Are the fan in lap top supposed to run always?

Laptop , cooling pad - In order to reduce the lots of heat generated during the long run of laptops, the cooling pads are employed. The cooling pad consists of two -four fans made of plastic (for low weight).They can be operated with the external power source as well as with the power from the laptop itself with the help of USB cable.They plays important role in the reduction of heat and hence to increase the performance of the system

I am not sure about this. My laptop fan is not running continuously. It will run for some time and for some time, it will not run .Because of this, my laptop always burning and I am not able to work. I have also cooling pad to reduce that.,But still the heat is not seems reduced.What is reason for intermittent running of my laptop fan? will there be any problem with the laptop? Is it necessary for the fans to run continuously?Are the fans are meant for continuous running? Please guide me in this. If I call the service engineer without knowing this fact, they may charge more by telling various faults with my laptop.

it's better to have a laptop fan for your laptop and it must be running while you are still using it so that the insides of your laptop be prevented from heating so fast. it's just like a desktop that has it's own fan for the power supply to avoid burning, it's also good to do computer works in a cold place.

Well there are two or three fans inside every one of your laptop. But the third and the second fan run only when the processor emits more heat , or in other words the processor is processing memory intensive operations that require a hell a lot of memory to stay alive. If the third or the second fan runs continuously, then i suggest that you check out your motherboard or your processor fan for any defects. Rajah Ganesh G.S. Certified A+ N+ Professional i@mhErO!

There might be problem in board of your laptop.Speed of fan should be varied according to heat generated by your laptop. It is stopped intermittently means in between it is not gettig power.Thre may be any component faulty on your board which is not working properly.Actual reason cannot find out by just description, it should be checked personally to know exact reason. So just go to repair shop and get it checked. It can be repairable if your region has good technician.YOu should get it done as soon as possible otherwise you would face a big technical problem in your laptop. Have a nice time. Cheers Ranvir

There are lot of possibilities for that also.Because, some of the keys are not working well,(on/off switch and media control switches) Also the battery is not getting the power continuously it seems.That's why its giving the back up power for 20 minutes or 40 minutes like that. If we try to change the board of the laptop, then they will charge too much and for that much of amount, we can buy one more laptop..Now I have to call the authorized person to check all these things.Thanks for your response.

YOur laptop is suffering from lots of problems. If you go to customer care of laptop then they will charge more than you expect. so here you can buy another laptop. Just take back up of your important files.If in your country repairing charge is more then it is better to buy new one. I am very grateful to you for your comment on my response. I like your type of attitude to give comment on response. Have a nice time.

Yes. After seeing the responses only I noticed that one. The fans are always running , but at lower speed. And also it should run at higher speed when the temperature of the processor is more. But my fans are running at high speed only in rare case even if the temperature is more. I am not able to keep my hand beside the keyboard to type anything for more that 10 minutes. Even if I have the cool pad, enormous heat is generated.I need to run my ceiling fan also to reduce the heat.Then only I am able to work and it seems my laptop is supposed to work in the air conditioned environment only. But in my home I don't have air conditioner. I should take this laptop to the service center.Thanks for the response

hello nice to meet you, my opinion about laptop fan is this hardware is very useful to make our laptop not over heat, but you not running your lap top continuously, so you should not turn on your fan, because base on my experience if you use laptop for about 2-3 hours do not use fan it will make noisy sound like "ngiiiinnnnng" it will disturb you. any way your laptop always burning it make you disable to work, i handle this problem by using desk fan, i am not lying, it really works, i place my desk fan near my laptop, the fan should directed at ventilation of your laptop, so it will make a better air circulation, i hope my suggestion can help you, sorry for my bad english

Nowadays,I am using one laptop cool pad always..But the cool pads are not reducing the heat of the system on the top of the laptop where is also the heat is generated. TO avoid this I used to keep my lap top under the ceiling fan also for about 10 minutes once in two hours at least.The heat available at the bottom seems to be transferred to the top by the cool pad fans.That's why the top of the lap top is also hot always. If we don;t use the cool pad, the top surface is not that much hot. But still the fan inside the lap top used to run now and then at higher speed..Thanks for your response

i think most of the time while your laptop is running your fan must run so that it can just make the processor of your laptop cool. i will also recommend you not to manipulate directly or indirectly the functioning of the fan in your system . it is a very need equipment which make your laptop cool and long running

Yes.Now I noticed that after seeing the responses. The fan is always running , but at lower speed. It is supposed to run at higher speed when the processor become hot. But mine seems not working well even at the high temperature and it used to run at per its wish. Soon after the use of 15-20 minutes, the laptop become like a furnace and not able to work with it due to excessive heat. I think that I need to spend money for this.Thanks for your response.

