Default Mounting a fan to Novak Havoc Esc

I bought a fan to mount to a novak havoc esc and do not know how to mount it. It has 4 mounting holes for screws but my havoc has no holes to mount it to. Do you need some kind of bracket or something?

No need for a bracket....the outer-most 'gaps' on the heatsink are designed for a 4-40 size screw to be threaded into them. There are small grooves that run the length of the heatsink and are spaced to catch the threads of the screw. The GTB and SLYDR are the same way.

Thanks, I also see in the picture it looks like I see some sort of spacer in between esc and fan, is this needed or can I install fan directly on top of esc

You 'can' mount it directly to the heatsink....I believe the spacers are there to provide a bit more airflow through the heatsink, and to keep the fan motor a little above the ESC to protect it a little from the heat.

If you're using the ESC/fan in offroad, I would suggest using the 25 x 25 x 10mm fan. (Novak part # 5647). It's very durable and keeps the ESC cooler, compared to the white fan in the picture. You'd mount it using just 2 screws on one side of the fan, in one of the heatsink gaps. Since it's a little smaller than the white fan. I run one in my B44 w/ a GTB and it works awesome!

On the a GTB, Novak uses plastic 4-40 screws. If you use metal screws, you will mar up the heat sink...

Mine are metal right from Novak....Out of the box Novak runs the fans leads under the fan, so if you run without the spacers you'll need to run the wires on the outside. The white fans are JUNK I have 3 and none have all their fins on them.

I'm looking to buy a fan for my B4, I'm running a Novak Brushless system with the Havoc esc. The body on my B4 hits the ESC now as it is, is there anything I can do to get rid of this problem? Thanks.

Depending on the fan you get, the spacers are necessary to keep the fanblades from hitting the heatsink fins.
