Current/Former liquid cooled G5 owners, question
Posted by: Pat

New to me 2004 dual 2.5 to replace my now dead 2003 2.0 (cracked solder).

Anyone remember their operating temps? How hot is too hot?
Currently with 78º ambient:
Idle - CPU A 135º, CPU B 120º
Normal use (PS, video, browser open, etc) CPU A 165º, CPU B 145)
Dropping the hammer and maxing out the processors CPU A 185º, CPU B 155º
These temps seem normal? Googling has come up with 8 billion different opinions of what is normal and what is too hot.

As a precaution, I dug into it and the LCS had never been opened up. I pulled the shrouds and checked for any signs of leaks, none found. Fins are clean. Thinking about pulling the LCS to put down some new thermal paste.

Seems pretty good. I wouldn't do anymore to it, just replace it when it dies.

Sounds about right. Paste redo should be biggest help for you. Had issues w/ power supplies on G5's, but the LCS models were power hungry beasts. Miss the DC 2.3GHz G5 more than the quads; it was quiet, and quite functional for what it was. The quads were noisier and hotter, and yes, faster, but never felt right. Newer Mini's turned out to be faster, only issue is connectivity. What I found works best for all cheesegraters is small fan pointed at front of cheesegrater for add'l flow thru ventilation; seems to be a big help for cooling the rig. Good luck.

Use GOOD heat sink compound if you can get it easily. Arctic Silver or one of their similar products. Higher quality and does better heat transfer.

Those are °F right? CPU temps are generally reported in °C. That is very high for °C.

Well, the G5 would have really earned its reputation if those temps were C.

The one here would frequently reach 160ºF but very infrequently did it actually get into the low 180ºFs. The rest seems 'normal'.

Installing a fan control control panel helped keep the temps down, but it made the sucker louder than it needed to be. Average temps then moved up slowly until eventually, the unit began leaking. There was probably a very slow leak for awhile since there was a tiny area of etching on the case - and there really wasn't all that much coolant to begin with.

Although the G5 was out of warranty for a few years (2009) when it died, Apple replaced the unit with a brand-new (early 2009) Quad-core Xeon. That one has been the main machine ever since, and it rarely, if ever, hits any temps above 140ºF.
