Processor gets hot, fan speeds up, and processor throttles itself down to prevent frying itself.

Air vents blocked, processor heatsink clocked with dust?

Yes, insufficient CPU cooling is almost certainly at fault here. If dust does not turn out to be the culprit, check to make sure the heatsink is securely latched to the CPU. You may also want to apply some fresh thermal grease between the CPU and its heatsink...this is available at any computer supplies store.

Do you take the side cover off when you clean? If not you need to. Also remove the side cover and make sure the fan is working correctly.

A heatsink is a block of metal (usually aluminum, sometimes copper) that sits on top of your CPU. A fan is usually attached to the top of it, although at times is on the side of it. Like others have said, if your CPU is overheating, it may very well throttle itself down to a lower clock speed and thus cause performance issues. You can check the BIOS to see what the CPU temperature reads (most BIOSes support this). If it is higher than the threshold level set, the processor will throttle itself or the CPU may give an alarm or even shut itself off completely. You need to make sure the heatsink--that block of metal that looks like it has been cut with a pattern (usually a horizontal and vertical cuts) and has a fan on it--is firmly attached to the mounting mechanism that surrounds the CPU.

Since you might not be very familiar with all of this, I suggest you take it to someone to look at. Because it is possible you could damage your PC if you attempt to resolve the issue yourself.

1) Clean out dust in the system, especially that around the processor (which is hidden by heatsink and fan), as well as the case fans that should be mounted on the back and even front inside of the PC.
2) Monitor the temperature of the CPU in the computer's BIOS and see if it appears to be overheating (your CPU should not be over 60 degrees Celsius idling and usually a good average temperature is in the 30s Celsius up to low 40s when idling).
2b) Also make sure the fan is set to auto if your BIOS allows it; it should not merely come on when the processor exceeds a very hot temperature, but instead be pretty much always running; you might think it is not running because the fan is at a low RPM and thus fairly quiet; don't confuse the jet-engine sound with it just coming on, as it is merely increasing the RPM to probably near maximum.
3) Make sure the heatsink is firmly mounted on top of the CPU.
4) Take the heatsink off and make sure there is a thermal paste compound spread evenly over the die of the processor in the center. (NOTE: if you attempt this yourself and don't know what you are doing, you could damage the CPU, motherboard or heatsink mounting mechanism). This thermal compound helps spread the heat over a wider surface area and helps with cooling.
5) If the fan appears to be problematic, you could try replacing it (I'd recommend buying a heatsink/fan bundle that is compatible with the CPU socket; if you actually get to this step, we can help you identify the type of CPU socket you have).

- Unplug and let set overnight.
- Get a grounding bracelet to work inside as static zap will damage your board
- put on latex gloves, grounding bracelet and clean out with an air can and a camera lens blower.Finger grease will damage your board and make dirt stick more

Gunk also gets up in the actual fan so thats where you will use the photo brush

Bigger programs like gaming and photo stuff make your processer create a lot of heat. You can get extra fans to put in your computer. Some of them light up. They are cheap too.

heat and dirt = slowwwwwwwwwwwwwwwwwwwww



Good luck!

WHOA! Way too much scare tactics and incorrect information here.

The system does not need to be unplugged overnight. A minute or so is fine.

Static is a problem, and precautions need to be used if you are removing expansion cards, adding memory, etc. There is no need to touch any of these components to blow the dust out.

Gloves are not needed, never heard of such, and I have worked on computers from mainframes to servers and everything in between for 30+ years.

A photo air bulb probably doesn't have enough umph to budge a build up of serious dust, canned is the best bet.
* Do NOT overspin fans by blowing a strong blast on them. If a fan needs cleaning, hold the fan and blow the dust off the blades.
* Do NOT use a long blast of air on a component as it can cause it to become very cold to the point frost (condensation) can form on it.
* Do this in a well ventilated area, a dirty PC will create a huge cloud of dust in the room.

A vacuum on blow can be used, but with a lot of caution. Again do not blow on fans as it will overspin them. Do not let the hose or attachment touch anything as most hoses are plastic and build up a large static charge on them.

Do not attempt to remove the heatsink, processor damage is a possibility and you need thermal compound/tape to reinstall it properly.
