Unable to control the CPU Fan Core i7 Cooler Alienware Aurora(Runs at only 5%estiamted speed)

Is there really no help for this?

Is there not possible way to get my fan to go back above 1000RPM? or whatever. I really need it to the processor is hitting over 50C when i play games. I have a mini fan jerryrigged onto the radiator but its to small to make any real difference.

I really need help with this, this is the only computer I've got and theres simply no way i can replace it.

The CPU cooler and sensors are controlled by the MIO-Board, so trouble-shooting should start there.

Shut-down machine properly so it will turn off. Unplug from wall or UPS. Hold down power button for 20 seconds to dissipate any electricity in machine and MIO-Board. Wait another 20 secs before powering up. See if that very simple procedure resets MIO-Board.

Run Dell Diagnostic on the MIO-Board. This will check it and also has been known to reset it in some fashion. If it is detected and tests good, but still won't work, try re-installing the software ...

Completely Uninstall Command Center and reboot.

Install the latest Command Center (v2.6.1.0) and reboot.

Test operation.

Aurora
------
The CPU Cooler has 2 separate cables. A larger one for the pump, and a smaller 4-pin one for the fan.
Looks like they both plug into the connector panel strip "Interior Lighting Board") that runs along the top of the Aurora.
The little 4-pin cable that comes off the top off the radiator/fan assembly ... be sure it's plugged into SYS_FAN connector (CPU_FAN is incorrect ... it will spin, but not report in CC).

In CC, "System Fan" should read around 1200 at idle
In CC, "CPU Pump" should read around 1400 at idle (or just "Running" in CC v2.6.1.0)

Did you ever find the MIO Board "Reset Jumper" and perform those procedures?

Configuring software for Proper Cooling

Prerequisites:
- MIO-Board must check good in Dell diagnostics (and attached sensors, fans, lights, etc).
- Clean install Command Center (Uninstall old one, reboot, Install new one, Reboot).
- Command Center and Thermal Control (sub-app) seem to start and run ok.

Go to Thermal Controls, be sure Current Profile is set to Default. Make a small change and then click SAVE. Give it a few minutes to update MIO Board. It might not hurt to do the same for the Lights.

Go to Control Panel, Power Options. Be sure the selected Profile is High Performance.

The CORRECT operation is  ... when you first turn on the machine, all the fans run at 100% for a few seconds. They should slow down to a normal level while the BIOS screen is still up. If the INCORRECT parameters are saved on the MIO-Board, the fans won't slow down until Windows (and Command Center) load completely.

Once the micro-controller based MIO-Board is programmed properly, it seems to have no problems doing it's cooling duties ... even without constant control from the OS or Command Center.

Yes, i found it after watching a tear down video and spent the next 6hours doing the reset, test, and command center install with CCleaner before installing CC.(Just as instructed on the first Post.)

I have sorta some proof that I used to be able to control the MIO board/System Fan on the Liquid coolers raditor.

this is today March 2 2011

I guess ill just have to do it again.

As a temporary assist the little minifan i have jerryrigged into the system(Laptop cooling mat fan powered via USB Power, not pluged into the mobo at all)

When i restart the computer the Fans go to max while its rebooting but when the Alienware Head logo pops up... nevemind im going to check it again and listen to make sure.

I had the same thing when I installed the beta CC and went back to the official CC. It let me control the CPU cooler fan. After a restart it went away. What version of CC did you have ?

Press the Updates button. It will show the version number in the Dialog Box title.

I DO NOT recommend you use that to update it though ... an un-install and clean install it better.

I dont know, I cant seem to find a single version decsription anywhere.

Version 2.6.1.0

I did clean install.

It won't let me install it until the previous Command Center is removed.

Version 2.6.1.0 I did clean install. It won't let me install it until the previous Command Center is removed.

Ok good ... but backing up a bit ... did you read all I posted carefully?

Especially, have you verified the connector name where the radiator fan in plugged in (SYS_FAN) ?

Does Dell Diagnostics pass the check now?

Its always passed the check. The fans cable cant even physically reach the other connector plug.

And yes I read the entire thing carefully.

I did the same things reading the MIO reset instructions over and over uninstalling Ccleaner jumper reset MIO board  test, Reinstall Command center...

Is there anything else i may have missed?

The fan passes the check. So does the MIO board

The onlything that bothers me is that after a fan check the raditors fan goes to 100% and Stays at 100%.

Also ive noticed that if i unplug the fan, and clear the board of power(unplug hold Powerbuttong for 1minute) and then plug the fan back in then go to CC, it shows the System FAn as controlable, but It sits at 0% and I cant make the fan go faster.

The CPU Cooler has 2 separate cables. A larger one for the pump, and a smaller 4-pin one for the fan.

In Command Center/Thermal Controls (at idle):

"System Fan" should read around 1200 rpm
"CPU Pump" should read around 1400 rpm (or just "Running" in CC v2.6.1.0)

All Ambient Sensors should read about 27c

PCI Fan - 1600 rpm (4%)
- Ambient Sensor 2

Hard Drive Fan - 900rpm (7%)
- Ambient Sensor 1

According to Asetek demonstration, the speed of the CPU Pump is constant. I'm not sure what temp. sensor is being watched to control the speed of the System Fan (radiator fan), but it doesn't appear to be Ambient Sensor 3 ... because the temp. on it never changes (even under high stress).

Set PCI-Fan and Hard-Drive Fan to Manual, and then (inside each to "Use Curve")
- Line or arc from bottom left to top right of graph
- This should emulate "Auto" (with a little more control)

Active Thermals
Current Profile: Default

Under heavy stress, I've seen the System Fan go as high as 1800 rpm, but no single core has ever gotten hotter than 62c.

What do your sensors and fan rpms read at idle?

I don't know the fan RPMs of the Hard drive and PCI fan, but The way i have them working is to essentialy create pressure and send the air through the radiator.(I understand physics, just applying what i know) I can actually feel airflow slightly out of the top of the machine.

the fan sits at 1100 RPM idle it reads around 1220 average but I thuink thats because i have that little fan tacked on in front of it. and its pushing air stronger than the Radiator fan.

1100 - 1200 RPM ... that is all fine.

What is your CPU core temps?

I've noticed you have to push the CPU really hard before the radiator fan starts to speed up. The system doesn't seem to care until it starts getting hot.

HyperPI will max out your cores for a short test:

With HyperPI, I finally got the radiator fan to speed up to 1800-1900. No core ever got over 64c. If it works, try a longer test using: Normal, 8, 4M

Depends on what I'm doing.

I have Core Temp installed.
When I'm playing Prius Online TW the cores will stablize at 42~43C depending on where I'm at and doing.

But when I play vindictus the CPU heats up to over 55C

Idle depending on my room temp tends to be around 33~34

EDIT:

I had a Peek of 59C 61C 59C 59C while playing vindictus once.
