Cool G5 tower owners - warning - don't get clogged up

We had one severe case last year.
Another case today and perhaps a couple more oddly on the same day.
Increasing fan wind up on G5 towers due to clogging cooling system.

Anyone who stands behind a g5 tower knows how much air they move through.
Now they've been out in the field for a couple of years dust and debris is accumulating and this is not covered under warranty.

If your G5 tower has been showing extra fan activity lately then I suggest you do a physical inspection to see how dirty it is inside and also use a thermal checker to monitor the various heat sensors.

Machines on the floor are particularly prone to debris build up. Also be careful of putting towers in enclosed areas or too close to the wall as that will impact cooling.
It's easy to forget as a G5 tower is so quiet that it is moving tons of air through it and dust and debris will build up.
Serious build up should be taken care of by a tech.

Good advice MacDoc. I have also recently fixed a couple of G5 towers with the same issues. Blocked airflow == meltdown!

I've also seen quite a few recently where the fans have gotten _extremely_ loud .. not more active really, but very loud due to bad bearings or axles or whatever it is at the center of them LOL. Hopefully this is not a sign of things to come with aging G5 towers!

Good advice. Already checked mine out a couple of months ago, more out of curiosity than anything else. Yup, the fans were surprisingly schmutzed. Took them out and gave them a thorough cleaning.

how do you suggest keeping it clean, not just a serious build up ?
give it a once over with the vacuum ?

Certainly not a vacuum - far too much risk of static.

For light clogging compressed air from a quality source designed for electronics is fine but don't get too close to a motherboard as it can freeze.

I can't give universal advice as some here are comfortable right down to disassembly while others are not. Point is to be aware and proactive.

First signs are fan activity increasing BUT I'd visually inspect any G5 tower on the floor that's been there for a year and any G5 tower period 18 months old or older or any G5 tower in a known dusty environment.

There will be some dust in any machine and I'm going to try for some "see through" back to front photos on the clogged one we have here versus a new unit.
Might be hard to get a shot of it tho.

Hey MacDoc. Great timing on your post. I just moved my Dual 2.7 off the floor because it was getting so dusty.

I've used the compressed air, but I'd like to more throughly clean behind the beautiful G5 | G5 on the inside of the machine. I believe this is where the chips and liquid cooling is housed. How do I take off that G5 | G5 cover so I can use some more compressed air.

Thanks.

Once more be careful - your liquid cooled unit is not as prone to overheating - have look online for disassembly and just shine a light from front to back and you should be able to assess if you need to go further.

For dust just shut the computer down, remove power and used compressed air to blow it out.

Just get take it outside and out your garden hose. Attach one of thos pressure washer things also. Oh, and make sure its plugged in and you have your monitor set up too.

Seriously though, is century duster or dust-off any good for this?

Just be aware that compressed air has sufficient force to damage the heads of optical and removable-cartridge drives, if directed into the mechanism. Don't hit the DVD with compressed air.
