Antec Kuhler H20 H1200 Pro & H600 Pro AIO Review

Performance

Stock performance on both coolers is certainly impressive, beating out far more coolers than I was expecting for coolers in this price range. Ignore the glitch on the 600’s idle temps, it was 1, but my charts are playing up. However, 22c delta and 20c delta for the 600 and 1200 respectively is absolutely amazing.

Even when overclocked, both coolers put up a commendable score, with the 1200  doing rather well especially. Sure these scores aren’t as good as some of the other similar specification coolers on this chart, but when you consider the build quality and price of these units, it’s hard not to be impressed.

Another superb result here, both coolers were whisper quiet and the 600 was barely audible from a range of 1-2ft. The pump noise is virtually none existent, with only a mild bubble sound for the first few minutes of operation to be heard when you hold your ear close.

Again, even when overclocked we see great results from both coolers. The fan noise is very low and the pumps are still virtually silent. The fans on the 1200 didn’t even speed up when overclocking, although the 600 had to work a little harder it was still very quiet overall.
