| Okay just
had to share because it was fun... The power supply was to cheap to
even
bother getting replaced so why not... And here are the results. |
 This is the switch that failed and yes I tested it and yes it does not work I left it mounted for cosmetic reason. |
 The fix quite easy desoldered the connection of the 2 wires at the switch. Then soldered and shrink wrapped the wires together. |
 Here you can see the running test in progress at about 30 minutes run time. Still happy at a dead on 12 volts. And with the capacitance the ps has I also tested while switching on and off the water pump which fluxes the power pretty well. The pump kicks on and off causing a surge and the ps still held steady at 12 volts. I need to get that pump fixed. ;) |
|
Here you can see around 30 minutes after the last test that the 4 pin 12 volt cpu supply pin's output at a steady 12 volts. Again even after using the pump test again on both 12 volt leads of this connector. |
 This time you can actually see the probes in the Grn and +12 Volt connector. And the test is still running at 12 volts as I am creating this page. |
 Finally a close up shot of the above same scene still testing the main +12 volt dc of the ATX mother board connector. To save time and space I did not bother to post up the pics of the tests of all power outputs on this power supply. But I am willing to bet this supply is going run for a while. ;) |
| Now I guess I should mention here
that although this fix did work well I soon found out why so much heat
was building up inside my pc case. As it turns out the fans in this power supply were forcing air into the case not outside the case. So I had to mod the power supply once again and turned the fans in the opposite direction that they had been in. Now the pc typically runs with ambient room temp of 70 degrees at around 105 degrees average system temp. It was running at around 130 degrees average system temp and because of this the pc would shutdown in overheat mode quite often. This last mod helped a little as you can see. But I also modded the case a bit. Using a huge 5 inch 12 volt power supply fan and a shroud from an old retired Gateway case I have succeeded in getting the core system temp down to an average of 80 - 98 degrees depending on ambient room temp. The next cooling test will soon be done where I install a water cooling system into the system. I am still shopping for just the right one and still wonder if I should create my own to try out. Using a cooling system much like a combustion engine design and see if I can super cool this puppy with water and maybe use a bit of Anti Freeze too. Stay tuned as this is a work in progress as soon as I have it tested and trialled I will put up a link to the info on the Trial and Error page. |
