  • I NEED HELP! How can I fix this?
    I use an app to check system temps: OpenHardwareMonitor. Some people like SpeedFan, does most of the same stuff. Source: almost 4 years ago
  • Question - Are the loading times supposed to be this bad right now??
    That's not super common (but it does happen ofc). It might be worth running a tool to scan the drive and take a peek at the SMART data. I typically use Speedfan https://almico.com/speedfan.php. Source: about 4 years ago
  • Computer has come back from a repair shop wiped and is missing A vital app I used to control fan speeds and I cant redownload it. Any alternative apps?
    You'll get better gpu support from Afterburner, but if you have a weird chipset or an incompatible fan controller, good old SpeedFan still has a few tricks. Source: about 4 years ago
