Quark Monster Pro Error Question

I agree with the thermal. 110f is not to warm brian.
I come up with 176 f on the temp you recorded. That is definately around the thermal range. Can you change gearing any or tried?

Sorry, I meant to write 110C. :dft001:

Anyway, I don't like ANY electronic device getting over 130-140F. If it does, it's time for added cooling IMO.

Guys,

Thanks you very much for pointing out the very thing I fear. Guess I'll be fighting thermal issues for a long time to come. I think I have killed 3 BK9920, 1 MGM160 because of thermal issues. I have 2 Quark monster pro & both of them exhibit the same problem mentioned above. Gonna have to find a big fan to try to fix the problem. A big challenge for me is that the ambient temp. is around 30 ~ 34 deg C in my area. Sigh...

Hmm, how about attaching the esc to the chassis with some thermal adhesive & make the chassis a big heatsink ? Do you think this is feasible ? I even have some left over aftermarket vga cooler with heat tube. Maybe this will help to suck the heat from the esc.

You could possibly turn the esc on its side to add some fans to the bottom where the FETs are and possibly a heat sink. :032:

Any piece of aluminum you can attach to the back o the ESC will help soak up some of the heat generated. Try an old computer heat sink and some thermal paste. That seems to be what most are having sucess with. And alot of computer heatsinks already have provisions to mount a fan.

I'm actually working on the same project right now. While you are disapointed in the fact that you have to do it, just be glad that the Quark is acually pretty easy to d it with. An nice flat aluminum back on the case. Adding additinal heat sinking to the BK warrior ESCs is much more dificult cuz theres no where to mount it.

I just got these... http://cgi.ebay.com/ws/eBayISAPI.dll...MEWN:IT&ih=020

2 of them side by side is an almost perfect fit onto the back of the Quark 125. Then I'm planning on mounting a 40mm fan in the middle. If that dont do it... nothing will.

Yup, adding a heatsink is quite easy on the Quarks. The FETs are attached to the bottom where it is flat. There are tons of ways to do this, here's one (mine :)). Believe it or not, this helped a lot. The ESC case is kind of thin (presumably to keep weight down) so it gets hot quick and there isn't much surface area to dissipate the heat. Add mass to absorb heat, then add surface area to get rid of it:
