Sleep now leaves CPU fan on

April 11, 2011 at 10:26:11
Specs: Windows 7, Intel E8400
Sleep puts monitor in sleep mode and shuts down PC - except for CPU fan. Before the fan stopped. Reset BIOS to default. Power mode is set to never sleep. Same as before. Win 7 is the 1st Win (Win95 - Win98SR - WinMe - WinXP x2 - Vista -->Win7) to even work in sleep. (WAS)

are your fans running from the mobo fan connections?
if they run from direct power connections the only way you can shut the fan off is to put a switch on the fan, but you have to remember to turn it back on again..

Thanks for reply ...


CPU Fan is plugged into MOBO. Has turned off in past. Temperatures seem OK.

***CPU is overclocked ONLY using BIOS -- ASUS % at 30% So it's running at 3601GHz

# Setting BIOS to default actually lowers CPU to about 2400 and jumps to peak at 3600 ????? You can set it permanent to 3600 if you bump all voltages instead of auto.

Maybe shows sys only needs 2400, not even 3000, let alone 3600 unless stressed!!!!!!

just reread this, if your power mode is set to never sleep how is it going into to sleep?

do you have both win 7 and the manufacturers sleep modes in operation?
one may be interfering with the other.
also check your device manager, and power options on individual devices, they may be interfering with the mobo shutting down completely..

"...if your power mode is set to never sleep how is it going into to sleep?..."

Well power settings are to save power as I see it. Save on your electric bill by shutting down your monitor in 5 - 15- 30 min etc and you can set the PC to a different time if you expect background programs to run.

Like, I go and buy my lunch every day and it takes 25 min, but I like to get coffee at separate times (7-8min) and I set defrag to run at 12 noon.

So I need to set my monitor to shut down at 10 min - not while I am getting coffee, but while I am getting lunch.

But I need to leave the PC on because defrag is timed to run. So I set PC shutdown at 35 mins.
------------------

However whether I choose to just leave all on - never shut down - burning power while at lunch or set shutdown times the --> Start ---> Sleep button overrides everything and FORCES Sleep Now.

Is that not correct?

What we need to know is how MS programmed Sleep and why is the MOBO connected fan to the Intel PCU now not working.

Only changes are MS auto updates, security def and ati graphic drivers.

--------------------


I will try setting a PC sleep time though. Think I did before but didn't make any dif.

In the BIOS there is |

CPU Fan Speed (RPM) [xxxxRPM] or [N/A or [Ignored]

&

CPU Q-Fan Control [Disabled -(default)] [Enabled]

There's a Chassis Fan also, but I have no other fans --> side is removed from case for cooling. :-) [Why I can see the CPU fan.]
________________________________________________________________
*I don't suppose it would hurt (expense wise) to leave the CPU Fan on permantly.
________________________________________________________________

I just got 14 (yes 14) MS updates come down. I mean who knows, something got crossed with the fan. If no one else has it - it must be my fault.
