The final results are not very reassuring - leading us the conclusion that the NengTyi K613 is past its prime for any processor outputting more than 50W of power. The 100W thermal tests go far beyond what the K613 was designed to cope with so we are going to ignore them completely.

On the 50W, large interface die test the NengTyi K613 is meeting the conditions which are closest to its intended application - cooling a socket 370 Celeron processor. In this regard the K613 fairs marginally worse than the K609. Without any really thermal gains on any test it would seem that the K613 is not a heatsink to consider anymore. Modified, it may have applications cooling BGA chips, but other than that it is not a viable heatsink for today's processors.
