How I Fixed: The Very Loud eMachines T5048 System Fan

 

Hello everyone,

Wow, this was somewhat of an unusual fix!

A client called me up and told me that she no longer wanted her eMachines T5048 desktop. She said that she couldn’t stand the loud fan noise any longer as it was driving her crazy!

When I got to her house I certainly could hear that the fan was indeed extremely loud! But there was no need to get rid of the desktop. Here is the solution:

1) Close out any open applications and restart the computer.

2) As the machine boots up (at the eMachines logo), press F2 (to enter the BIOS).

3) Once you are in the BIOS, navigate (use the keyboard directional arrows) to the Exit Tab.

4) Under the Exit Tab, choose “Load Optimal Defaults“. When you are asked to confirm, select “Y” (for “yes“).

5) Save the changes and Exit the BIOS.

6) No more loud fan!! Awesome!

    Hello, I just read your article about the loud fan in the E-machines T5048 PC.
    I own the same PC, and have experienced the loud fan sound. I have replaced all the fans in the case (inexpensive these days) as well as the CPU Cooler (which comes with a new/quieter fan than stock).

    Maybe you can help me with an issue that followed JUST after I installed the CPU Cooler. Here goes. To install the cooler, I needed to take out the motherboard, remove the original “X-shaped” CPU cooler/heatsink bracket, and replace bracket with the one that comes with the cooler. That part of it was a bit of pain, since the old “X bracket” did not want to come out. It eventually did and I believe I put everything back just the way it was.

    When I plugged power cord, monitor, ethernet and went to power on the machine,
    I noticed the machine would power on, all fans spin and come to life, but the machine
    does not go into POST for proper boot on power-up. Also, I hear (what sounds like)
    the CD-RW being scanned every 2 seconds. Kind of a eh-eh, silence, eh-eh, silence sound pattern that endlessly repeats until I pull the power plug. Note, the eh-eh (silly description, yes) are not beeps.

    Quite possibly, I did not get every wire back properly. Most of the wires that plug in to the motherboard are easy enough to remember (or in my case, mark with a sharpie) with the exception of the front panel header wires. I was fooled by its appearance, thinking this was a solid, molded plastic connector that held 6 wires.
    I was sadly mistaken.
    Instead, it is 3 sets of 2 wires (red/white, blue/white, black/white) and this is the only doubt in my mind when it comes to “did you put everything back the way it was”.

    So, with my other computer, I googled, and I did not find my exact scenario. Other posts recommended checking power supply, so I did a swap out with a known-good PSU. Same problem.
    Tried booting the machine without the CD-RW Connected. Same Problem.

    Looked high and low for a pinout of how to connect the front panel header wires (as these wires were likely never, ever removed until now). Could not find specific “how-to” to put these wires onto the correct terminals. I’m not even sure this will solve the problem once i do get it correct. (or will it).

    Also, I was advised to unseat (then reseat) the RAM chips. Done. Same problem. I have not yet took out the CMOS battery. Will try that later.

    Would you know of any other potential suspect here? All the capacitors look ok, did not notice any popped caps or that awful smell that follows when a capacitor blows out.

    Any help appreciated, please email when you can, thanks. Adam

    I had the same problem on my E-machine, the noise was nothing unbearable, but still inconvenient. By following the steps listed the computer, when the computer was started it was instantly much quieter!

    Is there a different procedure for doing this with Windows 7? I tried to follow the steps above and could not found these two:

    3) Once you are in the BIOS, navigate (use the keyboard directional arrows) to the Exit Tab.

    4) Under the Exit Tab, choose “Load Optimal Defaults“. When you are asked to confirm, select “Y” (for “yes“).

    Hi Brian,

    No different procedure for Windows 7. The fix is in the BIOS – has nothing to do with the Operating System. You may need to update the BIOS and then try the procedure again.

    Best wishes,

    This actually worked! the t5048 sounded like a hair dryer before tweaking the bios. i wonder why it was shipped with the loud fan in the first place. i got this years ago and it was promptly relegated to a closet for many years, but i dug it out in hope of using it as a cheap video recorder for OTA since it has a nifty analog tv card. i’ll use a hd converter box, and now i can hear the tv over the roar of the fan. thanks
