Help needed with cooling @ diy CXB3590 DB + HLG480H-C2100B

Hi guys,

Just bought 6 x CXB3590 DB bin 32V + Meanwell HLG480H-C2100B and need to design a cooling system.

I was thinking about going active using Arctic Alpine 12 (ACALP00027A) , but someone told me that Arctic Alpine 64 Pro Rev.2 (UCACO-A64D2-GBA01) is a better ida, (pricier but I suppose it's more effective..)

Or should I go passive?

ANY advice would be great!

Go passive. https://www.rapidled.com/160mm-pin-heatsink/
You will need alittle thermal paste to go under the cob and a holder. They should have all that there too
