ASRock announced that its new Z87 OC Formula motherboards offer a 5-year warranty:
Accidents happen, especially when you try to avoid them. But rest assured that ASRock's latest ATX sized OC Formula Series motherboards, including Z87 OC Formula/ac (with 802.11ac WiFi support) and Z87 OC Formula are protected by a special layer of Conformal Coating. As you've probably already heard, Conformal Coating protects the motherboards from conductive liquids, dust, corrosion and extreme temperatures*. And if you still feel skeptical about the lifespan of your overclocking oriented motherboards, fear not! ASRock guarantees 5 year warranty!
ASRock's Z87 OC Formula/ac and Z87 OC Formula are designed by the world famous overclocker Nick Shih. These two motherboards possess both hardware and software features for extreme overclocking, and they are also fully loaded with a set of lifestyle based features named A-Style. ASRock provides the five year warranty package as long as the malfunctions and defects occur under normal use conditions and aren't caused by misuse or abnormal operations**. If unfortunately the motherboard cannot be repaired, ASRock will replace the product with equivalent or next generation products.
* Conformal Coating may protect the motherboard against conductive liquids, but only to a certain extent. To avoid damaging your computer and other components, we still advise users to keep liquids a safe distance away.
** The details of this 5 year warranty service may vary by different regions.
