Would like to add a blue led to mine
I used 3 heatsinks on each power supply that were recommended earlier in this thread with self adheasive and designed to lay horizontally. They fit perfect, they go right on the super hot plates of the SMPS and they cool to such a level you can easily now lay your hand across the entire power supplies with no real heat left over. Very nice for about 8 bucks! The NC400 is fine, it barely warms up even under heavy load. And dare I say actually the performance seems better, I can crank with no frequency shifts and very consistent smooth sound. I have a case much taller than most here, actually my case is close to double the height most guys used so these heatsinks fit great, and they are air cooled via the vents on the top of my case with Zero issues now. They were running hotter than most amps, now they run much cooler than any other amps I had. Worth just putting a little effort in, I don't like the Cigar box style jam packed anyway, but thats just me. And I did have one SMPS go bad in the first week so they did replace it and if you plan on leaving these amps on 24/7 I suggest sufficient cooling. Of course I did run DUAL mono so they are in one case where others are using them in 2 smaller cases and likely do not get quite as hot.
I just wanted to underscore that I'm not really worried about the heat issue, at least in my implementation. I would worry about putting them in really tight chassis, with materials that don't allow heat to escape well, etc, but that's not my situation. Mine are good size, all aluminum, and vented on the top plate. I'm really just interested in getting a firm grip on what the power and heat parameters really are in the real world. Also I'd like to know if I should make any adjustments of my own to further optimize. Those CPU heatsinks could be really handy, but the SMPS doesn't seem to be the problem child for me that it is for others. Would it make sense for me to apply those heatsinks to the electrolytic caps on the modules? That's where it's hottest right now in my implementation, and where the highest heat seemed to be in the calibrated measurements several posts ago.Or maybe I don't have my modules coupled properly to the chassis after all? I mean, I think they're pretty firmly physically connected, but maybe there's a slight physical gap? Or maybe that silver thermal compound doesn't work as well as they say, and I actually created more of a barrier to thermal conductivity by using it?
sorry to bump this thread, i've had my ncores for short of 2 months now, the cases they are in are only 6mm taller then the psu heatsinks internally. i have them bonded to the top lid with thermal pads. my case is also sealed with NO vents. My cases are all aluminum, but do not have heatsink fins for dissipation. i wanted to see if anyone with the amps for a much longer time then me have experienced any issues yet. I figured since its only been 2 months, i mind as well check in with others, if there are problems then i still have time to rectify it.
No issue. Bruno says it's fine.
