AIO Cooler Mega Test

Performance and Testing 

The test set up consisted of the following

Intel Kaby Lake i7 7700K
4.8GHz @ 1.25v, 5.0GHz @ 1.3v
Asus Maximus VIII Ranger
2x8GB Corsair Vengeance LPX Memory 3200MHz
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.

 

4.8GHz

Having had a fiddle with the volts we achieve a nice stable 4.8GHz overclock at 1.25 Volts (stock for most boards).  This level of overclock is going to give us a pretty good idea of how well coolers will perform when under a bit of stress.  We'd expect everything to make it through, however some may come close to the automatic 80 degree cut off wire.

5.0GHz

A bump to 1.3v saw us acheive a solid 5.0GHz Overclock.  Only the very best coolers are going to perform well with this amount of heat being pumped into them, and even then, some of them will be close to the automatic cut off point.  5.0GHz might not seem like a huge increase on 4.8GHz, 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.  Only the cream of the crop will excel at this level.

Amazing amount of in depth analysis and explanation fellows, as always, thank you for not only presenting detailed and thorough information but explaining the points you make and why certain aspects/elements are more effective.

Great to see Cryorig putting up great figures. Seems like all of their offerings are at least solid, if not phenomenal, especially for the value.Quote
