Need some expertise here =P

I've been thinking about getting water cooling, however I don't understand what's the difference between these two CPU blocks

Watercool HEATKILLER CPU Rev3.0 1156 LT

and

Watercool HEATKILLER CPU Rev3.0 1156

I mean, other than the some of the specifications and colour, what's the difference? I personally want to go for the black one, but i don't want to compromise performance just for aesthetics.

And are there any dealers in Vancouver? ... I don't want to pay the brokerage fee like i did for my power adapter... 20 bucks for a 40 dollar product... freakin ridiculous. And is there anything I should look at when i look for components? Like barbs... um.. tubing... all those things... could someone educate me =)

TY!

The quality of components of the non LT is a little higher, in addition to better materials, has more bling factor. Looks like the LT has a less pure copper material, and steel. As opposed to stainless steel and "high-purity copper" of the non LT.

The CU has a Copper top and the LT has a POM Acetal top. Both have the same internal components, Copper baseplate, mounting hardware, etc. Other than the tops, there are no other differences, including no differences in cooling ability!

BTW, over time that Copper top tarnishes and discolors from fingerprints, etc. It gets really ugly. I know because I have one. So when I recently switched to an EK Supreme HF, I went for the POM Acetal version.

Also, I think the differences between blocks are way overblown. The Heatkiller 3.0 and the EK Supreme HF both seem to cool exactly the same to me.

You should probably just buy whatever suits your fancy.

The biggest difference is the LT is uses POM (plastic/acrylic) making it lighter, 150g vs 400g for the pure copper version. The other thing with the POM is the G1/4 threads can strip easier than the all copper block making it not as durable in the long run. The performance will be a little better with pure copper version although I doubt it be a huge difference, and the bling factor does count for some users. Barbs and tubing come in various sizes, most common are 3/8" and 1/2", 3/8 is easier to work with in tight spaces and there really isn't alot of flow difference between 3/8 and 1/2", just make sure you choose the same size for your pump (MCP 355 for 3/8 or MCP 655 for 1/2")

As for brokerage fees, if you ask them to ship by ground U.S. Postal Service you won't pay any fees for orders under $100, it may take a few days longer to get there but you'll save some coin.

As said above, LT = acetel top, normal = copper. You may see 1/2C change at MOST.

I would recommend an EK Supreme HF however, less restrictive, cheaper, and cools better.

Yes. I can confirm what others have said.
Based on the review from martin's or skinee's WC lab. the difference is small.

IMHO Acetal version of HK is not worth its money, but copper does.
