DRAVEN Posted February 12, 2011 Share Posted February 12, 2011 Just abit of info for guys to keep a eye on... 90% of ylod is caused by over heating... the reason for this... sony set the stock speed of the fan to 20%to cut down on noise.. same reason for xbox doing it.. So the rapid heating and cooling is what cause's the solder joins to go or when the temp sensor starts to fail the fan dont kick up to cool the system Their is a mod you can do to set fan speed to 50% or 100% speed 100% will be too loud for some lol diagram for 50% speed mod.. http://forums.xbox-scene.com/index.php?showtopic=727112 Link to comment Share on other sites More sharing options...
caled Posted February 13, 2011 Share Posted February 13, 2011 This is interesting, given that I need to fix my PS3 for the 3rd time now. Does this mean the fan is spinning at, say, 50% constantly? Even when it wants to get to 100%? Link to comment Share on other sites More sharing options...
DRAVEN Posted February 13, 2011 Author Share Posted February 13, 2011 yes your setting the fan to run at 50% speed all the time its been tested and theirs a post were a guy says all the ylods he has fixed and done this to have not come back to be repaired again but the one that have not had the fan mod do come back to be fixed again The reason for ppl opting for 50% speed is its not too loud lol search youtube for vids of the ps3 at 100% fan speed..

caled Posted February 13, 2011 Share Posted February 13, 2011 Yeah, Ive heard them at full pelt, theyre not quiet. My worry would be limiting the fan to 50% speed, as it may need to go higher than that during use. Link to comment Share on other sites More sharing options...
eetaylog Posted February 14, 2011 Share Posted February 14, 2011 As above, you will be setting your fan to run at a constant speed with this mod meaning that your ps3 wont be able to ramp up the speed should it need to. If you want to do a proper job of modding your fan speed, use a temperature sensor (such as a PT100) as a replacement for R1 in the schematic. This will then automatically change the resistance (and therefore the duty cycle of the 555) with changing temperature. Make sure you include an offset resistor in series with the PTxxx temperature sensor though so that the fan speed cant fall below a given speed.By the way, i dont think the 555 circuit in the link is correct. Theyre normally wired up like this... http://www.evo-host.co.uk/getimg/26326.jpg Link to comment Share on other sites More sharing options...
DRAVEN Posted February 14, 2011 Author Share Posted February 14, 2011 I'm gona look at a putting a switch in for sensored speed or 100% speed or if the noise dont bother me i'll set it to 100% all the time Link to comment Share on other sites More sharing options...
DRAVEN Posted February 16, 2011 Author Share Posted February 16, 2011 Just found this on ebay think i may get one http://cgi.ebay.co.uk/PS3-INTERNAL-COOLING...=item2309d3f4e9 Link to comment Share on other sites More sharing options...
eetaylog Posted February 17, 2011 Share Posted February 17, 2011 Replacing a DC fan supply with a PWM supply will reduce your fan speed, not increase it. Link to comment Share on other sites More sharing options...
DRAVEN Posted February 20, 2011 Author Share Posted February 20, 2011 I dont really care about fan noise so I wired the gray wire to a 3.3v supply Link to comment Share on other sites More sharing options...
