content: Quote from: tautech on March 02, 2023, 11:28:42 pmDoing noise level would have been a good idea, but the old fan had already died. Frankly, I think the new fan is only slightly quieter based on qualitative listening.Of course the Noctua connector was different, so I had to cut the connector off of the old fan and solder on to the new fan. Noctua provides rubber mounts. I should have used them...prolly would have made a difference. Maybe I will tear it down and try.Getting into the scope is very straightforward...an easy repair.

content: Quote from: Wimberleytech on March 08, 2023, 02:18:58 pmThis seems to be the norm in that the OEM fans are not too bad and there's little to be gained from installing any similar spec fan.QuoteAs mentioned in another thread I cut the metal fan grille from my SDS1104X-E which barely made any appreciable difference which indicates mounting mods could be of better noise reduction assistance.Please report if you find such.QuoteNever been inside a 2000X-E however as the case format is same used in the 2ch 1000X-E it should be easy peasy.P36https://int.siglent.com/u_file/download/22_08_23/SDS2000X-E%20Service%20Manual_E01A.pdf
