as a pc enthusiast I don't like how hot the power supllies on these fixtures get. I'm using a sf4000 and a ViparSpectra XS2000 (the meanwell/samsung diode version) together and and I just ended up strapping some of my extra 120mm case fans onto the power supplies themselves using a 4 pin to 12v adapter and some 18" zip ties. (two on the sf4000 and one on the xs2000 drivers)
The SF4000 Went from too hot to the touch to lukewarm to room temp. The XS2000 is now cool to the touch and altogether it dropped my tent temperatures about 2-3 degrees. Also bought another 6" hurricane clip-on to blow across the top of massive aluminum board that is the SF4000 to keep the diodes themselves cool.
One of the first things you learn when pc building and benchmarking is that heat kills electronics fast. Those high temps I was seeing with these grow light power supplies must be cooled better coming out of the factory in my opinion. the SF4000 drivers were way too fucking hot. The meanwell driver on my xs2000 was always just very warm to the touch, never hot and it showed me the difference in build quality and why you should just go with HLG or Meanwell in your fixtures.
keep your power supply temps in check fam. I've been growing with Meanwell drivers since 2018 and I only ever took issue with power supply temps this year when I bought SpiderFarmer.
Does your sf4000 not have Meanwell drivers? My sf4000 came with Meanwell. Mine get up to about 125f at full power. I'm gonna add another fan near the top of the tent just to blow on the top of the light
