compressed air and cpu fan/heatsink

quick question.

i've noticed the interior to my computer is getting dusty. is it ok if i use compressed air on the cpu fan and all that jazz. because it's really bothering me and i can tell a difference in the dB levels because the fan is having to strain against the dust build-up

 

Yes!

Just make sure you haven't shaken the can or anything like that, that would introduce liquid into the electronics.

 

I usually talk my brother into cleaning mine out but I do know he uses compressed air and we haven't had any problems with my computers so it must be ok

 

Also make sure the power is off & let it sit for a few minutes before powering back on, just in case there was some of the liquid sprayed on.

 

Yep!
I use a compressor, on dozens of PC's.
On the real dirty ones you'll usually see a reduction in temps too!

For my own PC's, I filter all incomming air, then I usually only have to clean the filters and exterior.

 

I wouldn't reccomend using a real air compressor unless it has a moisture trap on the line.

 

Excellant point, and I do.

I guess I also should point out if using compressor you should be careful not to use too much pressure, you wouldnt want to cause any damage.

 

Hi,

All good points, here's another, try and hold the can vertical and resist the temptation to turn the can on its side. This is usually when moister will come out. When you can't reach what you need to then slide the machine to the edge of a desk and this will allow you to lower the can.

If you use a compressor use one with out a tank then there is no moister and not alot of pressure but enough to blow some dust out

what if you took an air compressor, like one u use for pumping up your car tires, and put the pressurized tip on it.... it will def give enough pressure to blow away dirt... but how safe is this with the moisture deal.. there shouldnt be ne moisture from this correct??

my thinking here was that just a regular old air compressor is around 15 bucks and compressed air can is around a couple of bucks... well with so much cleaning.. wouldnt it just be better in all around to just get an air compressor??

save money in the long run and blow as much as you need ....

can someone help me out if this is no good before i go and buy it....

thx!

 

That would work, but you'd have to be extra careful not to get too much pressure. I would suggest tryin' that out on something before blowing pieces off the motheboard.

 

That what I was referring to earlier but I don't think you would get enough pressure but I know you won't get any moisture.
