Yep, 80mm. Which I'm planning on replacing with 3 of these:

Which comes to another $20.89 with shipping. We'll see how quiet they are.
I've had the case open and poked around inside. The connectors don't look like the same ones used in PCs, so I'll probably be doing some wire work too. And there's a lot of stuff crowded around the fans so it'll be a challenging swap out.
Considering time & money it'd certainly be better to just get the quiet ones from the start. It really seems to depend on the supplier, but that can be hard to identify.

I have been in a couple datacenters and it sounds like a tornado inside.
Sellers (especially on ebay) with old stock have the louder fans which is what is in my lights purchased 3 months ago. It only had the blue and whites. I should have swapped the fans when I replaced 12 of the LEDs to make them broad spectrum. The fans can be replaced when they start to wear out.
My friends shipment from Evergrow last week came with the quiet fans and a dark mat grey paint on the case. The screws for the fans are no longer visible from the top of the case and the fans were whisper quiet.

Can I buy cyan LEDs and put them on the IT2080 fixtures and if so what watts and where?

EBay and wherever you want.
The leds sent by evergrow/reefbreeders are better though, as they have an ic chip in them to prevent an entire string dying if a led dies, since the are wired in series. Any other led won't, but they don't offer cyan yet.
I've added them to my lights with no issues.

I was thinking of low balling him but you guy are making me have second thoughts on used leds.
Full spectrum, what's it missing?

You may have to experiment some, or maybe somebody who has experience with this issue can help more. I'd consider removing the lenses off the end 2 or 3 rows on the ends near the braces. Maybe even get some 120 degree lenses from Reef Breeders or EverGrow. This is a fairly easy job and completely reversible if it doesn't solve the problem.
Also, if your tank is less that 24" deep, you might try raising and lowering the lights to see if that has any effect. I wish I could be more help, but it not an issue I have really had to deal with. I have a center brace, but my lights are in a canopy so I could spread them extra wide and then tip them up in the middle and they ended up shining under the brace just fine. But that 'tipped' look probably isn't good if the lights are in full view. :lmao:

This is just my personally opinion, but with only 42 leds, I reallt wouldn't want 6 of them to be UV. I only have 4 in my 99 led fixture. I have no way to test this theory, but my guess is your PAR may be lower than it should be with that many UV's. The corals use some (again, in my opinion) but I'd rather have 2 shades of blue, more than just cool white, maybe 1 more red (could go either way) and I wouldn't have the green but it probably doesn't hurt.
Have you tested the light for PAR? That would be step one. I'd want PAR of at least 200 at 18" unless you are using this in a shallow tank. My D120 is 225-250 at 22-24". Also, what brand of leds are they? Did the seller build it or is it made by a company? If it's a company, which one? Avoid TaoTronics. If you are just looking for an inexpensive light that works in your situation, this light could be just what you need and it's reasonably priced. But if you are looking for a really good, solid light, I'd get a new D120 for the extra $80... personally, over a display tank, I'd go for the IT2040. My D120's are in a spare bedroom, that is now my reef room, hanging over a 55g QT and a 24g FT.

Hey Ron, I was curious about what you said about staying away from tao tronics, are they really bad to use.I just bought a 120 watt dimmable for my 28 jbj to try and see if I would get any growth from my corals.For my 75 reef I am saveing up for a rb it2080.

You would have to raise the light higher to widen the spread, or try removing the optics

When I first started looking into leds for my tanks, I shopped some on Ebay and Amazon. Amazon has buyer feedback and TaoTronics had as many bad feedback comments as good ones, that's a bad sign. It was stuff like loud fans and lights not working, and wort of all, no communications to direct customer complaints (something EverGrow has been super with). Now to be fair, that was 3-4 months ago and they may have improved since then, hey, even EG has improved their products in that same time frame. But EG has been good at customer service for as long as I've been paying attention (like I said, 2-3 months).
BTW, I don't pay close attention to coral growth as most of my colonies are pretty big. But over the past 6 weeks that I have had 2 of the EG/RB IT2080's over my 180g DT all my colonies have continued to show growth (the different colored edges and white tips), just as they did under 1050w of MH. And 2 small frags of branching sps corals have been hung by monofilament about 3-4" below the water surface and they have been growing like crazy in just 6 weeks (doubled in size). I only wish I had documented it in pictures.

I think of Christmas lights. With a bad bulb, the circuit is broken in a series connection, and they all go out. Maybe its different with LEDs.

Thanks Ron,the fans are loud on my unit.I will most likely get a 16'' dimmable from RB after the IT2080. I appreciate the input
yeah, just use a hanging kit with or without the included hanging kit and hang from your ceiling.
or if you're especially crude and really aren't handy, just grab a plant hanger hook and take some chain link from HD and hang that way.
