Macbook Air Overheating

Hey guys,

My Macbook Air kept overheating. The fan was running nonstop. I tried watercooling it, and now it wont start. I think I may have been too slow/let it run overheated for too long and maybe?

Is there anything I can do to get it to start or am I out of luck? I knew I should have let sit in the sunny room without trying to cool it first.

Imagine that.........LOL

The MBA will shut down on it's own before it over heats to the point of damage.

If a Mac, or any modern consumer or workstation computer, is nearing overheating, it will shut down.

As you tried to cool it with water, in what way is unknown, you probably have damaged it with water, thus making it no longer functional.

It was in clamshell mode though with a plastic case, so I don't think the water hurt it.

Chances are that it did get wet, since it won't boot. If it truly did overheat and shut down, it would boot up after it cooled down.

Can you describe, how exactly you tried to watercool it? Since that information is lacking, further help is kinda far away.

Your MacBook Air was not overheating. If it was, it would have shut down.

Your fans are always running when your Mac is on. They spin faster as needed to keep temps in a safe operating range.

That's because using water on a Mac is an incredibly foolish thing to do and can result in permanent damage, not to mention voiding your warranty.

I think he meant "Waterboarding", not watercooling. Works wonders when data is not forthcoming...

Not always the case. My 2012 system is rated by Intel for a TJunction Core maximum temperature of 105C, and yet I can easily push it up to around 110C without a thermal shutdown. The system does however attempt to throttle back the processor to stabilise it at the maximum of 105C.

This machine does have a lot of issues however, unfortunately, and frankly has been a little disappointing for a near top configuration unit priced at $2499. It will likely be back in the repair shop again this week for more Logic Board work.

The fact is, it will shut down before any damage occurs, regardless of the specific temp. The processors can handle much more than 105C without damage. The shut down occurs before an unsafe temp is reached.

Intel 3720 qm overheating?
Quote:
The TCase for this processor is 105 degrees Celsius.
The TCase is a number established by Intel® as a point of reference in order to understand what could be expected as per normal processor temperature.

Anything from the Tcase and below will be the expected temperature of the processor in normal use, anything that doesn’t stress out the processor (watching movies, burning CDs, browsing the internet, creating documents, etc.) When the processor is stressed out meaning that you are running heavy processor applications that take control of the CPU or uses it at 100% the temperature will go beyond the Tcase. It can perfectly reach 115 to 120 degrees and the processor will still be OK. The cooling fan is in charge to keep that temperature there.

If the processor temperature reaches 130 degrees or more it will send a signal to the motherboard to shut down to prevent major damages and most likely it won’t be possible to turn the computer back in until it cools down.

The normal processor temperature will depend on the chassis type, the hardware involved and the location of the computer, and it usually is lower than the Tcase.

I just used a bottle, though it's not very advanced.

Again, lacking information. What did you do with the bottle?

Well I essentially put it in a tub with the cooling liquid in order to bring it to a better temperature. After that it wouldn't boot.

As mentioned earlier if pushed to the limit it shuts down.

When that happens to mine I just hose it off in the driveway. Because its off, the water never harms it.

However nothing is without its drawbacks. It takes a big tub of rice & two full weeks to dry out.

Dry the tub or get a new one. Unplug it leave unplugged.

With it UNPLUGGED, put 2-3 inches of rice in the tub, then the MBP in the tub with the rice, the cover the laptop with more rice.

Then let it chill for about a week, plug it in and see if it boots.

Also if it boots, the battery is most likely shot/shorted.

All this would Not be covered by Apple Care.

Please, no more water cooling

Come on, we have seen stranger things. And for a troll this would be a really low entry, thus it can only be true, without pix and all.

Maybe it was lube.

OP, we still dont understand what you did to "watercool" your Mac.
What did you do? Stick it in a tub of water? While on? What's the point?
My Macbook Pro's fan runs at 100% while watching netflix in bed, with the CPU hovering around 80C, but I know it's fine, as it is not past the thermal threshold. This post is either a troll or a spontaneous act of stupidity.
