I don't think a whole lot of people have messed with this feature.

 You should give it a go and see how it works , then write us up a tutorial or just report back with what you found. I personally just edited my config too have the fan run at 75% , in my opinion it is about keeping the system running as cool possible and picking a fan speed would be easier than adjusting it and tweaking the various temp settings to get the desired result.
 
 Play around with it and report back , I would be a little leary of trying brand new features but that is how they get tested.

117C, that would be 242.6F which is probably where the 360 turns off, ive tested the heatsinks up around 215 when it whet 2 red lights.

my question is who did this fan controller? did they think they where working on a car? or where they just brain dead?

you should start with about 35 and end at about 70 if you can control by altering those temps.

I understand what you mean by ex-RROD but both of my boxes are repaired Xenons , i actually favor the Xenon MB don't ask why  but i have always had luck with them (knocks on wood). I will be adding a little post on my website today about some mods i have done to my Jtagged system. I just added a fan off an old P2 the other night , I hooked up a pin header to the unpopulated header on the front of the board , that little fan is quiet at 12v and it keeps it at least 15 degrees F cooler. The fan is just slightly larger than the grill that comes off the heatpipe on the GPU heatsink so i only attached it with 2 of the mounting screws , and i did attach it too the GPU heatpipe grill I thought that would be an effective place since the heat from the GPU heatsink travels up through that and it does work very well. I think it also assists with the CPU a little bit being in such close proximity , i was getting the CPU down too 140F where it is normally 150-155 , I have my fan running at 75% because at 100% the noise is unbearable for me.

 I have to do everything in F temps because i am an American and C just doesn't register in my brain , like seeing 45c i can't think of how hot or cool that would be. Anyways my CPU gets up too 150F but my GPU stays at 115 during games and the same with my ram. They were much hotter before I added that tiny fan. But i could have sworn my CPU used to stay much cooler than that.
 
Edit: I forgot to mention that i upgraded the heatsink on my GPU this is why i have the heatpipe on a Xenon GPU just to clarify that.

its just the 45 minute LPT nand flash i cant be facked with. i'd like to know what these settings mean first

thats just the config your editing, just flash over the config thats on there.
nandpro lpt: -w16 config.bin 3de 2
should take 5sec.

i have a idea of how those temps are used to control the fans but i will have to test it, probably in the next few days.

thanks for the explanation man! yeah its all in C over here rather than F. some one decided that was the way it was gonna be over here at some point before i started school!

i have shome rev 2 GPU heatsinks in te post, as the temps are just too high. then im looking at extra fans which i can poach from work. do you have holes cut in your case above the fans?

  No i did not make vents yet , this was a 3am i am bored let's mod something mod. I cleaned it up last night. I probably will add a grill in the near future , except i also managed to knock off a MOSFET under the GPU trying to put x-clamps back on it and have to get a new Jtag. I suposse i could do the same to my LIVE box but I don't have a way to check the temps without spending money on a thermometer.  That is the second system i have done that too so i am going to stop putting x-clamps back on them.

 I am interested to see Grims findings on the temp settings. It's too bad we can't re-encrypt this stuff and use it on non-Jtaggable systems , without the CPU key at least.

 I know this is not the place for pictures but here is the rough draft i guess of the tiny fan mod. The electronics wholesaler around here carries fans small enough too attach to the ram ships I am going to try some of them too. This one i just ganked from a P2. I couldn't get the pins to go down into the holes very well but that is a solid and stiff connection none the less , but i am not happy with it coming out of the board that much.

[7urrican]

cant believe i didnt see the tooltip!  

well thats that then. my boards are all xenons so i guess i'll want the target temps a little hotter. i have fans the right size for the GPU sinks when they arrive, so i think i will be copying your mod and maybe cutting some case holes above them.

then i will experiment and decide on target temps. any ideas what these should be for a properly cooled xenon?

thanks for the help and ideas

[Grim187]

i dont even have the tooltip on mine, weird.

anyways heres the original temps for the different board versions

xenon:  080°C;083°C;085°C  -  100°C;110°C;117°C
zephyr: 080°C;075°C;078°C  -  100°C;100°C;102°C
falcon:  080°C;075°C;078°C  -  100°C;100°C;102°C
jasper:  080°C;071°C;073°C  -  095°C;090°C;092°C

xenon v zephyr is kinda odd since the only change is the 90nm gpu was swapped with a 80nm, but they lowered the gpu and ram temps quite a bit.

im gonna try this on a xenon
050°C;053°C;055°C  -  075°C;073°C;078°C

 If you hook up a fan the way i did you have to bridge some points close to it for it to run , their are 2 sets of pads on the bottom side bridging 1 will make it 5v and the other is 12v , I hooked it up as 12v and it is not very loud at all , not with the stock fans running at 75%. It may run without the points bridged but it would be very slow and the noise at 12v is not very noticeable.

