Conclusion
While the Raystorm Acetal was and still is a top performing block on the 2600K, it’s always nice to have metal top options that perform equally or better while being that much more durable in materials. The copper top Raystorm improves many of the few things that I would have liked to see the acetal top be although there are a few very minor things to improve on the mounting system, namely some sort of means to mount with the fixed pressure.
Pros
- #1 (tied) in thermal performance in 3930K testing so far.
- Very low restriction
- Durable all metal construction without plating for extreme durability
- 1155 Users Easy mount back plate
- Full coverage back plate provides ample MB support and protection
- Very complete package, everything except barbs & clamps included
- Wide barb spacing compatible with most G1/4 fittings including 3/4″ OD compression fittings
Cons
- Loose parts mounting system without mounting force guidance. Very stiff springs don’t provide any sort of force guidance.
- Cost – Higher than average CPU block costs, some places are >$100
There you have it, the Copper Top Raystorm was happy to cool the very hot 3930K hexacore in all it’s copper top styling..:)

I see that you haven’t reviewed the Koolance 380I block yet. Would you mind telling me if you agree with this data I found here: http://hardforum.com/showthread.php?t=1708036&page=4
I’m trying to figure out if this data still applies today and the 380I is still the best block. Thanks!
While there will always be some differences between reviews due to block sample and processor shape variances. That is extremely good testing so yes I would trust it. I would have to start over if i wanted to do cpu block testing since I moved and rebuilt my rig.
