Heatsink and fan combo for Castle

[Brokennib]

Does anybody have any recommendations for a heatsink and fan combo for a Castle 1650 kv motor?

Arrma Kraten 8S heat sink #ARA390296 and Kraten 8S 50mm fan #ARA390295 will fit but from what I’ve learned here its not needed because the 1717 and MMX8 combo run very cool.

Yeh in a Kraton EXB with an 18tooth pinion, it gets hot running on 6S
