Scratch that. See mitigation measures on page 15. <snip> Although the R640 is designed for use in data centers, some users may prefer a quieter system.... </snip> -----Original Message----- From: Brent Kimberley Sent: Friday, March 8, 2019 1:09 PM To: '[email protected]' <[email protected]> Cc: [email protected] Subject: Re: [Linux-PowerEdge] T640 / T440 noise level comparison Any idea RE source? The 640 is supposed to be quieter. http://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/Dell-13G-PowerEdge-Acoustical-Performance-and-Dependencies.pdf https://downloads.dell.com/solutions/general-solution-resources/White%20Papers/Direct%20from%20Development%20-%20Dell%20EMC%2014G%20PowerEdge%20Acoustical%20Performance%20and%20Dependencies.pdf -----Original Message----- [EXTERNAL EMAIL] We have a few dozen T630/T620 servers and recently started purchasing the T640 models. I noticed that the T640 models exhaust noticeably more air through the rear than a similarly equipped T630/T620 sitting in the same rack (causing an increase in noise). I consider the T640 a quiet server, but they are not as quiet as the preceding generation and they are certainly not silent (nor would I expect them to be). I don't have any other Dell 14G servers around for comparison, but I would assume that these fan changes were made intentionally and across the board for the 14G server line so that the T430 -> T440 fan speed increase would be similar to the T630 -> T640 increase. I believe you can still purchase the 13G servers (minus some options that used to be available), if noise/volume is a priority in your application. --Blake Peter Holl wrote on 3/7/2019 7:41 AM: > Hello everyone: > > I have a T640 here and can't get it anywhere near to silent.
