@Landmine

Tried it on another 1U server I have and it works well. Just keep an eye on the temp and make sure the room or space it’s in is well ventilated.

I have a couple of U1 servers in my home office that I need to make silent. I’m going to try Manny’s idea and see if that helps.

Anyone else have any other ideas that work?

@Fritz

Explain to me how that’s a possibility when the CPU is running well within the temperature specs of the processor?

Oh, and posting the same exact comment once is all that’s needed.

Soon of later, the CPU is going to burn the motherboard. You need to bring the temperature down a bit lower.
I am having the same noisy problems with two 1U Supermicro severs installed in my living room.
Here is another stupid ideas. Make hole in the top cover the size of the a larger quiet fan. Put the larger quiet fan sitting on top of the hole with the server cover on. Now you can shutdown the noisy fan and problem solved. I don’t have a picture to show you but it works.

@Brad

I actually followed Manny’s advice and did the same… works great!

@Manny
I have the same Rackable systems 1U server as you guys do, and I chose to follow Manny’s technique. The fans still run at a decent amount, being 13,000rpm 40mm fans at full 12v, and the noise level is VERY MUCH reduced. I could hear this thing through the entire house, now I can barely hear it in the same room.

@Manny

Sorry for the delay in replying – I was on vacation…

That’s a good idea… my method works out because I am using a secondary hard (not pictured) drive that does not fit in the case with the cover on but I like your method too.

I have the same Rackable systems 1U server. All I did was reverse the red 5v lead and the yellow 12v lead on the power plug that goes to the fan backplane unit. it runs the fan unit 60% less. Less power to push the fans. They run quiet now. With the cover on. The CPU’s run 34 to 39 degrees celcius. quiet machine now and it’s awesome. Hope this helps.

@Robert

Even just *one* of the small rack fans is too loud.

What about, you know, unplugging only a couple of the fans? I have a similar 1U server, and it’s loud! I might try this.
