  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Fan noise

So I'm wondering what those out there with a Red think of the fan noise. I'll principally be using the camera for documentary work, so my likely shooting scenario will be:

2k
long takes
no blimping or passive cooling (think ice packs) possible

From those out there with their Reds, is it possible to run the camera for fairly long takes without the fan on, assuming an ambient temperature of the mid-70's (just as a hypothetical).

Thanks!

How many DB are we talking about here? Are you saying this camera would need to be blimped?

I'm not saying the camera would need to be blimped David -- I don't have one yet, which is why I'm asking this question to those that do have one. From what I've heard, at its highest setting, the fan noise is noticeable. I'm assuming that at this highest fan setting, the camera would need to be blimped if the mic placement was nearby. So my question is: can the camera be run for extended periods without engaging the fan, and, if the fan does have to be engaged at some point, are the lower settings of the fan inaudible. Hope that helps,

Hi,

The default for the fans is on whilst on standby, when you record they turn off. Nothing to worry about IMO.

Thanks,

In reading these post I have read that the camera has a viewfinder heat warning alarm for heat so I am sure you might have some control over the fan. But after the shoot in Spain this summer the body was redesigned with more heat sinks so I would expect that this would help limit how often the fan comes on.

You might be able to turn it right off and just operate with viewfinder warnings. Not sure, I don't have a camera here but I am trying to share knowledge.

David
 
Thanks for the info guys. Until we have larger CF cards, I guess it will be impossible to know how the camera's heat performance will be with long takes, but it sounds like Red has done a good job of keeping the fan as unobtrusive as possible. Does anyone have DB ratings on the fan at various speeds?

Hi Stephen, hehe, you be a RED adicted now? Back from IBC, bought for my "on the fly" work the x15 from Panther, it is a lovely piece of lightwighted head.
 
Hi Daniel,

Stephen and I had a look at the panther stuff. Nice unit you've got there. Let us know your impressions once you get to doing some "on the fly" stuff.

Hi Paul,

I was driving to a shoot on Monday morning & Daniel called me asking about the Panther, I said I thought it looked pretty cool for 4000 euro, as you know there was no small O'conner to compare with.

Hi Daniel,

Thanks for that, look forward to testing that Panther head real soon on 222.

Stephen (I am sure many people think I should own 666)

I think the question is worth it, simply because they can't keep being switched off. Something is heating.
Somebody at RED booth NAB told me they will slowly go up if temperature rises.
And they have to. Either switching camera off or cooling. Staying switched off is no real option.
Am also curious how loud they will become.

there are plenty of guys using the camera in warm/hot weather who can answer this, I hope someone can fill us in.

for some years now people have been making silent PC cases that dissipate 100s of watts either very quietly, or absolutely silently, so I think there are external solutions out there that can be applied if need be. Would add some size/weight/power draw to the camera.

Hi,

Ultimately the picture will get noisy if the sensor gets too hot. The fans can be set to stay on at a lower level if necessary. This problem exists today in other digital cameras, it's not anything new.

I listened to the RED cameras on the booth at IBC and the fan noise didn't seem too high. I think for documentary work your primary concern will be changing batteries without having to turn the camera off. Oh - and switching CF cards.
