Ultra-Quiet 70mm Fans
70mm fans have never been a common choice of size for PC manufacturers and are found quite rarely. When they are used, in our experience they are usually found on CPU coolers and also on some more esoteric computer cases.
Right at the top of the range of fan designs, this DustPROOF 70mm Acoustifan is the last word in quality and quietness. It has the longest expected lifespan we have ever seen, and is extremely resilient to high temperatures, making it ideal even for use with hot-running CPU heatsinks.
We must stress that if your processor fan is starting to wear out and you are thinking of replacing it, you would be best advised to replace the whole cooler (i.e. fan plus attached heatsink), not just the fan. We have plenty of coolers for this purpose. The reasoning behind this is that a low-efficiency heatsink coupled with a fan which could have a lower airflow figure than the one it replaces may produce an increase in CPU temperature. However, for customers who do not wish to remove or replace the whole cooler, this 70mm fan will be an excellent direct replacement for any existing 70mm fan.
