Pretend that you didn't see my tittle 😉 But one thing that stands out right off the bat when you compare the two is the length of the warranty. The TT comes with 1 year warranty vs H100i's 3 year. Another thing to note is, the H100i is compatible with Corsair link Software, where you can control LED pump color, customize fan curve, monitor CPU temp, and many more using a single application. Not sure if the TT cooler has that similar feature, but I could be wrong, I just didn't see any in the hardware spec.
