I mean, its not a bad cooler at all but the question is if its been maintained within that year of use. As long as none of the tubing has any damage then just buy some rubbing alcohol (Anything 90%+ works 99% is the best) and you could use anything from a coffee filter to non static paper towel and clean off the old thermal paste and reapply some new one and it should work just fine. Make sure the fans are working properly and don't have any dust or damage done to them though. But if everything checks out it should be all good. Have fun with that new PC!
