The Noiseblocker NB-Multiframe M8-S3 80mm x 25mm Ultra Silent Fan is part of the family of Germany's quietest fans. The new Multiframe® technology uses silicone rubber corners to mount the fan, making it as quiet as possible. The NB-NanoSLI® bearing is also vital in providing the fan with its near silent performance and long lifespan that earns it a 6 Year warranty. Noiseblocker fans are the new standard in the industry of quiet computing!

Note: Fans come sleeved black. Please use the sleeving option below if you want us to change the sleeving to a different color.

I just installed two of these in my case and now I can only hear the slight sound of air being moved and that''s all. Great fans.

Last year, I purchased 70mm Evercool to replace an OEM Tai-Sol that came with the OEM P4 heatsink. The Evercool gave out within a year, so I looked for a Noiseblocker, but there aren''t any in 70mm, so I opted for this 80mm unit. It needed a 78-80 mm adapter (good thing FrozenCPU sells those), but it''s much quieter and much cooler also than any 70 mm fan that supplies adequate airflow. Worth the extra few dollars over a 70mm replacement, and the MTBF rating leaves me confident that it can handle cooling my processor fr a long time. The 140,000 hour MTBF equates to about 16 years, far longer than the old P4 will be around, but it''s great to know I can use it until windows XP is no longer supported.
