Reinforcing it would only do so much, better RMA ASAP, if can sell it off and then get a different cooler, RMA pumps vibrate quite a bit, out of my comfort zone. AIO, stick to corsair<< still the safest and least likely to leak if used correctly in my opinion.
Used to support swiftech a lot in the past for custom water loops as they offer easy expansion. However due to overwhelming cases of their AIO leaking (even on stock AIO without expansion) have fully moved on and avoided that brand altogether. By overwhelming I meant by 7 out of 10 people, usually occurring 6-9 months onwards from setup date.
Swiftech replied very fast though for RMA cases, usually waited 1-2 weeks before unit is replaced, customer service is still a good experience though product quality can be improved
