I have 4 of the V3 MONO, 1 ZA3, 3 TB10D and YES, all get slightly more than WARM when running at 48VDC but my solution may not be pretty but it is SIMPLE, and WORKS.
I ordered many ALUMINUM heat sinks of various sizes and on the 3 TB10D they are on the TOP of all 3 units with 3 FANS blowing on them. All I did is put some 'THERMAL PASTE' like I use on my CPUs on the TOP of those amps, then place the HEATSINKS on top of that paste and they do not move and even without the FANS now barely get WARM. On the 4 V3 amps, I put the thermal paste on the bottom of each with a HEATSINK the same width as the case, and about 1/2 inch high and NO FANS. These are also running at 48 VDC. So far that has worked well but should they begin to get 'warmer' I will increase the SIZE (height) of each of the bottom heat sinks plus I bought 8 very small 12 VDC fans and have 1 on each side of each V3 blowing 'cool air' into the case and still have the BOTTOM heatsinks.
The THERMAL PASTE does a great job transferring the case heat so I 'drive these amps' to a LEVEL that most people might think is LOUD.
Anyway, simple solution! I have watched more than a few YouTubes with even a few telling of them 'frying their V3' and I say, these are AMPLIFIERS that will get warm or hot at 48 VDC but some have shown where they DRILLED some heatsinks and I say, just putting the THERMAL PASTE on, you can 'pick up the V3s' and the BOTTOM HEATSINKS stay where I put them. I hope this solution works for others that are 'pushing their V3s, and the TB10Ds, and the others that I have.
At some point in time, I will temporarily 'disconnect my ANTHEM 5 channel amplifier' and plug in the 4 V3s and see how they do with my four BOSE 901 series 6, 'just for fun'.
My 3 TB10Ds have 3 sets of DIFFERENT SPEAKERS with high quality speaker cables with my WIMM PRO 'feeding AMAZON ULTRA music' at them and a POLK 10" Subwoofer and All of that is on my COMPUTER DESK for me to enjoy my MUSIC.
