Fan recommendation
Hi all,
I would like to put a fan in my casing (http://at.rs-online.com/web/p/oszillosk ... e/8194077/)
Is there a recommendation for any fan that fits good in the case?
cheers
Florian

Re: Fan recommendation
The distance betwen mounting holes on my acrilic housing is 33mm. Based on the power suply(5V USB) Red Pitaya has, i would go with this fan :

Re: Fan recommendation
Finally I bought this one:
http://at.rs-online.com/web/p/products/7588204/
Sunon MC30060V1-000U-A99, DC Axiallüfter Vapo-Lagerung, 8.33m/h, 5 V dc / 0.56W, 9500U/min, 28dB
It fits well, although it does not fell like it provies a big air stream.

Re: Fan recommendation
There is a new printable case for Red Pitaya that fits the board well and also enables the fan mounting.
available here : http://www.thingiverse.com/thing:820727
It would be awesome if you would try it and give me some feedback so we can make it better!

Re: Fan recommendation
Another approach that keeps the Red Pitaya very cool is to use thermal pads and a large aluminium sheet. It runs colder than skin temperature 24/7. No fan needed.
Here you see the square thermal pad between the Red Pitaya heat sink and the aluminium sheet.
Of course you need to cut a hole in the PCB for the thermal pad.

Re: Fan recommendation
Could you tell me a bit more thermal pads? I am thinking about building fanless aluminum enclosure, but I'm hesitant about ripping off the original heat sink.Karri Kaksonen wrote:Another approach that keeps the Red Pitaya very cool is to use thermal pads and a large aluminium sheet.

Re: Fan recommendation
Sorry for late reply. There is not much to tell. 3M has thermal pads that can easily be cut with a knife. I used the original metal heat sink and a 3M thermal pad. The pad has glue on the other side and it is soft. It transfers heat nicely from Red Pitaya to the aluminium sheet.
The next project is probably to make an adjustable analog amplifier and offset regulator to get the most dynamic range from the board.

Re: Fan recommendation
Thanks for the reply! I mounted an RP board on about 16x8X0.3 cm cast aluminum box cover with a chunk of copper and a thin thermal pad. The cover seems to be pretty warm to touch, I'd guess ~45-50C and reported RP core temperature is in the 56-58 C range. Is that considered acceptable?Karri Kaksonen wrote:Sorry for late reply.
