Q: G5 LCS refurbish and refill info

I have finally refurbished my G5 2.7 LCS, I know there have been lots of discussions here about doing this but I thought, if there is any interest, I would add my 2 cents. Here is a pic of the finised refurb, if anyone needs advice etc on how to refurb your LCS post a question and I will do my best to answer.

    That's pretty.

    I like clean work.

     

    How does it cool?

    Thanks for the compliment japamac, it's working great, temps are 52 to 54 at idle, the fans are silent and are no longer 'ramping'. Using a 'T' bar made bleeding the block pretty easy and I am really happy with my 'new' G5. It was a fun project and not hard to do. New fluid, rings and tubing along with a little gasket sealant should ensure a few more years before I upgrade to a mac pro. Thanks to all who helped with advice and tips.

    Hey Buddy, I think I need your help.  I just picked up two 2.5 G5 Quad's the PCI-X with LCS's one already leaked and killed the Power Supply the other is working but with 1 dead CPU.  I wanna pull out the LCS from the dead Machine and Rebuild that LCS and Steal one of the Processors and bring one back to life with a rebuilt LCS so it so it won't die for a least a while.  I can download the instructions on how to do it but was hoping for a list of parts you purchased to make yours look bad ***.  I especially like the clear tubing can you use that all around?  Hope you can get me that info.  Thanks in advance.

    Good news about the Quads, there's quite a few around with some kind of water damage, It sounds as though you'll be a able to get one good mac form two half dead ones! My mac is running sweet since the refurb, give me a day or two to check what I used and I'll get back to you!

    OK, here goes.

     

    Tubing - One metre, size is ID (inner diameter) 3/8 - OD (outer diameter) 1/2.

    The tubing specs use both measurements which can be confusing but this is the best set-up I found.

    Lots of colours are available but using clear is a good idea as you can check for air bubbles when you bleed the block later.

     

    Clamps - Size, 1/2, I would replace all the clamps, the screw kind are easy to get on and tighten.

     

    Anti Kink Coil - One metre, size ID 1/2, this helps keep the tubing open and the coolant flowing well.

     

    Coolant - Feser One Cooling Fluid, any colour you like!

     

    Thermal Paste - Artic Cooling MX4, The best thermal paste to date.

     

    O-Rings - Brand is Viton, the size is 31.6mm x 2.4mm, these are a little bigger than the original rings and have a better fit and seal.(Note, my G5 is a Dual 2.7).

     

    Gasket Seal - This is optional, I used it to add an extra layer of leak protection around the new o-rings. I used Permatex Ultra Grey, but any gasket sealer will do.

     

    Filler plug - This is a great way to make filling and bleeding the block easy, the top screws off letting you fill the LCS and it also allows you to bleed the block easily.

    T-Bar - Adding a T-bar allows you attach the extra tubing for the filler plug to add fluid and bleed the system, air in the LCS is a major problem for cooling as well as pump damage.

     

    I think that's everything, I live in Stocholm and used a couple of sites in Europe to get the parts I needed, you will be able to get the parts in the States I assume, but let me know if you get stuck and I'll help you.

     

    When your ready to start let me know, and I can offer some help / tips make the refurb a little easier.

     

    Good hunting!

    Just a passing note, the G5 Quads are not PCI-X, but PCIe.

    BD you are correct.  So used to typing PCI-X when I write about my G5...  Old Habits Die Hard, just like old macs...
