Change fan thresholds

[crytic]

Hey there again,

I hope I am not asking something answered 7 times before, but I didn't find anything.
My Xenon, which I finally got working, runs pretty hot while idling in the dashboard (CPU about 80°C, GPU about 67).
If I use freestyle dash and crank the fans up to 11, obviously the CPU cools down pretty fast. Also the box gets _really_ loud now
So is it possible to not hard code the fan speed to 100% but change the thresholds by which the box accelerates the fans?

Thanks for reading,
crytic

360FlashTool 0.94..now was that hard?

[crytic]

Thanks alot man, again!
And no, it really wasn't hard!  

EDIT: Changed the temps to 70-75-80. The box now is only a little bit louder but much cooler. Thanks again!

[ReverseAffect]

good deal...glad it worked out for you

I have another similar question and I know how to edit the thermal settings and manual speeds in 360 Flash Tool 0.94.

But is it possible to increase the idle setting from the stock 5.4v to a more sensible say 60% and still have the auto function take over when the thresholds are met?
This would allow for better cooling all round without the fans roaring but still keeping watch when ambients/loads increase.

I generally run them at 70% but in cool conditions it's probably a bit high, likewise in hot weather you still have to manually set them higher but ingame you don't really know where the temps are at.

Just set the temps for 060ｰC;060ｰC;065ｰC  -  080ｰC;080ｰC;082ｰC. It might be a bit loud, but it's not so loud as it was keeping 100% fans all the time and make sure it will never get past 65C.

Another advantage is that the fans keep the temperature constant, causing less mechanical damage due to temperature fluctuations when the GPU processing load changes too frequently.

Just don't mind the noise and the system will last much longer than it would even with the fans at 100% all the time because then at 100% the temperature would still float from 45C to 60C all the time.

Ok, thanks for that. At the moment I probably have the thermals set a bit low (50,55,50 - 65,75,70) due to the fact that my jasper, since new has had worse than average gpu temperatures. eg. at stock speeds 45/65/60 for cpu/gpu/edram and generally when manually set at 70% the gap is still there: 40/55/50.
And that is at normal room temperatures. Is the gpu a "hot chip" like was mentioned in another thread or a combo of maybe slightly cooler than normal cpu, making the gpu look bad.
I have been loath to redo the thermal paste at this point, some say they notice little change.
It seems a bit unusual to see the gpu hotter than the edram from other posts I've read.

I picked up 60C because it appears to be a good compromise from noise versus temperature. It's obviously much louder than what Microsoft deemed acceptable, but then it makes the system much more resilient/resistant to heat damage. At this point the last of my worries is noise. As for the second set of temperatures 80Cish is perfect, you have set that too low. It's the panic temperature which will cause the console to shut down. I just moved the temperatures MS consider "working range" for the console and put as panic temperatures, while having 60Cish as operation target. 50, 55, 50 surely sounds too low and you will have the fans running on maximum speed most of the time. I'd say it would be the bottom of the temperature curve as it would be the lowest temperatures you can get with the fans on the maximum speed.

Aren't there any fans available that produce less noise?
I also set it to not pass the 65C but I'll have to turn my tv-volume up now lol.
If someone can point me to replacement fans which procude less noise I'd love to give then a shot.

I think the Talismoon fans are quieter, although I've not tested them : I read it in a review.

[Arakon]

I used the talismoon whisper fans and they're in fact a good bit louder than even the already loud stock fans.

[Haygar]

Ok, one last question. I'm aware of the config areas where 7F is for auto or 80-E4 for manual 0-100%, but does there exist a value/location where the stock idle value is set?
My idea is to increase this from the stock ~45% to around 60% for idle and set the thermals to take over when/if those limits are reached, retaining the auto mode but with a more reasonable idle fan speed.

[l_oliveira]

No such thing exists, because what the fans do on automatic is attempt to maintain the temperature constant on the processor over the time. 

To reduce noise, MS set it up so the target temperature would be the absolute maximum ratings allowed by the chip manufacturer.
Which IMHO is really why the XBOX breaks down so much.

So basically you're going to end doing exactly what MS did and caused them so much trouble. Again, just for reducing the noise.

So I wonder what sets the 5.4v on the fans at startup?
I thought since we have so much control on the fans and they can be set below 5.4v that this was possibly another value that we might have yet to discover.
The noise isn't an issue with me, within reason. I was wanting to increase the noise/speed by having the minimum speed at ~60% and still lower the thermal target settings to around the suggested 60C and 80C for the extremes.
My whole purpose for this is I find even in cool conditions I still prefer temps to run cooler than stock but if I set the thermals as above the gpu/edram will be running hotter than I would like under light loads. Whereas if I set them lower it will take care of this problem but the fans will be screaming under heavier conditions.

I think otherwise you will still get temperature fluctuations between the idle temps and up to when the target temps are met, or am i missing something here.
I guess your telling me not to worry about it as long as the high end of things is taken care of?

Ya. That's all you have to be worried with. If you run them at 60C they will be stable at 60C all the time (like an normal desktop PC). If you run Gears or some other heavy load program (XexMenu seems to crank up the GPU clock purposely so it causes the GPU to heat up as well and is great for testing this automatic fan behavior) you will notice the fans speeding up which means they're working harder in order to keep the temp at 60C.
