View Full Version : Mamba Max heat sink

I was looking at the heatsink on the Mamab Max today and it appears to be attached in such a way as to not allow removal. I was wondering if there was some way to remove it to make way for a bigger heat sink. I have had no issues with thermalling but I have seen some really cool heatsinks in my local computer store and would like to find a way to attach one. You know what they say, cooler is always better. Also, is there any effective heat sinks for an Associated T4 that I can run with the stock motor guard being kept in place. I am thinking my only option other than runing wthout would be to glue some small sinks onto the motor mounting plate.

You could attach the heat sinks on top of the original ones>

Looks likes attached with thermal epoxy. Its as simple as heating it and prying it off with a flathead screwdriver.
I have removed heatsinks from some computer motherboards(i tweak computers aswell as RC stuff). but those chips are bigger and the ones under the mamba looks pretty small. you could run the risk of pulling the things right off the board.

Ummm... I would leave the sink alone... but if you want to be the guinea pig, at least tell us if you destroy it or not. ;)

Is THAT how you get thermal epoxy off...just by heating it up? Maybe I should....investigate this....:D

hey, just so ya know... when you do that you run the risk of taking the top layer off the chip!!

Yeah, I reasearched it and read that somewhere. Obviously it must be done VERY carefully. I need to find something to experiment with before I go diddling around with my ESCs though....:D

No, don't heat it up, throw it in the freezer!!!! Throw it in for 15 minutes, and then pop it off with a butter knife, just be careful not to cut any traces on the pcb. I use this method for video cards all the time, the heatsink usually comes off clean with no need to scrape crap off.

actually both ways will work. heating or freezing it. I heat it because leaving strange things in the freezer will get me yelled at :p
you will always run the risk of poping a chip off aswell, so go at it slowly and watch out for the Pcb. use a card of some sort to prevent scratching the board. like this http://users.rcn.com/chinmonster/pc/hs_remove.jpg
wont you void the warranty by doing so?

Is that an old ATI Radeon 64mb card? I think I used to have one of those. That is until my water cooling system blew up because I forgot to turn the pump on. It was a very reliably card from what I recall. Just not water proof. Oh, well.
If you do manage to get this HS off, perhaps you can install a heat-pipe. That would be a site to see.

Yeah a heat Pipe, with velicity stacks, and a tunnelram :eek:

That worked like a charm. It took some fighting, cursing, and blood, but I got my SS ESC's heatsink off. I intend to replace it with a MUCH larger unit....:D I'm also going to use some of that arctic silver thermal epoxy stuff as well. The original heatsink was stuck on with that thermal pad crap. :eek: (Yes, I know, warranty....down the toilet....big time):D.
It won't be as easy with the MM I would guess. The way the Novak's heatsink is mounted, it's actually sinked to the BACK of the FETs, directly to the "bottom" of the PCB board if the FETs were facing up (which they aren't, they face down). That's probably why I broke nothing in the process (amazingly).

watercooled esc!! that would be swt(geek wise). I might just have to do that.... :cool:
never have any problems with my pump. I used a 12v relay so it turned on with the computer. ;)

Use Artic Alumina it's electrically non conductive.

I need to find a local store with that stuff in stock. No body has it on their sites. I really don't feel like ordering it either.......ahhhhhh! :rolleyes: Thank you for the tip as well. It'd suck to short out the ESC huh?:D

You would be lucky to find that stuff locally. I got it at this place. http://www.hardwarecooling.com/product_info.php/prod/415/Arctic_Alumina_Adhesive

I found it from a bunch of places, but most were online, and not local....which pisses me off. I'll check if Tiger Direct has it. My dad works not too far from there. He can probably pick me some up if they got it after work.:D
