The fan on my Cooler Master Hyper 212 Plus has just started running only at top speed (approx 2014) regardless of the CPU temp.
The MB is an M4A88T-V EVO with a mildly o/c 1055T. The idle temp is 31C. Up until recently, the fan ran as expected, very slowly during idle and gradually changing speed up and down appropriately as the cpu temp varied.
Then, a few days ago, the fan began running only at top speed regardless of the CPU temp. No changes have been made to the system. No new parts, no BIOS changes, etc.
Any ideas? Is the problem likely being caused by a faulty fan, faulty MB, something else? Any ideas regarding how I might diagnose/fix this greatly appreciated.
