Laptop cooler fans reduce the device's operating temperature which both limits heat exposure to the hardware and makes the device itself more comfortable to use. Laptops include built-in cooling fans and can be placed on notebook cooler pads to reduce operating temperature. Prolonged heat exposure and component overheating can damage a computer's components over time, whereas extreme overheating can actually break the system. Laptops have limited space to work with for cooling, which makes the cooling fans vital to the device's well-being. Faster CPU and GPU PerformanceInternal laptop fans support faster speeds; however, the fans themselves don't make the computer faster. Laptops often employ an internal system fan that's connected to the Central Processing Unit and Graphics Processing Unit heat sink. The CPU and GPU are the two biggest heat producing components inside the laptop: they can produce enough heat without cooling to break themselves. Faster computer hardware tends to produce more heat than slower computer hardware, but both tend to break around the same temperature range.

The internal fan keeps the CPU and GPU from damaging themselves. Lower Ambient TemperatureExternal cooling pads equipped with fans can help keep the laptop's temperature down without requiring any modifications to the device's hardware. Computer operating temperature is affected by the environmental or ambient temperature: the laptop will get hotter working in a room that's 100 degrees versus one that's 70 degrees. Laptops can also be affected by the temperature of the air that accumulates around the device: cooling pads circumvent this problem. A cooling pad uses fans to either blow cooler air against the laptop or warmer air away from the laptop to lower the ambient temperature. Ideal Resting PlacesLaptop cooling pads improve laptop airflow by positioning the system on a hard, flat and non-fabric surface. Some laptops use the bottom of the device as an air-intake source to cool the system which makes obstructing the airflow particularly hazardous for the system. If you're using a laptop cooling pad, you can place the laptop on a fabric surface without worrying about the device overheating.

For example, a laptop that's working on a wooden table will accumulate less heat than one used on a heavy blanket. However, cooling pads that blow cooler air against the system may force more dust into the computer when used on a fabric surface. More Comfortable Lap UseLaptop cooling fans make using a laptop on your lap a more viable experience for both the person and the laptop. Despite being named after laps, laps really aren't the ideal working condition for laptops. Your lap obstructs the laptop's vents and causes the device to build up heat, and laptops without a fan may get too warm for comfortable use on a person's lap.After a year of operation, I got increasingly disturbed by the high noise level of my Lenovo Ideapad Z565. Not sure whether it was that loud all the time, I started to pay more and more attention to the fan. The fan operation is controlled by the second button from the right in the row of system buttons in the upper right corner of the keyboard. The fan control button provides three options:

Even in silent mode, the fan got very noisy. When my system started to turn off without warning under heavy computational load, I observed that the air flow at the fan exit in the rear left corner of the laptop was a gentle breeze of hot air only. It soon became clear that it was by far too gentle to effectively get rid of the heat energy. Finally I decided to have a closer look at the fan itself. The following documents how I accessed the fan of my Lenovo Ideapad Z565. hvac duct cleaning forumBefore dismantling the laptop’s cover, unplug all power supply, remove the battery and check with your warranty conditions! what is best way to clean microfiber couchYou will find detailed instructions in Lenovo’s Ideapad Z560/Z565 Hardware Maintenance Manual in section 1070 on page 41.best way to clean cedar blinds

After removing the fan, the reason for the noisy fan and ineffective cooling soon became clear. A heat conductive copper construction redirects heat energy from the center part of the motherboard to the heat fins, that are placed between the fan and the air outlet of the cooling system. These heat fins are very narrow – too narrow as it was clear by now – and dirt and dust accumulated in the heat fins. These blocked in consequence the air flow and heat energy could not dissipate from the laptop.vacuum cleaners best suction power Cleaning the heat fins and their surroundings with a vacuum cleaner at lowest power removes the dust effectively. best leather cleaner houstonMounting the fan back at its original position with the three screws and fixing the back cover reassembles the laptop. best way to clean and disinfect wood floors

