Honestly, man, I just don't see any reason to use a heatsink with 120s. I'm running my four at max and you could sit a baby's ass down on those boards with no worries. Saying they get "warm" would be a slight overstatement, to be honest.
Edit: That said, my canopy fan probably does bring temps down a little, now that I think about it. Still, I can't see needing a sink, bro!

The drivers always get warm, I remote mounted mine on standoffs to keep them cool. Not having the warm driver in the grow space helps to maintain temps better.

I have a HLG-240H-C2100 that makes a buzzing sound when left hot for a while (I even have it dimmed). Does that happen to yours as well?

No, mine are all pretty quite, just minor 60 cycle hum in the background, very faint. I'd call who ever you bought it from, may have a bad one, if so however, first one I've heard of!

sorry for the but in question but does anyone know of a Canadian supplier for quantum boards or kits, all I've been able to find is American suppliers with high shipping rates and exchange rate

The exchange rate is what it is. I order seeds from Canada in US $ and get no benefit. Ordering seeds from Europe for US is very cheap right now.

ordering seeds and large quantum board and power supplies are 2 different ball games for shipping couple grams at most compared to lbs of electronics, there must be Canadian suppliers for these things

My hbgs hum a bit when at full blast but there caseless drivers none of my sealed meanwells buzz that i can hear. Rectifing ac to dc does create alot of whats considered electronic noise, they all should hum or buzz just slightly even too low to hear. How loud of a buzz are we talking and does it change when you dim

I keep it dimmed to a wall draw of about 175w-200w (goes up to about 250w), and the "loud" buzzing seems only to appear when the driver gets hot for a while such as when the canopy fan is kept off foo too long. I was amazed because I heard it while standing next to the room door, the same kind of buzzing some street transformers make.
