Ciaran Griffin/Stockbyte/Getty Images Just turning on a computer is enough to get the fan to run continuously.

Computer fans constantly run during normal use to cool computer components and prevent overheating. Many computers produce operational temperatures in the hardware-damaging range during normal use and require continuously running fans to not only prevent overheating, but perform optimally. Additionally, computer cooling fans help combat the room's ambient temperature, which, if high enough, can contribute to overheating the system. Fans Prevent Overheating As technology has improved, the materials that make up computer components have been pushed to operational capacity and can produce enough heat to break. The cooling fan circumvents the self-destructive heat build-up by expelling warm air from the system and allowing the components to operate at lower temperatures and reduce failure risk. For example, a computer processor may have a safe operational range of up to 60 degrees Celsius, but if left without any form of cooling, it will continue to produce enough heat to break into the 100 degree Celsius range.

This will cause the processor to burn itself out. cost of commercial duct cleaningOverheating Warning Signs Unless you're running temperature monitoring software on the computer, the computer fans running in what's often referred to as "jet engine mode" is the first sign that your computer is overheating. dryer vent cleaning vacuumComputer cooling fans do not run at full-blast at all times during normal use; sony laptop fan speed controlinstead, the fans spin just fast enough to keep the computer running in the safe temperature range. hardwood floor steam cleaner comparison

The computer may have a cooling issue if you notice a clear audible increase in fan noise. ways to clean your blindsIf the air is cool, but still coming out at full-blast, there may be a system configuration problem. best handheld vacuum cleaners for stairsCPU and Component Fans With the exception of cellular phones and tablets, modern computer CPUs are usually equipped with a heat sink and cooling fan combo unit that is necessary for the chip to operate. The cooling system lets the CPU run at faster speeds by removing as much heat from the CPU as possible; similar to how a radiator cools an automobile engine. The CPU could be clocked at a lower speed to reduce heat, but that would hurt performance. Other computer components, like the video card and motherboard chipset, may also feature cooling fans for the same reasons as the CPU.

Case Ventilation Fans Case ventilation fans are intended to expel hot air from a desktop system to lower the ambient temperature inside of the computer case. Any computer component can break if it's exposed to enough heat. The internal case temperature sets a baseline temperature for all components, which causes everything inside the case to run hotter as the temperature increases. Case fans work in tandem with component fans by expelling the hot air produced by the components and bringing in new, cool air from outside of the case.

Also another point i have my vid card clocked in this laptop and its stable has hell, course software allows this overclock and restore back to normal when not in 3d intensive programs.

I THINK both Dell and HP (and likely others, possibly Sony) had problems with overheating nvidia video chips on the mobo, and the way they "fixed" the problem was to patch the code to make the fan(s) run continuously. But the 'burnt' smell could be a cooking mobo. It was traced to a defective nvidia video chip design. So if your laptop uses nvidia chipset, you may have this problem.

The overheating chip caused the mobo to fail (interestingly near warranty EOL) and by masking the video chip design problem with their code patch for the fan, these two manufacturers took the ultimate failure to well past warranty. It was a sucky way to treat customers. They later integrated new design chips into their manufacturing lines. It took them quite a while to address the problem. Ultimately, I think they started swapping-out mobos but only if the customer knew what was going on. You can probably find out more about it by searching on the net. Lesson: whether you're buying used/refurb/retail, check for recalls and other "known" problems with specific models. Won't catch 'em all, but may help avoid some problems. edit to add: link to more info Also note that some laptops have problems with the power connectors. This can also cause the 'burnt' smell. Ultimately, the mobo or connector becomes damaged due to overheating. Toshiba had a lot of problems with some of their power connector2mobo designs.
