H90 Blast From The Past-Should I Still Use It?

[Ben With An En]

I just unboxed an H90 140mm AIO. I purchased it new in 2014, but it has been sitting in a closet ever since. There is some 'sweating' on both of the rubber tubes right where it is connected to the rad via the plastic clamps. Some flexing and movement of the entire assembly does not reveal any leaks. The tubing feels rigid, does not have any visible cracks, and still smells like freshly molded rubber.

Does this seem ok to use? 

I plan on using it on an I7-4790 which I will be swapping into an old pc (I3-4130, Asus H87M-Pro Mobo, AMD Rx 6600, 2 x 8 GB mem, 500 GB Samsung 840, 650w EVGA Supernova, Lian Li 011 Air Mini) used for gaming by guests ( Minecraft, Roblox, Train Simulator)
