Fan loud when turning on Dell e1505 in Cold weather

I have a Dell e1505 from 2006. I'm also in Ohio where it's freezing right now.

Since my heater is not working right now, my home is really cold. Whenever I turn on my laptop, the fan turns on and it's rather loud. After a few seconds, it goes off and my computer is just fine.

Perhaps this could be that my PC is just a little bit too cold?

In one occasion, the fan didn't stop running even though the OS has already loaded, so I had to turn off and restart the PC.

Hopefully it's nothing but the cold temperature, but I'm backing up my files to be safe

 

The initial fan startup is a bit forceful on both my laptop and my desktop, settles down after a bout a second. Normal for me, I wouldn't worry. Use HWMonitor from CPUID to verify your temps are ok.

 

Based on my sense of touch, my laptop is really cold when booting up. The air from the fan when it turns on is really cold.

What's the optimal temperature for booting up?

 

I would say, in general, 40-60C is a good standard temp. I would speculate the fan is a bit strong at first to whisk away any abnormally high startup heat. Just guessing, but as long as the air is not unbearable, you are cool

 

Yeah it's pretty normal in many laptops, i used to have a HP compaqnc6400 and use to do that all the time

 

I guess I could buy a space heater and heat the up computer a tad bit so my PC would boot in normal temperature.

 

It happened again tonight.

The room was cold and when I turned on the laptop, the fan was going crazy! Plus it slowed my PC to a halt. I had to force it to shut down and restart again. The air coming of the fan was really cold.

Could this be because of the cold temperatures or my aging hardware. The room temperature was around 52 degrees F

 

It does it as a test to make sure the fan is working properly. It puts it to full blast powerwise and measures the rpms. It then also uses this to calibrate it as to how fast it should spin.

 

no, 52F is an awesome temp to running a laptop. Can you upload a video/audio clip of this fan issue. I am having issues understanding exactly what it is like. I notice a quick, high velocity push at startup, but it always subsides.

 

The only thing I can think is the older bearing in the fan might not like the cold(er) weather.

 

This is a "problem" that's quite frequent with computer fans in general.
Back in High School, I used to help my friend (out in the sticks) host computer gaming LANS on the second floor of his External Garage, and as you might have inferred, it gets pretty cold there (Northern IL shouldn't be too different from Ohio).

So I would often fire mine up to that wondrous "RRRRRAAAAAANNNNNANNNNANNNNAANNNGGGG" sound whenever it was below 40 or so outside.

I'm guessing it's caused by vibration since all the parts of the fan proper aren't made of the same stuff (the pin is some cheap metal while the blades are ceramic). So some part might contract more than the rest of the unit.
Oncel the temperature causes it to expand again, it has a tiny bit of wiggle room, and it's spinning quite rapidly in a metal box, ergo, the noise.

I've never seen one break or otherwise damage a computer because of this.
