Cleaning macbook pro fans

Lol, this is one of the funniest (read: silliest) arguments I've read on this forum so far. I wish I'd never asked!

Seriously, some people will argue over anything!

Nonsense, you obviously need to read more:p
 
Static is a major killer of electronic equipment and hoovers create lots of it. I was designing, repairing and building computers at the component level 20 years ago and like Neil have a hell of a lot of experience in that area. I have seen computers killed by hoovers before! Seriously Neil is giving good advice. An air blower or similar is far safer although I would be happy to hoover out a case once all the stuff is removed.

Yes clamping cases to earth etc is a good idea and all manner of anti-static precautions can help but it your computer is grounded and you bring a statically charged item towards it then the static will earth through the item causing problems.

The comments about doing A or B lots of times and nothing going wrong are plainly silly! If there is a 1 in a hundred chance of something going wrong you could do it every week for ten years without problem or it could happen the first time.

OK fun is fun, your silly comment compels me to reply.


How in the name o' the wee man, can you quantify 1 in 100 with every week for ten years.....

............. are you needing an abacus or something?



Originally, what really got up my thrupennies was this comment........

"...however those saying "ive done it loads of times and its fine" it can also, although not killing instantly, reduce component life..."

A statement that said to me....

........ don't argue with me sonny, I am an IT professional and know much more than you.



How on earth can you come up with the age of a motherboard, RAM, CPU etc. etc. when it depends largely on the use to which the component has been put?



Show me a verifiable link to the lifetime of computer components, then to the reduction in that life by static.

If such links are shown, I will acknowledge that my experience has misled me and apologise for my "smug" comments to Neil.



Of course I realise that static is dangerous to PC components.

My arguments are they don't just blow up with hoovering.



The very name hoover almost caused apoplexy from one poster here because it was so far beyond his ken.

They make hoovers for computers these day for goodness sake!

Oh well, I have only 12 years of repairing, building (don't know about the design bit though) computers at the component level , I obviously no nothing!

Nope....

It is right, 1 in a 100 in the first week...... then it is still 1 in a 100 in the second week...... then 1 in a 100 in the third week......

The point is that it COULD fail in week 1 or you might be lucky and it might fail in week 520 !

Just because it is 1 in a 100 doesn't mean that it will happen after 100 times or even within a 100 times.

It is basically the MTBF malarkey..... Some fail straight away and some end up as antiques :D

Well if it doesn't happen 1 in a 100 times, why specify it?

If some end up as antiques, your criteria (nobody else mentioned it) was absolutely and totally wrong!


Anyway, I look forward to your verifiable links, I certainly couldn't find any, but then again, I wasn't trying to stifle an argument!

Firstly I didn't actually say that it happens one in a hundred times. That figure was plucked out of the air as an example or IF it happens one in a hundred times then. The actual figure might be one in 500 but it happens....... (please re-read my post where I say *IF*, I was trying to point out that just because something might happen once in a certain number of times it might not happen to you........)

Secondly if something happens one in a hundred times then it doesnt mean that if you do the action a hundred times it will happen once! It is just that on average it would happen once in a hundred. This is basic statistics eg dice they have a one in six chance of being rolled and ending up as five. It is quite possible to roll a dice twenty times and not get a five (i.e. 1 in 731231688012595 or 5 / (6 to the power 20) ) or to roll it three times and get a five each time (i.e 1 in 36 ((1/6)X(1/6)X(1/6)) = 1/36).

Also the likelihood of damage depends on the type of component. Certain types are more easily damaged by static than others.

If people want to stick their Dysons in their computers then fine let them get on with it. Most of the time they will be fine but there is still a risk due to static and I have repaired machines due to Hoover/static accidents in the past.


And Mike

I didn't say anything about static reducing the life of components. I would be interested in seeing a link to that myself.
 
Neil and Darren are correct,
Darren was just quoting MTBF statistics, like you have 1:100 chance of being hit by lightning, that doesn't mean that you will get hit today, it just says that its possible.

When I used to do liquid cooling, all the components intended for cooling were tested on air first for about a week, to make sure everything was working properly before applying the liquid cooling parts, any component that went faulty during the testing stage could then be RMA'd without voiding warrenties.

I did have a few components that were either DOA or failed within the first week
you don't have to see a spark to know that static has fried a part, semiconductors don't take much to kill them, just a few milliamps can render a memory module dead.

Blah blah blah "I'm a computer professional" blah blah blah. This is still going on?

Was that meant to be referring to me?

Well my 3 year and 3 month old 17" MBP has been getting VERY warm recently. The temperature of the GPU was 83 degrees C and the CPU was 74 degrees C. To be honest the entire thing felt like it was on fire when I was using it. I seem to repair everyone else's machines but mine tend to take a back seat but "no longer" I thought. So just ripped it all apart and sprayed it all out with the old air duster and lo and behold the GPU is now at 59 degrees C and the CPU is at 55 I had to check with iStat just to tell if the fans were spinning and the hole thing is nice and cool :) Why do we leave these pesky little jobs too long!

I thought it was just trying to get the last word in before it gets replaced by a stonking new 17" MBP (and a lovely little 11" MBA)
