|What it does|
|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.
Currently the only recognized (and useful) chips are WINBOND W83782D, which is found in
ABIT BP6, and WINBOND W83627HF. If you've got any other motherboard with the same chip,
this program is for you.
I started adding other chips, but only a few of them have the ability to control the speed of the fans. If you know of any other chip with the same feature, feel free to contact me. SpeedFan can be minimized to the tray and is compatible with Motherboard Monitor 5.
|How is does it|
|SpeedFan monitors temperatures and, according to your setup, does its best to keep them at
your desired value. When choosing parameters for the minimum and maximum fan speed, try to
set them by hand (disable all the VARIATE FANs checkboxes) and listen to the noise. When
you hear no noise from the fan then you can set that value as the minimum fan speed for that fan. I suggest to use 100 as the maximum value, unless you hear so much noise from it. In such a case, you might reduce the maximum speed to 95 or 90. Obviously, nothing says that you can't set 60 as your maximum value and, sometimes I myself set it that way. Consider that when the WARNING temperature is reached, the program sets the fan speed to 100, whichever maximum speed you set. One last word should be spent over the USE FAN x listbox. In my pc, when a fan runs faster, more than one temperature changes. You can say on which fan every temperature should rely. In my BP6, TEMP1 and TEMP3 are both influenced by FAN1.
|Try to lower the speed of each fan and look at the reported speed and the temperatures. If you do not allow SpeedFan to variate any fan and set all the speeds too low, then SpeedFan won't be able to avoid overheating. My pc uses both CPUs all time (I've got two SETI@HOME clients :-)) and therefore SpeedFan has to work a lot in order to keep temperatures low. Furthermore, both my CPUs are overclocked and my case is quite small. These are the reasons why the preset temperatures are quite high. If you have got better airflow, not overclocked CPUs and some idle processor time, then you might be working at much lower temperatures (like 33 C).|
|How to setup|
|Create a new directory wherever you like, put the all files from the distribution ZIP in there and run the EXE. Set the options according to your needs. That's all.|

discover any strange behavior. I would like to receive an e-mail from those of you who try and find useful my program.
Not much: just a line of text :-)
Thanx for your attention :-)
