Phononic Hex 2.0 Review


Performance and Testing  

The test set up consisted of the following

     Intel i7 6700K Stock (4.2GHz)@ 1.2v, 4.6GHz @ 1.3v, 4.7GHz @ 1.344v, Asus Maximus VIII Ranger, 2x4GB Corsair Vengeance LPX Memory CoolerMaster V650, Corsair Force GT 60GB Coolermaster MasterCase Pro5

As was the case with our previous set up, we'll be testing our coolers at varying levels of overclock and increasing levels of voltage.  The increase in volts means an increase in heat within the CPU, and it's this heat that the coolers need to dissipate. 

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.  As with the socket 2011, in testing we noted that if even just one of the cores exceeds 82 degrees OCCT halts the test and a fail is recorded.



It makes sense to start with the stock speed, and with stock volts, as this represents a good baseline from which to measure our results.  As always, rather than leave the setting on Auto, we've actually dialed in the stock voltage we require, in this case it's 1.2 volts for a nice stable vanilla 4.2 GHz.  Although these low volt low overclocks represent a good baseline to start from, they're not where the actions at, so for that we'll need to add more volts.

To get to 4.6GHz we had to up the volts to 1.3Volts  At the higher levels of heat generated by the increase in voltage required for the 4.6GHz 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.

Upping the volts still further we achieve a stable 4.7GHz overclock at 1.35v.  This might not seem a huge increase on 4.6GHz, but the additional heat generated by that seemingly small bump in core voltage does seem to challenge the coolers that bit more, and so as before it's here we start to separate the men from the boys, as lesser coolers may not able to disperse the increased heat effectively. Again we see a jump of 10 degrees or so from the figures at 4GHz.  Only the cream of the crop will excel at this level.

As always thanks for the great investigation and presentation of data! I'd be interested in knowing what sort of power draw the different TEC modes incur. If the draw is high enough to really justify that PCIe supply, how does that affect the case temperatures?Quote

holy cow a pelt!? the 00's called, they want their watercooling back!

in all seriousness I'm gonna have a nose through this later, but hawt dayum, seeing a pelt brings back some memoriesQuote

I think that heatsink/material design has gone that far that for something like cpu cooling a peltier module would be considered obsolete...

Why waste more energy in cooling a cpu other than one/two fans spinning...

While the idea is interesting I really don't see the purpose of a peltier here. Surely as it requires a fairly high amount of electricity to be powered, it is going to be producing heat energy as well. Perhaps that might be contributing to its not-so-great performance.Quote

I'd be interested to know the power draw on this. Back in my day you 100% could NOT power a pelt off-of a normal PSU, they would totally burn them out. if it is indeed manageable, I'd imagine it's not a very decent pelt and thus seems a bit pointless?Quote
