Dell Inspiron 9300 heatsink fan issue

Dell inspiron 9300 win xp pro sp3 ( clean install )
all the original drivers are installed.
The laptop never displayed errors or blue screens,
It has a major issue the heatsink fans (2) are running at full speed all the time non stop,
I tested the Rig with Geek squad MRI boot disk, cpu, mem,etc. And it passed all tests.
I then took the laptop completely apart cleaned everything with compressed air, of course the heatsink fans too,
removed the cpu and applied the artic silver paste, then put the whole thing back together. (correctly)
The Rig booted without a problem,
but the heat sink fans are still running at full speed after all this work.
What can be done to fix this festering pest.
if nothing is done, eventually the fas will burn out.
What can it be

Check the BIOS, the temps controls maybe set for max, should a auto setting which allows the heat to set the fan speed.

Hi Train
I've checked the BIOS for such setting and there is none.
Dell inspiron 9300 1.73 ghz Pentium M
2 gb of pc 5300 of mem,
the BIOs Version is A05- 2005
The clock speed is 800 mhz
speed fan say the Hd temp is 35 c
and the cpu temp is 86 c
I DLed the BIOS from Dell, but I'm unsure of how to do the flash.
I'm afraid to blow the Rig with a unsusseccsfull bios flash,
this laptop is in cosmetically mint condition and it has a 16.5 bright screen.

Got to much Artic silver on the cpu. You only want 3 thousands of a inch for the thickness. and 86C is to hot.

86C is way to high for a mobile CPU. As Train says, there is definitely something wrong there. It's no wonder that the fans are running full speed :eek:

Super and train thx.
I'll take the thing apart again today! And do what has been suggested, when it's done I'll report back.

By the way I don't get your email after a reply is posted.

Some ISPs block forum notifications as spam. It's long been a problem, but there's nothing we can do about it :(

OK I've finished reapplying the artic silver to the CPU heatsink and to the dedicated video card, when I booted up, the fan issue was not resolved, the fan is still running at high speed.
There are a few things I like to mention:
1 When I close the lid the fan is still running for about 30 sec before it goes in standby mode.
2 When I open the lid, before it goes to the desktop, it generate a brief 2 sec massage, it say that the graphic driver could not be loaded and after that thing are normal.
3 Rig's fan are running but air is comming out quite cold.
4 After 20 min or so, when I pass my hand over the keyboard or lift the Rig a bit to sense if it's hot, I find it barely warm.
5 I'm cluthing at straws !!!!
Thx Super and Train.

It has a Intel® Pentium® M processor - So I would expect to be hot like that. Now chech the cpu temps.

1) Did it do that before, or is this entirely new behaviour?

2) That's nothing to be concerned about.

3) You can't tell much from that, you need to check the temps properly. I like this:

HWMonitor

4) Same as 3.

5) Still better than clutching at nothing at all :D

It is behaving exactly as before No change.
I Dled hv monitor and see what it report and post back.
Thx Super!

Here are the specks for temp and CPU:
Hardware monitor ACPI
Temperature 0 86°C (185°F) [0xE03] (THM_)

Processor 1 ID = 0
Number of cores 1 (max 1)
Number of threads 1 (max 1)
Name Intel Pentium M 740.
I'm begging to suspect that it might be a heatsink or processor gone bad, or maybe even both!

Check the voltages that HWMonitor is reporting. I suspect you could have a failed voltage regulator on the motherboard, which would certainly explain those high temps if it is overvolting the CPU.

Super I don't know how to read this or what to compare it to.
here is the HWMonitor report

OK I've finished reapplying the artic silver to the CPU heatsink

---

Did you verify the contact after applying the arctic silver? I would check that the heatsink is making full contact with the processor first.

I usually spread an even coat on the cpu and then put the heatsink down on it. Pull off the heatsink and look for gaps or unevenness. If the heatsink isn't absolutely flush with the cpu, that's the problem. I know it's a laptop, but I've seen where heatpipes get bent and slightly pull the heatsink off once everything is installed.

I'm totally sure the heatsink is firmly and flat on the CPU it's fastened by 4 screws the sequence of fastening is 1-4-3-2.

I'm not seeing anything in HWMonitor referring to CPU Vcore. This is what mine looke like:

Code:

Can you see anything there referring to "Vcore" at all?

No nothing like that,
but I've everest reporting core voltage as v.0.99 it does not elaborate more than that, other than the temp is about the same as what HW Monitor is saying.

I also have a sony vaio vgn-fs640p that have the same exact processor and the voltage is 0.99 as reported my everest.

Super
HWMonitor it doesn't do what you said it does at all.
All that utility does is monitor the temperature of the processor,hdd and battery voltage, that's all.
it does not inform you of the core voltage. I've installed it in couple other laptops and it's the same in all of them!
Thx.

Your laptop does not have a sensor that HWMonitor can read then :( It certainly does monitor voltages when it can, which is how I managed to post mine above.

Still if you reckon you are getting 0.99v, that seems reasonable. Which is starting to make me think that the problem may be a faulty temperature sensor here. Apart from the fans running at full speed is the behaviour of the laptop otherwise normal?

Super.
The laptop isn't running normal at all,
it take forever to install a application for instance MS word took about 40 min !
I don't get blue screen tho.

Software can't fix worn out|broken hardware.

The worn out|broken hardware must be repaired|replaced.

It sounds like the CPU is throttling itself right back then. In which case it definitely is overheating, rather than a false reading from a sensor :(

THB, I'm at a bit of a loss as to what more you can try, other than having yet another go at reseating the HSF.

Super
I've repaired hundreds of laptops this one baffle me a bit, after extensive searching online and your input,
I'm convinced now that the CPU chip is most likely defective, in other posts few years back others head the same exact issue on this laptop model. Dell replaced the CPU and heatsink and that fixed the problem.
Taken that this Rig is a bit old I'm left with two choices give up or e-bay!
Super thank you for your support and advice.

You're very welcome. It's a shame that there wasn't a better outcome, but at least you can say that you gave it your best shot :)

Try pressing the Fn/z which controls the fan speed - I just discovered this on another forum and it fixed my inspiron 9300 where teh fans would run at full speed as soon as I booted it.

bugfixer
Thank you! the fix worked to my amazement the fun totally stopped running, but will it resume cooling the laptop normally when the CPU get a bit hot. I didn't run the rig for a long time to test it fully, (cause I couldn't find the power adapter and the battery was getting too low) I'll run the Rig with the adapter and let you know.

bugfixer
I've found the power adapter and run the laptop, playing a avi movie comverted vob files to avi and run run other stuff, the fun kicked in at low speed just humming, the Rig remained cool, in other words your fix worked it is just fantastic,
Thank you
