I would suggest that the first thing to do is by hearing protectors. Wink

Haha, well we have the replacement fans ready to install. And these will be in a server room kept nice and chilly.

We will be selling off some of our B7 / B8 S3+ units to free up some PSUs.

Perfect condition, housed in Server Room at 64 F (approx) Hepa Air Handler. Clean and Like New.

I apologize if this is off topic but if there is any interest just shoot me a PM.

I am curious though. If these are in a server room, why tinker with the fans at all? Is there a noise concern in the room? I thought the issue with the S5 fan was strictly noise related.

The server room does have a high noise floor to begin with. But I was concerned these might be over the top db wise.

Also from what I have noticed with servers is that noise affects the performance of reading from and writing to the mechanical hard drives (SSD's are obviously unaffected by noise vibration as they have no moving parts). The noisier the environment, the slower they get.

BTW, is anyone able to compare the noise to an S4 please? I have an S4 and had to find another location for it. I had my neighbour knocking on my door asking what the hell the noise was and saying that he could not sleep with it (we both are in separate houses and his bedroom is about 50 meters away from my house). I have seen reports of the S4 between 70 and 90 db but not sure how accurate they were. It would be great if someone could do a test using the same metering device at the same distances for testing both.

Interesting Ive never heard that. All system critical drives were upgraded to SSD long ago. The only spinning drives left would be the large raid units, but they're housed in 8 FT Rack Cabinets, and the drives are all enterprise grade.

But yea SSDs are the way to go. I recently upgraded my workstation RAID to 16 Crucial 960 GB SSDs in two groups of 8, each on RAID 0. Im getting 5.50 GB/s read write performance between the two, and 2 GB/s transfers on our 10GBe Dual Network Cards.

Amazing how fast things have gotten.

I know this seems off topic, but just responding to your comments on drives... And thinking how in terms of speed and how fast the technology is getting... Bitcoin seems to be the lone ranger going in the opposite direction.

But perhaps thats the point.
