Hi, Recently my built in cpu fan in my Acer Aspire V3-531G started being very loud and pretty much shaking my laptop when running,so i decided to check out the rpm with SpeedFan.But it couldnt detect any fans,so i tried HWMonitor;same thing here,no fan detected. Then I got curious about at what rpm are my fans spinning and wanted to check it out, I installed hwmonitor and got a little bit suprised.
