Go to bios settings by pressing F10 for hp .. there select the optimal factory defaults.and engage and also save settings with F10 ...and exit ..This will get rid of any wrong settings made in bios ..related with he fan ..and should start proper..The only thing that can malfunction is caused by a higher temperature to start ,, and never get to it ..
If it still makes the same should consider changing it ..or see the wires to be proper inserted..cause it has 2 for power and one for starting..and can be damaged..but still functional when you check it ..just the wire for the start to be damaged or not making contact .. ..

SOURCE: HP DV2910us -where to order cpu cooling fan for

Best place to look is ebay. Look it up as a DV2000, as far as I know all the dv2000 series use the same cpu cooling fan. Otherwise, if you have the laptop apart, use the serial number or m/n on the part to look it up on ebay. I do this daily at my computer repair store and have lots of luck with hp laptop fans.

Which way does the rear fan go in a compaq computer tower

The proper installation of a CPU fan is often the subject of debate. Though there are conflicting theories as to which direction the CPU fan should face, there are methods to ascertain which CPU fan installation best suits your needs. The determining factors of your CPU fan installation direction include the manufacturer specifications, your case design and the specific design of your heat sink
Horizontal Installation
  • The installation of a CPU fan horizontally to the plane of the motherboard is the most common installation orientation there is. Your options when installing your CPU fan are to blow cool air onto the heat sink or to pull cool air through the heat sink from the motherboard. Horizontal installations show negligible advantages in either installation direction. The differences in temperature usually vary by only 1 or 2 degrees Celsius. The main point to consider when installing a horizontal CPU fan is the location of the rear exhaust fan on the case. If the rear exhaust fan on the case is parallel to the processor, it is advantageous to have the fan pull cool air from the motherboard and push it out above the heat sink. This is because the case fan will quickly draw that hot air away from the CPU and out of the case, allowing for quick cooling.

Vertical Installation
  • Vertical, or tower, heat sinks rise high enough off the motherboard to allow for a fan to be installed perpendicular to the plane of the motherboard. This allows for cooling to go from the front to the back of the case, as opposed to going from the bottom to the top. Optimal installations for vertical heat sinks are blowing toward either the back or the top of the case. If there is no exhaust fan in the top face of your computer's case, it is more effective to orient your fan on your vertical heat sink so that it blows toward the rear exhaust fan of the case. If there is an exhaust fan on the top face of your computer case, it is almost always more effective to mount your CPU fan so that it blows air up toward the top of your case. The reasoning behind this is that hot air rises and will more naturally flow off the top of your case. Also, top-mounted fans are usually larger and allow for faster airflow out of the case.

Manufacturer Recommendations
  • It is often the case with nonstock heat sinks that the manufacturer has designed the heat sink's fan to be mounted in a limited number of orientations. This is usually evidenced by limited mounting notches on the heat sink itself. Most aftermarket heat sinks use technologies such as heat pipes that have specific cooling needs to operate appropriately. Because of this, it is important that in any CPU fan installation you follow the manufacturer's installation instructions.

Cpu hot

When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

My HP 8710W shuts down when overheated. Usually when playing games. To overcome this, sometimes I let the part of the laptop where the power supply input is located, to stand out of my desk, so that it...

I had similar problem on my HP 8710p and eventually fixed it. Here is how.
First I had a normal overheat situations twice due to clogged dirty fan vents over a period of 4 years. You notice this when the vent cooling fan stays on most of the time, unlike when it was new, even while idling, and of coarse one is reluctant to break open new a PC. After eventually cleaning the fans the problem was resolved but the PC was actually operating at slightly higher average temperatures as the cooling fan would switch on more often that it did when it was new. This is so suttle it did not concern me at the time me until eventually after 18 months, a mere boot would send the cooling fan into frenzy of cooling mode and usually switch the PC off before a full boot could be achieved.(and yes my cooling fins were spotless as I cleaned these once a month at this point).
System reboots were a nightmare as I would have to wait for 30 mins for the CPU to cool down. Eventually I lifted my keyboard on the left side and slipped a small 5 volt fan onto the processor. The fan was powered by a USB port. This worked great but directly cooling the CPU also meant directly depositing dust directly onto the inside of your PC which had to be cleaned with compressed air at least once a week. That was besides the fact that I had to contend with a lop-sided keyboard because of the fan height.
After a year of this I finally I decided to rather try replacing my CPU as I had run out of options. While searching eBay I discovered that CPU cooling apparatus'us were sold in conjunction with CPU's so I decided to buy the cooling apparatus first as a replacement CPU was pricey, especially for an older PC. Skeptical about about my decision, I replaced the CPU cooling apparatus.
To my amazement the problem was solved. Where before I could not even touch the copper tubing near my CPU with my bare finger, now it was cool, probably no more than 30 C and booting was silent. Needing to be sure of this, I replaced the previous cooler and the problem returned, the CPU cooling apparatus copper evaporated spit near the CPU and miraculously cooled down to a room temperature on the fin end.
This was difficult to understand because copper is a very good conductor of heat and here clearly was a situation where the one end of the copper tubing was hot enough to boil spit and the other was at room temperature.