 If you do add the vents get some pics up , i am looking at tuesday or wednesday of next week before i will have a new Jtag , i suppose i can mod my case still though , but the fans don't run so i can't get a video. I also don't know if i will be getting an HDMI or Xenon board , my case is a Xenon and painted.

your temps "Delta stock fan values are 45/54/56 at 5.4v (idle)." is this with the 5v GPU fan?

No, without GPU fan.

Did you used any "donor" nand images (from friends or internet) as source to create your freeboot image? They include individual calibration data. If so, your values may be wrong.

Maybe thermal paste or temp pad is lost under the cooler.

Those 45°C Xenon values are aggressive/loud 12V coolings or advanced solutions (like watercooled).

My 2006 Xenon -

080°C;097°C;100°C  -  100°C;110°C;117°C

My  2007 MS repaired (gpu heatpipe extension) Xenon -

080°C;075°C;078°C  -  100°C;100°C;102°C   (same as the Zephyr)

 So wait are you saying that MS changed the settings on it when it went in for repair? And that they changed them too the same as the Zephyr?

[7urrican]

ive been busy! my GPU heatsink showed up so i fitted it and a fan for it which is quietly running on 7V, which seems to be perfect. i have talismoon whisper fans and i ran it on bioshock 2 for a while then looked at the temps.

62, 52, 47

so after a bit of tweaking i decided on these settings for flash dump tool:

065°C;060°C;058°C  -  080°C;075°C;073°C



its behaving quite nicely so far. i just taped up all the holes around the air tunnel, and also chopped up an old dvd enclosure and internalised my 1TB HD. this is a bit of a mess (you can see the drive lolling at an angle!), but it fits nicely inside now.

next is to cut a vent for my gpu fan in the case. i was gonna use my XCM smoke black case again, but i have decided that it is so utterly abysmal that im gonna go back to the original case.

[Maximize]

I think it would be sweet if someone could find a way to show the temps on the menu when you hit the guide button in game, because if I play a game and then go to xexmenu by the time I can get the temps to show they are back or just about back to there baseline.  Im sure it will happen someday

[Haygar]

SilentBob1638,
Nah, I have my own original nand dump which I confirmed ok with matching dumps and only had to remap 1 block from 41DF to 3C12.
Now have freeboot running but nothing has changed in regards to temps from when xbr3 was on.

As for thermal contact with the heatsink, not 100% sure. I jtagged this straight out of the box in january and it always has showed, what I feel is a bit higher than avg. temps. They look good here but it is under ideal cool conditions, for the console not me, lol.
I'm not willing to f^#k with the heatsink/paste yet till I work out a bit more of the config areas, also thinking that it may be a manufacturing tolerance thing to do with the sensors themselves in the dies?!

Here is some info on some tests I did between the kid's falcon (2 years in service, heatsinks untouched) and my jasper:

Conditions - Ambient (a cool) 17C, fans @ 70%, no dvd drive inplace, no cover and cards placed over top of gpu and cpu to simulate normal airflow, idle in xexmenu.

Jasper      (readings in xexmenu)       (readings with IR temp gun)

CPU          32.5                                  29.0 (R/H front corner of heatsink, highest reading I could find on it)
GPU          45.7                                  40.7 (Heatpipe @ top of extension,     ''         ''       "     "      "   "   ")
                                                        35.0 (Main gpu heatsink,mid front where the screws are, " " " " " " ")
EDRAM      40.4                                  N/A  (Hard to do, heatsink shows low 20's, poss. due to cool airflow)
MB            24.5                                  23.5 (Just point and shoot @ southbridge)
Exhaust temp, gun aimed @ GPU fan    25.2


Falcon

CPU          34.4                                  28.3 (Same as above)
GPU          38.3                                  43.0
                                                        43.2
EDRAM      43.7                                  N/A
MB            29.0                                  30.5
Exhaust temp, gun aimed @ GPU fan    25.0

I also have been taking note that when warming up both the gpu and edram temps climb at a pretty even pace, and keep around the same temp gap making me think that the contact to heatsink may be fine.

Unfortunately it still doesn't tell me what is going on with the gpu,whether it's just a calibation thing or real.
The falcon is doing pretty well up against the jasper.
I know the readings are all low but this is in pretty cool conditions and I have seen 70+ on the gpu when the ambient was high with stock speeds. I actually heard the fans speed up when it got to 70.9, makes sense now if you look at the config area 80,71,73.

What would be great would be if anyone can post their jasper config in 360 flash tool or somewhere that already has to compare with, a donor config or even just the gain/offset values.

I might also try editing some of the config for shits & giggles and go back to auto but 70% seems the sweet spot for noise vs cooling.
Otherwise I doubt at this point there's much to worry about, but where do you edit the idle speed?

Edit: This all looks messed up now after posting. Readings were layed out better when I typed it but have to go now so no time for full edit, sorry.

[fahrenheit]

Are you using Xexmenu 1.0?

[Haygar]

No, xexmenu 1.1. Was using xexloader B4 that. edit: I get the same readings in freestyle 1.20

What are the gain and offset values actually doing?
These correspond to backup values? I don't get it.
