Thank you everyone, who has participated so far.

Here's a test sequence that I just completed, with a stopwatch.

Start up cold... in an air-conditioned room... with the back uncovered and propped up to allow airflow underneath.

* Starting baseline temp = 49C
* Ran SetCPU stress test for 3 minutes. 80C
**Waited 1 minute to cool a little.
**Ran SetCPU stress test for 5 minutes. 84C
**Waited 30 seconds to cool a little.
**Ran SetCPU stress test for 4 minutes. 90C
**Waited 30 seconds to cool a little.
**Ran SetCPU stress test for 3 minutes. 88C
**Waited 30 seconds to cool a little.
**Ran SetCPU stress test for 3 minutes. Boom, reboot at almost exactly the 3 minute mark.

So that's 18 total minutes of Stress Testing with 4 brief random breaks in between. And finally a crash.

When I picked up the A700 after each stress test stop, the back was hot. I'd call it uncomfortably hot but not "burn my hand" hot.

Resetting my display timeout to 30 minutes, then am going to run one straight stress test. Let's see how long it takes to force a reboot.

Well that was interesting.


Starting temp - 56C

* @ 3 minutes & 40 seconds, the screen momentarily "wigged out"
* Picked up @ 6 minutes. Warm but not nearly as hot as before after reboot.
* Picked up @ 10 minutes. Same, warm but not hot like before.
* Picked up @ 17 minutes. Moderately hot... expect a reboot shortly.
* Picked up @ 22 minutes. It's hot. Switched to System Tuner to check temp (which stopped the stress test)... temps steady at 89C. Immediately went back to running stress test. Maybe 20 second gap.
* Screen wigged out again at 26 minutes. Picked it up & it is moderately hot
* Reached 30 minutes! Checked temp = 91C

Decided to call it quits. Temp down to 67C after 60 seconds.


What I find most interesting is when I switched over at 22 minutes... the A700 felt hot BUT the CPU still hadn't really exceeded 90C. That makes me speculate that the reboot & "hot feeling" is more due to ambient heat buildup over time, vs the CPU being pushed beyond 90C.

Oh yeah, and the left side of the tablet is just fine. Perfectly cool & I checked the temp now - 30C and holding. I'm fairly certain now that it's all about the "gap" on the right side above the mainboard and trying to get as much heat off the mainboard and onto that back plate as possible.


Damn... I'll be honest. I like my A700... and I really want to love it. But this concerns me overall, especially in lieu of the TF700 being right on the horizon. I've PM'd a couple of folks who have received their TF700's & asked them to run the same benchmark above. Hopefully one is willing to help and will provide results soon.

I just played 20 minutes of Max Payne without issue, and while it got warm it was never scorching just warm. Watching HD movies barely makes it warm... I've never had this reboot either, maybe it was the ROM upgrade and rooting/removal. Good luck with whatever you decide.

Well I just had my first freeze.

And that was during the process of moving icons on the home screen!!!

The whole screen just turned white with vertical lines all over the screen, back panel was super hot when it crashed...

It's going back to the seller. Screw this.

I'll run the test here's but just as a reference before I do my 470gtx on my desktop runs 90-95c regularly, nvidia nething are notorious for being hot, and that's with a full sized heat sync. I'll update in 30

55 base to 69 on stress after 4 min.

Sorry for multiple posts can't edit from tablet and I'm too lazy to get up, but I ran it for 30 mins and went from baseline to 87c, not too bad IMO, yes warm but as I said before, my full.l sized gpu on my desktop runs hotter and is fine. I think people are overreacting to this situation, if the warmth really bothers you I understand, but its not a danger at all.

Not a danger at all? I don't know about your desktop GPU, but videocards should definately not get hotter than 79 Celcius degrees!

Besides, we're speaking of tablets, which should not get as hot as a desktop pc I reckon.
And if they should, they sure should not have to crash and get really hot at the right side.
I'm thinking about returning it. It's like Beknatok said, I like my A700... and I really want to love it. But this concerns me overall!

56°C Base
Temp after 6min 65°C
Nothin special with mit Asus TF700T.

That sounds fairly interesting. Do you mind trying it again whilst charging?

New test:
Baseline: 51°C (It looks like it couldn't really find the Celcius degrees since it was around 59°C at first but dropping real quick constantly.)
**stresstest running for 6 minutes**
Temp: 85°C and dropping real quick again to ~70°C and then to 62°C

The back didn't get as hot as last night, when I've had my tablet flat on the bed playing a game whilst charging (80°C with a crash).

**another stresstest running for 6 minutes** -- Couldn't finish the 6 minutes, crashed after 5 minutes and rebooted..
Temp: 76°C

Again, the back wasn't hot. It sure was warm, but not hot.
