Front CPU Fan constantly running at full speed.

September 10, 2019 at 12:55:03
Specs: Windows 7
Hello,

I have a dell precision T3500. My service warranty expired at 2015. Whenever I boot up my computer, one of the fans [front fan] is constantly running at full speed during the duration my computer is running. This problem started about 8 months ago. I have reapplied thermal paste [arctic silver], changed the battery in the motherboard, I've opened the case, cleaned out the fans from dust. I did a diagnostic and the message read, "error code 3700:011B front fan speed is incorrect." Your feedback would be much appreciate it.

Thanks
Chris

did you try to unplug/re-plug the fan connector into the motherboard?

you could also try changing some fan settings in the bios/uefi

other than that you could replace the fan, tho it could still be an issue with whatever is controlling the fan.

"I have reapplied thermal paste"

Did you do it correctly? Vertical line method?

Hello hidde663,

How do you change some of the fan settings in the bios/uefi setting?

Does this 'front fan' cool the cpu heatsink or does it just evacuate the air in the case? If the latter (and you haven't made other changes) then the fan probably needs to be replaced.

If you can't see anything in your bios settings, try SpeedFan.

Hello Johnw,

I downloaded the software, Argus Monitor. When I first opened it up, a message appeared saying:

"ARGUS MONITOR - S.M.A.R.T. - CAUTION DRIVE 1, SEAGATE ST500DM002-1BD142

500 GB, SERIAL Z2AS0685 ATTRIBUTE REP. UNCORRECTABLE ERRORS HAS A RAW VALUE ABOVE ZERO.

THIS MESSAGE IS INTENDED AS A PRECAUTION AND IS CONTROLLED BY THE EXTENDED S.M.A.R.T. MONITORING OPTION." end of message...

What does the message mean? Any solutions?

Thank you,
Chris

Hi Chris, it means your drive may be failing.

Run the Seagate tool.

As far as the front fan is concerned, see f there is another unused 4pin Fan connector n the motherboard. If there is try switching the fan over to the other connector (Fan1, Fan2, Fan3, etc) to see if it resolved the problem. If not then replace the fan.

As far as the hard drive warning, Yes, Seatools Short Drive Test should reveal any issues with the drive. If there are minimum issues it may be able to resolve them by cutting out sectors but if the problem is serious or many minor sector issues then it needs to be replaced ASAP ad t will tell you that.
Consider an SSD drive.

Hello Fingers,

Is there a way to check to see if the fans are bad and/or have failed, needing to be replaced?

Do A Proper Power Reset & then test to see if your fan speed is Ok.

Doing proper power reset is easy. It isn't the same as simply shutting down your machine.

A proper power reset means draining all the electricity out of the system.
This will properly reset the hardware and also clear volatile memory, it also helps since Windows will be restarted after, clearing out any memory leaks, not enough system resources or other problems that might get in the way of the repairs.

Have you ever heard someone say their computer wasn't working right, so they unhooked it, took it to a computer repair shop and when they got there the system was working fine? This is because the power had drained out of the system!

(Step 1) Shut down and power off the computer.

(Step 2) Once the computer is powered off, unplug the power cord. If it is a laptop also remove the battery. It is important that any way for the system to keep getting power is unplugged or unhooked.

(Step 3) With the power cord unplugged and the battery removed (if you have one), hit the power button a few times as if you are trying to turn on the computer. When you do this and the computer tries to turn on, all the electricity is drained out of the system.

(Step 4) Plug the power cord back in and reinsert the battery (if you have one) and turn the computer on.

You can test a fan to see if it is running by choosing a different fan port on the motherboard or getting a Molex to fan adapter plug so the fan is directly connected to the power supply. The disadvantage to this adapter s that unless you also get a fan speed controller, the fan will only run at full speed.
You can also try it on another computer.
Seriously though if there is any question, a case fan is very inexpensive and commonly between $5. and $15. US and rarely more than $25. If you just purchase a new one you will be done with it if it works and know for sure that it is somewhere else if it does not.

