Well, we design and qualify Corsair products with a bit of abuse in mind! Generally, our parts are pretty rugged, and more than handle the treatment that our customers give them. So, our return rate is very low. This low return rate enables us to replace failed modules pretty much no questions asked. We spend a lot of effort supporting our customers and helping them tune their systems; they generally return the favor by not returning parts that they have destroyed by overvolting them too far.
It's definitely worth a read, even if you aren't a Corsair fan.
