Seidon 120v problem

[Stefanism]

Hi, I have a bit of a problem with my new AIO water cooling.

I was cooling my i7-6700K (stock speed) with a Cooler Master Hyper 101 ( http://www.coolermaster.com/cooling/cpu-air-cooler/hyper-101/ ). Idles around 27-32 degrees, tops at 65-68 under load from AIDA64, which is great for a $15 cooler.

I just bought a Cooler Master Seidon 120v v3 plus ( http://eu.coolermaster.com/en/cooling/cpu-liquid-cooling/seidon-120v-v3-plus/ ) and I am currently running it with only one cooler pushing out. I hear the pump running, I tried two types of thermal paste and double checked if it's placed properly. Idles at same 27-32 degrees, but reaches 80+ degrees under load from AIDA64 and EVEN THROTTLES after few minutes. The better side of the Seidon is that after I turn the stress test off, it drops the temperature back to 30 degrees immediately and keeps my case, along with all other components, much cooler.

I am taking into consideration that this is a CHEAP, AIO water cooling solution, but still... should it be outperformed by an air cooler of this caliber?!? I mean I am running the Hyper 101 with ONE 80mm FAN, set on silent mode?!? Maybe my new water cooler is malfunctioning? Or even worse, it's working as it should and I spent $60 on a useless piece of sh**.

Have you checked whether you have

a)  forgotten to take the protecting plastic foil of the cooler

or

b) there are capacitors on the board which interfere with the cooler

 

Otherwise you will have to return it, mayby it is broken or has to less fluid in it
