The first byte of each pair in the buffer is the high temperature threshold for the given fan speed that follows. So, for temps up to 40C, the fan is set to automatic (0xFF or 255) and since we are faking the temperature at 31C, the fan will be off. Certainly you could try running at higher temps before turning the fan on, but it might help to run the way I have it and see how your laptop , Hi, I am new in Hackintosh. I just completed the windows 10 installation on my dual boot system, and I noticed something, the GPU idle temperature on Catalina was much higher than on my windows 10. On macOS, the idle temperatures were about 50-57 °c , while on Windows 10, much lower at about, Hi guys, I don't know which part have I missed but seems the fans of my gigabyte xt6600 is not running. I installed istat menu and it proved my assumption: temperature is not detected. I tried to update with RadeonSensor stuff but something I did just messed up my NZXT Kraken LED display, Hi, Im running sierra 10.12.4 and my cpu temp is around 38-46 c, gpu 36-40c (gtx960ti). I have stock cooler on the cpu. My cpu cooler become loud around 40. I have two questions: Are those temps ok for idling ? Is hwmonitor accurate? cheers, Just after boot CPU's temperature hangs around 50c, but with time, even when idle, it can reach up to 80c., Hi everyone First post from my Hackintosh! I am using: Intel i3 3225 Ivy Bridge Gigabyte B75M-D3H Thanks to moarfish for his guide! I would just like to know what the best way to monitor CPU temperature would be? I tried a couple programs but they all needed drivers. A search in.
