I don't know. I do know that I did have one motor fan that was 4 little legs above the heat sink, so the fan was floating. I broke 3 fans in that truck before I did away with it. Now I run the crappy castle fan holder which is just plastic and it seems to do ok, which doesn't make a lot of sense as the fan is floating still. Only thing I can figure is that the plastic flexes a bit and absorbs the impact whereas the alloy one I had before didn't flex.
The HW heat sink/fan I have now has the back of the fan resting on the top of the fins. It's been on there for 8-9 months and I haven't broken the fan yet.
I think @Mr.Duke made a fan mount for his and had issues busting fans apart as the back was all open. It think it was him. Now he's using fans that have an aluminum housing. I haven't heard how that's going yet.
Yeah, it was him:

I don't have the skill or the tools to make something like that. So, I'll stick with my $10 heat sink/fan combo as so far, it's held up fine and it does drop the motor temp by 20-25F in general. Helps keep air moving under the body when I'm just futzing around at the skate parks and park. I don't do a ton of WOT running, just a lot of 1/4 - 1/2 throttle with blips of WOT for flips and whatnot.
New fan setup has been holding up perfectly so far in the Talion but I don't beat on that one like I do the Outcast.
Outcast is waiting for a bigger ESC/motor combo and down for another week or two. IMO that'll be the real durability test for the fans, but they're way beefier than the WTF fans I've run in the past
