what is the tdp or watt usage of the CPU's?
I haven't seen any holes in our pcb for the heatsink... Maybe completely different board.
Quoting the temperatures tests for same chip different device
"
0 min: Temperatures started to climb rapidly from starting temperatures of 50 C (zone 0) and 44C (zone 1). The CPUs were operating nominally at 1.99 GHz (A72).
+3 min: The zone 0 temperature started to hit a threshold of 70 C, at which point the A72 processors started to slow, initially alternating between 1.99 and 1.80 GHz. Handbrake performance is impacted by about -6%.
+15 min: Zone 0 now ~73 C range, with processor speed continuing to step down, looking fairly stable at 1.42 GHz. Zone 1 temperature continued to climb, eventually stabilizing at around 67 C. Performance impact is about -20%.
+20 min and beyond: Zone 0 temperatures fluctuating between 72 and 74 C, A72 processors operating mostly at 1.42 GHz, and occasionally dipping to 1.2 GHz. Zone 1 temperature is remain stable at around 67-68 C. Performance hit remains about -20%.

So it runs hot like our chip...
