    Hey guys,

    About a month ago my computer started to randomly shut down and restart itself.
    I thought the problem was software based, and i ran a few scans to see if there was anything wrong, and to see if there were any viruses.
    After finding out that my computer was clean of any viruses, * and about 3 and a half weeks of putting up with it*, I downloaded hardware sensors monitor, and did a CPU stability test.
    My CPU sat on 50 degrees IDLE, and as the stability test ran it peaked at 60 degrees.

    I figured that my CPU was overheating under stress, and the safety feature on my board would make the computer restart to cool down the processor.

    I decided to do something about it, so i opened up my computer.
    I took the fan off the heatsink to have a look, and what i saw was horrible, hehe.
    There were clumps of dust all through the heatsink, and the fan was covered in dust as well.

    I cleaned all the dust of the fan with a tissue, and then shook it.
    Then i picked out all the dust on the heatsink, and blew at it.

    I turned my computer back on, and opened up hardware sensors monitor and checked the results.

    My CPU idle had dropped 13 degrees, mainboard had dropped 2 degrees average, and under load it peaked at 46-47. Also, the CPU fan had so much dust on it, that it was getting weigheed down enough to drop more than 200 rpm.
    It went from 2760 to 2965 rpm.

    My computer has stopped restarting, and is actually working noticeably better.
    So if you're bored, or there is a problem with your system, check your CPU heatsink and fan, you processor life will be longer, and you'll get better performance

    cheers guys!

    It's true for all parts, including case fans, PSU, video card and all heatsinks (NB, etc.). I even modded my Koolance case so I can take out the radiator and blow that out when I feel the urge. Last time I cleaned, there was quite a bit of crap in the fins. And I don't have any pets at the moment.

    I got an old PC from someone that was on 24/7 - I opened it up and took my gas powered leaf blower to it! Clouds of dust!!!! LOL.

    The last time i cleaned my CPU/cooler is when i removed the heatspreader from it.
    That was last week.
    I have two mesh fan filters in my case. That helps a bit but reduces airflow.:ohwell:

    i have 4 four fans now:
    one front blowing in
    one back blowing out
    and two side right next to my GCard blowing in

    dust filters wont effect the cooling that much will they?

    dust filters knock back air aout 30%

    as long as you have moving air in the case, the amount doesnt matter so much.

    Oh and my compressor cost $120au, with hose/fittings. its really convenient :p

    I only just got my new Q6600 and MB last week and my fan seems to be fine but occasionally I blow the dust of the fan or use a cloth. I remove dust from the front of my Antec 900 cause I noticed dust builds up there.

    i find the 1" does the best job on fans because it can get into the blades better.

    for cpu heatsink i use a 1 1/2" with the bristles cut off about half way. this stiffens the brush for better cleaning between the fins.

    Well my dad bought an air compressor (he says he needs it...never saw him though lol) so I use that about once a month, and every few days just use a brush to get rid of the surface dust.

    I run an air cleaner in my computer room, and I use an air compressor to blow er' out once in a while. I have 4 intake fans and 2 exhaust fans not including the 2 exhaust fans on the psu.

    Then, wait half a week for your parts to dry out, then reassemble... :rolleyes:
    it's much simpler, easier, and faster to just take a can of compressed air (or an air compressor) to a few HSF's and fans once is awhile than it is to disassemble and reassemble the whole thing :)

    Exactly...

    If you have a bunch of systems or are really picky, simply buy a case of compressed air, its really cheap then... Cheap small air compressors are not that expensive either, just remember to give it a few second shot before you aim it at the system to get rid of any moisture in the lines, don't want that on your boards.

    If you want a vacuum there are many hand held battery powered and corded static free vacuums specifically for electronics that work great, I bought a small one it cost me like $20, of course the 1 1/2" fine paint brush *static free* works wonders also.

    Can a small air compressor work, like the 1 which is used to pump wheels for a car?
