    Thoughts on Optimal Case Fan Placement

    Posted: 06 Dec 2020 01:51 AM PST

    Please keep in mind that i'm not a native speaker. But until a few years ago I worked for Airbus, simulating their temperature regulation and environmental control system.

    I'm just now building a new pc (got my 3070 yesterday) and I searched for some sources regarding optimal placement of case fans. Of course its always easier to get low temperatures with more fans, but then you also have more noise. You can regulate down fan speed to compensate for noise, but there might still be fan configurations that are inherently more efficient than others.

    Most guides treat the following config as a kind of baseline: 1 fan in the front, 1 fan in the back. I am not convinced. And here is why:

    1 Front + 1 Back: The fan at the front has to overcome the pneumatic resistance of the case inlet mesh. Thats why static pressure optimized fans are recommended for front fans. On the back of the case, there is no fine mesh, but larger holes. The back fan drives out the air through this larger holes. Here, an air flow optimized fan could be used because resistance is smaller, but since you don't want underpressure inside the case because of dust reasons, you cannot utilize the larger air mass flow of the back fan. Lets say with this setup we have an air mass flow of 1.

    1 Front: The front fan works like before. The back fan is gone. What happens to all the air that is inlet by the front fan? It has to go somewhere. The front fan will create a slight overpressure in the order of a few pascals, this will drive out air through all the remaining openings of the case. So mostly the position of the nonexisting back fan, where the holes are largest. This will not even burden the front fan that much, because the additional resistance to overcome is small compared to that of the front mesh. Lets say with this setup we have an air mass flow of 0.8.

    2 Front: Now we are using the saved back fan in the front instead. They are using different parts of the mesh, so their inlet resistance is independent of each other. They are sharing outlet resistance, so that one goes up. But it should still be small compared to the fine mesh at the front. Lets say with this setup we have an air mass flow of 1.4.

    So my prediction is that putting all fans to work at the side of the largest resistance (the inlet) you can increase total air mass flow for the same amount of total fans used.

    Another benefit could be, that if you completely fill out the front inlet with fans, all inside components will directly get blown on, so less of a risk of stagnant air pockets inside the case.

    Has anyone ever tried this? I see lots of comparison videos on youtube, but there is always one exhaust present.

    Short performance tests (on OmniOS/ESXi): Intel Xeon Silver 4110 vs AMD EPYC 7302 / Disk vs Flash vs Optane / barebones vs. virtualized

    Posted: 05 Dec 2020 09:25 AM PST

    Napp-It's developer just posted these benchmarks (PDF warning). Per his comment on the Illumos mailing list:

    The Epyc system was up to twice as fast as the Xeon system with same pool with encryption and without.

    I copied the following from the PDF for context:

    This benchmark sequence was intended to answer some basic questions about how the new Epyc platform performs vs an Intel Xeon silver on a disk pool vs Optane/Flash pool. Additionally we check encryption performance and OmniOS 151036 vs 151036 with FPU accelerated raid-Z.

    All tests are done via a filebench run that checks random io vs sequential io with sync and enc on/off and barebone vs virtualised in napp-it menu Pools > Benchmark. Intent is to get a feeling about behaviours.

    Intel Hardware:

    • SuperMicro X11SPH-NCTF, Xeon Silver 4110, 64 GB RAM, SAS 3008
    • 7 x WD Ultrastar 8TB, 3 x Optane 900, 3 x Intel DC 750 (traditional Flash NVMe)

    AMD Hardware:

    • SuperMicro H12SSL-C, Epyc 7302 128 GB RAM, SAS 3008 (BTO system)
    • 7 x WD Ultrastar 8TB, 3 x Optane 900, 3 x Intel DC 750 (traditional Flash NVMe)
