What about fan speed?

[Karl Krings]

Hey,
its possible to runs scarlet on lower fan speed? maybe constant on 50%? for me 75 and more is really noisy :)
...or will i grill the chip when i lower it permanently etc.?

thanks

I guess it will depend on the condition you shoot, just back from a 4 days shooting in Sumatra rain forest with 43 degrees C and almost 100% of humidity, you can be sure you need more than 50% fan speed in this case. Maybe try in Auto fan mode and see what speed it goes in the condition you shoot first before fix the fan at one level.

thanks. we are here at 15 degree a little sun outside. inside about 20 degree. fan starts low at 50 and after 3-4 minutes its rise up to 70-80. is there a safety mode for the camera to shut down when its too hot?

it will not shut down, when it gets hot auto fan speed will override your manual settings and it'll kick in full throttle, after it cools down the sensor fan speed goes back to your manual settings.
i hate that fan noise, but i just recently found out that on C300 fan is even louder, and it's speed is not configurable if I am not mistaken.

hey. nice. so i can set it down to 50% manual? if the cam gets too hot it will automatically be safe. So i can not kill my cam?

I didn't know that, interesting, thanks for the info !

For the small story, on this shot in Sumatra, the production impose to shoot with 5Ds... And guess what, with those extreme conditions the 5Ds collapse due to overheat many times... The producer was pissed and my only answer was: Well what do you expect from a $3k non broadcast camera? ...
My scarlet in the hand of Fedex right now and soon in mine! Look forward to test it in those extreme conditions ! ;)

i do own mine since monday ;) testing and adjusting all stuff...using beachtek audio I/O. also works fine at the moment... patrick: what was your maximum brain temp. you had?

I had the same concerns so I ran a simple test. I set the cam for manual fan: 35% record, 80% Standby. @ 35% it was barely discernible to the ear from 4ft. I hit rec and maxed out a 128GB SSD @5k, 8:1RC (Epic). It ran for about 20 minutes before the fan kicked in at 106% the temp was 75C. It lasted only about 10-15 seconds and then kicked in one more time 4 minutes later before my card was full. I'm pretty certain the Scarlets are the same, but if you have 20 minutes, don't take my word for it, give it a whirl! (esp if you live in a warmer region) Ambient room temp was 70F.

[Karl Krings]

ok. try it at 42% while recording and 55% while stand bye. so 75% it will pump up to max fan speed to prevent overheating. so important is not to smoke it up ;) if this won't happen i am satisfied. can you confirm that? thx

[Paramon Ivanovich]

no, i am done with my testing :)
if I know i will be doing long shots I keep it on auto, short ones at 25rec/75stdby, also , like Timur noticed, long shots with higher fan speed get you cleaner image,
you just need a longer lens :)
