Coolrunner heating issues

[Kratos8051]

Goog day guys,

I have just sucessfully RGH my Falcon phat Xbox. Thanks goes out to TX for a superb product.

I want to find out something from you guys. It feels like my Xbox is overheating after the RGH. I have no idea what the GPU, CPU and memory temps were before the hack, but the fan speed is certainly much higher (in freestyle dash, my CPU temp is +- 50 degrees, GPU around 60 and memory almost 80) - which seem a bit high. Did someone else also detect this? Maybe the temps are normal, but Freestyle dash overwrites the fan speed controller?

Any help would be appreciated. Thanks!

hi i had this as well all i did was putt the fans set to 70 and it cools it right down mate

if this help please hit thanks

You really want to cool that falcon , remove the dvd drive and replace it with an extra fan. There are plenty of tutorials around about cooling mods for falcons. My suggestions remove the drive buy a CK3 PROhttp://www.team-xecuter.com/forums/showthread.php?t=64354 flash the drive to 0800 fw use it to rip games via your pc. Upgrade your hardrive to hold more backups.

Thanks for the help guys. Strange thing is, I played around with the fan speed settings and there is no change between auto and 100%. I'm thus assuming it is running full speed.

accat131, so you also agree this is not normal? The question I have it why this could be happening after the RGH. Is it possible for the glitch to cause overheating?

I think what I will do, is remove the heat sinks and install a TX RROD kit. Maybe replacing the heat compound will do the trick.

What did you use to build the RGH image?

Don't forget that you're disturbing the heatsinks when you remove the board, so if you're having issues, replace the thermal paste on them.

Hi MartinC

I used Coolshrimp's Jtag Tool to program the Coolrunner, but 360 Multi Builder to generate the ecc-file as well as the freeboot image. Is there a better tool? Could the methods used to generate the RGH files make a difference?

This is also what I thought.

One other thing to check, make sure that BOTH of your fans are running. When I applied the RGH to my Zephyr board, I found the fan connector to be dodgy and only one fan would run thereafter. I have Talismoon fans in there and I'm running them at the full 12V via the DVD drive power cable. I've also applied TX's awesome RROD kit, but used Arctic Silver 5 paste instead of the stuff from the TX kit. Works a treat, is slightly noisier, but it beats a dead 360 any day.

Thanks Chris. Will check that tonight. It was difficult installing the fan with the Coolrunner in place. I didn't really leave enough room for the fan.

What version did you use? I ask because there was a hard-setting of 70% fan speed in one of them. If you didn't replace the options.ini then it automatically puts the fans on high.

It will be funny is this is the case. I used 360_Multi_Builder_v0.4 (going to update to the newest dash tonight, so will be using 0.7). I think the JTAG Tool I used was 4.21.

Edit: I see that Multi Builder 0.3 had the speed control set to 70%. I'm not home, so I can't be 100% sure which version I used. However, I think it was 0.4. So it might not be the issue.

Kinda had the same issue and this is what I did about it:

150 on the gpu :eek2: i highly doubt that as the machine cut off is less than 100 and 150 under power would blow everything in there.

Fahrenheit, not Celsius lol

OK guys, here are my results. First thing I did, was to check the fan connector and that both fans are running (which they did). Then, I updated the kernal 14599 using the latest 360 Multi Builder. This changed nothing about the fan speed. I then proceeded to replace the heat paste and install the TX RROD kit. This worked like a charm! The temperatures were still the same, but the fan speeds were way lower.

Now, this led to a couple of questions. What are normal temperatures for the GPU, CPU and memory? My case temperatures seem fine. The second question, why did replacing the heat paste reduce fan speed, but not temperature? This would suggest that the fan speed is not directly related to the chip temperatures.

They are directly related.

Fans are only as efficient as the heatsinks which are dissipating the heat away from the die.

example 1:

Bad thermal paste = heatsinks are not efficiently dissipating the heat = fan speed must be high to keep the CPU cool.

exmaple 2:

Good thermal paste / heat conductivity = heatsinks are efficiently dissipating heat from the die = fans don't have to work as hard to remove the hot air.

 

[Kratos8051]

Hi MartinC,

Yes, that makes sence. But where is temperature measured? If I measure the same temperatures at the chips, wouldn't that suggest the fan speed stay the same? Or is the Xbox capable of detecting the heat dissapation of the heatsinks and if that is insufficient, it increases the fan speed?

 

[Martin C]

There are TCs inside the CPU/GPU and RAM chips. The ANA/HANA then changes the fan speed accordingly.

Your second statement doesn't make much sense.

Look at my examples and imagine a set of scales with one side being thermal dissipation and the other side being fan speed.

 

[Kratos8051]

Ok, I think I have it now. It would seem like these temperatures for the Xbox are normal operating temperatures. With insufficient heat dissipation, the fans have to work a lot harder to keep the console running at these temperatures. With proper heat dissipation, the heat sinks are doing a proper job and the fan speeds can be lower.

Thanks for your help!
