EK-CoolStream XE 360 Leaking (one week old)

post #1 of 10
Thread Starter 
Hello,

So I've gone through a bit of an ordeal with this new loop I'm putting together. I ordered the EK-KIT X360 and a EK 780 Classy Waterblock for my GPU both from Performance-PC. The waterblock arrived shattered, and I've gone through the steps to have them replace the plexi. I thought that's where the ordeal would end... but now the radiator is leaking. I looked around and saw some videos about this particular model. Dazmode has an unboxing and showed that it had a shroud. I decided I'm going to see what's under the hood and see if I can plug the hole somehow. Here's what I found:





Does that seem right? This much discoloration in a week? /perplexed Dazmode's video showed the radiator as completed painted and in pristine condition.

So I've contacted PCP and EKWB, let's see where it goes from here.

P.S. the Vardar fans have a droning noise like a hive of bees are inside the hub... not impressed.
P.P.S. I'm using a 900/100 mL mix of distilled water and the additive that is included in the kit.

I would just Rma the whole kit.

Although it doesn't look nice, can we speak about the leak first.

From where did it leaked? Can you show me a picture of the leak and explain me how it happened.

Its not discolouration as such, its just raw brass and copper that has not been fully painted. One point of the shroud is that the insides don't need to be painted and indeed some of the other models get none at all under the shroud. Paint is just an insulator, which we don't really want on a rad except for the external parts.

The leaking is of course not acceptable though. I didn't notice any damage, can you just fill the rad with water like it is and see if you can locate where it might be coming from. Even better would be to use air to test if holds pressure.

If it is leaking it needs to go back.

It was leaking from the corner of where the EK symbol was on the shroud. I couldn't locate the leak, so I've tried to install it upside down. No leaks so far.

Could we address the discoloration and the loud fans? These fans drone really loud (almost resonate) at low rpms. The sound is louder/more irritating than my Noctuas at full RPM. I was told these new PWM Vardar's were really good. Could I have received a bad batch? All three make the same drone, but slightly different tones. So all three drone on a slightly different frequencies making it SUPER DUPER annoying.

I had my fair new XE 360 apart too, and mine was all black with no copper showing on the end-tanks, but on the fins less paint is better for heat dissipation.

But i would think you got a rejected radiator that failed the 1 bar pressure test EK claims makes on them, would also explain why it has no paint on the end-tank. So RMA it.

I bought this from PPCs and in a kit. Do I have to RMA the entire Kit? It's already partially installed and the tubes are all cut up. Also, who pays for RMA in a situation like this. I don't believe I really should have to pay a cent if this a refurbed radiator that they somehow mis-represented as being new.

About the fans, are you keeping them at no less than 50% power cycle? These are Vardar F3-120 and the power cycle on them is 50%-100%.

About the RMA for the radiator or the entire kit, I will ask.

The fans drone at all RPMs via SpeedFan. I don't know why, but I expected them to be quieter than my Noctua F12s. At this point, they are quieter than my Noctua industrial 14s, but the noise signature is grinding. /shrug

Ok, the best will be to contact PPCS (since this is where you bought the kit) and ask them if they would accept to RMA the radiator and the fans instead of all the kit. Hank (the guy who usually handles the RMA) will probably just RMA the faulty parts instead of the entire kit.
