I have a emachine t2542 and i need to remove the heatsink and fan to clean the fan. the fan is really bunched up and clogged up with dirt and that is why i think my machine will run for about 2 hours and then shut off. Could you please help me? there are 2 silver arms one on each side of the heat sink but ive tried pulling them up to release them and cant get it to release.

Hi, you have two silver arms, on one side theres like a handle or grip you need tilt it and press down so the clip pops out, do it for both.
once you get the fan off you can clean it but rememer to put on new thermal grease onto the bottom of the fan as it will damage the cpu if you dont when you put it back on, thermal paste will cost about 2-3 pounds or you can buy a new fan for about 12.

dont attempt this without a new fan or thermal paste.

All the best

Asus m32 loud fan


Fan speed does increase for a reason.....heat. Check you BIOS settings and verify that the CPU temp is not getting too high. Desktop computers are dirt magnets. It is common for the CPU heatsink to get clogged with dust and dirt. This will reduce cooling and increase heat, eventually to the point that the fan will speed up. Get some electronic duster (canned air) and blow out the fins on the CPU heatsink. DO NOT remove the heatsink from the CPU. There is a special compound that is on the heatsink surface that allows proper heat transfer from the CPU. Removing the heatsink means that this compound is disturbed and would need replaced. Most users do not have this compound and thus should not remove the heatsink to clean. If the heatsink is so clogged that you cannot get the dirt out with canned air, you may be able to remove the fan from the heatsink, depending on the fan/heatsink design. Then you can use a brush to get into the fins to clean them.

Laptop emachines e725 overheating


Could be simply a blocked CPU vent, clear with a can of compressed air. Make sure Fan is spinning when you power up the PC.

When the fan is spinning place the back of your hand by the Vent you should feel hot air. If you feel cold air the CPU heatsink may need to be reseated with fresh thermal paste. Worst scenario is the Heatsing has Failed and needs replacing.

If the Fan is not spinning it may have failed or a lump of fluff has jammed it

Dell 1537 overheats running Ubuntu


The cooling fan along with the heatsink is probably clogged with dust and dirt, laptop needs to be taken apart fan and heatsink removed and blown out with a can of compressed air, also! the old thermal paste will need to be replaced if hard check processor and heatsink.

Aspire 5315 0verheats and shuts down


The problem is in the cooling fan and heatsink, laptop must be dismantled down to the motherboard level, remove fan and heatsink, use a can of compressed air to blow out the clog of dust and dirt blocking the heatsink ports and cooling fan, next get some rubbing alcohol and a paper towel and clean the thermal grease from the processor and heatsink. Now apply a fresh thin layer of thermal grease to both items and assemble, this will fix most thermal issues.

MY LAPOVERHEATINGTOP GET WAY TO HOT AND THEN SHUTS DOWN


The laptop will need to be taken apart, remove fan and clean with compressed air, remove heatsink unscrew in a diagonal fashion a bit at a time and remove from processor ic, clean all dirt from the clogged ports and finish off with compressed air. Next remove thermal grease from processor and heatsink with rubbing alcohol and paper towel, now apply fresh thermal grease to the ic and heatsink "not to much" and spread evenly and assemble.

E Machine T3120 overheating


99% probability of one of these two issues:

1. The CPU fan/heatsink assembly clogged with dirt (and the rest of the unit is probably filthy too).

2. The CPU fan has quit working.

To fix #1, get a can of compressed air (the stuff for cleaning PCs) and b,ow out the unit. DO NOT REMOVE ANYTHING from the motherboard to clean it.

To fix #2, you need a new CPU fan. You can get them from any computer parts retailer.

Getting a no signal input on monitor on an emachine w3118 what would cause this


Several things xopunkyxox.

No Signal means there is no Video Signal coming from the computer. The monitor is working fine.

eMachines computers are budget computers. This means they sell for a low price, but also have low quality hardware components used inside the computer.

There are two top issues for computer failure. These really affect an eMachines computer.

1) Power Supply
The PSU (Power Supply Unit) used is a low quality unit to begin with, in an eMachines.

2) Dirty computer.
Dirt, dust, etc., can bring a computer down to it's knees.

