Just because it's doing the job does not mean it's good. If you had more experience with real water cooling you would understand why 99.9999% of experienced water coolers do not like or want anything to do with Asetek OEM coolers. Alphacool is now sell a much better cooler with threaded fittings, copper radiator higher flow rate pump, quick connect for adding another component and a fill port. for less than the cost of your H115i with no way to do anything to it but change fans. Only reason I can see for a much better quality AIO costing so much less is Asetek, Corsair and others have been making a huge amount of profit selling CLCs.
