Liked the aesthetics of DT sniper, so decided to get it, and tested next to my EK supreme HF. Used 7 dallas 1 wire probes with crystalfonz 633 interface to log all 5 ambient air intakes on 360 rad + 280 rad, and 2 in water.
Since both blocks have a defined stopping point, mounting pressure is always same, which allows much closer mount to mount temps, plus using thin PK1 I think helps as well. Was going to do 5 mounts, but was getting very repeatable, so just did 3. All with 4mm dot in middle with PK1.
3770K, 4.6ghz, 1.35 vcore bios, prime small ffts 12K for all tests. 15 mins prime 12k to fully heat water (though usually steady state is in 7-8mins). Then logged data for 10 mins, logging core temps, water temps, and 5 intake ambients (1 intake for each 120 fan on rad) all per 1 second.
EK sup HF with plate 6, delta core to water
Mnt1 50.3
Mnt2 50.3
Mnt3 50.1
DT Sniper, delta core to water
51.8
51.9
51.6
The delta air to water ranged from 2.7 to 2.9 for EK supHF
The delta air to water ranged from 2.9 to 3.0 for DT Sniper
So EK sup HF on my 3770K was 1.5C better/lower temps than DT Sniper, based on delta core to water. ? some difference in temps from depth of channels/size base diff. (note if I use Delta core to air intake avg, EK sup hf is 1.65C better/lower temps than DT Sniper, though core to water tends to be more accurate).
Much prefer aesthetics of DT sniper, and way too lazy to change back now, so it is going to be my block for awhile.
