When your fan comes on, is it on fast or medium speed?

There are programs out there that will monitor your temperatures and the fan speed; check out HW Monitor. Report back with the data. Laptop fans are meant to run more often because of the limited air flow possible in a very small internal space.

Yes, I do have HWMonitor.

Hardware monitor ACPI
 Temperature 0 27°C (80°F) [0xBB8] (TZ00)
 Temperature 1 0°C (32°F) [0xAAC] (TZ01)

Hardware monitor Intel Core i3 350M
 Power 0  25.00 W (Processor)
 Temperature 0 42°C (107°F) [0x30] (Core #0)
 Temperature 2 36°C (96°F) [0x36] (Core #2)

Hardware monitor ST950042 0AS
 Temperature 0 35°C (95°F) [0x23] (Assembly)
 Temperature 2 35°C (95°F) [0x23] (Air Flow)

I have a Dell 6400 and the fan almost never runs, even with many apps open.

I have a 6 month old e-machines laptop T-4400 processor.  I don't think I've even heard its fan.  It is dead silent. (half the cost of my 1558).

The 1558 fan comes on medium I believe.  I don't think I've heard a fast setting.  Only one speed so far.

we need to start bumping each others threads so the fan issue can be fixed.

just received a Vostro 3300.  no fan problem and the hard drive spins down as it should according to advanced power management settings.  Other than the mono speaker, no 1394 port, mic and headphone port placement (and small text resolution due to the 13" screen) - I like it.  It does get a little warm, but doesn't seem to get hot.  The hinge looks like it will hold up better than the studio

I just wanted to update you all. I have the same fan issue on my 1558 (i3, integrated graphics). Even at idle, the fan cycles to high for 30 seconds, then stays at low for 1 minute, then cycles to high for 30 seconds. Super annoying! I went through the same runaround with the dell service techs as well. They came out and replaced my entire motherboard, fan, and heatsink. No change. The fan still cycles. Since they replaced essentially all the internal components related to heat generation, I think this is unfortunately just ill-thought out cooling design. E.g. it's probably as the engineers intended the laptop to run. Of course, they probably weren't thinking about how grating this noise would end up being. Unless there is a bios update which addresses this, I doubt getting a replacement laptop of the same model will help. I also highly doubt my replacement fan and motherboard were faulty. I think this is just how the cooling system is designed. Anyone else been able to eliminate this cycling issue?

When system boards are replaced, the original CPU and heat sink are re-used. When reinstalling the CPU/heatsink, new heat transfer material, paste or pad, needs to be used for both the CPU and GPU chips after the chips and the heat sink are cleaned of old material.. Not doing this correctly is a reason for higher temperatures. Improper installation in the original equipment is also a problem. There is almost NO OTHER reason for high temperatures except for very high CPU/GPU usage by demanding programs. Even the Nvidia GPU chip problem is not a heat generator, but high temperatures and/or temperature cycling actualyl cause the chip to fail.

Same problem here with a Dell Studio 1458 running a Core i5. Fan run's nearly constantly even when first starting up. I haven't found a solution either just thought I would bump this thread up.

I have a Studio 1458 and my fan runs all the time.  I upgraded BIOS to A07 and still no luck.  I talked to technology support and they gave me no help.  I've tried different variables to see if the fan is affected, such as not running any applications, running specific apps one at a time, removing the battery to prevent charging capability.  The fan continued to run from medium to high at all times.

You should download a temperature monitoring program (such as HWMonitor) and follow the temps and fan speeds. It's possible the laptop is actually overheating. Usual reason is dust inside that needs to be cleaned out. Other reasons relate to the heat sink and heat transfer. The heat sink(s) may not be correctly attached to the CPU/GPU, or heat transfer paste/pads are not correctly applied.

I am running HW Monitor (see above).  My Dell 6400 is about 5 years old and has never been cleaned and is in a fairly dusty environment (also with cats around) and runs cool and the fan is silent.

This is just a problem with a noisy over-active fan which hardware can't regulate properly due to inappropriate or subpar components, or quality control mfg issues or parts that could be made compatible with a BIOS fix that Dell does not want to address.

There is something we can do? i call today and told to the service guy the problem whit the fan, and he never understood what i was triying to say, because he de only way that the fan cicle transform in a issue is if the laptop turn off or freeze.

I've have two Dell laptops that have the same fan cycle on/off issue. On 5 seconds, off 5 seconds is the usual with both.

Dell XPS L501X 64 bit, Win7, purch 12/2010

Inspiron 1300 PP21L, WinXP, purch 6/2006

 

I never called Dell Support on the issue. Figured it was a high CPU usage program.
