Very loud fan!! Sounds like jet engine and make the computer shutoff.
I have had my pavilian ZV5000 for about 3 years and the fan runs constantly, never shuts off and most times is louder than the TV. The fan goes nuts even when the computer is just powered on and I am not doing anything with it. I called HP and they want $250 just to look at it. Anyone else run into this? Thanks

I wish I was a furnace expert but I will give a push in the right direction. When a gas/electric fan runs it has two speeds. When you turn on the FAN ON switch it should run at the slower speed. If it doesn't turn on or turn off again when you turn it back you have a wiring problem or a thermostat problem. Make sure the thermostat is compatible with your unit and wired properly (on both ends). The other time the fan runs is "in session" when heat or cooling is applied to the system. It should run until the system finishes the cycle then a bit more (30 seconds or 1 minute) to blow the treated air completely through the ducts. If it doesn't stop then you may have a bad fan time delay or relay. Check parts for your model and various appliance repair site online.
If this is a recent change in PC behavior, then it may be over-heating.
When was the last time you blew the dust out of the case ? This must be done 1 or 2 times a year, (more if you live in a dusty environment -- desert.)
Get a can of compressed-air, disconnect all cords, take the side off, take the tower outside, (you do NOT want to do this indoors -- trust me,) and blow it out. If there is a 'shield' on the heatsink, remove it so you can blow out between the fins there. Don't forget to blow out the Power Supply.
Tip : When the can gets cold, then the air will begin to freeze at the nozzle and it will become less effective....so STOP using it when it's cold -- you are just wasting the propellant. It is best to use TWO cans, one at a time....switching when one of them gets cold.
Its not a problem if you have the computer running all day long. Get an additional fan for your computer. An additional fan will reduce the noise as more fans running at low speed produce low sound that a single fan at high speeds. Make sure that the CPU is free from dust. More the DUST, higher the heat and higher the noise.
Self-defrosting refrigerators use a circulating fan to move the air through the freezer and refrigerator compartments. This fan runs whenever the unit is cooling. The fan is located in the freezer.
Over time, the fan may become noisy--usually making a chirping or squealing sound, though it may make a loud groaning noise instead.
To find out if the fan is causing the noise, just open the freezer door and push any fan/light switches. If the noise is louder when the door is open, the evaporator fan motor is the cause which can't be lubricated or repair instead required to be replaced.

Laptop fans DO NOT run constantly. They only turn on when booted up and once the laptop has reached a certain temperature. You should probably time how long for a shutdown, record your results. Let laptop cool for 10-15 between attempts. If it takes approximately same amount of time to shutdown between attempts it is very possible its overheating.
Other things like Viruses, software conflicts, and Harddrive problems can also be the culprit. take a look at the administrator event logs for any clue there. Event logs are in control panel under Administrator Tools.
I don't recommend trying to fix any overheating issue you may have, as that would entaiil disassembling your laptop. Unless you have a bit of experience in this, I would take it to a good repair shop.
Hope this helps you some. If so please rate my solution.
In side you're ZV5000 are two fans. These fans sit on a spindle which spins. The spindle may be worn which is giving you that loud noise. (Or a fan blade could be bent or warped from heat). The fan it’s self may be loose & can be tightened. The only way to check if the spindle is worn would be to dissemble the ZV5000. With the correct instruction you can check the fans. (And also clean the fans & copper heat sinks). Here is a link to do this you're self, including pictures. http://www.instructables.com/id/Cleaning-Your-Laptop-Cooling-System/ It's worth taking a look & saving you're self a few bucks.
take the cover off the fan in the freezer section and see if the fan blade is loose or hitting ice the blade just pushes on make sure the mountings are tight its probably the blade but you might need to replace the motor if i reamber correctly on the cover there is a screw at the bottom you remove then slide the cover up and its on hooks plastic hooks built on the cover ok
