Default What fan size?

Hi guys i wanted to ask what the fan sizes are on these two heatsinks? and had anyone tried either one and do you think they are effective in cooling brushless motors?

first one is an eagle racing heatsink, the 2nd is a LRP one

Thank you and a happy new year

Never use them so I don't know how well they work. The LRP has a

40mm x 40mm fan. Not sure about the Eagle racing but my guess would be
30mm x 30 mm

The Eagle racing one works great. It does the best job of any heat sink I've used.

I hvae 2 of those LRP heat sinks. They reduce the heat of a motor by a 1/4 well worth 35 bucks

Being the computer geek i am, i know that bigger surface area and a bigger fan will almost always yield better cooling options , so therefore i've gone for the LRP heatsink.

Thanks for help, and a happy new year

A bit off topic but ... have you tried using thermal paste between the motor and the heatsink? Does it lower the motor temp in real life?

Thermal compound works. Just take some 0000 Steel wool and polish the contact surface.

On my novak motors I have used thermal grease between the stator and purple ring. Seems to draw a little more heat.
