Well I havn´t tried repasting before, but I´ll probably have to at some point anyway. My main concerns are bending/damaging the heatsink, or leaving some old paste/ or stuff i would be cleaning withf you're comfortable doing a repasting, you could also try that. Maybe it was not done properly by PCS? If you don't want to do it yourself and have confirmed that this is not normal behaviour, then sending it back is the only option unfortunately.
Don´t know if you any any adivse if it comes to it?
