Regulator fan speed with temperatures

[cobrakaun]

Hello everyone,
I ask you for help... I read in forums and on the internet on this but I remained a little in doubt.

I need a apparecchietto type rheobus but allows you to adjust fan speeds according to the temperature. I want every fan or group of fans could be combined with a temperature sensor (not that I want all fans to increase and decrease tours together under a single common sensor).

Can you recommend some good solution maybe not expensive?
I found the Innovatech Fan-O-Matic that I believe will be good for my case but is an inappropriately cost.

Thank you

Hello, see these:

Lian Li TR-5B Multi-Controller - 32 €

NZXT SENTRY 1 LCD - € 35

Zalman ZM-51 € MFC2

One can be suitable for you, I think.

I think that relates to some controllers to regulate according to the temperature and independent channels.

The new fantastic NZXT Sentry LX. In case you have a ASUS that has a chance to mount sensors temperature, through bios you can think what you have proposed.

Meanwhile, thanks for your suggestions.

Yes try a controller that regulates the speed of fans in an automated manner according to the temperature, possibly in an independent manner for each fan using different temperature sensors.

A total of 5 fans would have 2 pairs of which could put them on the same channel and then using a single sensor (provided that it is possible to put together two fans without exceeding the maximum load controller)
The other 3 fans should be on other 3 different channels.

the first that I marked does what you ask, that only has 4 channels, you can adjust the speed depending on the temperature sensors which are obviously 4, one per channel.

The mobo is not a Asus but a Asrock 945G-DVI which also has only two attacks for the fans and I do not know that loads based.

so should go well....
The 4 channels should work. Whereas 2 them recover from connectors on the motherboard that allow however to control at least 2 more fans.

What I can not understand is whether the Lian-Li also allow the fans to turn off (which is short range of regulation) and what is the maximum load per channel (I saw that some rheobus problems damage the fans with more avid current).
Finally I was looking for the values of temperature and nutrition using the Lian-Li ... es. 40° the fans are fed 5V, 45° to 7V etc.
