absolutely no sense whatsoever. The SP concern is left over from the days when a 30 fpi radiator was "a thing".
4. The big question is , is it worth the cost ? When overclocking, not only do the $90 Noctua and Cryorig flagships come close to matching these things, kind of meaningless as long as the $45 Scythe Fuma also matches the $90 coolers. Sure you can create temps of concern using synthetics but the idea of testing is to perform such under realistic conditions ... they don't do vehicle crash testing by simuilating a car collision with a freight train at 70 mph. So if its a budget issue, then $45 Scythe versus $140 - $165 Swiftech is something to wrestle with. However, if it's between 2 x 120mm / 3 x 120mm Swiftech and any 2 x 120 or CLC / 3 x 120mm on the market, say a $165 Kraken, a a logical argument for a CLC simply can not be made. Then again, i wouldn't ship a liquid filled system either
5. Unless you will be shipping your PC back and forth to college each semester via FeEx Ground gorilas , the weight of the heat sink is not a concern. My son had a jeep set up for stiff for of road usage and he took his PC back and forth to college (5 round trips per year 300 miles each way) without issue. As long as not subject to shocks loading fom commercial shipping, the 2 pound heat sink is of no issue compared to the recommended 60 - 70 pounds of clamping force between heatsink / block and CPU
6. As I recall, the Swiftech pump (1.5 gpm) delivers about 14 times what the H100i pump (0.11 gpm) does ... have done several installations with older models including GFX card block and even pair of GFX card blocks and additional radiator.
7. Topping off the system or just augmenting the corrosion inhibitors after they reach and of life (18 mos) is simple if you plan accordingly. We install a M x M G1/4 extension on the side port with a Valve and Quick Disconnect fitting .... keep the 2nd half of the QD fitting in a drawer with 18" of tubing and when ready, just twist on the fitting , hold up the tube an add whatever ya like. Thats the issue with CLCs, when the corrosion inhibitors read end of useful life ..... then what ? And with mixed metals, the galvanic action is several orders of magnitude larger
