This type of test can tell you a few things about your OC such as if your cooling system is adequate enough to dissipate the maximum heat output over extended periods of time, if there is a heat-induced instability, and if you're throttling... you've pushed it too far.
Hopefully, Prime95 last versions (28.x) are not used to evaluate seriously the PC coolings...Otherwise, no one could overclock except high-end water cooling and low voltages !
The standard Prime95 version to evaluate cooling and compare rigs together on a standard and common basis is Prime95 v26.6
Everything explained here at "Section 13" of this nice thread (The guy who wrote it is an INTEL thermal specialist) :
Of course, for stability, we don't use anymore v26.6 for last CPU's releases.
Aida64, Realbench or Prime95 versions later than v26.6 (For those who are able to sustain 80°c max core temperatures during several hours..means high end water cooling and/or low Vcore).
All tests are referred at 22°C.
