C500: I went ahead and did a C500 Fan Noise Quick Video Test - See Vimeo link & talk?

My fan unit came with a Switronix Powertap (D Tap) Regulator cable for the Canon C300/C500, 8v output, 4A. Model XP-DV-C300 This also had an Lemo connector for the fan unit. I'll post pics on the weekend.
My fans are super quit rated at 18db. 6500 rpm. ADDA ( Fan model discontinued ) I'm sure there is a newer comparable fan. It's nice to have the Lemo connector, as I can alternate between running of my Dionics, or a 9-12v other battery source.

My unit is exactly the same as the original with the optional Switronix powering option.

I had looked into the fan and like you said, it's no longer available. That is unfortunate because it's 35mm x 35mm x 6mm. I could not find another fan that thin. The fans I found are all 35mm x 35mm x 10mm. It's not a huge deal to me as 10mm is not that wide. The one I am using is rated at 9000 rpm which would account for the higher db of 34db @ 12v. I have run both 12v and 9v power and the fans I used are much quieter at 9v.

C-Mac, here is a site I found that sold the original fans, there is a link at the bottom of the page for similar fans!

http://www.mouser.com/ProductDetail/ADDA/AD3512LB-K70S-LF/?qs=osVJq4lsVJdtE78cdWBG8A==

And here is the closest fan they still sell on this site that matched the original fan.

http://www.mouser.com/Delta-Electro...-dwatbZscv7?P=1yva230Z1yd157mZ1yd1519&FS=True

And two more on the same site slightly higher DB level.

Thank you B. Berry. It's nice to have a quiet C500, LOL.

There are some good fans here... I purposely avoided 5v fans in favor of the 12v.

The ADDA that was used by CineAbel has a low db at the expense of pretty low air flow... what concerns me is if you end up in a higher temperature environment the better air flow of other fans may be advantages to keeping the fans from turning on... I don't think that should be an issue based on Matt Porwoll's comments, but you never know... I tested a 6v battery with my fans and noticed the temperature warning light came on... so less air flow equals higher risk of internal fans Turing on. With that said my fans tested almost unnoticeable to the lav and nearly so with the shot gun mic in a very quite environment room tone test. At 9v my fans are likely running around 26 dBA maybe less. I feel pretty good about it.

Thank you B.Berry.

Best Regards,

Chris

I would mention that B.Berry got the last one at AbelCine.

If you have a drill with metal bits, a jigsaw with lubricating grease and a blade for cutting "thin metal", gloves, eye protection, electrical tape, and you are handy, you make on of these for around $50.

I also needed:

Card Stock paper
Scissors
22 gauge steel sheet metal - (I bought 12 x 18 inch size as that's all my Home Depot had in stock) - $12
2 - quiet 35mm x 35mm x 10mm fans - $20 for both. I bought these:
https://www.amazon.com/Evercool-Eve...id=1477567459&sr=8-3&keywords=35mm+x+10mm+fan
1 - 6 AA battery power caddy that runs the batteries in parallel equalling 9 volts (You can also use 1 - 9v battery, but it will have a shorter life than 6 AA batteries, my tests showed that 1 quality 9v ran both fans for 1hr 40 mins without running out.)

Cutting Sheet Metal this thin and small is a bit dangerous(you should use gloves and eye protection), so if you are not comfortable with this don't do it or ask someone who knows how to use a jigsaw properly.

I wish I had a grinder as I would grind the rough edges a bit. I used my hand files, but it's not the same. I wrapped my unit in rubber tape to help prevent scratches on the camera body... I may pick up a grinder and grind and paint the metal part.


I used card stock, traced the original plastic cover for the SDI Ports, then cut down until I felt it fit properly. It was a hold on the camera, trim, hold on the camera trim... I did put the center hold in it early and kept that as a guide.

I carefully placed the fans and traced a guide. You only need the metal piece to attach 2 screws on each fan, see the image in the video. It's a pretty small piece of metal.

Once I had cut and drilled the holes, I used a rubber hammer, pliers, and needle noise pliers to bend and form the metal to the camera.

I would estimate it took me an hour and a half to fabricate the part.

I would also note that I was able to use a wall putty like tape and electrical tape to connect these for the test... it's not as solid if you are running and gunning, but you could test it and that might be okay for some people. It's also very easy. Mine stayed on the camera this way for 2 days while I did my initial test. I had to remove it, it did not start falling off.

I apologize for my stream of conscious writing! If you have any questions, I can try to answer them.

Best Regards,

Chris

Get yourself a Dremel. It's ridiculously useful for all sorts of little projects and is fairly cheap to own. The kit comes with some grinder wheels.
 
C-Mac, I'm sure we are close to solving the fan problem on the C500, we just need to be certain about the lowest voltage we can run these fans without getting above 77* on the inside of the C500.

I'm swamped with work stuff till afternoon Saturday, more testing after then. Most of the work has already been done for us.

I would say it had already been solved with your device and I was just working back to that point.

I placed mine next to a gas fireplace and the remote tested 88+ degrees. The remote was placed on the camera. Everything seemed fine and no thermometer warning turned on inside the camera. I can't attest to the accuracy of the fireplace remote control's thermometer but it started at a temperature close to the house's heating control thermometer and it was right next to the fire place. Fortunately it did not melt? I stood next to it the entire time, just a little nervous, LOL.

Where did you come up with the number 77 degrees for the internal trigger inside the C500? I would have thought it would need to get a good bit hotter than that before the fans would trigger?

On another note: It's nice you can be plugged right into a main power sources, but I can like run both fans for a couple hours or more (only tested for 1hr 40mins) on a single 9v battery. They are not very heavy and are easy to place on the SDI port area's upper ledge. I am planing on running them on a 6 AA caddy at 9v with rechargeable AA batteries.

This has indeed been a helpful thread for me and hopefully others!

It's good to be swamped.

Thank you B. Berry.

A Question guys. being a C300 owner, i know there was a free service from Canon for Sealing the sensor..... there was something wrong with at the beginning and as i understand the dust was getting on sensor..... back then i used that offer for a free service...

but now after all your experiments guys with external fans.... Was there same kind of sensor sealing problem with C500? was Canon offering same free service..... or C500 never had a problem like C300 had?
just asking as the air flow with external filters is going to be much stronger.... means its possible that more dust will be able to get inside...
 
Hi Guys,

UK People, There are some offers around for 24 Months 0% on the C300MKII. I think I will go down this route now as it works out cheaper and more modern tech.

Just thought I would put this forward to you.

Thanks
 
Wow Chris that fan noise is very noticable. Thanks for doing this. I would imagne a simple background filter would mask most of that.
The image on the camera is stunning and probably worth the effort to modify.
