Loud pumps

[hockey nut]

If you can.... pull off the fan cover and give the fan blades and area a clean as well as oil the fan drive shaft. 3 n 1 oil works well. It helped mine somewhat. The fans IMO are what cause it to be loud. I have taken the blades off and ran it like that for a few minutes and it was alot quieter but the pump heated up . I have mine sitting on some wood with no real vibration.

I love the pumps but are a bit louder than I expected.

HTH