This happened with my friend's laptop. I think that the fan is constantly spinning but when things start heating up a little then the speed of the fan increases in order to cool the inside of the laptop down and this is probably what you can hear. I know for sure that desktop fans have to run continuously. It may be slight different for laptop fans, sorry not much help. I don't think you have any problems though. Andrew

Of course..We are able to see that the fans are continuously running with the slow speed and if the system is getting hot, then they start to run at higher speed. But mine is running now and then only at higher speed and no heat seems to be dissipated.My laptop is always like a electric stove.Not able to work peacefully.Highly irritating me.I should call some technical person and should check it. Else it may create more problems in future.Thanks for the participation in the discussion.

Excessive heat on your laptop will shorten the life of your battery if not fry your board so you should have your laptop check by an authorized technician immediately before a more severe problem comes out,using a laptop cooler is your best solution for the mean time but I think is not enough to cool down excessive heat.

Of course. My battery is not giving charge for not more than 20 minutes if the power is not available. I used thought the reason is its continuous use and years of use. Now I am able to know that the excessive heat is also the cause for the short life of the battery, It seems this is the time to call a technician. Though I am using a cooling pad, I don;t get much result for that as the fan inside the laptop is sending the hot air outside. But the cooling pad fan is sending the air from outside to the inner of the laptop and both are doing these works through the same ventilator.Thanks for the useful hint.

I bave been using a laptop for a long time and I notice this is well. At first I think something might be going wrong but my fears are more perceived than real. Fans are not designed to run continuously, they dissipate heat as soon as it reaches a tolerable level. It is normal to feel the heat especially in high end laptops with advanced systems. We might think that they are getting too hot when in fact the heat in withing acceptable level. During hot weather, the heat emitted is intensified and we should see to it that air vents are not blocked, that is dangerous for the laptop. But if what you mean by burning is actually burning, then definitely it's time for you to go to a service center. enjoy

I have one more lap top in my home in the same make(hp) and that is not getting that much of heat. I am not able to keep my hands for typing on the laptop continuously for more than 5 minutes.Then I have to get back my arms.That much of heat is produced and only for few minutes, the fan is running now and then.I can not even touch the back of the hard disk panel after working with the laptop fro about half an hour. Am I need to change the hard disk or the fan?confusing ..Only the technical person can decide this.Thanks for your response.

Depending on the airflow your computer gets to cool itself down,it will run the fan to expel what excess heat there is inside the casing..Do you sit with the computer actually on your lap,or do you sit at a desk while Using it? As you could imagine (and probably feel while using it!) the computer warms up on your legs,as you're partly blocking some air vents,thus reducing airflow and causing the fans to work more..keep Your computer dust free,and try and work in an airy place with some airflow to help..good Luck!

Some times, I used to work with the laptop by keeping it in my legs. But I can do so far more than 10 minutes. due to the overheat. But now I have the doubt of the ventilation slots might have been blocked by some external particles or dust. I should clean it first.Even after doing so, if the system gets over heat, then I need to call the technical person to look after that. Else my hard disk may fail at any moment and can cause more expenditure.Thanks for responding to this discussion.

Sounds like it is over heating and constantly haveing cool itself off. This is not a good sign. Do you have a lot of papers and debri around it. If some that might be contributing to the problem, humidity can do that too. I would call customer service and see what they suggest for you too do. Sometimes it is harmless but if it is doing it all the time that can not be good.

