Purchasing a Precision T7920
Hi Guys, I currently own a Precison T7910 running Dual Processor Intel(R) Xeon(R) CPU E5-2697 v4 @ 2.30GHz, 2301 Mhz, 18 Core(s), 36 Logical Processor(s) and CPU fan noise can be annoying on normal load.
So now looking to purchase the T7920, my question is, what dual CPU configuration with high performance will run quiet on adverage?

Hello,
a small note to put at the beginning... I have a 7820, not a 7920. This said, it's quite quiet with 2 x silver at 85w each. I think that if you go with a 7920 with 2 x 4216 ( 16c/32t 2.10ghz to 3.2ghz turbo , 100W each ), it should be reasonably quiet. The Gold 6226R offers the same number of cores with higher base and turbo speeds, but at 150W each, i'm not sure about the sound. Again, this whole is a speculation.

@mazzinia_ Thanks for that, so the lower the TDP the quieter the Processor fan? I was thinking the Gold 5120, 105W

@claytonb basically yes, at least at full power. at low load or average load, the fans will likely spin at the same speed

Just want to point out the result may vary as there are architectural differences between the two models.
In the 7820, the CPU are stacked, top and bottom, separated by a CPU expansion riser board. Creating separate chambers for airflow.
While in the 7920. both of the CPU are in-line, front to back designs. One CPU would sent heated air to the second CPU within the same airflow chamber. Resulting in higher demands of airflow (fan noise) for CPU cooling.

@Chino de Oro Thanks for the info, I have decided to keep the T7910 as I have a couple of 16TB SAS drives, I do have the raidiator fans and vented side panel installed for better cooling.
I'm going to try a couple of Intel® Xeon® Processor E5-2660 v4, 2.00 GHz @ 105 W.
Hopefully that should tame the fans
