MM temps?

What are you seeing on temps on your MM esc. I would like to compare temps with others around so I know if I am having roll issues.

I ran my 8T 4s 1515 1yf 13/48 non modded MM and was up to 175f in a short time (like 5 minutes of track time) Motor was at 110.

I do not have a fan on it yet so I am assuming fans on a MM are a must. Please post up temps you are seeing.

Thanks
