Iv got some bestva 600w LED lights and the fan noise is louder than my exhaust and in tent fan. Are there any out there that are silent or can I just remove the fans of the LEDs?
No, the fans are most definitely there for a reason. You'll have to invest in better quality lights. You get what you pay for with LEDs and those fans keep them from overheating.
Replace the fans with quality low db fans. Search for silent computer fans of the same size as what's in your light. Likely 80mm or 120mm
Yeah, the fans that many companies put in their lights are cheap POS fans. Since computer fans work pretty hard over their life and are usually expected to run quiet and for years they are the perfect replacement. That said, you can certainly get lights with no fans. I'm not sure if you knew that. That's one of the big new things in custom led lighting. Passive cooling with no fans. The last 3 light fixtures I've ordered have no fans. I'll tell you what though if you run them at full boar you'll end up adding a clip fan in the top of the tent anyway because even though they're passive and efficient when you make that much light you make a lot of heat. No way around that. Look Ma, no fans! =) 600 Watt Vero29 V7 4x4 Framework Horticulture Lighting Group 260 Watt Quantum Board LED Kit
