    2.2kW water cooled spindle is getting warm

    Hi guys, my 2.2kw spindle gets a bit warm when running for over 20'. I leave it running for 1h 30min and it gets warmer.
    The cooling system I use is a Eheim 600 Alpha Cool watrer pump, which is a bit small. Water pump also gets a bit lukewarm. Should I replace this water pump with a bucket of water? If so, can I get the inside part of exisitng Eheim water pump and put it in the bucket?

    Thanks.

    I have a 2.2 that I run with a bucket of treated water. It has always kept it cool for me. I was considering putting a chiller system I it but have yet to find any reason to do so.

    Define "warm"... What's the actual temperature?

    What size reservoir do you have?

    Also, IMO that pump is fine. 600LPH/150GPH seems to be plenty... do you even have a single gallon in your entire cooling system?
