Tronsmart T428 thermal problem

Mine is also overheating
It looks like mine also has the overheating problem. I ordered it from geekbuying.com, it arrived yesterday, and it's unusable.
It runs for a couple of minutes, then reboots. I tried the Antutu benchmark, and it won't make it past the CPU and memory test. It gets to 1% then crashes. It's then very unstable for a couple of minutes (presumably while the CPU cools back down), sometimes not even making it to the desktop before rebooting. The longest I had it running was maybe 10 minutes before rebooting.
I'll be returning it and getting a refund, as it's obviously not fit for purpose. I'm certainly not going to start hacking holes in the case and fitting heatsinks to a brand new device, when most people are not having problems with theirs.
I've tried the supplied 5V 2A supply (geekbuying were kind enough to supply a UK adaptor, thank you), a Samsung Galaxy Tab charger also 5V 2A, a Nokia 5V 1.2A supply, and the USB output on the TV which is rated 5V 1A. None of them seems any more or less reliable than the others.
Is there anything I can do to monitor the CPU temperature before it crashes? I would like to see what is happening to the temperature right before it reboots, as I suspect it's temperature-related rather than power-related.

I would definitely measure the temperature that is higher than 50 ° C, you've got a problem.
If the temperature is not so high to change the power supply,but with min 2A output
My stick goes here now great and I have no problems with the power supply (knock on wood)

Stock power supply & no problems ever since I got it.

I just installed an aluminum heatsink (the one I mentioned in an above posting). It is 20x20mm with an adhesive backing.
Here it is applied to the RK-3188 SoC:
and this is the re-assembled look:
It looks a little rough and I did have to dremel out a small slice of the metal trim piece that is sticky taped to the side of the case, but airflow shouldn't be a problem and I can even use an ordinary household fan to blow air on it if need be.
I don't detect any performance improvement since I installed this heatsink, but I should be ready for any ROM that comes along that lets us crank these RK3188 up to the max clock speeds (1800MHz cpu & 600MHz gpu). Also, from what I've read, if you're running a real 1080p kernel on these sticks, the SoC can get real hot, so a mod like this may be necessary for that. Anyhow, it should help longevity.

Taking apart the T428
It's clear that Tronsmart is employing a "tamper-resistant" case design now. I understand why. If the cases are easy to open, people go in there and start popping off static discharges and frying everything in sight, then they want an RMA and a refund.
It's still not all that difficult.
1. Pull off the metal trim pieces on the side of the HDMI stick. They are just sticky-taped on.
2. Carefully pry apart the plastic top & bottom halves of the shell. They just snap together, but it's rather hard to pry them apart without cracking plastic. Using a small flat-blade screwdriver helped me.
That's it. There are no screws. The circuit board just kind of snaps into place. You'll want to pull up the HDMI end first and slide it forward to get the rear USB & Power ports out of the plastic end cap.

Same here

the device was piping hot, damn near too hot to touch.
i cracked it open to cool off faster.
the 908 has a heatsink covering an entire side (and chip I assume), but the rubberized case was inhibiting airflow across the heatsink, rendering it useless in my opinion. heatsink was scalding hot.
I accept that and don't blame anyone because im using the 1080p Kernel. Tronsmart didn't have to supply that ROM but they did just to be cool. Im just going to rigg up a small heat sink to it and not worry about it anything after that. I think future devices should just use the Minix X5 form factor and put a small fan inside. Few people actually care about the stick size. I always just set it on top of my blue ray player anyway. Look at Ouya they added a fan later on too. A heatsink and fan give you much more flexibility in the future if you want to run more demanding apps or over clocks a little.
I would love to see some one supply a heat sink and fan that snaps on to half MK908 case. Id be fine with paying up $20 to $25 for that.
