Hi to one and all,
I purchased a Power Mac G5 Quad Core (late 2005) last month for my small business, as I was in need of some firepower to out-muscle my old computer. I do music production and things were starting to slow down when adding in plug-ins. Unfortunately I was ignorant, and trusted a failing auction company, spending £350 on this very large paperweight which showed up to my door full of dust and unable to startup.
To cut a long story short, I used canned air and curiosity to clean the whole thing out, and managed to get it started up for the first time.
However, it often shut back down on startup and when I checked the stats, CPU B Diodes 1 & 2 were running around 89/91* whilst CPU A Diodes were running around 33*, which are where I believe they should be.
----------------------------------------------------------------------------------------------------------------------------------
THE QUESTION!
Why does one CPU pair run so hot whilst the other runs so low? It seems as if either the workload is being routed solely to the CPU B pair, or that the Liquid Cooling System (LCS as we know it), is only cooling CPU A very well and not cooling CPU B very well at all.
This sounds like a thermal conduction problem, leading to either a malfunctioning LCS or even poorly applied/dissolved thermal paste. (I've heard the thermal paste used was highly toxic so any honest answers regarding changing this, please consider safety )
There is hard green stuff around the tube connections of the LCS and no sign of any leakage, this seems like glue but if anyone has any other proven suggestions? How do I check the LCS is pumping and working well? Or that it is full with liquid?
Thank you in advance for any time taken to read or help, I've trawled every forum out there and can't find a specific answer to this problem.
Cheers,
Tryp
