You didn't mention if this is a laptop or desktop system and it may make a difference. Most cooling fans are temperature controlled and may run at different speeds during operation but laptops in particular will have a running CPU fan at power on; this is the hottest IC in the unit.

My new elite ceramic glass cooktop blows cold air from oven vents when using top burners. is this normal?


Normally I would expect the user manual to cover this unusual behavior, but sometimes they don't. Most new ranges have a considerable amount of electronics controlling things like temperature etc. These controls used to be mechanical, and not so sensitive to heat. This likely is normal operation, and that the fan is blowing cold air in order keep the electronics cool, and to extend the life of the components -just like a computer.

Cpu fan constantly running fast


An eMachines desktop or laptop computer fail to boot for a variety of reasons, but a fast, loud fan noise signifies that the system is suffering from overheating.


The problem, and the steps for troubleshooting it, is not unique to the eMachines brand. When the internal temperature of the computer reaches too high a level, the system will shut down automatically to allow the heat to dissipate.


If you attempt to power up too soon, the machine will not boot properly.

To boot, you will need to correct the cause of the overheating, and keep the machine cool.


Blocked Vents


Although different in size, both desktop and laptop computers have air vents to help the fans keep air circulating around the hot internal components.


If these vents become blocked, by pushing a desktop too near a wall or using the laptop on a soft surface, the air supply your internal fans need to cool the system is cut off.


This blockage also traps the heat inside, allowing it to build to dangerous levels.

Keep the air vents on your computer free and clear to allow proper airflow.


Dirty Computer


Airborne particles, such as dust, lint and hair, can gather on the air vents and internal components over the course of time.


This accumulation of dirt not only provides a sort of "insulation" to the electronic components, preventing the heat they generate from dissipating normally, but it also clogs the fan and heat sink to prevent proper function.


Use canned air and damp, soft cloths to thoroughly remove any built-up debris from inside your computer.

Dried Thermal Paste


The heat sink sits atop the CPU chip to help dissipate the heat the component produces. Thermal paste is layered between the CPU and the heat sink to help draw the heat away from the chip for cooling.


Over time, the cooling properties of this paste decreases, and the substance becomes dry and flaky.

You can replace this paste to renew its cooling assistance by removing the old paste remnants with rubbing alcohol and adding a new layer.


Thermal paste is also known as thermal compound or thermal grease, and is available at most electronics stores.


Hot Environment


When examining overheating causes, don't overlook the environment you use your computer in.

External heat sources, such as fireplaces or even rays of direct sunlight, can cause the internal temperatures of your computer to rise.


This causes your internal fan to run harder in an attempt to dissipate the combined heat before temperatures rise too high.

Move your computer away from external heat sources to encourage more effective cooling.


Hope this helps

What is the best temp to set your thermo for cooling a 2400 sq ft home?


I set mine at 73, seems to work for my home. Of course a lot of variables, Depends on how cool you like it, and of course how much you want to pay extra in gas/electric bill for this luxury. Of course I close any doors, or vents (if vented through vents) to not cool rooms not being used. On normal day that is in the 80's or 90's , 73 seems about right. Thanks Mike

My processor is getting hot. What will be the solution.


Turn it off ... it will not get hot.

Typically, normal temperature is over 100 degrees. There have been reports of fires starting as the result of a overheated PC. I am not making the claim, I have not had this experience.

Heat is the enemy of delicate computer parts. They call them Lap Tops but you should never use one on your lap. Always place your lap top on a hard surface to insure the vents are not blocked and the internal fan can try to do its job. If you are concerned about the heat, you can get a 'cool pad' to use under your lap top. A cool pad has a fan which blows onto your lap top to keep it cool. The cool pad gets its power from a USB in your laptop. This cool pad should not be used for long periods of time on battery power for obvious reasons.

The dryer won't dry the clothes. cooling light comes on. cleaned the vent looked at the gas connection etc..


You have a problem with the exhaust vent in the wall. Best way to test is to disconnect the vent from the wall and run the unit with a normal load. If it dries normally, you will need to have the exhaust vent cleaned professionally.
Good luck

When the cool air ceases, does any air blow? If your air flow ceases (the cooling fans run the entire time the A/C runs normally), your cooling fans might also be malfunctioning. How many times has your car overheated since the September 2008 head gasket replacement? Repeated overheating will dramaticly shorten the lifespan of a head gasket (if you and/or your husband know your way around cars, the head gasket replacement isn't terribly difficult, just takes ALOT of time- you can send an email to maintjoseph @yahoo.com -no space between the name and the @ sign- and I'll help guide you through the head gasket replacement). I had to replace both gaskets and a head on my 1999 Taurus with a Vulcan engine and have had continuing problems with the cooling system. Your computer might also be acting up if you're noticing other driveablility problems.
