Has anyone thought of using a PC radiator to cool your spindle vs using a submersible pump. I am not sure how fast the pumps can move the liquid. I like the idea of the system to be closed vs open.

I imagine it would work fine, however, I’m not sure how much the radiator and fans would appreciate living in a dusty shop. “Anything with a fan is a dust collector.” — some wise woodworker

I have thought about the same thing. I have a number of Thermaltake radiators that I wouldn’t use on a computer. They are aluminum so I don’t know if they would react to the waterjacket of a spindle. By chance are the waterjackets stainless steel? I don’t know.

Hey DigiDigs, [image] DigiDigs: Has anyone thought of using a PC radiator to cool your spindle vs using a submersible pump. A passive radiator would not be able to remove enough heat from where it is produced, i.e. inside the bearings. But if you think of a water-cooled gaming PC with its ra…

It was never my intention to imply a lack of dust collection. Despite all of my dust collection efforts and air filtration, there is still a small amount of lingering dust in the shop, mostly from tools other than the CNC or simply hand sanding. I blow out the shop daily with a leaf-blower to ensure…

Hey Matticustard, you are right with admitting that it’s difficult to suppress any wood dust, since otherwise in the industry they would not have their mechanics enclosed in rubber bellows , e.g. like here . But I have seen that many people here use a shop vacuum (often with dust separator) which I …

I should have said I like the idea of using a pump and reservoir sealed and not to use a bucket.

I used an aluminum fuel cell as my reservoir assuming the metal construction would radiate heat and it has an ice well I figured I would fill up if needed - have never needed to and I run a 2.2kw spindle. I’ve never had the temp probe on the tank get above 40C but I am in a air conditioned space.

I installed a three fan PC radiator that is mounted to the x rail gantry. It takes 12v @1.5amps. You can use a plug in adapter from Amazon for a few bucks. I also added a flow indicator and small reservoir where you fill the 50/50 mix. I always use dust control and the fans do not see much dust. Yo…
