Now that many of us are able to see our xbox 360 system temps via software due to the release of the awesome XeXMenu, I thought it would be good to have a dedicated temperature thread.

If you are able to measure your temps in any way, please state what method you have used to do so, and any other relevant info, like any cooling mods you may have installed.

Try to stay on topic and stick to the formula below.

Nice thread thanks for the info!

Xenon

Idle
CPU: 78.5C
GPU: 71.1C
EDRAM: 74.1C
MB: 36.2C

My GPU seems to top out about 75C

Played some bayonetta for half an hour didn't make much difference to the temp.

on an xenon with the new type GPU heatsink and xcm whisper fan (50% more air my arse!!)


Now at least we can all see what cooling mods actually do anything...

As the xbox360 CPU is based on the powerpc chip from IBM similar to that used in the G5 so we could assume that the temperature properties are going to be similar. The G5 had a nominal operating temp of 160 C which is 71 C. and what we are pretty much seeing with the xbox. The top rated temp I can find for a PPC chip is 105 C or 221 F. Smokin

But then the G5 had some enourmous heatsinks and cooling systems, I remember the top model was watercooled as standard.

Taken from the other thread..

Xenon with 7v fan mod, Wilhelmis Hybrid advanced uniclamp, 7v fan mod and the metal fan grills cut out.

Idle.

Cpu 61.4 Gpu 61.7 EDRAM 59.3 MB 30.5

First I'll start off with cooling mods:

AS5
12v mod on just the GPU fan
duct mod with divider

I'm also using the stock heatsinks(old style GPU heatsink). I'm a little confused on the way the xexmenu temps work. It seems my temps always start low and count slowly for ~7 minutes before they level out. This makes it easy for me to get idle temps, but gaming temps aren't practical using this method. If I have to wait 7 minutes to get my temps they're no longer the same as they were while playing the game. Here are mine anyways.

Idle: (xenon system)
CPU: 70.0
GPU: 60.0
EDRAM: 60.1
MB: 29.3

46°C / 47°C / 50°C /32°C
At my almost silent 120mm fan mod jasper.
Temperatures rise about 2°C after playing Assasins Creed for 30mins and switching back to xexmenu.

I'll just copy and paste what I posted on the xboxhacker forums.

Model: Falcon (later version with only 4 RAM chips on top of mobo)

Temp1: CPU:59.3C GPU:73.2C EDRAM:78.0C MB:35.0C - idle in XeXMenu config screen
CPU:57.4C GPU:64.6C EDRAM:69.3C MB:30.7C - idle in NXE

Temp2: CPU:60.5C GPU:73.8C EDRAM:78.8C MB:35.3C - Tomb Raider Underworld 30min

Temp3: CPU:59.8C GPU:69.1C EDRAM:74.2C MB:35.7C - Stable after 30min+ of gaming

Cooling modification: Talismoon WhisperFan

Ambient temperature: 23.5C

Other info: Console kept vertically, Microsoft HDD plugged in, displaying via HDMI @ 1680x1050, no cooling mods other than Talismoon fans running at stock speeds.



UPDATE: I have now done the fan shroud mod and run the same tests (missing out temp 2)

Temp1: CPU:59.0C GPU:71.5C EDRAM:77.4C MB:34.9C - idle in XeXMenu config
CPU:57.5C GPU:62.3C EDRAM:67.9C MB:33.5C - idle in NXE

Temp3: CPU:57.9C GPU:65.5C EDRAM:71.5C MB:33.8C - Stable after 30min+ of gaming

Ambient temperature: 23.9C

Conclusion: Doing the fan shroud mod looks to lower temps by 1-2 degrees. However, it is difficult to get accurate temperature readings since they change so quickly when going from game to XeXMenu to NXE etc. I used the guide button and recently played menu to navigate to XeXMenu as quickly as possible to get my readings. Also, Talismoon fans don't appear to be any more efficient over the stock fans.

I rechecked the temps on my system while it was sitting vertical. Here were my temps:

Horizontal
Idle: (xenon system)
CPU: 70.0
GPU: 60.0
EDRAM: 60.1
MB: 29.3

Vertical
Idle: (xenon system)
CPU: 72.7
GPU: 62.0
EDRAM: 62.0
MB: 29.1

So mine seems to run cooler while sitting horizontal.

Started a temp thread in the hardware forum. It got closed.

copy paste from there

After putting the dvd drive back into the system, I guess I must have increased airflow even further because GPU temps went down to 46-49C Other temps remained the same

According to this modding the fan shroud to increase the air pressure over the GPU lowers temperatures dramatically!

