Dell E1705 - fan failed

I have a E1705 about a year old, without warranty.

I just noticed the fan has failed. It's the one on the bottom, on the left hand side (looking from top) No air is coming out from the rear.

Where do I get this part? From dell or another reseller?
Can I maybe upgrade it to a stronger fan? It appears I only have 1 fan, can I install the 2nd one? (Looking from the top, it's on the right)

How do I replace it?

 

Download a copy of I8KFANGUI, and force the fans to full speed, if the fan does not spin, then the fan is dead, if the fan spins, then the thermal threshold for the fan to come on has not been reached.

You will only be able to purchase the same fan, they are not upgradeable. Every notebook has different fans

Awesome, I could get the fan to spin with this software.


if the fan spins, then the thermal threshold for the fan to come on has not been reached.

CPU temperature was at 64C when I started, was to much? What is the system's thermal threshold for the fan to work?

Should I set a threshold via this software instead of running it on full all the time?

 

I would go into the options and play around with it, and have the fans at least come on low at around 130F and then come to full speed at around 150F.

I love I8KFANGUI, it is an awesome program. Just keep the temps under 180F or 80C and everything will be fine.

I found the fan for that notebook http://www.laptoprepairco.com/itemdetails/itemdetails.asp?ref=1056&category=fan

 

I don't understand why I need this program to control temp. when Dell should have done it.

It works well though and does give me a lot of control.


It appears I only have 1 fan. Can I install the 2nd fan easily?

 

Youre laptop has two fans, then you can select to have monitoring for both fans. Usually the first fan is for the processor, and the second fan is for the video card. In your case it is, the cpu is on the left heat vent and the gpu is on the right heatvent.

Dell cannot install that program on their laptops, because it is not made by Dell, it is made by Christian Diefer.
It is an excellent program, and it works on just about every dell laptop.

Dell usually defaults the fans to come on low at 160 and high at 200F, which is too hot for many users.
As always the cooler the operating temperature the longer your system will last.

You also cannot install extra cooling or otherwise alter the cooling solution.

 

I have the low speed come on at 48C (120F) and high speed at 65C (150F)

 

Sounds good
I bet youre relieved that you did not have to buy a new fan.

It appears I don't have a fan on the right. Looking inside - there is nothing there. Secondly, on the back, there are no outlets for the air to come out, they are blocked.

I understand that, what I am saying is, Dell should manage its temperature better. I shouldn't have to download third party software (as neat as it is) and adjust the temp. (anymore than I should have to control temp. with a car's thermostat) -- they should have programmed it to begin with.

I think their threshold is too high. Before I did anything with this software, it was running above 60C. Whether this is damaging, I don't know but 40C makes me feel better.

 

you might say that

I am glad I discovered this new software, it's real neat. I still wish Dell had managed its settings better, but this does give me options I couldn't possibly get with default settings.

 

I have many dells, and the first thing I install is fan control, I usually leave the fans always on full. I am a college student, and I buy my own laptops with my money and I like them to last very long. I do not want to pay for costly overheating expenses, so I avoid overheating by sacrificing quietness for loud fans.
I also wish that the fans came on earlier, but Dells firmware does not do it. 3rd party software is needed.
On my Voodoo laptop, the fans are variable with the Fn+F2 toggle. Voodoo uses the standard Clevo presets for fans to come on at 55C for the cpu and 65C for the Gpu.

I think overheating is the biggest cause of failure. I had a HD fail in a desktop because one of the fans failed.

I am surprised vendors don't pay more attention to this.

 

You did say you just discovered the fan was not working? I think its obvious you have had a sensor failure or other to kill your fan from coming on automatically, not that Dell should have done that? Have you made any hardware or system changes prior?

I8kfan proved that the fan works, and if it's working from your temperature presets, I would have to say your sensors is working as well.
As you said there is NO reason to have to rely on third party software.

You can do the full internal hardware test by holding down the FN key and POWER on button during boot up. Pay attention to the sensor section.

I use I8kfan to OC my GPU but not during normal use, much quieter and less wear and tear on the fans. You might also use air and a vacuum to ensure your fan port is clear of fuzz.

My first dell came with total fan control failure, I ran the fans with I8kfan till dell killed it during tests three days later Hopefully this hasn't happened to you. Note that you have to add +8C to I8kfan if you want better accuracy.

No hardware or any changes since getting it.

I just discovered the fan just doesn't seem to ever turn on. It seems to run at 60-62C all the time. That's a bit high IMO?

I had to force it on with this 3-party software I8Kfan. Looks like the temp. sensor went bad? I will run the check you suggest.

 

It sounds that you have the integrated Intel GPU with the only fan. This is a big laptop so depending on CPU load, the CPU fan will kick on as needed.

Did you say you were able to set presets? That would mean your sensors are working.

If you determine that sensors are good or bad at lest the dells have a great third party option with I8kfan.

Not sure what you mean by this. I used I8Kfan on both manual and automatic modes, and it turns on the fan once a threshold is met. Does that mean the sensor is working?

 

Sounds like your sensor is working as I8kfan has to know how hot the CPU/GPU in order to cycle fan(s) in Automatic Mode.
