Okay need some help. CPU cooling fans are running at strange different speeds. Powermac G5 early 2005, dual G5 (not dual core).


This is at idle:

CPU A 60 degree Intake 300rpm Exhaust 300rpm

CPU B 63 degrees Intake 1125rpm Exhaust 1100rpm


! I have not noticed this before. They usually remain identical. Tried resetting PRAM, NVRAM, and did a SMU reset. No change. Any ideas? Thanks,

My Dual G5 (April 2005) was loud as hell (Dual 2.0 ghz)

Which G5 do you have?

If it is the 2.5, you may have a problem with the liquid cooling.

Dual 2Ghz, not liquid cooled. Maybe I'm getting over paranoid, but I thought I had not ever seen the cpus fans so different. And at all times! Could just be the summer heat? Anyone?

EDIT: And I have noticed that CPU A is steady at 300rpm in/out without change, no matter the CPU load.

make sure everything is clean and dust free...

also, one CPU is above the other.. heat rises. one processor could contribute to the heat of the other.

Summer heat definetely gets to the machine.

I guess you don't need to worry about it for now.
