 Testing
Here at the stock turbo frequency of 3.6Ghz none of the CPU coolers had a problem and the EX-XCL Predator 360 came in second place after the EKWB EK-KIT L360.
Turn the OC heat on and we see the EK-XLC in second spot behind its EKWB brother yet again, and both EKWB products take the top of the charts with the EK-Kit L360 slightly edging out the EK-XLC Predator 360.
Popping up to 4.3 GHz we see the EK WB products taking the top of the chart with the EK-XLC Predator 360 hitting 65°C under load.
Here at 4.4GHZ on the I7 5820K we saw many of the coolers dropped out at 90°C. While the Corsair offering held at 89°C, the EK-XLC Predator 360 held at 73°C load and 41°C idle. We cut the testing off at 4.4GHz, as our 5820K is capable of 4.6GHz but only overvolted, which we do not encourage.
I’d say cpu cooling and gpu cooling are pretty much useless if only temperatures are measured and noise levels are completely ignored. There is not even a an opiniated subjective piece written about noise levels.
In other words, the first company that attaches a product like http://pop.h-cdn.co/assets/cm/15/05/54ca65712283e_-_leaf-blowers-01-0911-xln-2622270.jpg to a copper piece of metal that can be attached to a cpu will win the bjorn3d ultimate all time favorite award.
The EKWB Predator is whisper quiet and can’t be heard over normal system fans. If noise levels were a problem we would let you know immediately. We use a sound meter with a lower gateway of 30dBA and it wouldn’t register on our sound meter.
I find it weird on the temps of the 5820k at 4.3ghz….i run mine at 4.4 with an older h100 ..and my temps never go past 71c
Different chips require different voltages and heatsink quality and positioning on the chips varies by a great degree hence the delidding practice extreme OC’s use. Our 5820k is an early model improvements might have been made. It is also tested on an open test bed chassis which is dramatically different than an in chassis test. Open test beds don’t have air flow control front to back while chassis do. Chances are the difference you are seeing is simply chassis airflow compared to an open chassis test bed.
