Block decision

post #1 of 27
Thread Starter 
I recently sent my EK Supreme HF Full Nickel back because of the Nickel flaking reports going around.
Lucky for me I hadn´t used the block yet so I got a full refund.


Now I am struggling to decide what block I will get instead.

I need a Nickel block with good flow and great thermal performance.
Also the fabrication value should be good and the block should have the possibility of a 1155 Sandybridge mount
.

Those are the blocks I had in mind:

1.)Kryos XT
2.)Koolance 370
3.)Apogee XT rev.2


a.)The Kryos XT is said to be very restrictive ...I will take Vapor´s review of it for example.I had the block once already and did not experience the low flowrate results that were shown in the review.
I think the reason for that is because multiple flowmeters were used that reduced the overall flowrate of the loop and therefor the block´s as well.
According to a friends results of the Kryos the block has 1.5 GPM at medium pump setting and 1.8PSI of pressure drop at 1 GPM.

This block has the best thermal performance and the Nickel plating appears and is confirmed to be solid by Aquacomputer employees.
Also 1155 mounting is possible and it looks great
With the Fabrication and Outer quality of the block I unfortunetly made a bad experience though so -1 on that.


b.)The Koolance 370 is in my oppinion the most beautiful of all the blocks listed with the best fabrication value and quality.

I am not sure of the performance but according to Skinnee´s test it should be about 1 degree worse than the EK Supreme HF.
And have 0.07 GPM lower flow than the EK.

I would love to get this block ...but I am not sure of it´s performance so I hope you can give me som clearification on that.
If it just were 1 degree difference it would not matter because I am running a 1080 rad which would compensate this marginal difference easily.
Flowrate is important because my loop is kind of restrictive so if it also only were 0.07 GPM worse than the EK that would be my block.
Just need some confirmation on that besides Skinnee´s test.

c.)Apogee XT rev.2

This is the flow enhanced version of the normal Apogee XT.
Swiftech states that the block will not have any cooling ability loos due to the flow upgrade.
That is why I will assume this block performs on the same level as the normal Apogee XT.
According to the charts this block only has 1 PSI of pressure drop at 1 GPM which is even better than the EK Supreme HF so judging by that it is great.
But the thermal performance of the Apogee XT is I believe worse than 1 degree compared to the EK Supreme HF and unlike the Koolance 370.
Other than that the block has great fabric and quality value , but too little Nickel on it for my taste.


People I am really struggling to decide which one to take ....
I hope you can help me out and add your oppinions!!

thx in advance

My opinion:
I would have kept the EK block.

And Sandy Bridge is 1155, not 1556. You probably just made a typo, but just incase.

Discard the Kyros if you want appearances and high flow. It's hideous and extremely restrictive.

I'd get the Apogee or an EK Supreme HF (IK it's not included, just sayin') if you want nice flows and nice appearances. The EK is probably the best spent money on a cooling product I've ever bought.

I just keep hearing wonders fom the Apogee XT, so that one gets my vote too. But the Supreme HF above any block imho. Worth every cent I spent on it.

The EK Supreme HF Full Nickel especially the rev.2 has had over 100 documented and executed RMA´s over the past weeks.
This block has a very low quality Nickel Plating which obviously was intentionally applied by EK even though being aware of it due to a random block inspection.

I will never ever touch an EK product again in my life.


So the questions comes down to Apogee XT rev.2 vs Koolance 370

The better flowrate clearly goes to the Apogee XT rev.2
But I think the Koolance beats it in cooling performance ,looks and quality value.

What do you think guys?

If the koolance 370 is really only inferior to for example the Kryos XT and EK Supreme HF in cooling performance by 1 degree I would not care.
Because that degree would be negated by my 1080 rad....I just need some more confirmation on the 370´s performance.

Do you have any proof or information?
I hadn't hear of any 100 documented RMAs of this block being returned.
I have it. Works great, no nickel issues.


And regarding a replacement, so far the 370 is considered the best if you ignore the EK one.
Skinnee did a review for it. Came up pretty great.

In Austria a lot of people have reported their cases.
I am not sure if it were exactly 100 but at least in the 90 zone.

Yeah the Koolance 370 looked was great.
Could you maybe compare the flow and thermal results to the other top blocks including the Apogee XT rev.2?

Sorry but I'm still skeptic about the 100 or 90. Need more proof than how you feel or what you heard.

And for compares, as I don't have any of them, I suggest you go to skinneelabs.com and read some reviews. He has a comparison between the 370 and the EK full nickel.

So because of one bad product that you never actually experienced the problem with yourself, you're never going to buy a product from them again in your WHOLE life? Isn't that going a bit off the deep end (overreacting a bit much)?

If it was just a bunch of faulty blocks , no.

But Nickel GPU Block from EK, Supreme HF Full Nickel, Nickel/Acetal etc....
Multiple RMA, complaints, rejected RMA proposals with following accusations of self inflicted damage to the block due to unintended use of substances and materials.

And on top of all that , they will not even admit that the faulty and low quality plating is the cause of this.


That is why I will never touch an EK Waterblock again!


----------------------------------------------------------------------------------

But please back to topic Koolance 370 flow and thermal performance comparsions to all the top blocks including the Apogee XT rev.2?

I apologise if this has been suggested but why not get the Full Copper version of the EK Supreme HF?
