K404 Posted July 20, 2015 Share Posted July 20, 2015 I have a couple of XBox 360s here to repair for friends. One is back up and running and OOOOFT these things are hot, coupled with poor airflow. Does anyone know how much I can drop the voltage before instability would become a problem? I don't want to spend hours testing these, if I could take e.g... 0.2v off and "be done with it" .... that'd be nice! Cheers Quote Link to comment Share on other sites More sharing options...
ObscureParadox_3XS Posted July 21, 2015 Share Posted July 21, 2015 Truth be told dude you are better off getting the later model heatsinks, they were better at cooling the system down and with good thermal paste + the later model heatsinks they weren't that hot. I might have a few here, PM me on skype if you want me to send you them? From what I can remember also it wasn't really a temp related issue that the 360 had. More than anything it was poor solder joints on the GPU that cracked and stopped the system from working, so reducing voltage might not really be needed. At the end of the day most laptops run 80c+ daily without much issue. Quote Link to comment Share on other sites More sharing options...
K404 Posted July 21, 2015 Author Share Posted July 21, 2015 Well... package and thermal are definitely linked. I'm pretty sure the one I had running yesterday would pass 80c effortlessly under load with the shell back on Please can you post pics of what you have? I just had a quick Google hunt.... these units might have the bigger heatsinks (and thankyou for the offer!) Quote Link to comment Share on other sites More sharing options...
Guest TheMadDutchDude Posted July 21, 2015 Share Posted July 21, 2015 80c is crazy. Have you got the heatsinks there with the heat pipe and one extra, smaller heatsink in front of the CPU? My 360 is a 2009 'Jasper' model and it still works flawlessly to this day. Quote Link to comment Share on other sites More sharing options...
K404 Posted July 21, 2015 Author Share Posted July 21, 2015 Here's what i'm working with: http://pcper.com/images/reviews/940/01.jpg It's the single-piece heatsink that's getting hotter. Heatsinks have been cleaned and lapped. Arctic Ceramique paste. Quote Link to comment Share on other sites More sharing options...
ObscureParadox_3XS Posted July 21, 2015 Share Posted July 21, 2015 right so you have the latest GPU heatsink. I'll have a look for a CPU one here then Quote Link to comment Share on other sites More sharing options...
Guest TheMadDutchDude Posted July 21, 2015 Share Posted July 21, 2015 Isn't that the latest combo? That's what the innards of my Jasper model looks like. Quote Link to comment Share on other sites More sharing options...
ObscureParadox_3XS Posted July 21, 2015 Share Posted July 21, 2015 No they had a CPU cooler with a copper base and heatpipe too. Quote Link to comment Share on other sites More sharing options...
Guest TheMadDutchDude Posted July 22, 2015 Share Posted July 22, 2015 Whaaaat? I did not know this! Quote Link to comment Share on other sites More sharing options...
Guest k.pisti Posted July 30, 2015 Share Posted July 30, 2015 Even if better cooling would make it unneccessary, undervolting a 360 would still be maaad and super fancy! Quote Link to comment Share on other sites More sharing options...