The working environment of mine is neat and I will clean everything very often, at least twice in a day. But I did not see if there any blockage in the vetilation slots of the laptop and some of the members are saying that could also be one of the problems. As I am not familiar with the hardware, I have some hesitation to open the back of the laptop. It seems that I have to call a technician and ask him to check the laptop. But as the time is not permitting me to do so, so far I failed to do that. Now I have to do very soon.Thanks for your participation in this discussion.;

Hope to have it right. In your bios, there one feature there that monitors the temperature of your CPU's. Its the same in principle as the thermocouple on our air conditioners and refrigerators. When it senses that your CPU is on its critical level, the fan starts to blow and then automatically stops at certain temperature. Same with out air conditioner, when the thermocouple senses that the room temperature is dropping below its settings, the compressor begins to pump and cools the surroundings. Same happens to our refrigerators. So automatic start and stop of our fan is just a way of controlling the temperature of our CPU's not to overheat or damage the critical parts inside it.

If this the case, then there may be the problems in the heat sensing element in the system or there may be some settings to adjust the minimum temperature at which the fans are supposed to run. My fans are running only if the hard disk much hot or when I am working with more applications.If the problems are only with the settings, then there will not be any problem in the adjustments and no need of spending money. If some other problems are there, I have to call the technician I think.Thanks for your response.

Wow I have a similar problem with the overheating part .I run my laptop all the time and I think I can always hear the run running but there are times when I hear the fan running extremely hard .I think it should run continuously especially if it is working all the time because electronic components deliver a lot o fheat when working

Mine is also working for more than 18-20 hours in a day. But the fan is running fast only for few times and then the system start to perform slowly.Then I need to keep the laptop in the standby mode for bout 10 minutes at least.Then only it is working fine for about one or one and half an hour.This is happening repeatedly.Still I believe some problems may be there in the hard disk as some of my friends are saying that the hard disk should not get such a heat.I have to call a technician it seems.Thanks for responding to this discussion.

Hello, Wordlinx! Well, maybe there is a problem on its fan because it must run at least on low speed when you use your laptop and it runs in high speed when you do things that can make the processor heat up faster such as games. You can go to a technician for a repair or replacement of the fan. You can also try staying on an air conditioned room when using your laptop. That was a similar thing done to a desktop when its fan was removed. Have a nice day!

So far I used to think the fan is running only when it makes a reasonable noise. Only after seeing the responses, I looked back of the my laptop and check for the run of fan. Still it is running, but at slower speed as you have mentioned.Thanks for the technical information. But friends are saying that there may be some problem with the hard disk itself and that's why it is getting that much of hot.But I don't have any other problem with the laptop except the overheating and system hang because of overhear. But I have to call a technician very soon.Thanks for your reply.

Hello there! I think you need to set up the fan settings in bios mode. And if the problem persist bring it to the expert, your laptop blower has problem and maybe you need to replace it. The fan inside your laptop is for the cooling of your processor it needs to run continuously to prevent burnout. I had a the same problem with my laptop, I made my own laptop cooler powered by an external power supply I think this is more powerful than the usb one. But I think it need some replacement. I hope I can I help you with this info. God Bless!

As I am not having much experience with the BIOS set up and configuration, I have to call an expert only to check the settings, as you have mentioned. If I keep my hands on the hard disk while it is hot, I can not keep for more than 3 seconds. It is the abnormal heat and I have never experienced with any t others laptop so far. I think I need to change my working attitude and should avoid multitasking.From the previous response, it seems multitasking is also one of the reasons for over heating of the laptops.Thanks for the guidance.

Hi wordlinx well fans are not supposed to run at full speed always, you hear the fan mostly when they are running high and they only run faster when the laptop gets heated, happens also with mine, good for you though, coz you are using a laptop cooler, i think even i should get one... check your vents for any kind of blockage, these aren't good for the laptop in any way... i guess the computer gets heated more when you happen to do more multi-tasking and playing games, well playing games certainly is going to make your fan buzz high and getting heated... yeah but check for this, when your fan isn't running fast your laptop should not be heated, coz fan only runs fast when your computer is getting heated, if your laptop is getting hot and you can't hear the fan then you could be having a problem... have a nice day wordlinx!

Now I am able to understand the happening. My fan will start running with a noise some time and if I check the bottom of the laptop, mostly it will be very hot. If I put the laptop in the standby more for about 10 minutes, then it will become normal and I will not heat the fan sound. I am not playing any games in my laptop. But I used work with two or three applications simultaneously and also my browser window will be having multiple tabs always.This can be also a reason for that. Is it so?Thanks for the detailed clarification to my doubts.
