High temps water cooling?

I've had my H100i GTX for about a year and a bit now, and one of the tubes is warm and the other is sort of cold. My temps randomly go from 35 degrees to like 49 degrees occasionally, I was wondering if this means the pump is either weak or failing? CPU is an i5 4690K OC'd @ 4.0GHz.

Since they're supposed to last around 5 years, I was hoping to reuse it for another 3 since I've only been using it for just over a year. Gaming the temps seem relatively fine, in battlefield 1 they can go as high as 55 degrees on ultra settings 1080p 144Hz.


Thanks.
