Do these get hot, and do I need to have airflow in the mounting surface?

No these lights put out very little heat at 12v, they are cool to the touch

These are LED lights and do not produce much heat at the lens (e.g. cool to the touch). Regarding the housing, I would ensure some minimum air circulation to dissipate heat vs. tightly enclosed, but there is very little heat output.

They do not get hot. But they do require a transformer which may get hot. I am using them in a kitchen exhaust hood which already had a transformer built in.

A bit late, but typically you would want SP (Static Pressure) fans on a rad... to deal with the resistance. Would squeak out a little bit more cooling performance from the loop.

Oh, and do a push pull configuration with that hearsink and youll never have issues. I also recommend arctic silver thermal paste(one fan pushing over the heatsink, and one fan pulling and exhausting. Both fans will blow the same way)

No they don't get hot at all... i had them on for over 5 hrs for a shoot and it was fine.

Mount? No, not without modifying the cooler. Set it up top? Probably fine. Not sure if it would make any difference. I'll order a 140mm fan and place it on top to see if it helps temps.

where you plug them in is irrelevant, but connecting them to the motherboard is usually preferred. if they're too loud, I suspect vibration against the case. Did you use the included rubber mounting plugs to mount them?

I love the fans. They are quiet and keep the air moving. I have a Dell studio 17 with 2 hard drives and it gets noticeably hot if I accidentally unplug the fans. I also put Velcro on the battery and stand so it doesn't slide on the tray. It's only a problem when I set it down after using it.

I installed an intake fan since my power supply has a 120mm fan that is providing the exhaust functionality. That setup seems to keep everything pretty cool (<40 C).

Hopefully, you have air slots or vents in the hotter components. If you have air vented slots on the sides and bottom, mount the fan below, if you have vented slots on the top, mount the fan unit above to draw the heat away.If you have room in the rack to space the components from each other, that is best. It is a little noisy, but works well. If you can, put the fan closest to your most critical component that is effected by heat

Never had heat issue. the air flows very well. air comes in from the front of the case and goes out from the back. and the original fans are high quality so you should have no problem with cooling!

And lol dont listen to the guy below me. I ran these in cloner tents with 99% rh and that was over 6 months ago. Moisture isnt an issue for these fans its the heat. The oil in the bearing will burn up if the air going in is over 105. Just add 3in1 oil to the base of the fan shaft while its running, with the fans blades off of course. Take care of them and they will take care of you.

I added another fan on mine and the temp. dropped about 5 degrees. It comes the extra brackets so its easy to do. I believe it also comes with a cpu fan splitter. I love mine.

No Problem...These don't take much airflow to be effective. I use to use the same setup and was never at a loss for spray. Good Luck!

I think they are 40MM fans, but in my case, I just unplugged the fans from the board, since I am running all SSD in this unit. But the plugs on the fans seem to be the typical 2-pin type. I agree, a bit noisy, would be nice if they were thermally controlled.

No fan is required, passive cooling is just fine. I run two of these 24/7/365.25 no issues.Make sure you get an adequate power supply.

I've ordered a few of these - they've all come with both brackets and they've all been passively cooled. The passive cooling was initially a problem in 1U, but if you crank the fans up to the highest airflow level, the overheating issue went away for me.

They are LEDs so you shouldn't have a problem. I didn't notice them getting all that hot. Granted, I haven't left them on for hours at a time and then tested.
