Saved the top x16 Gen 3 PCIe Slot by rotating Noctua NH D-15, but will these fans sound OK at low rpm?

Well that was really tight 3 mm to spare, OK it fits vertically, just :-/ , and saves me sacrificing the top x16 Gen 3 PCIe Slot - :) very pleased about that, as I only have 3 on the SM X10SRA.

Really appreciate advice from anyone who knows fans - will the roof fans close proximity cause turbulence or weird noises. likewise being ofset ( deliberately to bring in the second fans extraxtion power.
As you can see to mess withthe the fan locations would mean taking out the cooler :(

The only other way is to loose the roof fan above the coolet exhaust fan, move the other one over to the right.
And then put the removed 140mm to the outside rear of the case, sort of in line with the rear wall exhaust.

Still got to make the Bracket to take the last 120mm front intake. Think I Can do it with a bracket extending the 120mm fan rail at the front by about 60mm. Not reslly needed I hope but required to deliver anti-dust positive case pressure.

Maybe this will be a total failure but I hope just rinning at 500rpm hopefully will keep things pretty cool. And therefore very quiet.

Yes I wanted to have the cooler blowing from front to back ie horizontal and then all air flows are front to back.l
But if it whent that way then I lose my top x16 gen 3 PCIe slot:(
Noctua say it can go either way.
So tried this and it worked.

Actually I must check if the base plate on the noctua is toyally square, as xeons are slightly rectangular.

Anyhow going vertical means I get the extra all important slot.
I am hoping 2x 140mm in and 1x 120mm in - and 3x 140mm exhausting plus the Coolers 2x 150mm will still keep it really cool.

Interesting, I got the D-15 as the TDP is 140 W on the E51650v3, I did notice there were a lot of cooler running Xeons, such as the E52620 v3 with a TDP of 85W.
Most of the E3... V5 are 80w.
But good to know as I will not be overclocking it.

Do you find any difference exhausting vertically - is it as efficient?
And was that witha Xeon cpu?

My e3 1231V3 is 80w. And you may try use one fan to see what temp you will get.
Sorry I don't try your method for the cooling, but I guess there is not big difference between those. Maybe in future when I clean up my pc, and try that way.

Room Temp. I know the maxi temp =66.7C http://ark.intel.com/products/82765/Intel-Xeon-Processor-E5-1650-v3-15M-Cache-3_50-GHz
Where do you get those 42C to 50C reading ? From the inside the BIOS or from the software? If it is from the software you may try update the BIOS, because the sensors need newer BIOS. But if it is from the BIOS, it may relate to the BIOS setting or other source, like oc by BCLK, or the voltage ( high voltage will cause to high temp), etc.

I got the 42-50C readings from the Bios, and thats also where I got the 1.472V reading from.

Guess I am a bit stuffed if a new Bios cures the over-voltage, and the CPU then works under 1.3V but has been damaged to some extent by running it at 1.47V i.e. 0.17V too many for say 10 hours total. [ maybe an hour 30 mins at a time as I tried to solve the PCIe SSD boot difficulty ].
Just my luck it gives yp the ghost in 18 months or so. Not exactly in line with my plan of buying enduring hardware used to 24x7 !
Maybe that would compromise my CPUs longevity.

Thanks. Well peed off with Supermicro. They certify this board for the E5 1650 V3 and then ship it with an ancient bios, that over voltages the CPU.
Nice! as Intel would not ( quite justifiably ) want to know about damage caused by a 3rd Party's crap Bios. :(:(

And there is no way to manually turn down this voltage in this version of the Bios. The superuser button is deactivated. They "think ???" there may be a way to do it in the later Bios. Or the later Bios may solve it. A bit too late as its been running at 1.47 Vs :(
But apparently I now need to create a "Bootable USB stick" - wtf is that! And they sent me a link on how to do it and this takes me to a Window Millennium zip file!!!

Beginning to wish I had just bought an HP Z640! No Hassle just plug it in and bingo!
