Taking note of how dirty the old ones are, maybe you can devise a cleaning schedule to keep them quiet and efficient longer.
The sad thing is, the lights are less than a year old! The internals and fans were very clean, almost like new, I keep it pretty darn clean in there. I'm fairly certain that one of the fans had just spun out its bearings, it was making a horrible sound like a car crash lol.

Of course they were the absolute cheapest Chinese fans ever possible in there lol. Anyway the difference in noise level is dramatic with the CoolerMasters! They're very close to silent now yay :)
 
I had an LED with a really loud fan, I took it apart and found out one of the blades had broken off so it was spinning out of balance. Same deal I replaced it and it ran cooler and quieter. That seems to be a common thing that the fans used are just junk so a few dollar upgrade can fix a lot of issues.
 
Should I bother doing a write-up/guide? Or you guys think people could figure this out for themselves lol? The fan wiring will need to be modified of course, but people could probably handle modding two wires themselves idk lol.

Beat you to it, see my sig :P

P.S. I reversed the flow direction so mine suck cool air in from the sides and blow it out the top. Which way are yours fitted in the factory bro?

I need to be where you are. I must live in the dustiest area in the nation. Not dirt, dust. There must be a felt factory or paper mill up wind somewhere. I'm running 5 coolmasters total in my cab when its cool weather. 4 pack like yours only larger and an even larger one for added exhaust. I can hear when one gets a buildup because otherwise they whisper and I can hardly hear them at all. Very inexpensive for the quality. I knew your grow would be Nasa lab clean.

Hahaa thanks, it stays fairly dust free in the tent surprisingly since it's in an outdoor barn. But I did do the old trick of hooking up a 4" duct booster fan for intake with a couple layers of womens pantyhose/stocking over the end intake. Really the only problem around here is about 1.5 months of really bad tree pollen which coats everything, but otherwise the forest magically keeps everything pretty clean! I would be extra frustrated growing in the dust bowl section of the country lol.

Good work on the Vipars Bilbo! From the factory, my fans blow down, from the top/in and down over the heatsink and then out the sides. I considered reversing them on upgrade, but after careful consideration I figured the factory must have known best lol. Plus it somehow made more sense to me to have the fans blowing directly onto the heatsink, although it also makes sense to suck the heat out versus blowing it out... So.. Maybe if I had a laser temp reader, I'd do a test both ways since I have two of the exact same lights.

Anth, Bilbo, I just read something on that, can't remember who wrote it, maybe pop22, or texasoldman, they play with Peltier coolers. It told about a burble formed by direct forced air being more efficient than drawing air across the heat sink. My coleman self cooler has a fan on both sides and both blow directly into the sinks. it creates cool rather than just move heat.

In other news, you guys starting to prepare for some outdoor season growing? I'll be putting a few autos out in the forest again this year, hopefully with some more experience I'll have better survival rates haha.

Instead of OG, I can call it FG, Forest Grown haha. Forest Grown Organics actually. FGO, sounds like a boring mortgage company lol. Anyway it'll maybe give me a chance to get through some of this bean collection too haha! I do have tons of those freebie photoperiod beans that end up piling up, but I'm still not sure I can manage some monster outdoor photoperiods at this juncture. So they sit in the box for now lol. But damnnnn, that Barney's Farm Tangerine Dream bean is screaming my name..... But I want to be sure I can do her right.
