Welp, got a lot more done today...
First, I already had been working on the power supply water block. Got it finished as far as the unit being sealed. The oven trick worked, but soldering those tubes on was a pain. Every time I tried to solder them to the main block they would "pop" off. Even with them submerged in water I had other problems. But, I perserveered and it is water tight.
I then began to dig into the power supply and pull the old heat sinks out.
As you can see there is quite a bit of space in there to work.
It's almost as if this power supply was laid out for water cooling.
Here, I have the board pulled and you can get a better look at those heat sinks.
There were two screws in each of the heat sinks that mounted them to the circuit board. I've removed two of them and the third is loosened, Red circles. The pins for the various regulators are outlined in Blue.
Here's the first row desoldered and removed with it's heat sink. I've written the part numbers down and mapped their location so I won't forget where they go.
Here's the second one...
I've put the regulators back in their spots just so I don't loose them. All but one have insulating heat transfer pads (rubber like substance) and insulating washers for the screws. When I put this back together I will have to put a meter on the block and make sure it's not providing a small voltage.
Here are the two naked heat sinks on which I based my "fingers" for the water block.
The first "finger" is done...
Both "fingers" along side the original heat sinks... pretty close
This is what I hope the solution will look like when installed. Just mocking it up here to get an idea of whether I've gotten everything to fit or not. Looks like I got it pretty close.
Also measured and marked the holes for the regulator mounting screws. I will drill and tap those tomorrow as well as drill and tap the mounting holes for the "fingers" to the main block. More then...
