Excessive fan
Hello
im hoping someone out there can shed any light.
I have an early Mac Pro 3.1 8 core, 3.2Ghz machine.
Pretty stable machine despite age. I updated to the latest 10.10.4 Yosemite software. Since then 4GB of RAM disappeared only leaving me with 8GB in total and every time I try and render from my 3D scene (Cinema 4d) the fan gets scarily loud I'm worried it's going to cook my Mac. Didn't have that behind prior the update and now worried to render off my sequence in case the fans die. I have tried re-seating the RAM and switching the sticks round with to
and bottom riser but no luck. One thing that is apprarent is the RAM sticks get incredibly hot very quickly after short use whereas this was not the case prior.
Any ideas would be welcomed. Not sure this update is right my my older Mac.
on a separate note. My mac keeps making intermittent chiriping sounds. has been doing so for a couple of years. Definitely not the hard drive as I changed it over a year ago and sound hasn't stopped. the sound appears to be coming from the front of the Mac. The heat sink cover keeps popping open and have taped it down with insulation tape but the heat keeps pulling the tape open. I am aware this chirping sound is a problem with the older Mac Pros.
Look forward to any replies.
Best
