Kosmik heatsink with fan.

jamin_00 · 12-22-2012, 08:16 AM

Just arrived.

It simply plugs in to one of the sensor ports.

Just need to know what side and wheres the best place to put it?

jhheli · 12-22-2012, 11:10 AM

I would but it in the middle on top where the fet sits under, the whole top area serves as a heat sink for the fet, its a nice compact unit.

Can you put a photo up Ben?

How are you planning on fixing this to the ESC?

Wh1teAfr1can · 12-22-2012, 11:12 AM

The fan goes on the top side of the esc where all the labeling is and dead center

jamin_00 · 12-22-2012, 12:41 PM

Cool.

Will prob use thermal tape so it wont ruin the finish on the Kosmik. I cant upload pics for some reason, keeps timing out???

malc1 · 12-22-2012, 12:46 PM

Was wondering about the thermal tape - are we sure that this won't leave any sort of marking on the Kosmiks surface?

I've just seen the timing out message as well????

jamin_00 · 12-22-2012, 01:03 PM

Even if it does it will be a lot less than using Artic Silver thermal adhesive or the like

malc1 · 12-22-2012, 01:13 PM

Yeah I suppose you're right about that.

Wouldn't mind knowing though from anyone who has used the tape before.

Thermal tape comes off clean atleast the 3M 8815 does. Heres a pic of the FETS

What thickness would you recommend?

Magneto · 12-22-2012, 03:36 PM

8815 is very thin 15 mils. and works great .

malc1 · 12-22-2012, 03:42 PM

Thanks Magneto, useful information here.

jamin_00 · 12-22-2012, 03:48 PM

Yes, thanks Magneto.

Malc, found a place here http://www.digikey.co.uk/product-search/en?FV=ffec1f96

malc1 · 12-22-2012, 03:51 PM

Thanks Ben.

smsodhi · 12-23-2012, 03:02 AM

By using the heatsink on the helijive/jive you can increase its amp rating. Does the same apply to the Kosmik as well?

jamin_00 · 12-27-2012, 12:42 PM

No, in a word. The Kosmik can go over 200a. It can peak much much higher but if it hits this max, even for a millisecond it will shut down. Having the heatsink/fan will aid in the cooling which will help to delay it shutting down if you are driving it hard

rebeltrousers · 12-27-2012, 03:26 PM

So the Kosmik 160 has a ceiling 40a lower than the 200 in a spike??
Where approx is shutdown??

jamin_00 · 12-27-2012, 03:28 PM

I do not know at what value the 160 will perform a hard shut down.
