Fan noise I find that the side mounted fan is noisy in my new PC with 8870LK case.

PC fans fail all the time, nice thing is they are fairly easy to replace. They fall into several categories but mostly are easily identifiable. First you need to know the size of the fan, they are usually always square even though the bore of the fan is round. The most common size is 80mm, but 40mm and 120mm are also common. This is measured by width and height always being equal in most cases. You will need to open the case of you computer and determine the electrical connection of the fan. Some case fans are connected to the main board of the computer and some are connected directly to the power supply. All PC fans are powered by 12 Volts DC power. You will usually have at least one black and one red wire going to the fan. The red is positive the black is ground. It is fairly common to have fans with three or even four wire connections. The additional wires accommodate tachometers and temp sensors. Fan noise is caused by two factors, noisy bearings or blocked air flow. One of the more common fan noise problems with PC's is the CPU fan and heatsink is clogged with dust and dirt. The noise you may be hearing may not be fan noise but a actual on board temperature alarm of you CPU over heating. Visual inspection of your CPU fan and heat sink will show this problem. If it is dirty by a can of canned pressured air meant for PC cleaning and carefully blow out the dust and dirt accumulated in the CPU heatsink. Do this with the PC off and unplugged. Canned air has a tendency to condensate and get cold, be cautious not to drip moisture into the PC or mainboard. If the CPU fan is not the issue then the noisy fan should be easy to identify with the side door off and the PC plugged in and turned on. Once you have found the fan in question identify the size and electrical connection type. Replacement fans are easy to come by as well as electrical wire harness converters to get you what you need to replace the fan. Amazon and Newegg are both great resources for finding replacement parts. If you really want to get scientific about it examine the bad fan and google the model number on it. Look at the specs and see what the RPM, CFM numbers are like on it to help you find a suitable replacement. In some computer cases you may have the ability to replace the fan with a bigger slower rotating fan, this is beneficial for a less noisy computer. Also when installing the new fan pay attention to the airflow direction of the fan. Some people like more airflow going into a computer case therefore pressurizing it against dust in flow. Does the computer sit on the floor? Is the floor carpeted, do you clean your computer out on a regular basis? Do you have pets? All these things can contribute to a dirty computer that can run to hot and shorten the life span of the parts inside. Hope this helps.

Could be the case fan or the CPU fan. Open the case and determine which fan is noisy by unplugging them one at a time. Replace the bad fan with a new one and you are good.

That's because it heats up more easily and faster, which usually makes the fans spin faster and results in being noisy. Have you ever cleaned out the interior of the computer? If not, or if it's been awhile since it's been done, then buy some canned air for dusting electronics, open the side of the computer case (while it's not powered ON), and blow out the fans and the heat sink. If you get alot of just clogging up the heat sink, then it will not dissipate heat correctly; which results in the fans running more often. It that doesn't help any, then I would try to figure out if one of the fans is making alot of noise because it's going bad. You can find replacement fans on ebay, or at local electronics\computer shops.

HI. Just so you know, Hissing and popping is normal on frost free refrigerators, it is the defrost heater, in this case. I would check these following areas to address any other abnormal noises.

If the level of the unit is not adjusted to proper specs, this will create an unstable operating condition, causing many noises to emit from the units structure. inspect the unit for proper level. adjust if needed. Next will be the drain pan. Once removed for cleaning, the pan must be replaced in position correctly. If not, the pan will rattle against the compressor, causing a ping or rattle.Simply reposition the tray if this is the case. The third possible issue will be the condenser fan. The condenser fan is located behind the refrigerator. It may be necessary to remove an access panel to reach it. This fan has a shroud, and if the fan blade becomes warped, it will rub against the shroud, causing noise. This fan blade is whole,and it can be removed and replaced if this is the case. Ok, the fourth problem spot will be the evaporator fan.

The evaporator fan is located at the back of the freezer. It may be necessary to remove obstructions such as the contents of the freezer, freezer shelves, ice maker and the rear inside panel of the freezer. The rear panel may be held in place by retainer clips or screws. Remove the screws or depress the retainer clips with a small screwdriver. Check the fan for warped blades. if the blades are warped or mis-aligned, replace it. This fan also is protected by a shroud as well, and it will make noise if the fan blade is damaged.

Last, i would move on to the compressor mounts. This is the most common spot for noise overtime. The compressor sits on rubber mountings. Those rubber mountings are designed to absorb vibration from the compressor. As the mountings age, they can become hard or disintegrate. When this happens, the compressor vibration is transmitted to the refrigerator structure and it can cause noise.


The compressor is located in the rear. It may be necessary to remove an access panel to get to the compressor.

Locate the compressor and remove the screw or retaining clip of just one of the compressor mounts.Using a pry bar, lift up the compressor enough to slip out the rubber mount. Inspect the mount for deterioration. The rubber should be firm but not rigid. If the mount is crumbling or hard, it should be replaced.


This concludes the inspection procedure. Follow carefully, and replace any failed or damaged device.

That's usually mounts inside the compressor. It could still last awhile so if you can put up with the noise just wait for it to quit before replacing the compressor or getting a new fridge. If it doesn't seem to be coming from the compressor you have two fans, one in the freezer and one near the compressor which could be noisy from hitting ice or wearing out.

HI. The most common issue here will be with a loose motor shaft. This is the part that the fan blades are mounted on. When this occurs, the looseness will cause the motor, and shaft to wobble, thus, causing this noise you here at high speeds. The wobble is less violent during the slower speeds, so it is not loud, in this case.

The second issue will be a warped fan blade. This will cause the fan to rub against the shroud, thus, creating the noise, as well.

If the shaft is loose, or bent, the entire motor will need to be replaced. Now, if the fan blade is warped, you can, simply, unscrew the blade from the shaft, and replace it(on most model)

Acer Aspire E500A fan noise

nope..and you'll need a new fan..what's LP? did you mean HP?

Returned to home depot. Fan was broken.