Possibly my EDRAM seems a little on the high side

Ahh, I guess I should provide mine for entertainment :-)

My system appears to run quite toasty. I should leave it open and use it for a foot warmer ;-)

good god you need to do something with that box asap! If not, you can expect a rrod very soon

took out the DVD drive and put a 80mm fan on top of the GPU heatsink and the GPU temp is down to 55c idle

temps before :

CPU - 80
GPU - 71
EDRAM - 70
MB - 30 - after 30 mins idle

It seemed that my Jasper512 was running hotter that it should when comparing to the figures posted here. My gpu ran at about 65C with CPU at 45C

Then i applied the following cooling mods

I added a fan ontop of the GPU heat pipe. That brought the GPU temp down to about 59C. After that I added the fan shroud partition and a piece of cardboard ontop of the GPU heatsing so consentrate the airflow. Now my temps are a follows:

CPU 41.1C
GPU 49.3C
ED 49.5C
MB 36C

Ambient: +-20C

Did not want to do the 12V fan mod coz of the noise, but the mods i did removed about 20C from GPU without increasing the noise

Heres my readings on one of the new Falcons i bought, both stock and then modded with my mod


Falcon (Brand new - refurbished
16mb, with the stock heat pipe

Idle
CPU: 59.2C
GPU: 74.1C
EDRAM: 73.7C
MB: 34.2C
Fan voltage 6.1 (measured across the fan wires).

After installing the mod


Idle
CPU: 49.6C
GPU: 52.1C
EDRAM: 54.2C
MB: 32.4C
Fan voltage 7.2v (measured across the fan wires).

Its important to note that MS deliberately slowed the fans down so that the 360's remained quiet so as not to irritate owners. If they were to have run them faster and cooler i would imagine there would have been a lot fewer deaths

The mod info can be seen here. All the ones i have modded have similar improvements without the fans going full tilt... The fan idling speed can be set to whatever voltage you want


http://forums.xbox-scene.com/index.php?showtopic=703046

I have a Xenon with stock fans and no mods to the GPU or CPU at all. Original XClamps still in place.

Here are my readings at idle,

CPU 80.1C, GPU 92.0C , EDRAM 99.8C, MB 38.9C

After seeing these temps I applied the "FanSpeedFlasher" app and did the "70speed.xex" file. these were my speeds at idle 30 min later:

CPU 80.0C, GPU 93.0C , EDRAM 99.8C, MB 38.2C

Ouch!, that looks bad, thats a RROD candidate for sure. I would definately start by removing original clamps and doing the xclamp mod

Hey just so you know fanspeedflasher doesnt work correctly on most systems. you are better off doing the manual 12v mod

INFO:
Model: Premium (Xenon)
MFR Date: 09/02/2007
Time in service: ~ 2.5 years
Usage: Light
Cooling: Stock
Temps read via: XeXMenu v1.0

Room Temp ~ 20C

20 mins XeXMenu
CPU: 79.9C
GPU: 81.2C
EDRAM: 79.8C
MB: 32.1C

Replaced X-Clamps (as a preventative measure, it has never RROD'd), thermal paste replaced with AS5 (CPU+GPU).

Just did the fan shroud mod. It appears to have lowered the GPU temp with about 4-5 deg C. It maxes out at around 77 now.

And now:

Xenon with gpu heatpipe type heatsink.
Fan shroud divider mod
Talismoon whisper fans (at normal speed) (run fan speed flasher but doesn't seem to make any difference)
Foil extended shroud
XCM core cooler running at 5v (angled towards the gpu heatsink)

temps after an hour or so idle in xex menu.

CPU 79.0c
GPU 63.1c
EDRAM 68.7c
MB 37.9c

Quite happy with the GPU temp which is down from its previous score of 75c but not so happy with CPU temp.

So some adjustment required I think.

Not sure the shroud divider mod is really going to do anything as there is a big gap between the fans and the MB to suck air out of the underside of the board as well. Can't see that adding the divider is going to force any more air through the GPU heatsink myself. without blocking this gap which will prob lead to other problems.

I find the same as you. My jasper is brand new 28/4/2009 and at start up the gpu is around 10C higher than the cpu then stabilising to 20C above the cpu after a while. Still stock at the moment but I want to look at firmware/software modding to keep it under control, like the xbox1.
It had nidec fans but I swapped them for some new deltas that I had set aside. Slight more noise but better imho.
Falcon with 9v mod runs cooler all round.

