Ideal CPU fan RPM

[abbyseemslegit]

I use speedfan and it says Fan1 : 51 rpm. I think it is the CPU cooler (which is stock). Please tell me if I'm wrong or the CPU cooler is bad (I used it 2 years). Task manager says 60% CPU Usage / 100% and the temps are 50C in the same cases. Only when I exit from the game it gets cooler.

Most CPU heatsink fans are connected to the motherboard via a 4 PIN connector. This means that the cooler can fluctuate in RPM so if your system is idling then the Fan on the cooler will run at a slower RPM. When in a game it is normal for the CPU to become hotter and the fan to increase. You have nothing to worry about.

but is 50 RPM enought?

Use this to check your RPM instead. http://www.cpuid.com/softwares/hwmonitor.html

Without knowing exactly what your CPU & cooler are it's difficult to be certain, but it's a safe guess that either that isn't your CPU fan or Speedfan isn't reading it properly. 50 rpm is not enough, yet 50C is quite safe and normal, and wouldn't be expected under load if you had virtually no fan spin.

If you want to be absolutely sure take a look at the fan while the PC is running. It'll be pretty obvious as to whether it's running normally or at < 1 rev per second.

- that will cook your cpu. That means the fan makes 50 revolution per minute. You're reading it wrong. For me i have my cpu fan run max when I'm gaming(around 2200rpm) on stock cooler coz my ambient temp is quite high so it all depends on your room temp. Try to use hwinfo64 to monitor your fans and temps

running an older OS as it looks like you are doing could cause some compatibility issues with Speed fan and HW monitor. Some's sensors may not be read. Like others have said check inside of the case to see the heatsink.
