G5 conquest 2.5 quad G5 LCS leaking

[Macdrone]

Ok got a powermac G5, unknown to me its an LCS 2.5 that wont boot.  It has leaked onto the cpus, i cleaned them and am letting them it until i clean, replace o rings, and refill.   

Should I even try or are once the cpus leaked on are they garbage?

Man! I didn't know that could happen to Quad G5s! Mine's still looking good ATM but since I keep postponing the inevitable LCS overhaul, that could also happen to me... First order of business next week then is to take it apart again.

Could you show us some pics of the damage? Since the Quads had Dex-cool instead of the usual green coolant, I can't tell you for sure if it's repairable... I know some guys managed to remove the green goo off of their 2.7 G5s and made it work again.

i looked online and the single pump is green coolant.  the damage to one of the cpus rotted a whole side off.  pretty sure its toast.  the main cpu didnt have corrosion it was just gooey.  i cleaned it.  the other one everything the coolant touched fell off the cpu.

Sorry no pictures as i just dove into it blind as usual.

Well the processors fell apart when dried so the whole setup was toast, but for 28 dollars on ebay i ordered a working replacement supposedly.  We shall see.  Ill still rebuild this cooling setup just in case.  Not to find an AHT disc, I think I have one somewhere for the G5.

Can you provide pics?

the processor fell apart from the corrosion.  Nothing worth taking a picture of.  Looks just like a maxell battery explosion but green.  The O rings looked intact but green and white covered the lower processor around the heat sink and it ate every pad.  Nothing to save procesor wise.  It didnt leak on the motherboard or the power supply, so it was a slow leak.  Ive cleaned the heat plates already, just need O rings and new coolant.

That's one reason I only have air cooled G5 towers.

I picked this up for nothing thinking it was air-cooled, so far even then every G5 I have had has needed a new motherboard due to ram slots or new processors, so far a full life on needing processors isnt that off the mark to the air cooled units.

I have 4 G5 towers. An original 1.6ghz PCI single, a dual 2.0ghz PCIX, and 2 PCIE 2ghz DC. All are air cooled and none needed a CPU or motherboard to work (so far anyway).

 

[Macdrone]

your lucky, yet to see any G5 without an issue.

From what I have read the G5 towers had tons of motherboard issues from the start. I just assumed the bad ones died and the half way decent manufactured ones lived on. I also get the impression the G5 towers were ditched for Intel ones and didn't get as many years of use as say the G4 towers did because of the switch to x86 Intel.

My dealings with G5 iMacs were the opposite of the towers, every one I got was dead for some reason or another (mostly capacitors or power supplies).

G5 towers are going to end up like P4 towers, nobody wanted them when they became slow/obsolete and most will end up recycled.

I've got a G5 and three NetBurst towers (all Dells) so that era of machines is alive and well here...

Ive fixed quite a few aircooled with replacement processors and baking the motherboards, but all i have ever seen had issues that needed repair before they worked well.

LCS seems just to make things worse.
