When it comes to watercooling the Eheim and Hydor pumps have been the leading ones on the market. Swiftech and Dangerden both have released their own pumps and today we take a look at a 12V pump from Dangerden that we just received for testing. The problem before with 12v pumps have been that they make quite a bit of noise. Performance wise they have been pretty equal to the bigger 220V pumps but as said noise wise they are louder. That is exactly what we will be concentrating our review on today to see how loud it is and what performance we can get out of this pump.
