Okay. So,I've got a 39003 v7 along with a Dualshock 2 for 50 bucks. Now,I hooked it up,and it works fine,but the fan starts to get very hot while I'm playing any game. Any ideas if installing a old v10 fan I have will work better than the v7 fan?And will it still keep the PS2 cool? Additional info that may help is the laser inside is a KHS-400R,and it has the smaller cube-shaped heatsink,unlike the v9 I have which has normal heatsinks (like on PCs)
What makes you think that replacing the fan will make it heat less ? lol The 50k heats less than the 39k because it use newer chips which draw less power therefore it heats less. You have to see how hot the original launch day consoles (SCPH-10000, Japan only) run. The "fat" PS2 consoles used mostly the same fan for the whole life of the console. Only time they changed the fan was when they started making the 37000 series, around 2002. So your 39003 will be using the same kind of fan a 50003 uses. If for whatever reason your PS2 overheat it will power off by it's own then will start to blink the red light. Stop worrying about things you don't need to worry about. I would be more worried about it having that crappy SANYO (SF-HD7) laser. Edit: Just to be clear about it, KHS-400R doesn't exist, that's an SF-HD7 (SANYO) laser with die cast metal body... Later they started to make them with plastic resin body.
So...the laser I have is a open-faced HD7? This is how the laser was looking like when I first opened the PS2: View attachment 9988 I played a few old PS2 games I found in my disc mountains (I have a lot of discs for PC) and they all worked fine without FMV skipping. The only HD7 I've seen until now was the closed-face HD7 found in 2 50003 consoles.(silver v9 and normal black v10) I have 2 spare lasers though,a KHS-400c from a v7 39004 and a KHS-400b from a scrapped v4.
What makes that laser be troublesome is the coils on it being heavier than the ones on the SONY pickup. The information of which kind of pickup is installed on the console is stored on the EEPROM. SONY had a couple of programs for Windows which were used to setup the EEPROM stuff (including laser pickup type) and to adjust the laser pickup after installed (stuff like laser power, focus and tracking micro adjusts)... So the procedure to replace a laser at a official service center would be roughly like this: Hook the console with the special serial cable to the service center PC Replace the pickup with the new pickup and put all adjustments at the "center position" Set the EEPROM back to the default settings using the first service program (reset the EEPROM) Using the second program they place CD and DVD test discs (Sony recommended YEDS18 and that special glass DVD disc that costs a grand) and run mechanical adustment for the white gear (mechanism tilt) and laser pickup black screw (mechanism parallax) so the program reports best adjustment. After that they run the third program and use PS2 specific test discs to do the fine adjustments. Then they return to the second program and use it to check if adjustments are satisfactory. If the laser put in it was really new, these adjustments are good enough to make the console as good as it was when it came out from the factory. P.S.: these tools leaked in 2002 or 2003 through PS2 Owns so they're on the internet. They work on all PS2s up to SCPH-3900x
