Which are the best programmes for Windows for monitoring CPU and System temperatures and fan speeds?
Free or commercial programmes?

A quick search would have pointed at Motherboard Monitor 5 and Speedfan - both free

I almost posted a similar thread earlier. Got a new mobo coming tomorrow and not sure if the temps will be ok or not.

A lot of mobos come with the manufacturers' monitoring software on cd anyway. Have a look on the driver cd, they may already be there.
Use motherboard monitor along with samurize and you'll have the best monitoring system you can get for windows. Thats my personal opinion btw.
Note: Some newer motherboard sensors dont work with MBM.
I have been using these monitoring programs recently, mainly SpeedFan, Everest and Motherboard Monitor 5.
I have noticed a big difference in reported temperatures between SpeedFan and the other programs. SpeedFan seems to report temperatures which are about 10 or 12 deg C higher than the other programs, especially when the CPU is idle.
How accurate are these programs?
Also, I have a SilenX 40mm fan on the CPU heatsink on my VIA MII-12000. The rated rpm speed of the fan is 3500rpm. The monitoring programs report speeds much higher than the rated max speed, up to 4900rpm?
Any thoughs??
Well the fan could be spinning faster due to various reasons:
a) rpm detector is misbehaving (unlikely - usually very accurate)
b) the fan would usually spin at 3500rpm when nothing is blocking it. If it is sucking from the heatsink then there will be a lower pressure behind it, which will cause less resistance to the fan and therefore the fan will speed up. This does happen when the fan is pushing air into the heatsink as well but this is harder to explain. Depending on the conditions the fan can speed up and slow down. (sorry if i explained it crap, it makes sense in my head)
c) the voltage being supplied to the fan is more than 12V, perhaps 13V allowing the fan to speed up.
d) the 3500rpm rating is only an average, it may spin faster or slower than the rated speed.
The temperature monitoring programs are not very accurate tbh. They are only as accurate as the thermisters in the electrical components, and they can be as innacurate as +/-15C!!
Speedfan may be reporting a different temperature because it is using a different thermister - Speedfan might be using the 'on diode' thermister and mbm may be using the one next to the cpu on the mobo.
Also mbm is mobo specific and so people may have noticed that temperatures are reported too high with your mobo, so they set the temperatures to be say 10C lower than reported. (I'm not sure about this though)
Hope this helped.
