DIY QB96 driver advice and options

More than 200w without active cooling? I was just thinking of passive cooling. I think they topped out around 325w. I might be able to push 250 with no added fans etc

HLG says the qb96 engine's with the sstx heatsink are good as-is up to around 230w, anything over 250w would likely definitely need a fan or some way to cool it.

Both of you and everybody else should read this thread, or at least it's newest pages: https://www.rollitup.org/t/diy-with-quantum-boards.927159/page-736#post-15254391, there's quite a bit on qb96s.

Update is that I've made a bunch of 2xQB96's running on single HLG-185H-54a's, I run them at 200 wall watts similar to @daveybc in the above thread, he's right temps and life are better that way.
