Although intel's specification did not tell which unit for Temperature Statistics (Log Identifier C5h), I believe it is based on Celsius instead of Kelvin. here is my P3700 SSDs result(before): Intel Temperature Log ===================== Current: 30 K, -243.15 C, -405.67 F Overtemp Last Flags 0 Overtemp Lifetime Flags 0 Max Temperature 53 K, -220.15 C, -364.27 F Min Temperature 17 K, -256.15 C, -429.07 F Max Operating Temperature 63 K, -210.15 C, -346.27 F Min Operating Temperature 0 K, -273.15 C, -459.67 F Estimated Temperature Offset: 0 C/K after apply the patch, result is Intel Temperature Log ===================== Current: 303.15 K, 30 C, 86.00 F Overtemp Last Flags 0 Overtemp Lifetime Flags 0 Max Temperature 326.15 K, 53 C, 127.40 F Min Temperature 290.15 K, 17 C, 62.60 F Max Operating Temperature 336.15 K, 63 C, 145.40 F Min Operating Temperature 273.15 K, 0 C, 32.00 F Estimated Temperature Offset: 0 C/K I also compare to smartctl's report. it match very well. also tested on Intel P3600, it fixed the problem.
