EK Predator AIO Review

Performance and Testing.

The test set up consisted of the following

Intel i7 3960X [email protected] 1.1v (undervolted) 4.0GHz @ 1.25v 4.4GHz @ 1.35v 4.6GHz @ 1.45v Gigabyte X79 UD3 Corsair Vengeance LP Memory Corsair HX850 V2 Corsair Force GT 60GB Coolermaster Storm Trooper. 

As usual we'll be testing our coolers at varying levels of overclock and increasing levels of voltage.  This in turn of course means increasing levels of heat which the coolers need to dissipate.  To begin with we start with the undervolted stock speed.  Why undervolted? well if you have things set on "Auto", you may well be using more volts than are actually required to run at the chosen frequency, for example our 3960s will run quite happily at just 1.1volts, solid as a rock, 24/7, and as such we use this as our starting point.

Continuity is very important in testing, and for this reason we keep as many of the potential variables as locked down as possible.  We will be using OCCT in Linpack X64, AVX compatible with all logical cores tested and 90% free memory utilised. The test is set up to run automatically with just a few clicks to set it going.  A 10 minute idle followed by 30 minutes of testing and a 5 minute cool down is the order of the day and brings the total test time per clock speed to 45 minutes.  So as to remove subjectivity in determining whether a CPU has failed, OCCT is set to stop the test and register a fail should the max temp exceed 80 degrees.  In testing we noted that if even just one of the cores exceeds 82 degrees OCCT halts the test and a fail is recorded.

These low volt low overclocks are not where the action's at though and aren't that much of an indicator as to how well a cooler will cope once the volts have been cranked up, so let's wind things up a bit.

Turning now to the 4GHz test we up the voltage to 1.25 volts, this is what is deemed normally as stock volts. Something we are always harping on about on the forums is AUTO does not mean stock volts, and normally if you overclocking with "auto" volts the motherboard will be upping the volts much more than needed if you were to do it manually. By whichever means it happens, upping the volts (especially from our 1.1v undervolt) does have a big impact on temps, with an average increase of 10-15 degrees seen in the results.

At the higher levels of heat generated by the increase in voltage required for the 4.0GHz overclock, fan performance, although still a factor becomes less critical, replaced instead by a coolers ability to conduct the heat up the heat pipes and more crucially the total surface area of the fins enabling convection to the atmosphere.  In the case of AIOs and water cooling the surface area of the radiator and the efficiency of the contact plate begin to play more of a factor. 

We're pleased to say the EK Predator 240 seems to be doing quite well at this point in the testing.  Things could be looking good for a new king of the charts

Upping the volts still further we achieve a stable 4.4GHz overclock at 1.35 Volts. It's here we start to separate the wheat from the chaff, with lesser coolers not able to disperse the increased heat effectively. Again we see a jump of 10 degrees or so from the figures at 4GHz. Both the H100 and the well-respected D14 are creeping into the 70s here, indicating that only the cream of the crop will excel at this level.   This is where we start to separate the men from the boys.

OK, so new King of the charts might have been a bit optimistic, but the EK is still doing pretty well.

Finally our 4.6GHz test. Don't be fooled, this is an extreme test and the graph reflects this, you will only see the very best featured in this graph.  If we really want to measure outright performance, this is where we do it.

Well the Predator 240 made it into the hallowed 4.6GHz club, but didn't exactly excel and dominate in the way we thought it might.  Especially when you think how much it costs.

I'm surprised by how well this performs, super expensive though.Quote

Been waiting for this to be reviewed and it doesn't disappoint, it's right up there with the GTi and GTX impressive! Not really sold on the "AIO" monika though it is and it isn't.. Like the Kelvins, Swiftech H220 and Tritons they are kind of in a category of their own being expandable and all, although like you say in the review conclusion it's the use of proper size fittings and hoses that make the Predator stand out, to me they are prebuilt custom loops definitely worth the money though.Quote

good to know you didn't to drill holes in your motherboard and killing it to mount it, like another reviewer that did....Quote

Yeah, I wonder who that was Quote

Good review and although EK are kings when it comes to full on watercooling I think the AIO arena is best left for companies with more experience like Corsair, Fractal and NZXT.Quote
