SpeedFan 4.13

SpeedFan is a freeware program that monitors fan speeds and temperatures in computers with a known monitoring chip. Its main feature is that it can control the speed of the fans according to the temperatures inside your pc, thus reducing noise and power consumption.

What's New?


it looks like under extreme circumstances, SpeedFan could hurt the monitor connected to an nVidia Video Card. This happened only while doing a SEND REPORT. For this reason, version 4.13 was written. Version 4.13 greatly improves nVidia Video Card support, makes sure that some, possibly offending, checks are no longer done and COMPLETELY REMOVES NVIDIA VIDEO CARD support in SEND REPORT. You can safely use the SEND REPORT facility from version 4.13 on. This is the first serious, yet very rare to happen, issue ever reported for SpeedFan.
