I did not say anything, because it was a professional place and they assemble server for a living. I noticed that the guy who installed them did not clean the heatsinks from thermal grease.
So under heavy load CPU A is 10˚C above this value. With its stock hard drive, the 2012 Mac Pro drew 257 watts at startup, 147W at idle, 220W at sustained load. I made some screenshots under different usages with temperature readings and CPU utilization. We measured the power draw of this 8-core 2013 Mac Pro versus a 12-core 2012 Mac Pro. Furthermore both heatsinks seam not to heat up properly.Ĭould someone please confirm my temperature readings? At the time of purchase, Apple originally offered the stock 'Quad Core' model - the Mac Pro 'Quad Core' 2.66 (2009/Nehalem)- with a single 2.93 GHz Quad Core Xeon W3540 processor as a US500 upgrade. So under max load, the faster CPUs will draw 2X35 70 watts more power. I have a higher difference in CPU temperature than Paul (around 10-15˚C when idle), but under heavy load CPU A gets up to 88˚C or 191˚F and CPU B 55-60˚C or 131-140˚F with a difference in temperature of about 30˚C. s Ultimate Mac Lookup feature - as well as the EveryMac app- also can identify these models by their Serial Numbers. The 3.33GHz W5680 is a 130 watt CPU, whereas Apple’s 2.93GHz 12-core uses 95 watts.
I recently upgraded my 2010 MAC PRO 2 x 2,4 QUAD with two X5690 XEON CPUs I have bought used on eBay.
