It was like this before, it's a normal behavior, so I'm only concerned about CPU A. When Idle, CPU A diode Temp is about 48вЊ (with default fan management). When spinning faster than usual, I clean the accessible ones, and used air spray to remove what I could from the heatsinks without removing them. The only thing I was used to check was the Fan RPM. I never had any shutdown or strange behavior with it so it was 'normal'.

(2009 Mac Pro in storage for years now.) IIRC, 3rd party kernel extensions for reading internal CPU (Core) temperatures are no longer allowed in later OS X versions, but maybe developers have other ways now.) Back in 2010 when testing (X5550) 2009 Mac Pro CPU temperatures (before audio/FW IO bug fixed), there was some confusion over readings/accuracy, max temps of cores/how they were determined, etc.) Temperature Monitor/Hardware monitor back then was the best/most complete/accurate utility, but I've not used any since. ( Did you flash your (2009) Mac Pro 4,1 bootrom to (2010) 5,1? (He later said yes.) The Mac Pro 5,1 rom has microcode changes for Xeon 56xx series CPUs, (as well as enabling faster memory and audio via Mini Displayport). But with Mac Fan Controls, those names are referring to the Heatsinks temp sensors (yeah, I discovered some new sensors last week installing mac fan control ^^) CPU A Diode is going way hotter than the Heatsink! And I never checked that before. I've always used iStat widget (not menu and never used MacFanControl before), and the only temp sensor I've read for the past 7 years since I bought the Mac Pro was called 'CPU A' and 'CPU B'. CPU's working blazingly fast! But they go really hot too without fan triggering! I read some articles about fan management and OS X since Mavericks, I wish I read them before. I made some stress render with some Blender benchmark scenes. Ref: Mac Pro Northbridge High Temperatures due to Broken Heatsink Retainer.) ( While you have the CPU tray out, check if the Northbridge heatsink (plastic) retainers are still intact.

(By the way, heatsink fans were full of compact dust! I do clean the 'accessible' fans every 6 months, but never feel the skills to remove the heatsinks since last week) I did not want to detach the mac pro heatsinks, so I carefully screwed them down, tried to boot, checked the RAM, the temp sensors and the fans.

( Integrated Heat Spreader) I read some articles and checked some videos on Youtube where people mentioned that CPU with IHS could be installed but the Heatsink mustn't be screwed ( over?) 80%.

The CPUs I ordered on ebay from Germany (I'm living in Belgium) where sold with IHS. This MacPro has been used on many of my productions for 7 years, night and days of rendering more and more heavy 3D scenes.

They're still working, but as I'm a 3D graphist and animator, I wanted to upgrade them for faster rendering.

Last week, I ordered two 3.46Ghz x5690 to replace my two 2.93Ghz (original CTO from April 2009). ( at Mac mods/upgrades page, other 2009 Mac Pro 12-core upgrade reports) Hi! I found a lot of answers on your website. ( He later said EFI updated to Mac Pro 5,1 to support these CPUs, faster RAM) MacPro 4,1 - CPU upgrade report and question.
