Just wondering whether anyone has tested the thermal performance of the non-TB MBP under load, and how long it takes before the CPU speed throttles? I think an Ars Technica review mentioned that both the 15W 2.0GHz and 28W 2.9GHz i5 CPUs were able to sit at their max turbo frequencies for 30 minutes, but that applying GPU load causes the 15W to throttle sooner. I would be pretty happy if it's possible to run the 2.0GHz i5 flat out at 3.1GHz turbo speeds for 30 minutes (e.g. Handbrake encoding, video rendering etc.), but I'd like to hear more opinions about whether this is actually possible in practice. Thanks, John.
