Accordingly to the default automatic fan speed plan the fan starts at about 88 30% of the wattage rating. If this does not happen, a fan failure is likely. The 89 driver also provides some additional useful values via debugfs, which do not fit 90 into the hwmon class. 91 92 Debugfs entries 93 --------------- 94 95 ======================= ======================================================== 96 ocpmode Single or multi rail mode of the PCIe power connectors 97 product Product name of the psu 98 uptime Session uptime of the psu 99 uptime_total Total uptime of the psu 100 vendor Vendor name of the psu 101 ======================= ========================================================
