When I came down this morning the cooling fans in my computer were running.
I shut the computer down yesterday and it was totally off when I went to bed.
The computer had not rebooted or anything.

Probably some setting I can't find.
The computer is a few weeks old and it's never done this before as far as I know.

Some specs:

Case: Cooler Master Mystique
Motherboard: ASUSTeK Computer INC. Model P5LD2-VM DH
CPU: Intel® Pentium® D CPU 3.20GHz
CPU Clock 3200.43
System Bus Clock 800.11
System Clock 200.03
Multiplier 16.00
Original Clock 3200.00
Original Bus Clock 800.00
Original System Clock 200.00
Original Multiplier 16.00
Overclock 0.01%

01-Metallica-[Cooling Fans came with power off] 31st MAR-2007

When I came down this morning the cooling fans in my computer were running.
I shut the computer down yesterday and it was totally off when I went to bed.
The computer had not rebooted or anything.

Probably some setting I can't find.
The computer is a few weeks old and it's never done this before as far as I know.


That’s COOL

First –
Was it warm – last night? or have a Thunderstorm? -

Second – When you turn your PC off – Do you just shut down windows or do you actually turn the Main AC Power off – by either turning the – Rear Master Power Switch OFF – or by shutting down a – Power Surge Power Strip – so that the AC Power is removed?

If the AC power is still ON – the PC is just sitting idle with – +5 VDC Standby Power – So a power Surge could set the fans on – The switch in front is called Power ON, but it is only controlling the Motherboard – Not the Power Input to the Power Supply – Years ago – Yeah – It used to be wired to the AC Power IN to the Power Supply – but not anymore -

BUT –

If the AC Power was removed – And the fact that the PC is only a few weeks old – It is possible to have the – Rear Main Power Switch – wired wrong – so that Standby Power is still ON – or perhaps the switch was not toggled completely/properly to the OFF Position –

OR –

Might also be – House Wiring Problem – If the Hot & Neutral are reversed – Is this a new/replaced power receptacle? Or it could be a Faulty Power Strip or Power Switch –

Tell me how you turn PC ON & OFF – including the Main AC Power in
Tell me how you have PC connected – to AC Power .
Are you using more than 1 AC Power receptacle in the room?
Is the PC connected in an AC Line with a Motor or Compressor?
Has the room recently been improved/repaired?

Ohhhhh or is it - - -

I see you are in the Netherlands – Is it my tomorrow already – APRIL FOOLS???

- I used normal "Turn Off Computer" like I always do.
- The AC power is still ON with – +5 VDC Standby Power
- We are not having a heatwave over here. Room temperature was about 16 ΊC (61 ΊF)
(Can they be set to start at a too low temperature? And, if so, where?)
- The fans were not blowing in the wind :whistling:, they have LEDs connected which were on as well.
- It is not an april fools joke.

Sorry – I was just joshing with you -
_____________________________________________________________

I am from the - old school – I define Off as – Completely OFF- No AC Power –

You leave your OS define Off – 3 Standby – Hibernate – Off -??-

I guess Power Management would be the 1st place to check – You have new PC & New OS – so hard to tell what your PC is set at? Whatever the PC Tech set for you?? So Off could be – Maybe – Kind of –

You also have some new factors in this equation – New Cooling technology – S.M.A.R.T. – Self-Monitoring Analysis & Reporting Technology used by Hard Disks – that can cause issues with monitoring utility programs – such as PC Probe – Speedfan – PC Monitor –
_______________________________________________________________

Probably some setting I can't find.


I was just shooting from the hip – just to shake some idea loose. But My may concern was if the fans came on when the AC Power was – thought – to be removed –

Hi Jack123,

I made a screenshot of my Power Schemes tab. Looks OK to me.

Bad news is that it did the same thing again. Turned on the fans with no apparant reason.
If they would stay on after I Shut Down (the OS) I would understand it better, (I guess).

Found some information in the Motherboard user guide that might be related.

Motherboard type: ASUS P5LD2-VM DH

Onboard LED
The motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode.
This is a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component.


I checked and that LED is on after I shut down from Windows.
What the manual doesn't say is how to turn if off fully (without unplugging the power cable). :whistling:

You mean the standard issue 0 - 1 powerswitch? Yes there is.
But no Voltage selector if that's what you mean.

or turn off the surge protector

Pulling the plug is easier and would have the same effect, or... ?

Thanks for your time,

Pieter

yeah...i was talking aobut the switch...not the voltage selector...that switch turns your PSU off...and thereby turns the fans off..

i find it easier to flip a switch than unplug something...

i have no idea why your fans are still going but....i'd relate this to my bro's usb mouse...it's got this superbright LED in the scroll wheel....and you can turn the PC off completely...but that light stays on no matter what...untill you unplug the pc or turn off the PSU switch...

The way I have set things up it is easier to pull the plug then to switch it off. :whistling:

I wish I could be sure if it has done this all the time or if this started after I changed/installed something.
Can I blame a wireless network-card (USB) ?

i'd blame the dutch government...you know it's their fault...they're probably pushing some virus over the power lines...

if you uninstall the wireless usb doodad and the issue goes away...then yes...yes you can blame it...i'd be more inclined to think that you were always too busy eating chocolate to notice the fans before

You're probably right.

The problem is that the behaviour is without any pattern (that I noticed at least)
I have tried other things and thought they worked, just to be disappointed later on.

But I do need another wireless network card for my old computer anyway, so I'll get a different brand and put it in the new one to see if it helps.
Having had problems with this one before, but they are the ones my provider recommends and supports.

We don’t issue the Dutch any of those – Firework Switches -

Take a peek at the Motherboard Fan Connectors – Are they 4-pin connectors?

Probably is an USB mouse & is probably has Mouse USB pwr jumper set to Standby – to wakeup PC & turn On –

Anyway – it makes a good nightlight -
