water cooling options for spindle

[routercnc]

Thanks Guys, some useful stuff there.

I had considered fish tank pumps, but not sure if they would be up to it. If anyone has seen one used for this application, or seen anything suggested above actually used on a spindle, I'd be interested. Same goes for fountain pumps, high flow rate but would probably get hot with the restriction in the spindle - they are not very free flowing. Some people have tried windscreen washer pumps, but they did run very hot connected to spindles. I did consider running several together, but it feels like a bodge. Probably not as quiet as a PC cooler pump either.

Hi ecat, great stuff. Love the spreadsheet, would be great if there was a spindle option for the CPU block! I'd seen the silver strip idea to stop things growing in the water - was probably going to use a proprietary fluid of 25% proplyene glycol with anti-corrosion and anti-bacterial, but no harm to add that as well.

I've seen alot of the Thermaltake stuff around and thought it was respected, but perhaps there are better things out there, as you suggest. Thought this post might bring out some overclockers ! Thanks for the other options, I'd also considered a simple pump, radiator and T filling junction, but also like the idea of a reservoir to give more water volume and a bit of extra cooling. More water should allow me to run longer if the radiator and pump is a bit underspec.

So it's all a bit of a guess at the moment. These are the figures I think I'm looking at:
1. Don't want to spend more than £90 if possible
2. Want something to fit and forget - don't want to spend hours fiddling
3. Probably looking to dissipate about 200W, although I'll go with Jonathan's 300W
4. Prefer to run with a litre or so max because I'd like it all self contained near the spindle and water weighs ~1kg per litre!
5. Don't want the pump or fan to make too much noise - otherwise I'd have been better off with the aircooled version and this project is about a quiet overall system to replace that noisy router.

I'll do some more digging and if I take the plunge on something and it works I'll post it out in my build log.
Thanks
