Unlike the stock heat pipes supplied with the DB4, the LH6 heat pipes run parallel to the CPU mount and exit towards the top of the motherboard (above the CPU location). For that reason, there must not be any tall components on the motherboard above the CPU socket area that would block the heat pipes. These tall components are typically VRM cooling heat sinks or tall capacitors, so please pay attention to this when considering the use of the LH6 Kit.
