NZXT HAVIK-120 Review
Performance and Testing

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 10 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. As this unit is supplied with 2 fans I have tested in both single and dual fan configuration
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. As with 4.0GHz the Heatsink was tested in both single and dual fan configuration.
As you might suspect from the high Max temp on the 4.2 test, the Havik didn't make it though the 4.4GHz test maxing out to over 90 degrees in under 5 mins.

This lady with the whp, does she take bookings?

The reason I suggest it, is because based on thermodynamics, heat transfer has a multiplicative effect based on the difference of the two items temperatures which are touching. Meaning, more heat will transfer at a faster rate between two things (air and the heatsink fins/pipes) when the difference in their temps are greater.
Meaning, when you test two heatsinks at different ambient temperatures, the Delta Temp you measure when the ambient temps are higher will actually be skewed due to the multiplicative effect.
I don't know if this makes a huge difference in air cooled heatsinks as I've never tested it, but theoretically it would.
You cant test the difference it would make easily. Use the same rig/setup voltages, settings, etc at two difference ambient temps in the room.
If the delta temperatures for the cpu are the same/similar, then it doesnt have an effect; however, if they are different, it would show that the ambient temperature has an effect on the delta temperatures you are measuring, putting rigs in a higher ambient temp room at a disadvantage

We saw what the Havik 140 could do back in December last year when Tom took it for a spin. Now with the release of the Havik 120 it's time to see what the 140s little brother can do.
