As each thermal paste requires different curing times, different bedding in times, it made testing each thermal paste quite an arduous task in terms of time; no fear, taking our time is what Play3r does best and the following method was devised for the testing, something each of the thermal pastes had to go through prior to obtaining results.
Step 1 – Applying each thermal paste by each of the manufacturers recommended methods; where no methods were given, common sense and experience comes into play.
Step 2 – Running the test system for 24hrs with a run of Prime95’s torture test for an hour to help cure the paste in; some don’t need curing, but tough, we did it anyway!
Step 3 – After 24hrs, I ran Prime95 for 30 minutes on each of the following settings saved from BIOS; 3.9GHz @ 1.1v and 4.5GHz @ 1.25v; this is to give a completely level playing field
Step 4 – Delta temperatures were taken due to any variance in ambient temperatures; British weather can be a marvellous thing and be cold and wet one day, to warm and sunny the other. Bare this in mind when reading our results. Delta temperature is core temperature minus ambient temperature which is believed to give more consistent results, some will disagree, but I prefer this method.
With the test setup noted, the entire testing methodology being laid out in an understandable and tedious way, it’s time to see who reigns king…
