I'd like to control the fanspeed on all the following:
CPU E2220
GPU HD2600 Pro AGP
Antec True Power 330 ATX
My motherboard is the Asrock 775i65G v2.03.
Should I start a new thread or keep this one alive?

Hi,

Welcome to LQ!

Your post was moved to a new thread for better exposure.

From http://www.xpcgear.com/asrock775i65g.html
Board has two fan connectors. If you have other fans that you want to control then a fan/speed controller can be used. You can get cheap potentiometer type controllers but if you wish finer control then look at 'PWM' type controllers that will cost you a bit more.

If you scroll down to find 'similar threads' to open other threads for information.

Hope this helps!

I appreciate the welcome and thanks for the attention. Yes, the board only has two 4 pin fan headers (one for the power supply and one for the CPU) but I was under the impression that the GPU fans were also controllable via PWM control software, was I mistaken?

Hi,

Most new GPU do have 'PWM' ability. But the board you stated supports;
You should be able to control a GPU fan via the 'chassis fan point'. It will depend on the start and end points for fan controller. If the BIOS allows you set a range that fits the 'GPU' then it should not be a problem. 'fan' labeling will not show as 'GPU' unless you can change the label. Some external controller programs allow re-label.

I would use the MB fan ports as intended then add a separate controller for 'GPU'. You can find inline fan speed controllers that are 'PWM'.

I only saw 2 fan headers and they are both occupied as I described above. I was hoping the GPU could be controlled through its native port by the driver. Is this not possible?

There is a linux app that seems to be able to control the fan speed namely fanCon , maybe it works on you're system

Hi,

Some GPU/Graphics drivers do sometimes allow fan control. I believe aticonfig can be used for ATI: http://www.startux.de/linux/55-fan-s...or-atiamd-gpus

Nvidia does the same via the driver: http://en.gentoo-wiki.com/wiki/Nvidi...VIDIA_Settings

This of course will depend on the driver version used for the Graphics card.

Sourceforge indicates this software hasn't been updated since 2007. I would be quite hesitant to try this on componenets and software that were produced later. Any other suggestions?

I believe that I can only use that utility if running the proprietary driver. I am using the open source 'radeon' driver. Am I wrong?

Hi,

As I said the driver version will dictate. Most external graphic cards do control the GPU HSF to maintain temp via fan speed. You could provide external fan speed control as I stated earlier but if you do not close the loop by temperature monitor then damage can be likely.

Noted. I won't add any hardware to achieve fan speed control so that's out. I would rather not use the ATI/AMD proprietary driver so the question becomes will the utility from that package work with the open source driver or is there another functionally equivalent tool to it.

Update: I noted that libsensors4 is installed, how do I use it to check on the sensors and report?