Wish I could find more info on editing xbr to permanently increase fan speeds or the monitoring of them. I am guessing this will come in time in homebrew. I used to play with sensors combined with a control circuit attached to the heatsinks to regulate the fans and this worked well. But now we have a direct source this can be the ultimate solution.
I am surprised by the varying results on temps but kipper2k,I agree with what you say about MS and they kept the fans slow to bring the noise down.
And also you're right that a small increase in voltage will give a relatively big increase in temp drop, especially on the gpu.

Like I would expect!
That app does nothing from what I've found and others have reported except for messing up your nand.

I am also interested in increasing the fanspeed through software. I'll do the rawconfig.bin edit but there is not enough info about this and success stories doing it are few.

Let me know if you found any info to perform this

Glad to see everybody sticking to the formula

The temp control circuit works good, I dont see any reason to do the 12v mod and have the fans howling constantly or cutting holes into the case and using more fans to try to cool it down. I think anyone who has a cpu temp higher than the gpu is in serious poopoo. The cpu should always be cooler than the gpu. The gap between the cpu and the gpu on the release xenons would not be all that far apart but if your cpu temp is higher than the gpu then its time to take off the heatsink, clean, and re-apply arctic silver and xclamp if not already done so. I could not see myself turning on a 360 if either my gpu or cpu hit 80 degrees. the fans should be screaming at that temperature. A Fan speed control circuit in the 360 is i believe best as it is a gradual increase in speed directly proportional to the increase in temperature so you can get the required temp without running a jumbo jet in your room. You would decide the minimum speed/equivalent temp by controlling the idling speed without the need for going to extremes.

Xexmenu gives the ideal platform now to check all this stuff out....

btw, people with talisman fans, how do these perform, i know they are quiet, but i'm from the old school of thinking that says if a fan is quiet then its not really cutting and moving the air, now with xexmenu we can actually confirm this

Falcon; 12v fan mod, 92mm 12v fan blowing half over the GPU, half on the mobo:

30 mins:

CPU 42.1c
GPU 39.2c
MB 23c

No fan shroud mod.

Going to be putting on variable fan switches in a day or two so I can still play a bit at night without ubernoise from the rear fans. 92mm one hardly makes any noise. I'll probably block the vents next to the hard drive and above on the top of the case, doing that from the outside with tape yielded another 1-2 degree drop.

Edit: dvd drive is external.

Can't say that the talismoon is any quieter or more efficient than the stock fans. There is no point to using them unless you want the lights.

and if they are shifting 58% more air than stock then its certainly not reflected in any temperature drop at the cpu / gpu.

Still looking for answers regarding the temps.
When the ambient temperature was around 23C my jasper was stable at around 45C CPU and 65C GPU.
Ambient temp is now 32C and as soon as I could boot into xexmenu they were around 40C and 50C but after approx 10 mins is now:

CPU 52.9
GPU 70.9
EDRAM 69.2
MB 37.9

Not sure which temp is doing it but after the temps got close to these measurements, you could hear the fans speeding up slightly in increments until everything slabilised. You can still hear them rise and fall just a whisker trying to keep track.

What I want to achieve is the same type of control using an edit in the software but at a higher fan speed to keep the overall temps lower.
Like what you can do in the settings of XBMC on the old xbox1.
Does anyone have any info at all please!

I used these in my old xenon (RIP, died in a heatgun accident) and I always suspected they did nothing of any significance and swapped back to the stock ones after it's first rrod error. They actually draw more current mostly due to the led's and are more of a novelty item than a cooling solution in my opinion, ok for the modders tho but I still swear by the deltas.
Haven't bothered to test the talismoons again since xexmenu, couldn't be stuffed changing the 4 pin to 3 pin connector.

Zephyr MFR 2008-10-29
Has shroud modified and GPU fan running at 9.75 via 3 diodes from 12v rail. CPU fan stock speed, mesh fan grill cut out from metal case. room temp around 18C.

After 25min playing geometry wars, cover on:
CPU: 67
GPU: 56
ED: 61
MB: 27

A few hours later after removing cover and playing halo3 for 20min:
CPU: 60
GPU: 53
ED: 59
MB: 33


It's funny how everything was cooler except MB. It must be that without the cover there is no air being sucked in from the side vents across the motherboard edges.

So after the test and reading this thread it is clear to me that shroud/fan mod is a must even on jaspers.
Also before this I believed the CPU was fine with stock speed but now I see it also could use more air.

So I modded my fans some more, GPU now running at 10.5v and CPU fan at 9.75v.

After about 25 min part idol (installing a game to HD) and part geometry wars:
CPU: 53
GPU: 45
ED: 50
MB: 30

Temps looking good but I noticed they were rising just idol on xexmenu, after 10 min more just
idol on xexmenu:
CPU: 54
GPU: 50
ED: 56
MB: 31

xexmenu more tasking than geometry wars?

