Your PCU is overheating. Disconnect everything, especially power, take the cover off and give it a good cleaning. But be careful not to damage everything.

A vacuum and or a natural bristle paint brush are the best tools, but get all the dust and fluff out.

If it still does this, you've possibly cooked the heat sink paste which goes between the CPU and heatsink plate. Just under the CPU fan. But don't touch that until you've had a good clearout and tried it first.

My fan gets loud and then the computer shuts down. very irritating. How do I clean the fan? How do I get the casing off to get to the fan?


that varies. you'll have to tell me what kind computer it is. as to cleaning methods, use canned air, NOT air from a air compressor. The difference is that the air from air compressors tends to havemoisture in it. Don't forget to rate

you need to buy a new fan, your fan is about to give up the ghost. if you let the fan die while the pc is running, it might burn out the cpu.

fans are very cheap, like a few dollars, and do not always last forever.

If you say that fans gives out loud swirling sound, i can suggest you update your bios because it is the one responsible for minimizing the noiseand making the fans swirl.
Possible that system is shutting down because fans might be shutting down as well.
You can also try to blow out some air on the vents because that is usually where your fans are, this will help clean out fans.
Questions: Does your computer restarts when it shutsdown automatically? if it is there might be a bluescreen error going on and bluescreen can either be a problem with software or hardware. A lot of troubleshooting needs to be done to isolate. Do the first solution that i have given you then answer my questions for further troubleshooting

Computer frequently shuts down unexpectedly/ fans very noisy


You might have a cooling problem due to a fan malfunction. It is not clear whether it's the power supply fan or the CPU fan; in the latter case you might also have a thermal coupling problem. The symptoms you describe certainly seem to point to such.

My advice would be to replace the fan (or the whole power supply; you might also want to purchase a "Silent Power" unit for quieter computing). If it's the CPU fan and you are comfortable with, or know anyone comfortable with a bit of PC servicing, you might want to also unmount the heat sink from the CPU and replace the thermal paste between CPU and heatsink. Clean the heat dissipator (the black metal grille over the heatsink) with hot water and a bit of soap and dry thoroughly, or wipe it energically with a dust brush, before mounting the new fan on it.

Over heat cooling fan load noise remove and replace


A bearing more than likely has went bad causing your fan to stop properly cooling your unit. Replace with a compatible fan and you should be all set. Hope this helps.

I've had a bad dust problem and my cpu fan began making a loud whirring noise and finally the computer shut down altogether. Took the cover off totally cleaned out the dust and turned the power back on....


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.

My cpu fan will not shut off it is so loud should i replace the fan or is there a way to repair this problem


Your CPU fan should always be on while the computer is on. If it's off, your computer is going to crach in a matter of time. The noise is normal. If it's to loud, replace the fan. Nothing major. But it is normal for the fan to be loud. Thats a good sign it's cooling the CPU. But you can get a shfter 1. Your computer might over heat though. Good luck.
