Ek coolstream xe - need flushing?

Hey guys.
I'm using a watercooling set up to cool the hot side of peltiers (TEC) that will be used to hold lithium-ion batteries at a set temperature for electric vehicle research.
Back when I used to watercool PCs id always flush radiators but even then the more expensive brands tended not to need it that much.
Do the new EK rads need flushing?

They shouldn't but for piece of mind it might be worth you running a Mayhems blitz kit through it.

I never flush brand new rads personally.

If anything, brand new rads are best flushed than used ones.

So many conflicting opinions, gotta love watercooling

Like VSG said, it's personally more important to flush a new rad than a used one. But I would still flush a used one too

New rads (from any manufacturers) may still have flux residues from soldering inside the tubes.

If I were you I would flush it a few times just to be sure.

Need to do my new rads is the Blitz Pro Cleaning System best way to go about it, seems to be lots of conflicting advice to flushing rads out.

I flushed my new EK PE RADS and nearly one year in, I have not had any issues. I used still water, kettle boiled water and then still again. Cheaper then Blitz and I cannot see any issues from doing it this way.

Thanks i think i'll do it this way then, cheaper sounds good

Yeah boiled tap water or distilled water is fine enough for flushing.

The Blitz kit has been created for rads like the Alphacool or the Phobya which tends to contain a lot of crap right out of the box.

I've flushed XSPC, Hardware Labs, Darkside, Alphacool, EK and Phobya radiators in my life and only had issues with Alphacool and Phobya. All the other manufacturers are rather clean out of the box.

Really? That's interesting. I didn't see too much junk come out of my alphacool rads. Hopefully it's that they were better examples and not that I didn't flush em properly!

Yeah, it's more of a lottery thing with them. So you probably ended up with a proper unit
