Flushing brand new cpu & gpu blocks?

[shadowman007]

I know it is recommended and am sure everyone does it flushing their new radiator(s) but what about flushing a brand new gpu and cpu block? I mean is it necessary?

i have no experience in watercooling, but i'd say better safe than sorry.

as long as you've got your anti-bacteria thing in there it should be fine. I never flush stuff (especially for customer builds because it takes too much time) and have no problems.

Radiators should be flushed, lots of them have crap left over from manufacturing, cpu blocks and GPU blocks, eh.

There is the odd chance that you can get paint or other materials in the radiator. Although it shouldn't happen, there is the small chance it's there and it can cause issue's down the line.

 

If your spending your hard earned cash on a custom cooling loop then I would personally flush the radiator's to ensure that they are clean.

 

It's your choice at the end of the day.

Blocks don't really need to be flushed since they are cleaned before assembly but giving them a rinse with distilled water isn't bad. Radiators however have to be flush clean both directions and shaken up to ensure it removes particles and flux from manufacturing. You can do it with tap water and do a final rinse with distilled.
