Question about HP Computer System Cooling

2 Answers

(1) How do I turn off the computer fan from surging?

The surging is sporaic but once it starts it continues for 10+ minutes or more. Not sure what causes it to start or stop.

Other concern is that the computer appears to be constantgly running. How do I figure out what is running and limit these actions?

As far as the fan issue goes, especially if it's a laptop, blow out the fan exhaust area. Use compressed air to blow out the ventilation area in the opposite direction that air flows through it normally. You'll be amazed how much dust comes out. You can try one of those crappy over-priced ridiculously low pressure canned air deals but to really get it clean, find someone with an air compressor. A mechanic friend or someone in construction that uses an air nailer maybe? If it's a desktop, try blowing out the processor heat sink preferably with the fan removed. Be careful, start at lower pressure and slowly work your way up. Also, if you take the fan off of the heat sink, be careful not to knock the heat sink off of the processor or you will need to clean both surfaces (heat sink and processor), reapply a thin layer of heat sink grease, and reinstall the heat sink and fan assembly. I'll leave the second half of you question open incase both issues are one-in-the-same.

Replace the fan! The bearings are starting to dry out and that's when it will surge.

The other concern is a little more difficult from your explanation. Try this, open the task manager byt pressing ctrl+alt+del. When the window pops up, left click on Task Manager. Click on the Processes tab at the top of the window. Now click twice on the CPU column to sort the processes so that the highest number is at the top. That will show you which processes are using the most of the CPU time.

Hope this helps.

What does the fan look like for HP m7680n i need to replace it. at boot msg, fan failed press F2 to continue etc.


  • With the power off open the case. Generally it is the left panel that will slide off after you remove the screws in the back.
  • You will see the fan setting on top of the CPU heat sink.
  • Turn on the computer. That fan should run.
  • If not, turn off the computer, remove the fan and take it to a mom & pop computer store and ask for a replacement. Shouldn't be very expensive.
  • If you don't feel comfortable do what I suggest, take the tower to a mom & pop computer store and they can do it. There might be a minimal charge in addition to the fan.

I would not run the system very long (minutes) until the fan problem is resolved as you can over heat the CPU and ruin it.
I do this for fun & 4 thumbs not for $$$$

My compaq presario become very hot within few miniute and then it is automatically shut down.what is its harm and how this problem can be solve.


It is overheating. It may be a few things, check the vents and make sure they are not blocked by anything (sometimes dust can block them as well). Also listen and feel at the vents to make sure you fell air blowing out (if not the fans may have died out).
The fact that it shut down means it is trying to save the components before they burn out. You should be able to turn it back on once it cools down enough. You can also use a fan to blow air through the vents to speed the process. If it continues to shut down, it will burn out eventually if not repaired. You can get by for a while by using a fan base (you sit the laptop on it and it has fans blowing air on it to keep it cool). You can purchase this at any bestbuy or staples.

Heres the summary Had a problem with over heating... Cleaned out the fan... put the cover back on and now the fan wont turn on at all. I also get continuous beeping when I start up the laptop but by...


the beeps are post during post the very first work is done by the ram,all the memory in the ram is first transferred to the hard disk,and remains active untill turned off.

make sure that your RAM is securely seated

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them they could be faulty

a computer needs its connections to continue its cycle and to have and end to function
obvisously the beeps are windows searching for some hardware it could be RAM cd/dvd hard drive or motherboard all of these must have secure connections for the computer to work
make sure all leads that are attached to your drives dvd\cd have secure make sure the connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error
hope this helps

How to replace my dell inspirion 1525 cooling fan


Depending on the side of the fan you look online to the right size before you buy. Once you Have everything prepared the First thing you do is make sure that you are grounded from any static and fully discharged from your body (Of course turn the comuter off also). Next you can unplug the old fan from your motherboard, you can find it easy as a small cord running from the fan itself. Remove the old fan or the whole cooler itself. once you do that, simply reverse the process using the new fan that you purchased and your computer will be good to go!

Sounds like the fan is wearing out, as it heats up the fan needs to spin faster and if the bearings are wearing out it will start getting louder and it will also get hotter because the fan cannot keep up the heat being produced. You can replace the fan, most computer shops will carry replacements, also get a can of compressed air and give the inside of the computer a good cleaning. This will help keep things cooler as well. Also make sure that the air vents on the outside of the case are clear as well.

If the fan is clanking/clicking it needs to be replaced, a whine is an indication that the fan will be failing soon and will need to be replaced.
In general if the fans are spinning really fast it means that the system is getting hot and needs cooling. make sure to clean out your system regularly. http://www.pctechbytes.com/DIY/maintenance.htm
You may need to get another fan or two to install in the system to increase air flow, or move the system to a better ventilated area.

When i turn the computer on it starts then


SOS beeps are post codes the computer sends to alert you of problems detected during start up.

The beeps can mean anything from over heating to bad memory detected. Find out what your Motherboard bio is and check Here. This has a handy beep code listing for many of the common mother boards.
Good luck!
