Performance
To provide continuity the test set up is as always
Gigabyte UD3R V2
Intel i7 950 @ 4GHz 1.25v & 1.35v
Mushkin Radioactive 2000MHz
HIS 6850
Cooler Master Storm Trooper
Corsair AX750w
For the first test we set our i7-950 overclocked to 200x20 @ 1.25v for a clock speed of 4.0GHz. We allow the system to idle for 30 minutes and then run Prime95 'maximum heat maximum stress' setting for a further 30 minutes
After 30 minutes we note the temperatures of all cores and the ambient temperature of the room. An average of all cores is taken, then the ambient temperature is removed from this figure and this gives us the delta temperature. Delta is the temperature difference above ambient which is a truer reflection of the heat-sink performance rather than mere maximum figures. Testing in an Igloo or the Sahara would give vastly different maximum temperatures, yet the Delta could be the same.
The second test follows all steps from above but with a 200x21 @ 1.35v for 4.2GHz overclock, the extra voltage in this test allows us to see if the heat-sink can cope when extreme loads and overclocks are applied.
With the temps obtained at 4.0 and 4.2GHz I was hopeful of an entry into the elusive 4.4GHz club. Alas it was not to be as the cooler let a core stray over the cut off point we set for testing of 90 degrees.

the fight, but the nominal usage looks good. the fans are quite different with the 2-tone
feature. thanks again

ie: the cases used made no difference from one to another how the heatsink performed.
I'm kind of surprised to see that the K2 falls behind the "big boys" significantly, while other reviews place it straight above the NH-D14!

dude, it was just a friendly suggestion, no need to delete my posts, because you ran out of arguments.

Top of the range dual tower heatsink from German manufacturers Alpenfohn but will K2 be a mountain or a molehill?
