How dust can increase CPU temperature in a big way (amazing)

[MadKad]

I recently did a job for some one and within part of this job was having to clean out the inside of the system, I normally do this anyway and so should you every now and then, if you read all this you will see why as I ran a test to show people just how much dust can be a breading ground inside your computer case and this slows down your pc in a very big way because of the massive increase in temperature.

First of all I will start by saying that this computer is owned by some one that smokes next to there pc case, this in turn will also increase the amount of dust that builds up over time inside the computer, this is because the smoke from the cigarette goes inside the computer system and then makes a nice layer of sticky nicotine inside the case, then the dust sticks to this nicotine. Please note not smoking next to a computer doesn’t mean there will be no build up of dust.

Ok here is some picture of the inside of the computer case
















Now here is the CPU heat sink and fan, before I started cleaning the computer I got it running up to full temperature with no programs running, this temperature was:

CPU = 48c
And the fan speed on the heat sink was
Fan speed = 2857rpm

Now here are the images of the CPU heat sink and fan







now this is bad


After a really bad and dirty cleaning job of 3 hours, yes 3 hours I them placed everything back inside the computer system, here are some images of the system now clean.
















Yes believe me or not it is the same system.

Now after running the system and getting it up to full working temperature and with know other programs running, I checked the temperature and CPU heat sink fan speed, this you will think I am lying (I AM NOT)

CPU TMP = 39c
Fan Speed = 3276rpm

This was amazing to see that all that dust made the temperature on the CPU run at a whopping extra 9c and the CPU heat sink fan run at a slower speed because it was getting restricted but after cleaning this increased the fan speed of an extra 419rpm.

This in tern will increase the speed of the computer and the response time on running programs, also this will increase the life span of the central processing unit (CPU) and the CPU heat sink fan.

How often do you clean your computer?

[Whatcha]

Dirty rotten scoundrels springs to mine....how does that mean my pc is ready now then lol

[MadKad]

lol if yours is like this then get it cleaned please I feel sorry for all computers that have to live like this

[jarhead]

kad i thought u built computers not cleaned them

[Gamer Noob]

I never new that dust could build up like that and make so much heat, wow thank you for telling us

[MadKad]

kad i thought u built computers not cleaned them

we build them and cleening out the inside is part of a service we do when tuning them and restoring etc etc

I never new that dust could build up like that and make so much heat, wow thank you for telling us

np mate glad things help here

I know this is an old post, but this is actually amazing haha

I clean mine out about 3 times a year. That computer was well dirty.