So what can cause this? I am not sure exactly but its not mentioned any where on the Internet as a fix, Not even by HP themselves.
I suspect initial over heating may have messed with the internal climate system in the copper tubing to the extent that the coolant dissipated, probably due to high pressure. The faulty cooling apparatus did not demonstrate any signs of ware and tare, actually the replacement cooling apparatus looked worse than mine as the copper had lost its sheen. I also examined the faulty apparatus from close up for any possible cracks and holes and found nothing visibly wrong. All I had to go on is that the replacement worked and mine did not.
My CPU now peaks at around 50 C when number crunching and the cooling fan is seldom activated. The copper tubing is warm, but not hot, right up to the area where the CPU is located. My system runs so quiet now it has a feeling of newness about it. That raises another question, modern PC's have normally have self preservation software coded into their BIOS that prevents or slows down the CPU clock speeds when over heated or running on battery. The battery part is to conserve power but the heating part is to not do irreparable damage to the CPU. This feature is usually referred to as "dynamic clocking". A hot CPU will run at the slowest possible speed it can function at, (beyond this it will be shut down) at a time when you are trying to crank every bit performance out of it. So it goes without saying my PC now runs faster and appears to be more responsive, just like the day I bought it.
While this occurred to my HP 8710P, I know the problem occurs to many aging laptops that can by fixed the same way. Currently there are many alternative external CPU coolers being sold to solve this problem(and I have seen many and the ones I purchased I have returned). I believe that Trojans and viruses are not always responsible for sluggish PC's. Until you address the real issue, your problem will continue. Consider the above as an option.
My PC was headed for the trash heap. (I am a developer, not a gamer) but now it will stay. Its reliable, trustworthy and never had a problem besides the cooling issue.

My dv9000 locks up after it gets hot. What can I do?

A laptop locks up or shuts down when it get very hot. The CPU shuts down (thermal overload) when it overheats and will not boot up until it has cooled down. If this problem is not fixed, eventually the CPU will fail.
This problem could be caused be a faulty CPU fan and/or the CPU and heat sink assemble is clogged with dust.
Check the CPU fan to see if the fan blade spins freely (it may have a seized bearing), if not replace the fan. If the fan and heatsink is clogged with dust, clean and remove the dust.
If additional cooling is required and there are ventilation grills on the bottom of the laptop, then purchase a laptop cooling pad. Place the laptop on the cooling pad, these pads have fans that direct air into the grills at the bottom of the laptop.

Is my cpu getting to hot my cpu fan runs in high speed a lot. do i need a bigger fan or my cpu is going bad.


Turn the computer off.
If it is a HP laptop, remove the battery.
Disconnect the AC power.

Buy a can of compressed air, and give your computer a "blow-job",
to blow all the dust away from the heat-sink on top of the CPU,
and also, if it is a desktop, from inside the power-supply.

A layer of dust is a layer of insulation, preventing the heat-sink on top of the CPU from "radiating" the heat away from the CPU. So, your motherboard is detecting that your CPU is "too hot", and automatically speeds-up the cooling fan, to try to move the heat.

Compaq Presario 3000 incredibly slow firing up, opening up anything. Loud fan all the time too

This advice relates to the Compaq Presario 3000 Notebook series but may also apply to other notebook computers as well.

The heat sink and fan assembly is probably clogged with dust and airborne particles. The clogged cooling parts can lead to heat problems with the CPU. When the system (CPU) gets to hot, the fan has to kick into high gear to try to cool things down. Once you remove dust and debre from the heat sink fins and fan, you will immediately experience better cooling and less fan usage. Your system may also be set for dynamic switching of CPU speed. If you CPU gets too hot, the system will reduce clock speed and ramp up fan and everything will slow way down. Use a good system monitoring software such as Notebook Hardware Control to monitor your CPU temperature, HDD temp and so forth. When the system starts getting too hot, first look at clogged heat sink fins as possible culprit. If you're good at electronics you may be able to service the unit yourself. Get a copy of the system's Maintenance and Service Manual or have a professional do the job for you as you will have to partially disassemble the computer to clean out the heat sink. Depending on the system, the job can take as little as 15-20 minutes once you become proficient at it.

Laptop switched off while i was working on it

After the notebook shuts down do not turn it back on for 15 minutes and then test it again. Will the notebook work longer if you let it cool down for a while? Isn’t it hot if you touch the bottom? Can you hear the fan running?
Most likely you experience a laptop overheating problem and it would be fixed by cleaning the cooling module – the heat sink and the fan. The notebook processor produces a lot of heat when the notebook is turned on. The cooling module helps to keep the CPU cool when the laptop is working. The cooling module includes two parts: the heat sink and the cooling fan. The heat sink is attached to the CPU and helps to conduct the heat from the processor to the radiator. The cooling fan blows on the radiator and helps to disperse the heat produced by the CPU. The laptop will overheat if the heat sink radiator is clogged with lint and dust or if the cooling fan stopped spinning.
If your laptop shuts down after some time without any reason and warning, check if the cooling fan spins. Usually it makes some noise and you can hear it. If the fan works fine, then check if the heatsink is clogged. In some cases you can clean the heat sink with compressed air, just blow inside the fan openings on the laptop bottom. If the heatsink is completely clogged, then it is necessary to remove the heatsink for cleaning.