For what it's worth I don't have a JTAG xbox yet and the one I was going to for a friend had a horrific accident after I flashed the drive where the video out center piece that holds the pins was ripped apart by THE STOCK VIDEO CABLE, not a forceful tug, just a standard pull(stupid shotty microsoft BS) But before it broke I would leave it idle(didn't play games, that's why I flashed the drive, it needed the correct key, my friend used the original drive on another xbox) and it was pretty warm at first, I left it running for quite a while and it was blowing about cold air and was noticeably cooler underneath the case. I let you guys know what my Jasper is when I get it, one above was a Xenon that I might still JTAG myself but I'm going to have to solder some shit directly to the video contacts on the motherboard

Does anyone know if any of the fan speed apps are ok for Jasper 256/512 nands?

Because the config areas between 16mb @3de and 256/512mb @ef7 are as such, the patches are apparently incompatible with the big block nands. Any info from experience would be great.

With all this homebrew at our fingertips I don't see the need for hardwired mods on the fans now.

Well, after doing a bit of reading and some testing on my falcon and jasper BB, I found an app that works on both.
Found this thread on xbox hacker http://www.xboxhacker.org/index.php?topic=13841.0
Use ddxcb's patcher.rar and apply the patches in there to the autospeed.xex file to modify it to your desired speed then rename it to eg. 50speed.xex for 50% and run them in xexloader/xexmenu also reboot for them to take effect.
Just make sure you read the whole thread so you understand. You have to use the Autospeed.xex off fantools in the _old folder not fanspeedflasher.
What I did was create a folder: Hdd1\Apps\Patched speeds\ and in there I put all my created xex's from 50% thru to 100% including the original autospeed.xex (so you can put back to stock if required).
The readme says it's just for 16mb nands but I backed mine up on my jasper 512 and took my chances and I can confirm it works sweet on all the settings

No more need for fixed wiring mods, yay!
Also I found 7F @ 4211 and 4212 on both the falcon and jasper original configs

I aren't registered on xboxhacker so if your reading ddxcb, thanks for this great little app

New console from M$ (repair center)

Xenon with newer heatsinks

IDLE

What you think ?? fans dont seem happy lol

got a refurb falcon the other day

IDLE in xexmenu, stock fans

RROD ready to happen
gona do some cooling mods then an update!

OK an update, I put an 80 MM 0.25 amp brushless fan running off external power source on top of the GPU heatsink.

new temps
CPU: 44.7
GPU 39.5
EDRam: 45.2
MB: 32.2

An excellent improvement! Much cooler than a 12V mod and as a bonus MUCH quieter!
Now to find a suitable spot on the mobo to run this thing from

A refurb xenon with temps like that makes you wonder if they are putting a 65nm gpu in as a replacement

I used ddxcb's patches to set my fans at 60%. The results are very noticeable!

Before - CPU:59.3C GPU:73.2C EDRAM:78.0C MB:35.0C - idle in XeXMenu config screen - Fans auto
After - CPU:48.9C GPU:54.0C EDRAM:59.7C MB:27.1C - idle in XeXMenu config screen - Fans 60%

The results are impressive. I'm going to keep them at 60% from now on I think. The noise isn't too bad either. Definitely a lot more bearable than a 12v fan mod or 100%/70% patch .

Doesn't this only allow one given speed which would mean that the speed will not increase/decrease with load etc ?

Yeah I believe so. You just get a fixed speed except for the original auto of course.

But it will be cooler, just keep an eye on temps every now and then if your using a low speed setting.

I made 10 threw 100

played 5 hrs straight of me2, fans running at 90

and temperatures were 45 across the board.

Xenon with patched fans running at 80%
is this good by common standards?

I took a bit of a risk myself hoping not to brick my Development Kit using the fan patcher and the old fantool xex's :X, thankfully it ended up working fine on a 256BB Jasper. I read about some people having their xbox spitout errors after patching and running it, but I got through fine.

After setting my speeds to 100%, I left my kit on at the H3B Main Menu where it flies around a real 3d valhalla for a little over two hours, here's a picture I took of the temperatures afterwards. Figured it would somewhat accurately demonstrate gameplay without me actually having to be present.



Just a side note, but I've noticed jaspers seem to be running a hotter MB temperature then other revisions, kinda funny.

Maybe later I'll go back to the 44speed and get a 'before' temperature picture. I'm curious as to how much cooler the jaspers run anyway. No other modifications have been made to the Kit.

-NHN!
