Tried cleaning my cooling fans out last night... including the one over the pentium chip... now I put it back and botht of the fans are constatnly running on high speed it seems, and Im afraid to keep running my computer this way...

This isn't a motherboard question.

Are you sure you gave us the right model number? My system doesn't show it and neither does the SearsPartsDirect web site. It shoulds like the switch is bad, but it could also be the thermostat if it is a thermatically controlled fan. The hardest thing in replacing a switch is getting to it and then putting everything back together correctly. Suggest taking digital photos on each step of disassemble process so that you can refer to it when you go to putting it back together.

Turn the computer off.
Remove the side-panel, to expose the motherboard.
Turn the computer on.
When you see PRESS <blah> TO ENTER BIOS SETUP, press the <blah> key.
Use the "arrow" keys to move around the BIOS SETUP menu,
looking for any "system health" menu-entry.
Press the "enter" key to select that menu-entry.
It should report the current motherboard temperature, and the current CPU temperature,
and the temperature-limit, beyond which the motherboard will force a shutdown.
It may also report the speed of the power-supply fan, the case fan (if installed), and the CPU fan.
Also, take a look at the fans, to confirm that they are spinning.
Replace any non-functioning fans.

kindly clean the ram and if there is more then 1 ram in motherboard removed that and try installing with single ram. also check the fan is working fine and .the heatsink in not too heat. chek the media cd also .

Hope this helps. Please rate my response.
Thanks.
Have a good day

I would never disconnect a cooling fan , overheating fries chips. Find a cooler place to stand your machine lots of space around it and near the flooor, if that doesnt work. remove the fan and clean it thoroughly especially the blades, then clean the air vents to your device.

Some fans are controlled by temperature-sensitive sensors.
So, if the motherboard is "cool enough", the speed of the fan will be reduced to "zero".

Sometimes, a motherboard can enter "standby" mode.
This mode consumes only a small amount of power;
and the fan will be stopped, because the cooling it provides is not needed.

I personally had this model for about a year. It was one of the last laptops to have actual Pentium 4 processors put in it. They create a ton of heat and the heatsink design will clog just like the lint catcher in your dryer. Try this:

1. Take out of the battery and remove the AC Adapter
2. Flip the laptop upside down and locate the two fans towards the back corner.
3. Using an air compressor, shortly shoot air into those fans shooting towards the back of the laptop. (can of air is never strong enough)
4. You should see dust and **** fly out the back.

Note: this is not generally very good for your fans so try not to overkill them. You can keep your laptop in clean areas and even use one of those cooling pads but you will still get dust to stack up inside. I personally did this to my laptop every 2-3 months to keep it clean.

actually hp DV series have over heating problem after some time the cooling fan on the back of laptop gets weak, try to service the fan on the back of laptopwhile switched off with an air blower used to clean out dust see if it works other wise i think the fan motor has got weak it also gets noisy by time try replacing the fan or get it replaced

pls do rate me

Clean the cooling fans, specifically the lamp cooling fan located inside the rear cover, above the optical blocker. This is easily blocked with dust and causes overheating of lamps/shortened life.

I think I found the problem.

unplug humidifer, remove top tank, empty all water out of base. dry off.

turn unit upside down.

unscrew five visible screws.

use a screw driver to pull off the black foam foot pads. you will find more screws there.

pull off the base.

look next to the fan, you will see a metal "tower" going up into the reservoir. Is it dirty such as white chalky substance on it? Clean it with cotton swabs. Clean the fan while your at it if needed.

You will see a small gray box with two metal tabs twisted. Untwist them and pull off the top.

On that metal "tower" you will see a small black chip connected to the circuit board where you just removed the metal top. Does black chip have black marks on the circuit board? Mine does. I suspect the "tower" which draws heat from this black chip was no longer able to cool because of the white chalk buildup on the tower, furthermore, the chip became too hot and caused the black chip to overheat (again black marks on the circuit board).

The chip has on it "FTR 02N" and a "54F" at the bottom. I tried doing some basic searching on internet to see if it could be replaced, but didn't find anything.


For those who don't have this problem yet, just keep that metal cooling tower clean.
