SOURCE: HP D530 SFF CHASIS FAN NOT DETECTED

Should be an alarm setting, usually in the bios, for both chassis intrution and fan and cpu warnings. disable it and no error message.
Most likely the fan power is connected to the wrong fan port on the motherboard itself and placing it on the correct port will fix the issue.

SOURCE: Fans run at full speed under normal task.

THE PROBLEM IS THAT THE CPU AND MB AND PSU IS NOT COOLING OFF ENOUGH AND CAUSING THE FAN TO RUN ON HIGH ALL THE TIME, THE PSU MAY NOT HAVE ENOUGH WATTS POWER TO RUN THE CONFIGURATION TO KEEP THE SYSTEM AND HARDWARE TO COOL.

I READ IT IN ONE OF MY PC MAGAZINE, ANOTHER PERSON UPRADED SYSTEM, ADDED SOME OTHER STUFF BUT THE MB AND POWER SUPPLY UNIT DIDNT HAVE ENOUGH WATTS TO SUPPORT BASIC REQUIREMENTS OPERATING THE SYSTEM BASIC NEEDS.
FIND SOFTWARE THAT KEEPS EYE ON HEAT ISSUES, MB, VIDEO CARD, RAM, PS, CPU, CPU COOLERS, NIC CARDS, SOUND CARDS,
ETC.
EACH PART REQUIRES SO MUCH POWER
AND HERE HOW IT BRAKE DOWN FOR EACH COMPONET

MB 20-35+ WATTS
CD ROM 20-25 WATTS
DVD 30-45 WATTS
DISK DRIVE 5 WATTS
HD 5-15 WATTS
STANDARD VIDEO VARD 5-15 WATTS
MEMORY 5 WATTS PER MB

NEW SYSTEMS WITH THE FOLLOWING STUFF IN IT FLOPPY DRIVE,CD-ROM, MB, 16MB RAM, REQUIRES A MIN. 150 WATTS OF POWER.

BUT I KNOW YOU MAY HAVE TOP OF THE LINE VIDEO CARD WITH GGR4 WITH 512MB
MEMORY, 2-8 GIG OF RAM, 23 INCH LCD MONITOR, 2 500GB HD, BLUETOOTH AND WIRELESS NETORK, AND WIFI CAPABILITIES,
NEW DUAL CORE CPU TOP LINE MOTHERBOARD, COOLED VIDEO CARD,RAM COOLER ALSO AND THIS SYSTEM POWER WATTAGE REQUIREMENTS MAYBE SOME WHERE AROUND 400-600 WATT, AND MOST OF THAT IS FOR THE SYSTEM RAM AND THE VIDEO RAM YOU ARE RUNNING
REMEMBER 5 WATTS PER 1 MEGABYTE OF
RAM
IT WILL ADD UP FAST BOY'S AND GAL'S

ROD

PS I HOPE I DIDNT BORE ANYONE,
IT MAY SAVE YOUR SYSTEM FROM BURNING UP.

Why does my fan on my Gateway ZX4931 always run loud?


does it has variable speed feature?, clean the heat dissipator, is clogged with lint and hairs! and always runs @ full speed, also if you're already there, might as well reapply thermal grease to the thermal dissipator.
ALSO, because you will have the fan dismounted, is so cheap you can put a NEW QUALITY fan (or fan dissipator combo) sometimes bearings gets loose and the axle wobbles (because of costs all OEM fans runs on cheap bushings) new aftermarket PRO-fans runs on ball bearings.
did you checked if a loose wire is not touching the fan blades?

I have a variable speed wall switch on my ceiling fan. It is made specifically for fans. Problem is it doesn't work. If the slider is full on the fan spins. If I unadjusted the slider the fan turns...


If the wall switch doesn't have 3 or 4 speeds then it is not a fan control. There are no fan companys that make a variable fan control so that should tell you something.REPLACE IT with a fan control.

Hi, I am a Japanese carpenter. I recently purchaed a SF4000-A and dont understand why it features variable speed control switch. Can someone please teach me how I am supposed to use this feature?


The SF4000a Is a cordless Drywall Gun. Even thought it has variable speeds most people run it full speed and then press and engage the chuck to run the screws in. The variable speed is used more to back out screws in reverse

I have Hp Compaq nc6220 it works on battery with good speed but when i plug in adapter it works very slow


The only thing I can think of that would do that is if the power setting are messed up. There are different levels of power settings you can choose. Normally on the battery it runs the CPU slower, the screen less bright and so on to save power and make the battery last. It almost sounds like the full power mode or the adaptor mode is using the battery or extended power settings.

What you can do is look under control panel for the power settings icon or right click on the battery or the power plug by the clock and then adjust properties. Look for the tab or pull down that says A/C power or Full power or something like that. Then you need to go to the settings section for the cpu and cooling. Those are the two that have to be adjusted together. Depending on the software controlling you will either see a min/max setting or something that says cpu speed. Just adjust the max to 100% or set the cpu to variable. You can set it to max but that runs fast all the time and is noisier than it needs to be as the fans will always be running harder. And double check that the cooling settings are set to variable as well. Once you save or apply the settings your laptop should be much faster. There is a chance there is a setting in the system bios that is set to slow cpu but that is supposed to be over ridden by the windows software.

Anyway thats about the only thing that I can think of that would do this.Once you get the speed sorted out you can use the same panel to tweak the battery portion to run slower and not use as much power. If the cpu is allowed to speed up and down it only uses more power when you run more so it can slow down when its not needed. Think of this just like a car going up and down a hill. Power to go up then coasts down.

Fan on


The CPU fan on the GX280 is a variable speed fan. It only runs as fast as necessary to keep the CPU cool. But the fan also has an rpm sensor built in that regulates it at 3000 rpm. If the sensor is going bad, it senses its running slower than 3000 rpm when its actually running faster and continues to speed up until its wide open. Thus the 'jet engine' sound. Replace the fan and that should do it. If by chance it doesn't, it gets more serious and likely a motherboard problem.

Variable fan, moaning


a variable-speed fan is highly unlikely for this unit. your fan needs to be replaced or serviced with 30W oil on shaft bushings
