humidity, before running an instance of
Prime95 for an hour, and noting down
the max CPU temperature. We’ll then let
the system idle for 30 minutes, before
performing a Fire Strike “Combined”
loop test for an hour, noting the max GPUtemperature. We’ll then use a phone app to
measure dB(A) during 50% system fan RPM
under load in an empty room from three
feet away. Including temperature deltas
against ambient for both components will
account for fluctuation in ambient heat.MOTHERBOARD BENCHMARKSCASE BENCHMARKSProduct Name Product NameCinebench R20 Single/Multi (Index) 00 / 00 00/00

From there we move into some real-
world testing, again throwing in a run
of our now-staple Adobe Premiere Pro
Benchmark @ 4K. We’re not expecting
those cases will only ever be compared
against other L9i-tested chassis.
Once temperature testing is completed
at stock, we’ll swap out the cooler for a
Corsair Hydro H100X 240mm AIO, and
install the cooler with those same two
fans for consistency. Then we’ll install up
to eight 120mm ML120 fans in what we
consider to be the best orientation.
For temperature tests for the CPU
we’ll note the ambient temperature and
massive differences here with render
time, but if the board is auto-overclocking
more than it should, and we’re getting
higher temperatures and higher synthetic
results but not seeing a decrease in
render time here, then there’s a problem.To capitalize on all that we’ve also
paired it with an extensive array of power
draw and temperature tests. We’ll be
using a 10-minute run of Prime95 Blends
test to note the max CPU temperature and
max VRM temperature, and then using
that same run to identify CPU power draw
from the wall under load. Finally, we’ll
perform one last run on 3DMark: Fire
Strike, running a looped “Combined” test
for 10 minutes, noting the max wattage
drawn from the wall to better simulate
intense gaming loads.CASE REVIEW TEST BEDSCPU Intel Core i9-9900K
