Abit IX38 QuadGT Intel X38, Uguru, speedfan and fan control

NeilF · 7 Oct 2008 at 15:20

If you connect your case fans to the motherboard (I believe there are four fan headers), how controllable are they given BIOS or UGuru or speedfan settings?

Is it possible to have them turn off below certain CPU temps? To only come on at other temps? And to ramp up as the CPU gets hotter?

I'm obviously looking at this from the point of view while the system is doing nothing having fans running at a minimum, or even off, and then when the CPU heats up, the fans come on and/or speed up.

Anyone able to clarify exactly what can be achieved?

Thanks!

In the bios it will have a smart fan section where you can change how fast the fans spins in relation to the temps but you cannot turn the fan off.

OK - Hhow definable is that? ie: Would you be able to define the min/max RPM according to the min/max CPU temp? Or is it really simplistic so you just flick an option and the motherboard just does its best with little defining by the user?

It’s in the bios this is the section you need, I believe this is your motherboards bios options,

Have a mess about with the settings you need to reboot once changed and load into windows to see if they have changed.

I don't own the MB, just looking at what's possible...

The manual seems to imply you can control FAN1, and FAN2-4 (in a group).

The question is how low can the RPM or Voltage be set? ie: Could it be set to 0 to turn fans off!

If the min is 60% that's not very low

You'd want at least 30%!

Anyone have this MB? Are you able to see how much of a range of speeds you have over the case fans connected to it?

uGuru & FanEQ is the best in-BIOS mobo fan control going.
As a rule (I don't have an IX38) you can adjust fan voltage (down to 6V), high & low temp values & have a choice of 3 reference temps (CPU, system or PWM) to work from for each individual fan .

imo more likely CPU, SYS & Aux1 as 1 group & the other headers as another group.

So given the scenario of this motherboard in an Antec900 case, the tricool fans could all be connected to the motherboard and their speed automatically ramped up and down.

Also, if you wanted to run slower then 6V, your could use their switches (eg: low/medium instead of high).

if they are 3-pin, yes.

I suppose so but I have no experience with Antec tricools.

Even if the RPM wire is not there? ie: The MB will not detect the RPM...

The mobo controls them through limiting the voltage but tbh with Antec Tricools there is not much point, in an Antec 900 pretty much any modern rig will be kept cool even on the "Low" setting with the rig at full-load.

http://www.antec.com/uk/productDetails.php?ProdID=75120 says "Fan-speed monitoring capability included (requires compatible motherboard)" so I guess that they have an rpm signal cable but as I said I have no experience with those fans.

Oh! Someone else reported the ones supplied in the case do not have this wiring... ie: They are not the same as the retail version you've linked to...
