  • IPC5 case: Measures 210 x 197 x 65 mm in black anodised finned aluminium, with no fan.
  • IPC3 case: Measures 231 x 200 x 52 mm in silver anodised finned aluminium, offering a slimmer case with side mounting flanges and no fan.
  • Installation: All figures are with the computer lying flat in open, still air, where room temperature is the air immediately around the case. A closed cabinet warms trapped air, so leave clear space around the fins and ventilate the cabinet.

Heat the case can dissipate across room temperatures

Heat the case can dissipate across room temperatures
Each computer lies flat in still air with 5 W of heat from the rest of the board included. The dashed line is the most processor heat the case can dissipate before the processor reaches its 100 °C limit. The solid line is the processor's power, up to Intel's maximum turbo power: 64 W for the Core i5-1240P and 55 to 57 W for the 15 W processors. The IPC5 case can dissipate 71 W in a 15 °C room and 42 W in a 50 °C room. The IPC3 case can dissipate 67 W in a 15 °C room and 39 W in a 50 °C room. The Core i5-1240P has a 28 W base rating and a 20 W minimum assured rating. Each 15 W processor has a 12 W minimum assured rating.

Hottest case point by processor power and room temperature (15 W class)
Peak case temperatures across 25 to 45 °C rooms for the 15 W configurations of the IPC5 and IPC3. A continuous 55 W maximum turbo load reaches the 100 °C processor limit in 35 to 45 °C rooms on the IPC5, and in 30 to 45 °C rooms on the IPC3. The processor lowers its power consumption to the wattages shown to stay at 100 °C.

Hottest point on the lid and average case surface temperature in still air across 25, 35 and 45 °C rooms. At base power, the average case surface stays about 2 to 5 °C below the hottest spot on the lid.

Processor junction temperature against processor power

Processor junction temperature against processor power
Processor temperature in still air across 25, 35 and 45 °C rooms, up to Intel's maximum turbo power. In warmer rooms the processor reaches its 100 °C limit below that power, and lowers its power consumption to stay at 100 °C.

Ninety-minute response from idle to a maximum turbo burst and base load

Ninety-minute response from idle to a maximum turbo burst and base load
In a 35 °C room, each processor bursts from idle to maximum turbo before running at base load for 90 minutes. On the IPC5 at 64 W then 28 W, the Core i5-1240P reaches 70 °C during the burst and settles near 71 °C. On the IPC5 at 55 W then 15 W, the processor reaches 64 °C during the burst; this model run ends at 21.5 minutes, with the processor at 54 °C and still warming. On the IPC3 at 55 W then 15 W, the processor reaches 65 °C during the burst and settles near 58 °C.
