Hi
I have just bought a 2nd hand R815 but am having major issues with the noise levels. It basically is far too noisy and constantly sounds like a jet taking off. I have 2 other R815 with more or less identical build specs (Same RAM and CPU's) and they are fairly quiet in comparison.
The R815 in question almost has like a pulsing feel if you touch the chasis (going down the chasis if that makes sense!) and sounds like it is vibrating inside in some way. I have tried to swap fans as well as the entire fan assembly with one from one of the other R815s that is working fine and this makes no difference to the noise. I have also changed the fan settings in the BIOS from maximum performance to minimum to avail. I have also thoroughly checked the inside for loose cabling etc and everything seems fine. The server is working perfectly fine in every way apart from this but the noise is simply unbearable.
If anyone has any help or suggestions it would be greatly appreciated.
