Biggest Noob Mistake Ever? Flushing!?

[Rubycon]

Rarely see this discussed but if parts have this much "gunk" in them wouldn't that just foul up those channels in your blocks?

Watched this and the pictures at the end are scary indeed!

WOW, how does that get in there?

This is a good reason why I flush every new/used RAD with automotive Prestone Super Flush and distilled water.

Nothing a good hot water flush wouldn't fix/prevent.

Thermochill rads were the worst for leftover flux.

why is he plugging in a filter?

Dude his methods are funny.

Guys easiest way to flush a new rad is to just connect it to a faucet, and then let it rip.

Your City waterline pushes water @ 60psi or more, which is far better then his model because u are not going to get undisolved gunk out of the system without the sufficient amount of head pressure.

Thats way more then enough head pressure to force out gunk, then his pump and filter.

You let it rip for about 45 seconds.

After you do that, you then fill the rad up with distilled and empty, and fill it again, and then empty to flush all the tap water out of the rad.

Then YOU ARE DONE.

U dont need no bucket.. u dont need no pentak filter..

Dude... the way things are going pretty soon people are going to say u need to tie up a UV sterilizer + then autoclave it.

:\


Anyone want to take a guess who's lc'd more? The guy in this video or me?

Here is my take on this matter. First of all I don't claim to be an expert in anything much less pc watercooling!
What I do know and have experience with is water cooling high power laser heads and power audio amplifiers. All these devices use fully active filtering. The waterblock pictures that I have seen show some pretty fine chanels and these look difficult if not impossile to rid of foreign object debris (FOD) without damaging them.

That said flushing radiators is recommended to remove bits of stuff from assembly.

The blast of tap water may be effective at removing things that may settle out at lower flows however tap water unless micron filtered itself is going to possibly be a source of particulates. This does not take into consideration of high mineral content (hard water) or even acidic water if drawn from a well. As long as a flush with distilled water is done to follow up the "tap water blast" cycle, it would probably be OK.

Using a pump to recirculate water through a radiator and filtering it with a 1-5 micron filter is definitely not a bad idea. Sounds like a real good idea to me!

Installing one of those filters on a PC watercooling system for full time straining would be a good idea too. It may be too big to mount in a case but smaller filters are available. The large filter used in the video would never impede water flow until it got really dirty and once the water is polished it will stay that way. The neat thing is one can place time release treatments in the center of the cartridge if needed.

It is a good example of what you see in the crud. That green stuff is oxidized material, which is why I personally use a corrosion inhibitor. I'd gladly give up a few percentage points of performance for less cleaning and longer life.

errr which is why i said u flush with distilled after.

Filling the rad up, and then emptying it allows the distilled to replace the tap after serveral flushes.

Adding a filter to your system is just increasing cost.
Dammit ive LC'd for 10+ yrs... and not once used a filter on any of my systems.

Preping a LC system is not this complicated... if you want to make it complicated, then lemme introduce you to my tri loop system.
Thats about as compilcated as it should get.

Yes but if you flush with DW first...

Cost? We're talking $100 at the most. If a system cost $30,000 to design and procure that's a drop in the bucket honestly. Commercial systems use filters and I trust their engineers know what they are doing. You have to understand these are products that must be reliable and tearing down every couple of months is unacceptable. You could build a PC WC system that could run very long and not have to be torn down too.

Three loops isn't complicated, it's just duplicating things. I've told you what complicated systems can be. PC watercooling isn't one of them.
