text: <s>[INST] Power Flex 400 Heatsink ovrtemp I have a power flex 400, 300 HP. My problem is went i start the drive and past a few seconds appears a fault message ( F008, heatsink over temp). so, I touch the drive and is cold. I thinks is a problems with the sensor temp. But i dont now if is a failure card. can you help me? all fans works correctly. [/INST] If your drive is operating in an ambient temperature allowed as per specifications (not too cold - not too hot :smileysurprised: ) the fans are running when you give a star/run command to the drive, and there is not excessive load attached to the drive, then could be possible it is faulty and need to be repaired / replaced... :smileysad: - fuzzy logic \\n </s>
