I agree, EK designed there block to be compatible with reference designs which most likely included the shorter cap. If the cap heights aren't included in the reference design specifications, then AMD needs to start being a little more detailed and in this case it's not AIB's or EK's fault. If cap heights are included in AMD's specifications, then the AIB's are at fault now.

If EK had to wait for every AIB to release all their reference designs and revisions, we wouldn't see a waterblock for a while.

The fact that EK did acknowledge the issue and present the problem is quite good on them in my opinion.

As my signature says please use EK Support mail regarding all questions.
Thank you,

EDIT: typo

No, my original question and entire thread (which I linked) was about the PCB looking/seeming different from reference (when it was being sold under a reference model number) and being concerned about fitting an EK block to it. But regardless, thanks for your help.

Save money? Supply? Or, and this is assuming that the squeal people are complaining about is coming from the capacitors and not something else, to help reduce the squeal perhaps? These are just guesses, of course. But I do know my PowerColor 7970 doesn't have much squeal under load, like many other 7970 users are complaining about, but this could just be luck. In short, it could be for many reasons and we can only guess as to why.

The squeal is not the caps, but the coils(or just the inductors themselves) in the inductors hence coil whine.

Squeal comes from inductor coils. Try clocking the 7970 card past 1.4V and 1450MHz and you will soon hear what the real squeal is. Still this has nothing on my old X1950XT... Whole symphonic orchestra on a single PCB. rolleyes.gif

thankfully I haven't had my cards squeal yet. and hopefully I don't.

Just contacted Koolance, their blocks are not affected by this raised capacitor. They responded to my inquiry (email) in less than 1 hour!

Some more info for people affected: The the revised EK tops aren't listed on their site, and if you contact EK support they are going to wait an entire business day to have someone tell you to buy another complete block, even when you only asked about buying the top (which is what the article about the taller cap says to do...). specool.gif
