[Review] Round 2: Enzotech Sapphire Rev.A and Luna Rev.A Tested

Preface
This is a quick version of my Enzotech Sapphire Rev.A and Luna Rev.A Testing....it's part six of my Roundup #2 of waterblock testing. The XS version has the boring parts cut out with basically just the core charts and the words :)

If you have any questions, check out the full review (link above)...if they're not answered, ask away here :)


Test Results

First up, individual mounts:

Both blocks have a definite orientation preference--the Sapphire Rev.A likes having its outlet to the top left (away from the GPU slots and RAM slots) while the Luna Rev.A prefers having its outlet at the top right (away from the GPU slots, close to the RAM slots).

• Very High Pumping Power: All three MCP355 pumps and the D5 are on at full speed--this has a very similar PQ curve to a pair of RD-30s at 20V.
• High Pumping Power: Two MCP355s with EK V2 tops are on at full speed. The other two pumps are off.
• Medium High Pumping Power: A single MCP355 with XSPC V3 top is on at full speed. The other three pumps are off.
• Medium Pumping Power: The stock D5 is on at full speed and setting 5. The other three pumps are off.
• Low Pumping Power: A single MCP355 with XSPC V3 top is on at minimum speed (~7.7V, ~2450RPM). The other three pumps are off.
• Very Low Pumping Power: The stock D5 is on at minimum speed--setting 1. The other three pumps are off.

Note: I do 5 mounts at "Medium High" then take the best config of a block and test the whole flow spectrum (after a TIM curing session) then realign that curve with average of the 3 median mounts to give you the "Adjusted" data.

Many More Graphs
I've included the core graphs and data here...but there's more in the full review, which is here.

Conclusion
Small tale of Jekyl and Hyde here, but I'll start simple. First, both deserve praise for their pricing and overall construction--the Sapphire Rev.A is ~$35 at Newegg and other etailers, while the Luna Rev.A is ~$45 at Newegg. The 1366 adapter is an additional $5, but that's not bad at all. The all copper construction of both is also a pleasant sight. Now let's split them up and consider them separately.

First, the Luna Rev.A is just bad. At every pumping power, it was the worst block I've tested (no single block was the worst prior to the Luna Rev.A). And it's really restrictive. I really feel little need to talk about the other points of it, without some signs of acceptable performance, there's little reason to consider this block when so many others out there are better.

The Sapphire Rev.A, all things considered, is a really good block. No, its performance isn't better than mid-pack, but considering how low restriction, how resilient to low flow it is, its all copper construction, and its $35 pricetag, this block is flat out good. The mounting system for LGA775 is really good, but the adapters for AM2/3 and LGA1366 are a little less stellar (but they are totally functional and superior to the piecemeal offerings of others). Simply put, the Sapphire Rev.A is a worthwhile block, especially to someone new to watercooling and not wanting to take an expensive plunge.
