Replace 4 year old close liquid cooler during rebuild?

[NAC]

So I have an Antec KUHLER H2O 620 which is about 4 years old now. I'll be rebuilding my system soon. Should I replace this cooler if I'm happy with the performance? On the one hand, the pump is 4 years old and runs say half the time - so 4 * 365 * 12 = almost 20k hours. But on the other hand I have fish tank pumps which are three times older and have run non-stop in all that time (like 100k hours). Thoughts? Anyone had a close loop water cooler fail?

Hmm... the MTBF (mean time between failures) for other Antec units is 50,000 hours. Antec site doesn't list it for the 620. I'm leaning toward re-using it. I think I may be sure to enable alarms / auto-shutdown for the CPU in the new build.

just blow out the radiator for any dust bunnies which could of reproduced while it was being used.

Other then that, there is no maintenance required.
Keep an eye on that pump tho, I wouldn't trust any MTBF from china unless it was tested by a reputable testing company.
