Cooling Demineralised water even when testing?

I gonna be getting my first water cooling kit in the next few weeks. The thing is, I'm not 100% sure how I will set things up. I think you should use demineralised water for the coolant.

Would it be a bad idea to use ordinary water when I'm just testing the set up?

The reason is becuase I'm in two minds as to whether a) I'm gonna build a custom perspex case or not, and b) if I do build a custom case, how it will be layed out.

If I go the custom route, I see myself doing lots of moving things about.

 

moving to extreme cooling so the experts can tackle your question... eddie_dane

 

Distilled water is cheap. I would use it even during testing. That's just my thought on the subject.

 

yeh always try and use distilled water where possible. if you did use tap water whilst testing then make sure you completely flush it out with distilled water beofre use. but still i would not recommend use of tap water for any length of time as your blocks and such can quickly become filled with nasty deposits of grime.

 

Like said if you use tap water flush it out pretty good...I used to flush with CLR *calcium lime and rust remover*

 

Do not use CLR to clear out copper blocks, its on the label. You can get distilled water very very cheaply at most pharmacy/supermarket/etc. Cheap insurance I think

 

Many thanks.

If things go according to plan, you'll see a lot more of me asking more n00by WC questions.

 

Anyone ever try deionized water?

 

yeh i used deionized water with water wetter in my system and it works fine
