arguing over
sorry.. you're just plain wrong. you did NOT account for fitting losses or tubing losses which are very significant. You also did not account for the fact that the water velocity in the Xflows is 1/2 that of the dual pass GT's which is a horrible design flaw on HWlabs part. So 2x BIGT Xflows will NOT equal a BIGT240 in performance. It would more likely be a good 20-35% lower performance, while costing more, be more prone to failure and leaks (based on the fact that there are just more components)

Also, the Xflows do not server ANY purpose for low flow setups. X-flow rads perform worse at low flow rates than the 2pass versions and do NOT improve flow that much at such low flow rates, especially when the cause of the low flow is from the waterblocks.


So in short, X-flow is the biggest waste of money to ever exist short of the bigwater.
