InterCosmos.com heeft een vergelijkings artikel online gezet over de zgn. 'software coolers'. De deelnemers zijn AmnHLT 2.1, CPUIdle 5.6, Waterfall Pro 2.99 en Rain 1.0. De laatstgenoemde wint met een neuslengte:
All software coolers really cool your processors so you should have no doubt about it. CPUIdle and Rain have tie in that aspect by cooling the most out of your CPU. It seems that all software coolers do not affect the CPU performance as shown in the benchmarks. Only CPUIdle and Waterfall Pro show a little dip in graphics performance while AmnHLT and Rain do not seems to have any impact at all. It is tough to pick the winner as each has its own strengths and weaknesses. Personally i would pick Rain 1.0 as the best software cooler due the fact that it is very simple and easy to use and also it is a freeware and it doesn't affect CPU performance at all. I would recommend you choose the programs that best suits you; if you go for feature packed programs then you may consider CPUIdle 5.6 or Waterfall Pro 2.99.
