I found this on the web last night and i found it VERY interesting ! It's interesting that a less powerful TEC can cool better than a more powerful one, though there isn't much difference in TEC Qmax.. I assume the gain has come from the cooling being more concentrated on the less powerful TEC and therefore making it more efficient at cooling a small CPU Less heat spreading required. I also find the results to be surprisingly good!They did power the 340 watt TEC @ 48 volts not the rated 32. Which is strange, in saying that it's unlikely the PSU would be putting out 48 volts as 48 volts would have FAR exceeded the 600 watts of the PSU leading to lower voltages.

The new 340 watt 50mm x 50mm peltier module has been received and tested by the Arctic Spider staff. The new peltier was tested on a Danger Den Maze-4 block and a Wintsch Labs Arctic Web, and the results were eye-opening.

The graph above shows the results of the test. The test rig was a Intel QX6700 running at stock speeds on an EVGA 680i motherboard with 2 gigabytes of Corsair PC-6400 RAM, an EVGA 8800GTS video card, Thermaltake Toughpower 850W power supply and standard peripherals. The Meanwell PSP-600-48 power supply was used with the 340W peltier, and the Meanwell SE-600-24 power supply was used with the 437W peltier.

The water loop consisted of 2 Black Ice GTX 120.3 radiators with 3 Panaflow high-speed fans each, Danger Den DD12V-D5 Variable Speed pump set on "5", EK Water Blocks reservoir, and 1/2" tubing throughout.

Two tests were run with the new 50mm 340W peltier module. One test was run on a dirty Danger Den Maze-4 water block we had lying around, and another was done on an Arctic Web. For comparison, a third test using the same setup was performed using the Arctic Web and a 437W (360W, really) 62mm peltier.

All three tests were performed using Prime95 to stress all four cores. All three lines in the graph represent the temperatures achieved during the 24 hour duration the test was run. The top line represents the temperatures achieved by the 340W peltier on the Maze-4, the middle line represents the 437W peltier on the Arctic Web, and the lowest line represents the 340W peltier on the Arctic Web. For this test, lower temperatures are best.

As you can see, the results are quite suprising. The new peltier allows users to use older style TEC water blocks that support 50mm x 50mm peltiers to cool quad-core processors. This used to only be achieveable by the 437W peltier on an Arctic Web. Putting the new peltier on the Arctic Web will outperform the current Arctic Web set ups.
