I'd like to report some updates about this issue...

1. the fan issue occurred again, so I tried FSD3 to change speed, then I found it doesn't work at all...fan just won't spin!

2.what worse is the next day, it won't boot up...cannot enter Xell either(I don't even know if Xell is there or not, nevert tried that...)

3.finally I  bought some dissembling tools and opened my xbox... found: 1) it is a very cheap J-Tag chip; 2) the fan deson't spin at all when powering up.

4.it looks if i was willing to going further, I may have to take a soldering course and will very probably make a lot of holes in the board, so I gave up and sent it to the repairing service.

5.the reparing guy told me the issue is some wrong soldering and J-Tag needs to be replaced. 2 days later, he sent back the xbox and looks it's OK now...

So, it looks like just a HW issue

I don't know what homebrew stuff was intalled before I mess with it, I'm still wondering if it is because some jumpers or anything is not compatible with new SW and need to changed accordingly...anyway, I can play the games again.

Thanks again, Swizzy

hey, thanks Swizzy I have updated avatar as well.

however, regarding the fan issue, I didn't even think of messing up the fan settings before I met the overheat....

I still have these questions: 

1.would installing DL3.17 or Aurora 0.5 change any SMC_Config data? if yes, what are the changes?

2.is setting SMC_config in DL3.17 installer tested in corona and confirmed working fine? because in my case, it seems changing SMC_Config in DL3.17 installer works OCCASIONALLY. And no matther how I config it, the next day I would still not hear the fan spining.

and seems I'm not alone - this guy has the same story:

"I have a rgh corona v2 running F3 and noticed the auto setting doesnt seem to do ANYTHING in terms of changing fan speed. My xbox overheated the other day on the auto setting while playing a game. The auto setting, which is seems to be just the lowest fan speed (10% or 20%) Auto is okay for less intensive games but its dangerous for anything else. For some reason 65% is the next highest setting and it keeps everything cool but is too loud. I'm going to play with dash launch settings. My guess is 50% fan speed or a target temp of 60 is a good combination of temps and fan loudness."

Swizzy, I flashed the Nand you gave me and yes, the issue is gone!!!    

however, I'm still puzzled:

not sure how I had those fan speed set as in DL i don't see any "Auto" option there...and how would that cause overheat?

I wish to keep digging and find out the root cause and make a conclusion

Hey thanks, Dr.Gonzo ;-)

I found the part you mentioned looks like I just generated a new flash...

however my main concern is on SMC_config, and when I try to check SMC_config from the flashdmp, I got an .net exception...

I don't know if that is relevant at all, but that does make me wonder -- is setting SMC_Config in Corona 4G different from other motherboards somehow?

I don't know if it's a coincidence but I met this overheat issue not long after I installed DL3.17.....just some wild guesses, for your info

just had it dumped, and tried to open it with XeBuild, but seems the nand is corrupted or something that I got the error message: unable to determine dump size(it's 48MB actually)

some other info I got: cpu key masked.

do you still need the dump or perhaps I need to update the whole nand? 

is it possible to build a nand with these info only?

You are awesome, Swizzy bro!

I haven't touched the nand thing yet but I'll study it right away and get the dump.

I'm really surprised to get your support as I didn't expect much... I really appreciate it.

I really appreciate your prompt reply, and thanks for placing the post in the right place, Swizzy. --actually, I was thinking over about your ideas:

1. I'm positive that fans are working, as they always work 100% as expected in the 2nd time I startup it;

2.the sensor in the cpu is probably broken?   you mean the temp sensor?  I don't think so as I can always read the correct temperatures.

the funny thing is that it looks like those fans are frozen or maybe 10% speed(?) when I power on my xbox, for some funny reason, it's either

(1)the fans cannot read the settings from SMC_Config so they work like some "factory mode"

or

(2)fans manage to read the SMC_Config setting but cannot spin up(not enough voltage in the beginning?)

What's extremely interesting to me is the difference of 1st startup and the 2nd startup(or reset), what happens in NAND/BIOS/HW/anything that matter during the forced shutdown?

any ideas?

and would upgrading kernel worth a try or just a waste of time? 

Hello all, this is my first post here. 

here's some useless nonsense in case you have too much time:

I have Auroa 0.5+ DL3.17+ system build 16537, set target temp to 60/60/60. and here's the symptons and other hints:

          * the issue occurs almost every time I startup my xbox: every time I start it up, I call the blade and watch the CPU temp goes to 90C and then it is forced to shut down;

          * after I start it up again, the temperate and fan speed ALWAYS works as expected.

          * I guessed it might be caused by lauch.ini not loaded correctly, but later I confirmed there is only one lauch.ini in the console and it's 100% loaded correctly.

          * I tried to enter DL during the 1 startup: I can see all temps are set correctly and it's just getting higher and higher above the taget temp. I tried to override the fan speed directly, but the funny thing is that it's not working at all: I can't hear any difference and it still getting hotter;

          * however, when I enter DL during the 2nd startup, tried to set fan speed, it wasn't working in the begining, but very strangely after I tweaking for several times, it began to work!

I really don't know why I have such a funny issue, no idea about the root cause, so before I try to upgrade the flash and screw everything I wish I can get some clues from professionals.  any idea is sincerely appreciated.

Happy Halloween!