The eMachines W3118 desktop computer uses an FIC K8MC51G motherboard.
(First International Computers, inc)

(The eMachines W3118 desktop computer is a North American model)

FIC K8MC51G Specifications:

http://support.gateway.com/s/MOTHERBD/FIC/105554/105554sp25.shtml

http://www.fic.com.tw/product/motherboard/AMD/K8MC51G.aspx

The eMachines W3118 motherboard has a Socket 754 processor socket.
Comes with an AMD Sempron 3100+ processor.
(1.8GHz)

AMD processors run HOT. Keep the Heatsink, and Fan on top of the processor, CLEAN.
The Thermal Compound (Thermal Paste or Thermal Grease) that is in-between the top of the Processor's case, and the bottom of the Heatsink, can dry out over time.
The heat developed by the Processor when operating does this.

A Power Supply (SMPS) has two cooling features.
1) The internal fan that you can see by looking at the back of the Power Supply, (Back of computer)
2) Heatsinks used inside the Power Supply.

Example of an internal view of an average SMPS,

http://en.wikipedia.org/wiki/Switched-mode_power_supply

Click on the photo to the top right. In-between the letters B and C, and also C and D, are aluminum Heatsinks.
What looks to be finned rectangles arranged in a vertical strip.

When the fan's blades, center hub, and surrounding cage, (Shroud) are clogged with 'gunk', the cooling capacity of the Fan drops tremendously.

Same thing with the fins of the Heatsinks.

[Construction of an average Heatsink is a plate of metal with tall, thin fins protruding from it.
The plate of metal absorbs heat from whatever object it is placed against, and the tall, thin fins absorb heat from the plate of metal.

The fins then radiate the heat away. With a fan used in conjunction with a Heatsink, the fan pushes air in-between the fins, and around the fins. The air flow helps carry heat away]

Heat = Wasted Energy
The overheated Power Supply strains to keep up with the call for power, but eventually fails.
(Hardware components inside the Power Supply fail)

I'm willing to bet it's Power Supply failure.
Test the three main voltages from the Power Supply. (3.3 Volts, {Orange}, 5 Volts {Red}, and 12 Volts, {Yellow)

The next thing to be an inherent problem with an eMachine desktop computer, are the Electrolytic Capacitors on the motherboard.
Low quality capacitors are used.
(Radial Aluminum Electrolytic Capacitor)

Visual identification of bad capacitors, (Electrolytic),

http://www.capacitorlab.com/visible-failures/index.htm

[NOTE*
Not all bad Electrolytic Capacitors show visual signs of failure. Sometimes the Electrolytic Paste inside the capacitor dries up. No bulging case, or leakage will be present ]

Summary:
1) Computer unplugged from power, Anti-Static Precautions observed, clean the inside of the computer out.
2) Replace the Power Supply.

Also remove the Ram Memory modules, ('Stick'), and clean the gold plated contact pins on the ram memory module, with a pencil eraser.

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

(You can click on the photo to enlarge)

Your eMachines W3110 uses DDR Sdram ram memory.
184 contact pins. 92 on Each side.

[It is DDR Sdram that operates at either 333MegaHertz {333MHz}, or 400MegaHertz. {400MHz}. Also know as PC2700 or PC3200, respectively]

Handle the ram memory by the body. Refrain from touching the contact pins.
The body of the ram memory is coated with a see-through protective plastic, which shields it from Static.

The pencil eraser is rubbed going Down the contact pin. Start at the top, and go down. If you are using the eraser on the end of a pencil, and not a solid eraser, refrain from letting the metal band touch the contact pins.

After you have cleaned each contact pin it may look as though you have not done very much.
I assure you have. Doesn't take much 'corrosion' on a gold plated surface.

Use air to remove the eraser dust before reinstalling the ram memory.
You can use a can of compressed air for computers, or air pressure from your mouth will be sufficient.

Use compressed air to clean out the ram memory slot/s on the motherboard also.

Emachines e3415 problem


I would guess that the CPU overheated if the fans are noisy. I would remove the CPU heatsink clean and reinstall the CPU with the proper contact paste,reinstall the Heatsink along with a new heat sink fan, if that is the one is making noise also.  Then see if it will then boot up. If not I am guessing that the CPU was damaged for the fans not workingwell enough.
