TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
We were not expecting the Arctic Cooling Freezer 7 LP to break any records, and the performance is just about what we expected. Direct competitors to the 7 LP are the Thermolab coolers, and the four Glacialtach coolers.
80mm fans are prone to being a little louder than 92 and 120mm fans since they have to spin faster to move the same amount of air as larger fans. Spinning faster produces more noise, but the 7 LP has a max speed of only 2000 RPMs. The Arctic Cooling Freezer 7 LP wasn't as loud as some of the other small coolers we have tested, but at full speed it is a little louder than we expected. Granted, it will be a rare occasion when the cooler would turn to full speed (via PWM) but if it should happen, you will hear it outside of the case up to two feet away.
