The stock radiator is sort of small and after around 80 CFM you won't get a lot of improvment in performance. Same thig applies to going with a better radiator, a BI pro for example, your gains will only go so far before you hit a wall and going to a larger radiator (or more radiators) will be your only option.
B-H, you said a lot there and so did sbinh about the 100CFM fan.
No, the N500 isn't limited by the CFM on the air side once the speaker grill is removed and flow is improved. The N500 is cold-plate limited by the base thickness I had mentioned just a few postings prior.
The N500 will get more of a kick in performance, even when the CPU is under load, if taken 0.5mm~0.8mm off of the cold-plate base. This in turn will amplify the micro-channel sufraces for heat transfer.
To remove the material, one would need to fixture the cold-block level to the grinding table. Next index the grinding wheel operation to remove 0.02mm at one given time across the entire base before making the next index to step down another 0.2mm.
Once the desired removal is achived, polish the base until it almost becomes a mirrored finish. A dull finish will perform better than a mirrored finish using thermal paste. If the base is level, no scratches deeper than 20~30 micron, the cold-block will perform greatly.
