Adventures in replacing the stock Alienware Aurora R4 CPU cooling pump. Dreaded CPU fan failure prompts attack my patience!!

Jump to solution

Hi all!

So a few weeks ago while running down homeless people in my stolen fire truck while being chased by cops, noose, and the FBI in Liberty City, my Aurora R4’s pump fans began to sound like a turbine engine. I checked the cpu temps, and they nearly reached TJ Max. After a little research I decided to clean the old thermal paste off the CPU and cooler pump head and reapply using Arctic Silver 5 paste & cleaning solutions. That did the ticket, and my temps went back down to their normal low to mid 40’s at idle and mid to high 60’s during game play.

During my research at diagnosing the issue, which included replacing the stock R4 pump all together, I came across the Corsair H80i cooling pump that claimed to be one of the best CPU cooling systems out on the consumer market reducing temps by 10 to 20 degrees. So I went ahead to see if such claims were valid and replaced the stock Alienware R4 cooler with the Corsair H80i. The claims were validated! The Corsair lowered by idle temps down to high 20’s to low 30’s and the maximum temp it has reached during game play so far is 51C!

However I have a new problem, when I boot up, the bios splash screen takes an extra 15 seconds to load and then an error prompt: Attention, CPU fan failure! Press F1 to continue or F12 to set up.

When I hit F1, the system boots as normal and the Corsair works great, but since the way the Corsair H80i hooks up to a USB connector on the motherboard and draws power from directly from the psu, instead of the stock Alienware pump, which has a designated CPU Pump connector slot on the top of the Aurora chassis as well as a power connector labeled CPU fan, I am guessing when I boot up, there is some sort of start self-test which is of course not detecting the old Alienware pump because the Corsair pump is not utilizing the old pump connections, prompts the error message.

Is there a way to set up the system, in the bios (or any anywhere) so the Aurora does not keep giving me this CPU fan failure prompt?

 

I did out of irritation, partly re-installed the old Alienware pump back into the chassis, but I kept the Corsair installed and running, so the Alienware radiator and fan are just hanging out inside the chassis, safely perched on the slide out panels covering the video card. I no longer get any error messages at boot up, and both pumps are working, albeit the Alienware pump is just blowing air on the inside wall of the chassis and actually with the extra airflow, the temps have dropped a few degrees, but I would still like to remove the old pump and set it up so that I don’t get those CPU fan failure prompts at boot up.

Any suggestions would be greatly appreciated!!

My system:

Aurora R4

Bios: A11

Windows: 7x64

PSU: 875watts

Video Card: GTX 760

Isn't it JUST the Asetek's radiator fan connector that must be connected to SYS_Fan to prevent that error message. Old fan should come off.

The twin Corsair fans do not hook into the SYS_Fan connector, rather they hook into the Corsair pump head  where a usb cable connects into a usb connection on the motherboard. This is so you can monitor and control the fans in  the Corsair software.

However, your suggestion has giving me an idea: I'll unplug the old Asetek pump from  the CPU PUMP connector and keep the old fan connected and see if I still get that CPU fan error prompt when I boot. If I don't, then the easy solution is to remove the Asetek pump and install a small system fan and connect it to the SYS Fan connector.

Yes, do not use the SYS_FAN connection.  If you connect to the CPU_FAN connection, you will not get that CPU fan error at boot up.


Just use the twin Corsair fans, and discard the old Astek fan.

You will not be able to control fans in the Alienware Command Center.  You will have direct control over the H80i fans through the Corsair Link software.

The stock back plate worked fine with the Corsair unit, so I didn't have to bother with the back plate. The only issues I ran into were with the standoff screws. I wasn't sure which ones to use and my first guess was the wrong one. My Alienware R4 was built in 2012 and I needed to use the LGA 2011 standoff screws.

Yes, that is where I was going with that.

Thanks Tesla! Your suggestion has fixed the issue. And by that, I mean, I did misread the installation instructions of the H80i, yes I was suppose to connect a four prong connector into the CPU_Fan connector from the Corsair. No error message, and the Corsair runs without any issues.


Now I don't need to have anything but the Corsair H80i cooling things down while I mow down shady jet-setters and homeless people in my stolen government vehicles while the heat chases me down!

Hi, i'm very interesting in your replacement solution. Can you post some photos (h80i pump installed, connector settings etc..)? thanks

I'm not english, so i'm not sure to understand exaclty what you have done.
