PowerColor LCS HD6970 Review


Back when we first got our hands on the HD6970 from AMD we found it to be a good performing card, but intolerably noisy and hot. To be one or the other is not good, but acceptable. To be both isn't so fancy.

Of course there are two major ways to be cool and quiet. Either have a third-party cooler with a much better design and array of fans or, as is the case here, put the whole thing into a watercooled loop.

Watercooling has moved a long way from the early days and with non-conductive liquids and much higher quality fittings it's no longer the scary upgrade it once was. The major problem is the voiding of your warranty should you choose to fit a waterblock to your graphics card.

PowerColor have helpfully got around those problems by fitting a full-cover EK water-block to their HD6970 to give us the LCS HD6970 and that's what we're taking a look at today.

Technical Specifications

Beneath that Acetal top beats a standard HD6970 overclocked just shy of the 940MHz that we find on the PowerColor PCS+. If there is one thing that the watercooling should ensure it's much greater overclocking headroom than we saw on the PCS+.

I must admit i'm impressed. After the first review of the 6970 with an air cooler the 6970 seemed pointless but this version is definietly worth the money especially after looking at the performance results.

Always liked the look of this. Watercooling without the warranty voiding.

Hope you get to do a review of the 6990 version when its released.Quote

Yeah just tweaking my xfx 6970 that I put a xspc razor block on a few days ago. Sitting at 950mhz and 1425 on the ram amazing what watercooling can do. This card running heaven never breaches 53 Degrees. That's in loop with one 360 rad and a 950 cpu @ 4.0 ghz.Quote
