If the new machine has a factory-installed heatsink, then more airflow is likely to be much more effective at handling peak-power heat than trying to find a new heatsink that will fit.

5-10C difference from location in the case, sure.
30C, no way. The first CPU isn't more than 30C above ambient, so the air coming off that heatsink can't be 30C over ambient either!

Looks good to me- fits the trendline for C190 and C192 (never mind the outlier huge score posted for a previous C191, better than the C190 record).
