Ivy Bridge is HOT!



3DMark11 CPU Temperatures




 NOTE:  Prime95/Linpack/IntelBurn Test etc. will generally run these CPUs much hotter.

Not only does the older sandy bridge 2600k overclock ~14% higher than the soon to come out ivy bridge 3770k, the 3707k runs at a voltage ~13.3% less than sandy, and more disturbingly runs at a temperature ~21% higher (on the hottest core). Even a 12 threaded 3960x @ 5.06 Ghz with a whopping 1.57V runs ~25.6% Cooler than the 3770k. 

Is it just me or is 98C on the CPU a bit hot for a 3dmark11 run? My AMD FX 8150 @ 4.8 Ghz  (1.42V) doesnt hit above 65C on the same test. It is still nice to see lower idle temps despite all this. We will see if retail stepping fixes this embarrassing issue.
