Cooler Master Eisberg 240L Prestige Liquid CPU Cooler Review
Ryan Martin+ / 9 months ago
At stock we saw only a marginal improvement over the smaller Eisberg 120L. The Eisberg 240L also is a fair bit behind the 280mm AIOs but retains competitive distance to the Swiftech H220 and Corsair H100i.
The acoustics were marginally louder than the Eisberg 120L Prestige as the two fans were pushing and pushing fans tend to be a bit louder.
Overclocking saw competent results. I am actually slightly worried and how little difference there was between the Eisberg 120L at 5 volts although the gap did grow as we tested the Eisberg 240L at 7 and 12 volts. Still I was slightly underwhelmed by the performance of the unit. Given how large and powerful the pump is, I expected more. I opted for some Noctua NF-F12s to see if the fans were holding the Eisberg 240L back, and not surprisingly they were but not by that much – only about 1 degree.
The difference between the Swiftech H220 and Eisberg 240L is about 1 degree at equivalent volt levels. I think the reason why the Swiftech H220 wins is just purely because it has better quality fans, not to mention the fact they are PWM and a lot quieter too. The 280mm Asetek based Corsair H110 and NZXT Kraken X60 are both worth honourable mentions here. Both units performed better and clearly the extra surface area does make a difference. Also the Corsair H100i has held its ground well too, no doubt thanks to the excellent quality of the SP120 fans Corsair use.
Acoustics were pretty load above 7 volts and this is mainly due to the pump getting hugely noisy at higher RPMs. Though swapping the fans out did make a difference and the Noctua NF-F12s produced less noise and better temperatures compared to the stock Cooler Master fans.