Hello Johnw,

I managed to buy a new hard drive ( Seagate Barracuda 1TB 3.5 Internal Desktop EDO DRAM
7200 RPM HDD SATA 6Gb/s ST1000DM010 ) which helped to solve the argus S.M.A.R.T. Caution Message. I also did a Proper Power Reset with the battery removed. It didn't solve the problem. I thought might as well order a new Dell DC 12V 4 Wire 5-pin Dual Cooling Fan Assembly HW856 from amazon.

Do you think that I should of gotten a little bit more expensive, a faster processing speed hard drive instead of the one that I had purchased recently for my dell precision T3500 Workstation Computer?

P.S. Also, my computer does run very slow. Maybe I should download HijackThis and post its results.

Thank you,
Chris

Hijack this is too outdated these days and can get things wrong. For the time being I would run these two freebies from MalwareBytes if you haven't already (run AdwCleaner first):-

AdwCleaner:
https://www.malwarebytes.com/adwcle...
Download and "Save" the file somewhere. Go to the saved file then double click it to run the program. Run the "Scan", followed by "Clean & Repair" if anything is found.

MalwareBytes:
https://www.malwarebytes.org/
(use the "Free trial" which can be stopped afterwards if you wish).
After the install go to "Settings > Protection". Under Scan Options move the "Scan for rootkits" slider over to On and Run the Threat Scan. Quarantine anything it finds.

If either of them find anything please copy/paste the associated logs on here.

Always pop back and let us know the outcome - thanks

You wouldn't notice any difference in speed with a 'faster' hard drive. The limiting factor is usually ram but your 4 gig ought to be enough but with a 64 bit OS you can always add more. Hijackthis or other computing.net recommended adware/malware detectors would be a good idea. Be careful when removing adware as it's sometimes linked with legitimate software.

Hello,

Purchased and installed a new Dell DC 12V 4 Wire 5-pin Dual Cooling Fan Assembly HW856. Even with the new fan assembly installed, they are still running at full speed. The problem persists, I can't figure out what else it could be causing it.

Thank you,
Chris

Did you try a different fan port on the motherboard? If not then try one.
Did you look in BIOS set up for fan controls, there may be some setting that effect the fan. If there is a dynamic setting, it should be a good option. If the setting accidentally changed to something like 'Max' or 'Water Pump' then change it back.
If nothing else works then you can purchase a fan controller that plugs into a spare Molex 4pin connector and has a knob that allows you to set the preferred fan speed. Experimant with it to see how your temps go, use something slightly faster than the minimum that keeps your system temps fairly level and under control because it will not be dynamic but fixed at this setting unless you mount it external and adjust manually as need (too much like work unless gaming, then mark two settings that work for both).

Hello DAVEINCAPS,

"Does this 'front fan' cool the cpu heatsink or does it just evacuate the air in the case? If the latter (and you haven't made other changes) then the fan probably needs to be replaced."

The front fan cools the cpu heatsink.

The fan needs to plugged in to a socket monitored by the bios. I assume it already was because it was giving you an error message which you wouldn't have gotten if it wasn't being monitored. As Fingers suggests try plugging it into a different monitored socket. If the wiring doesn't reach you may need to remove the fan and hold it while testing another socket.

If it's not a bios setting and everything else seems OK then maybe the cpu is getting too hot (or the bios thinks it is).

Is this how things look inside your box?
https://linustechtips.com/main/topi...

The fan blowing to the CPU cooler is controlled by BIOS. Either the circuit controlling the fan is broken or BIOS detects a hot CPU. Is there a temps & voltage monitor in BIOS? if so what are the temps there?

Hello sluc,

"Is this how things look inside your box?"
https://linustechtips.com/main/topi...

Yes, that is exactly how my dell precision T3500 looks like inside.

"try plugging it into a different monitored socket"

In the link above, can you show me where inside the T3500 can I find a monitored socket/fan port?

How do you look for the BIOS settings for the T3500? I can't seem to find it when I hit F2, F5, F12 or any other of the F key(s).

Thank you,
Chris

According to this:

https://itstillworks.com/how-to-get...

You press F2 as soon as the keyboard lights flash. Typically if you press it too soon or too late it won't work.

Are you using its original keyboard? Sometimes wireless or USB keyboards (if not original} won't work until windows starts to load.
