Just because a tradeoff is difficult to evaluate doesn't mean you shouldn't try to do it. ;-) If the heatsink did not impede flow to the sensor, then anything you attached thermally to it that responds faster than the sensor itself should speed things up because heat will flow from the faster bits to/from the slower bits. Assuming a large amount of air flow etc. Best regards, Spehro Pefhany -- "it's the network..."
