[ Index ]

Picture of the element.>>

DATA :

Dimension : height, depth, width ( 90 deg. to clip ) : 9 x  5 x 6.5 (cm)

Weight : 245 grams (0.245 kg)

Material : Copper

Made for socket 7/370.

Cooling capabilities (verified) :

• Intel Celeron II 700
  CPU Peak temperature : 53 C @ 26.5 C MB/cabinett temperature.
  CPU settings : 1.35 Vcore, 3.4 Vio, 66 MHz FSB
• Intel Pentium I 233 MMX
  CPU Peak temperature : 55 C  @ cabinett temperature n/a, but below 30 C
  CPU Typical temperature : 32 C
  CPU Idle temperature : 29 C
  CPU settings : 2.8 Vcore, 3.5 Vio, 66 MHz FSB

Estimated time to create : 1 week

Measurment & Environment factors :

All temperature data are normalised to an ambient room temperature of 20 C.
Air humidity : Normal. Standard livingroom.
All measurments are done in a closed cabinet ( AOpen HQ-45 ), with sligtly improved and optimised natural ventilation.
PSU used in all measurments are the "Tranquilizer" PSU(4), i.e. no ventilation fans.

Verified Test results and details :

Tested in daily use on the P-233 CPU for months without any problems. This is the element that comes out of the Fanless cooling ribb experiment . [ more ]

Also tested on a Celeron II 700 just to verify that it works here as well, and to provide a measurment referense to the refined DD element. [ more (test results details, description, etc ].
