I painted my PE240 and PE120 rads, filed out the holes so that the barbs sit inside and I can avoid using those pesky EK-extender fittings.

Nice one, it would be great to see an image of that. It might help me.

Running these pumps while dry for even a few seconds can damage the bearing and cause them to become noisy due to a bearing that's no longer balanced. With the way that your pump is fed by that angled fitting, I'd say this is likely the case.

I'm sure the pump did not suck in air. Despite the bend, the pump was easily saturated in liquid at all times (I can see because my pump top is acrylic).

You mention that moving the pump around didn't change the noise thing. d5 pumps are very quiet and should not be like that specially with a shoggy sandwich below it. Seem like rma time. Did you got that one new? How long have been running?


good luck mate.

Been running for 6 months.

I'm not sure how I could change my configuration in future?

Also, I've heard that once you reach a certain point in fluid movement speed, you don't see performance benefits. What speed would you guy's run my D5 at for my loop?
I currently have it set to 3.5 and it is very quiet now. Anything higher presents issues.

Thank you.

@el gappo

So many great builds to choose from for the front page! I'd like to recommend this masterpiece by fast_fate.

I like how he implemented a dual bay res internally at the bottom of the case. I'm really in awe by all of his work.

Just the air being replaced for fluid within the loop.

As Bram already mentioned,running the bearings dry cab lead to surface imperfections on the bearing which can lead to premature bearing fail.

this guy had a problem
http://www.overclock.net/t/1395198/do-90-degree-bends-in-loops-actually-affect-cooling#post_20069030
Artikbot - "Apparently so, but my experience conflicts with Martin's.
If I put a 90deg straight out of the pump or straight into it, it becomes SUPER loud. Performance is similar, but the noise is unbearable (compared to straight output/nput)."

a few posts down martin said
My test does not include pump close proximity effects. I only tested restriction losses. I have done some pumpnelbow testing, but it likely depends on the pump. In industrial pump system design practice is to avoid elbows at the pump inlet side of the pump within 4x the pipe diameter. Reason for this is the elbow can cause enough negative pressure to induce cavitation as well as unbalancing the impeller flow. Outlet is generally less of a concern.
I have measure the benefits of removing elbows at the inlet side such as going from a factory DDC top to aftermarket top with inlet elbow removed etc.
Anyhow, I would generally avoid elbows in close proximity to the pump if possible, my test was purley based on pressure drop or restriction loss.

use a double rotary 90* like this. no matter how much less a single 90* flows, this will flow better at higher speeds.

I was wondering, for the first flush of my new WC setup can I simply use boiled tap water?

Yes. No need to be at 100 C but yes can use tap water. Just be sure to flush a few times after with distil to replace any trace of the tap water.
