  • 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 :)

Temperature?

Hi everyone after the last update to 6.3.101 I noticed that the fans are lauder after only few minutes.
My default temperature until now has been 35 degrees. Should I do another blackshade at higher temperature?
Is not very hot in Italy at the moment so I dont know if this is normal.
Thanks

If this is an Epic-W, I would manually blackshade the camera to 41 or 42 degrees. This is what we did and it works for us.
 
Thanks. Yes is an Epic W. Can I change first the temperature and then do the auto blackshade? Better the auto for me as Im covered for a bigger range.
 
Luca.

I would power up the camera and simulate shooting conditions for a half hour. Roll some fake takes, let the camera get good and warm. Then I would do the black shading. I set mine to 62 degrees.

62!! Wow--that's 20 degrees warming than I use. Maybe I should split the difference and try 52? I don't want to fry my electronics.
 
The top end is 62 with the fan control set to kick in whenever it needs to. I think the low end is 48 or something like that. I walked outside today and started sweating. It's hot here already.
 
I use my fan set to 46 on Weapon-MG. Factory preset to 42 is to noisy for me.

Anyone wants to make a Fan for the Weapon like they did for the Panavision Version? ;-)

I'll buy one!!!

I manually blackshade mine at 42 degrees as well. Seems to work well. But when I auto-blackshade at 42 degrees, I notice the sensor temp go down to under 40 (I can't remember the exact temp) while doing the autoshade. Is this normal? Because, when I manually blackshade, the temp stays at 42.
 
Thanks guys...so are this the steps?:
1. I change the temperature to let's say 40 (now is 35)
2. The I let the camera reach the temperature looking at the stop lights
3. Years do the autoblackshade

Right? Thanks

You can do that If you so desire. However, you'd get quicker boot up times (as one of the benefits), if you were to perform manual blackshade for whatever frame rates that you mostly or plan to use. As others had pointed out earlier, you could safely use somewhat of a higher temperature if need be.

When you get a chance, check this web page.

Assuming you are setting your operating temperature to your sensor temperature then Red's recommended temperature is 39C. 35C seems quite low and your fans will work very hard to maintain that temperature in hot conditions. Not sure if there is any substantial advantage at running your sensor at such a low temperature? I have never seen any tests that show any noise advantage running Dragon sensors at lower temperatures and I have personally not noticed any difference. The one small advantage is you will be at optimum temperature faster after bootup but generally its very easy to turn the camera on a few minutes before shooting.

As I live in a hot country I auto black shade at 45C for the summer months keeping fan noise to a minimum and once the weather cools I do my winter black shade back at 39C. This simple strategy keeps my camera quiet and I have never noticed any impact on sensor noise.

For me the auto black shade works just fine but set the sensor temperature first then do your black shade. The stop lights have nothing to do with the temperature just leave the camera running for 30 minutes. Preferably don't do it in a cold air-conditioned room if its the middle of summer and make sure no light can hit your sensor.
 
Luca,

You can run defaults if you like, for example if you are not recording sound, but its really best to run the camera at temperature, where you will be shooting the most and after a half hour or so, run the blackshading. That is what will give you the best results.
