Watercool 7970 lightning without a full-cover block - Page 2

post #11 of 18

MSI changed the design of their 7970 Lightning PCB randomly without informing us. Older 7970 Lightnings use our blocks perfectly, newer ones for whatever reason die. Which is why we have discontinued the block, apologies for the inconvenience.

I still haven't installed the block, how do I know if my lightning is older version or not? I sent you guys email before buying the block, asking if it was safe to install;

"The waterblock is safe to install, if you do everything by the manual you should not have any problems.

Thank you for understanding.

If you need any further information, please do not hesitate to contact me.

Kind regards P**** Š***"

Boost edition lightning, if it matters.

To the OP, get a Swiftech MCW82, and one of these and you'll be set.

I ordered mine from there few months ago, ended up costing 190€.. rolleyes.gif

That sounds good,smile.gif but what about the problems some people having with this block shorting out the cards, is there any solution?

Do you now for sure that the heatsink is compatible with the lightning?

EDIT: I just saw the compatibility list and lightning is not compatible with that heatsink mad.gif

You do want to at least have airflow around the VRM heatsinks.

Aquacomputer blocks on the 680 Lightnings that replaced them are PERFECT in every way, and build quality makes the EK blocks feel like toys.

I'd look into the Heatkiller VRM waterblock for GPU's; it may actually work with the Lightnings!

I'd forgotten that, a few people killed 7970 Lightnings putting those EK blocks on...

From what you know is there any fix i could apply before installing the block to the card? For example put an extra thermal pad somewhere or some high temperature insulating tape?

All I can say is that I lost both my R7970 Lightning's to EK blocks, and while I'm sure that it is a rare occurrence, I'm not the only person it's happened to. Fortunately, MSI replaced them with 680 Lightning's (and my God, the Aquacomputer 680 Lightning blocks are B-E-A-UTIFUL!), but I've been wary of the EK blocks ever since.. It's hard, too, as I really, really want to support them as they're located in my family's home town :/
