The best solution is that you have to buy another new Fan for your pc before it move out of hand.
The fan is faulty and the little checking you have done is some how recommended for the fan to have work better but since then you have to change it for a better one before it have anything to do with your processor Malfunction.
bye.

Acre z5700 turns off


A really loud fan can be one of two things - neither is very good to have for very long. Most newer motherboards support multi-speed fan operation based on CPU temperature. This keeps fan noise at a minimum because the fan only has to run fast (and loud) if the CPU exceeds a specific threshold temperature. The loud noise could also be from a fan that is starting to fail and is binding, thus running slower than normal. Either of these conditions is indicative of a problem that kills PCs - heat. Open the case and carefully examine the heat sink fins and the fan on the CPU. If they are caked with dust (especially the fins), then the CPU will likely overheat and shut down. Get some canned air designed for cleaning electronic components and blow the dust from the fins and the fan. Restart your system a see if the fan runs slower and quieter now, Machines that are in dusty environments, around smokers, or placed on the floor are especially prone to dirt buildup. Periodic cleaning with the canned air is the way to keep your PC happy and healthy.

I have a DC7100 P4 CPU and its working but the fan seems to be running faster than normal, I already cleaned the inside just to be sure that there is no dust but still its creating loud noise from the fan....


Simple checkup to confirm that: install this free program
http://www.cpuid.com/softwares/hwmonitor.html
and it will tell you the real speed of your fan and the temperature of the processor. If the fan is really fast then most likely cause it the fact that the thermal paste between the processor and the radiator has dried up. Take out the radiator, clean the old paste, and put new one - you can find it in every pc shop.

Iam using HP Desktop D530 when i open some programmes but processor fan runs so fast and loud 2 gb ram in my pc and hard disk is 20 gb how can i reduce noice of fan ?


To reduce the fan noise, open the PC Case and clean the fan. Also, proper ventilation keeps the system cool and the fan runs at lower speed.

Hope this helps!

Some fans are automatically temperature-controlled -- they speed up, and, of course, make more noise, as the temperature rises.

Background tasks, such as Windows Automatic Update and scheduled virus-scans, can cause the computer to become "busy" when otherwise "sitting unused".

Next time the noise increases, enter CTRL-ALT-DELETE and open "Task Manager", and click the "Performance" tab, to see if the CPU-usage is reaching 100%. Click the "Processes" tab, and then click on the 'CPU' column-heading, and click it a SECOND time, so that Windows lists the "top" consumers of CPU at the top of the list of processes. Which process is consuming the majority of the CPU?

Dell Demension runs great but loud fan noise that takes a long time to shut down. What going wrong?


I had a similar problem with excessive fan noise on my Dell Dimension 5150. The solution was to replace the worn heat sync compound that was between the cpu and the heat sync itself. (£0.99 ebay)

If the computer detects overheating or fan failure it will shut down automatically. If you replace the fan you should be fine. Remove your old fan and try to get one that connects the same way, some of them connect directly to the heat sink, others to the motherboard.

Cpu fan noise problem


You should check and make sure the inside of your computer isn't dusty. Dust will wreak havok on fans and shorten their life. Plus it likes to build up between the fan and heatsink which will overheat your processor. Take the fan off and spin it with your fingers. I like to open the little sticker on the bottom and put some 3 in 1 oil to lubricate it. A smooth spinning fan is a happy computer. It also reduces noise that a dirty fan makes. Hope this helps you.
