The inside part of the fan should be able to be taken out for cleaning. The best thing to use to clean the blades is compressed air, or if thats not an option then an old toothbrush should do the trick.

How to Clean a PC Fan?

If this is inside a desktop unit, you need a good vacuum cleaner hose and a small paint brush. You can use the hose to get the big stuff off the fan inlets, then you use the brush to get the blades while using the hose to catch the dust. You can also take the cover off the case and use the vacuum in there in combination with the brush. If this a laptop, your best bet without taking it apart is to use canned air.

Does the Optoma HD20 DLP projector have a air filter? If it does, where is it located?


The Optoma HD20P doesn't have an air filter.
If you remove the covers you will find 2 cooling fans that get a build up of dust on the leading edges of the fan blades.
These can easily be cleaned with a small paint brush and a drinking straw to blow out the excess dust.
If you are having overheating problems, please view my post on replacing the heat sink compound on the image processor.

Hi I would like to know what kind of spray or solvent to clean the dust inside the TV section, I am in the process of changing the Lamp on a samsung TV .I highly appreciate the help

one way to clean a lcd projector or DLP set when have taken the lamp door off and pull the lamp out use a small brush such as around the house small paint brush or tooth brush and with light see the fan or fans and loosen the dust on fan blades and while doing this if have a small vac or shop vac where the end is small enough to fit inside to vaccum out the dust. If feel safe to take the screws out the back of set and just lightly vaccum out set. Some guys use a can of compressed air that you can get at Radio Shack or possible Lowe's. This is ok just be careful and use vaccum at same time so dust will not go up into the optics/light engine assy in which the lamp is attached to. Really do not need to spray any liquid inside set and always pull power cord before you put hands inside set.

Casing getting hot, fan going mad then slowing down

Have you ever removed the side panel and cleaned out the dust from inside the computer case?

If your fans or air inlets get clogged up with dust then your machine will run very hot and could eventually shut down or cause permanent damage.

Unplug all the cables from the back of your pc, and remove the 2 screws from the back panel that secure the side panel. Then just pull back on the side panel and it will pop off.

Clean out all the dust from inside the case. You can use a vacuum hose but don't bang into anything with it. Also use a small clean paint brush to lightly brush the dust off of the fan blades and the CPU heatsink and around the power supply air vents. You can also use a can of compressed air if you have it to dislodge the dust and then **** it up with the vacuum.

Good luck and please comment back and RATE if this was helpful.

My laptop cuts off as if the whole house had a power failure, this is getting more frequent. it seems to have to cool down before it can be restarted. Any suggestions?

is your cooling fan, or fans, working? or your laptop placed where the fans can't circulate the exhaust air out properly? seems, as you've observed, there's an over-heating problem. you in a dusty environment?have cats!?? i have- and could probably, between dryer, fans, etc. build 2 or 3 kittens out of their sheddings!
if you have your fans on the back, or bottom- then make sure they're not obstructed by cloth, paneling, or 'dust bunnies'! use a vacuum on low, or partially cover end of hose, and **** the dust out of fans, if present! turn on laptop, and see if fan, or fans are spinning! don't use a compressed air can to clean them!!! can crud-up mechanicals inside laptop! perhaps use a very fine artists brush to loosen debris from fan blades, before you 'gently' vacuum out dust!!
good luck!

Excessive lint/dust on coils in overhead compressor compartment

only you can see your coils[condenser]if you have cleaned them well,that could be fine.their's nothing mysterious about it.also the condenser fan blade should be a repairman i would use a small shop vacuum and a condenser coil brush only.i would wipe dust off fan blade with my hand as vacuuming.only if in a greasy environment would i use cleaners.i serviced in an hot climate and if that was the problem my efforts always solved the problem.if your temps have become normal you may have done fine.but you can reevaluate with my council. God bless ,tom

System shutdown

Systems that shut down after being powered on can point to an over heating of the CPU. Other factors come into play with overheating. Too much dust build-up on & under the CPU fan blades. Dust builds up in-between the heatsink fins (Thus the CPU fan can not cool the CPU chip.)
The CPU fan may be running too slow. When the PC system shuts down it’s saving you from hurting the system. You did not list the model number of you're system. Check you're system & clean the mentioned parts. Use canned air & a dry clean small paint brush to help remove possible dust buildup blow the dust away with the canned air.

Trouble shooting of motherboard

Hi thayal, systems shut down because of over heating. This is normal so nothing burns up. Try opening the case & clean the CPU fan. Remove any & all dust from the fan blades. Use a clean non used paint brush to help loosen any dust build up. Than blow the entire system out with canned air. Blow out the power supply as well. When finished put the case back together & see if the system shuts down.
