The rig is very quiet during test runs, practically inaudible amidst the ambient noise of an average urban home.

always nice to see the idle vcore at 0 volts, thanks to Intel power states and a proper PSU

i noticed idle vcore reading goes to 0 volts specifically when "package c state limit" is set to enabled (default auto)
sometimes cpu cores still at 3700 not yet at 800mhz, but vcore reading already at 0 volts :s22:
do u think 0 volts reading is actual vcore volts, or tat the package sensor goes to "sleep"...? :o

A few factors are at work here


  • hwinfo64 sensor polling interval is set at 2000ms default
  • Platform Timer Resolution for C states is OS/app dependent & very much finer eg. Win 7 is 15.6ms

Simply said, hwinfo64 polls the sensor too infrequently to give a true real-time reading.

thanks for the refs :)
iirc, when i changed to windows high perf mode for constant 3700, the vcore reading still dropped to 0v at idle
i guess likely vcore related to cpu load not cpu freq...
but hard to imagine tat vcore is really 0v, tats why i thot maybe its just the package sensor goes to "sleep"... :o:s11:

Actually, the Intel C6 Power state has been around for a long time already and was introduced 8+ years ago 1st on Intel's mobile CPU line. Here's an old article on it.

http://www.anandtech.com/show/2493/18

With mobile Penryn Intel introduced a new power state it calls C6. In the C6 power state the CPU is in a virtual reset state, and core voltage is very close to zero. The core clock, all of the PLLs, and caches are completely turned off.

AIDA64 Stability Test
just a short run for some idea of CPU load temps, plateauing out at max 66C in this test.

Daily Usage
surfing, downloading, unzipping, internet radio, UEFA Euro 2016 etc... the CPU idles in the low 30s and maxes in the mid 50s while max fan speed is just below 1700rpm.

Initial Impressions
For avid PC gamers who love a small rig, yet desire being unconstrained by a compact case in wanting a fast gaming tualengkong video card, this is definitely a good choice.


  • elegant sleek stealthy looks, beautiful full aluminium facade
  • solid construction which aids in silent running
  • compact yet well laid out design
  • great ventilation for both CPU and GPU
  • caters for the longest gaming video cards


May be improved

  • not tool free
  • 1-2 screws with access difficulty
  • PSU exhaust path
