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.

Because Speedfan is discontinued, it may not work for you, try this one.

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.
SeaTools for Windows

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.

You have to be a little bit crazy to keep you from going insane.

Hello Johnw,

I downloaded argus monitor. I ran it and the software can't read any fans that my dell precision t3500 has.

Thank you,

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.