It will be much more silent now and will operate more stable under heavy computational load. The Lenovo Ideapad Z565’s air ventilation system is poor design. The final heat fins are the most narrow part of the pipeline. Dust and dirt accumulate on the way out and prevent a dissipation of the heat energy. A better filtering system at the air inlets would protect the system from pollution and would be easier accessible for maintenance at the same time. Moreover, I was surprised to learn that the noise is not caused by the fan itself but by the air passing through the heat fins.How do I keep my laptop functioning in my dusty room? April 14, 2010   Subscribe How do I keep my awesome new laptop functioning well in my incredibly dusty room?One day, you turn on your laptop. Maybe nothing happens, or maybe you get some error message about fan speed, or maybe you just get a “system halted” message. Then again, perhaps your computer works just fine, but it’s starting to sound like a vacuum cleaner because the fans are running at full blast!

At this point, you may be inclined to freak out. But don’t go there just yet… If this sounds familiar, it’s because you probably read my earlier post, How to Clean the Inside of a Desktop Computer. This edition is specifically for laptops. Usually, cleaning the fan and heat sink inside your laptop is a lot easier than you might think. With a few dollars and a bit of bravery, you can “dust” inside your laptop (without taking it apart, hopefully) even if you don’t know anything about how computers work. If you can dust your house, you can dust your lappy! You will definitely need a can of “compressed air”, otherwise known as an “air duster”, “air squirter”, etc. You can buy them pretty much anywhere, and they look like this: DO NOT use a vacuum cleaner – bad idea (static electricity). Use an air duster! Note: The air duster can will become very cold as you spray. If it seems to run out of gas, put the can somewhere warm and use the 2nd can you bought.

Once the 1st can warms up, it will once again have “spray power”. Right, so that was easy. Now you’re ready to carry on. All laptops have an air input, and an air output. Cool air is sucked in somewhere, and the heated air is expelled somewhere else. Now, if you have some fancy new-fangled laptop, it may have vents that are very well hidden. For example, sometimes manufacturers (especially Fruity ones) hide the vents underneath the keyboard, or they disguise them as a thin and supposedly esthetically-pleasing slot or something. In any case, it is a simple fact that computers produce heat as they run, and all computers must remove that heat from their innards, and channel it elsewhere to avoid overheating and either damage or shutdown. There are some fanless laptops, but they are usually far less powerful than a normal laptop. Usually, they channel heat away from their internal components by using convection (natural air flow – no fan) or by using the the laptop case itself as a heat sink – especially if it’s made from something “fancy” like aluminum.

In any case, if your laptop is making noise, it’s got a fan. And if it’s got a fan, it has vents. So, find the vents on your lappy. The following are some examples of where to find cooling vents on laptops: Well, as you can see, vents can be everywhere! Normally, the one you are most concerned with is the Side Vent, and/or any Rear Vents. You can see which Side or Rear Vent is important because you’ll be able to see a (usually) copper heat sink just inside the vent, like so: The vent with the metal fins inside is the most important one to clean!Now, fire up the laptop. It will probably run much quieter, cooler, and you’ll be a happy camper. I usually do this on my laptop every 6 months or so. If you live in a dusty, smoky, or pet-hair-saturated environment, do it more often.What this probably means is that inside your lappy, you’ve got something like this: Note that in the above photo, all that grey fuzzy stuff is blocking the metal fins of the heat sink.

That means no cooling, which means the fan will spin faster, and thus you have a vacuum cleaner instead of a laptop. In the picture above, the cooling fan should be on the right where the hole in the green board is, but it has been removed. In the following photo, you can see inside another laptop, and the arrows show where to clean with your spray can: Now, if that still doesn’t work, you’ll have to remove the fan to clean the Grey Fuzzies from between the fan and the heatsink. Of course, this level of operation is not for the faint of heart. But, for those of you with some mojo, you’re probably wondering how to open your laptop and clean it out thoroughly without damaging anything. Unfortunately, each lappy is different, and thus you need to find out exactly how to open things up if you want to avoid any major headaches! Just search for something like: There are a ton of videos on this stuff out there, and someone has most certainly already done the hard investigative work for you.
