How to Repair a G5 Quad Dual Pump LCS

Recommended Posts

Thank you @BadGoldEagle

Anyway I saw the screws have a "limit” (you cannot tighten them in infinite) and that’s the reason why I asked. I’m thinking maybe they were not tighten enough.

 

About the o-rings... yeah but the pressure is between the copper and the little aluminum plate. Which is "unusual”? Strange anyway. But I’m thinking LOL if they were put there for assembly only.

Mhm... yeah... are you sure about it? And then, why putting them at all?

(I found they are useless too. I mean, I cannot see their functionality)

 

Another thing, when putting the screws with the springs (the one that attach the CPU PCB to that metal plate behind the copper liquid thing) should I tighten them until the screws stop? 

I didn't say they had no use, I said it helps assembly when attaching the waterblock to the CPU.

Yeah, sure... but I expected something more "important"...

I’m going to replace them anyway though.

Guys, another thing... what can I do for these?

 

Ps:

do you suggest me to change the thermal compound on the North Bridge too? How can I check its temperature?

@kby You wrote about testing the LCS connecting it directly to its wire. What about those holes in the CPUs PCBs? I mean they are always power related... I do not want to make something wrong. Thanks

Just sent the same post two times... apparently I cannot delete it...

 

Since I am here... would someone explain me “what I have done” in the picture above? It was not me, but the old owner. I do not like it though. I am worried since it is the CPU PCB itself.

Hello again... I wrote a long post until the page refreshed. I’m very frustrated now...
Anyway I made the disassembling.
What I have now is this:
• the liquid was like water, no color at all...
• there was little liquid inside
• no @BadGoldEagle orange little balls
• what kind of hoses they are? Seems very strong and made with two materials. The inside is something like plastic, and outside rubber.
• What kind of glue it is? I need the same glue.

That’s all... :)
