AML S802 case modding - Show your mod's to cool it down :-).

[HwGeek]

Hi all :-),

I saw the problem with this S802 boxes- They get really hot and the performance drop :-(.
Have you mode the case to improve the cooling effect? - please share your mods :-).

I got the Tronsmart Vega Tronsmart Vega S89 Elite and it's really stupid design for it's SOC power.
It has no ventilation holes! -now I see more and more S802 devices getting problems because of the overheating- so I don't like to wait for the day it will die -this is why I thought about this Mod to make it look like Stock - adding 2mm spacer to the bolts hoes so I get 2mm gap between the bottom case to top case- 360 deg ventilation hole :-), the cold air will enter from lower front gap and exit from rear top gap :-) -what do you think?

If I receive my device I will make the holes (or maybe a slit) on the side as close to the top as possible...

This and the next posts discuss about thermal past

enlarging the bottom vent holes may help...

-what do you think?

I think that while being better than nothing it won't do what you're expecting it to do.
Without something like a fan to pull/push the air through the narrow slit, you won't have the expected circulation.
If you intend to make use of natural convection, the way is to make sure you have a proper thermal conductor in the form of paste/glue between the chip and the heat sink (which should also be with proper surface quality on the bottom) and drill a few holes right above it (and beneath it as well)

Can't quite quantify the expected effect, but i do believe it's the best thing can be done with the given conditions.

Hope Hong Kong is paying attention and learn from this !!!!

I also noticed that the round box (in my case Mbox S82) has very poor ventilation. I tried to monitor core temperatures under stress with various apps, but none of them seemed to give reliable results. Most of them show only "battery temp", which is always 30C. Some apps also show "core temp", but the readings don't seem to be correct. I am using Finless Bob's 1.6 ROM. Does anybody have an idea, how can I see real core temperatures?

I was having crashes while watching Vimeo HD videos via browser, and I thought it was caused by over heating. I found out later that it was just an software issue and Vimeo works fine with Chrome browser.

Anyhow I decided to do some modifications. I opened the box and measured temperatures with my IR temp gun. It was obvious that the contact between CPU & heat sink was really bad as the heat sink did not get that warm even under heavy stress.

I removed the heat sink and as you can see from the picture, the heat pad had only partial contact with the heat sink:


I modified a new heat sink from some old cpu cooler by drilling necessary holes and lapping the bottom straight with a glass plate & wet sand paper. The new heat sink has much better structure for passive cooling, and it is bigger as well (I think it was 16 grams vs 34 grams in weight). I applied the HS with some silver paste and fixed it to the board with nylon screws & nuts.

I also modified the box by drilling multiple small holes to the bottom and one large hole to the top. I glued a fine aluminium mesh to the top hole to make it look better.




My modification seems to be working well. The heat is transferred to the HS and I can feel warm air rising from the top hole. It even looks pretty nice. Bigger HS and better ventilation will handle the heat easily and temperatures are staying low (i would still like to see the real core temps though).

That is a great looking modification

Like the big hole, looks great with the fine aluminium mesh.

Thanks! This is quite simple mod to be honest and it can be easily done with some basic tools. The most difficult thing was to get the PCB back to the case. I was surprisingly hard and required some force. I was afraid of breaking the board while doing it.

If somebody wants to do the same mod, the fine aluminium mesh is used in car repairs to reinforce glass fiber parts while repairing cracks. It is flexible so it can be formed to dome shape just by pressing with finger after the mesh has been glued to inside of the case.

WoW Amazing Job!

Thanks! I actually tried this before modding but the temps were jumping weirdly. Now I tried it again and it makes more sense. Maybe the bad thermal connection caused weird readings. I tested with multiple benchmarks and 75C is currently highest reading with antutu stability test. With most benchmarks 60-65C is top. Which app is most demanding in terms of heat?

Be aware that if you're using 104k4/Fin1.6 you may have false/unreliable/crazy temps reported, don't be too confident in them...

See my MSI agp 8x mod




I'm not particularly MSI fan, I just had 2 old southbridge heatsinks in stock, I had to place them strategically to be able to close the box again (can't see MSI when it's closed)
Sure there's not much contact between stock and screwed heatsinks (used some thermal paste though), it's still passive with no new holes, but it seems to be effective (about 10°C less in both idle/burn) and more inertia makes temperature to rise much slowly. More, I feel the heat is well spread on sides of the box, that was the goal.
