Welcome to the 7th block in my series of i7 – 2600K CPU block tests. You may be familiar with the extremely popular XSPC Rasa that many users enjoy in the popular kits, it is an excellent block possibly one of the most popular due to the exceptional value it provides giving top 2011 generation block performance levels. XSPC has spent many months building basically an all new block called the Raystorm!
A special thanks to Paul from XSPC for sponsoring this test! They provided the tested production sample prior to these blocks hitting the shelves, but I believe you should be seeing these next month at retailers.
Highlights
First let’s go over a few basic highlights and characteristics.
- High Performance Copper Base 56mm x 56mm x 3mm deep
- Microchannel & Nozzle Plate Design
- CNC Cut Acetal Top
- Intel kit supports sockets LGA775, 1156, 1155, 1366, and 2011 and comes with back-plates
- Full Cover Back-plates for more MB protection, and easy peel and stick type mounting.

- G1/4 threaded wide ports are compatible with most fittings include 3/4″OD compression fittings

Update 2-9-12
Working on the copper top version, similar design, but instead it has an aluminum hold down and solid copper top.

Brilliant review, Martin! I appreciate the practical perspective on running low pump speeds.
Hi, Martin!
What do you think about the new total copper edition? *_*
I have one, need to get an update posted with pictures. It’s really nice and very well constructed…always liked the all metal construction blocks…:)

just ordered the copper version instead of the black – only to stumble across this thread/review showing it has higher restriction than the acetal top… :/
