Test Method
All our coolers follow the same rigorous testing conditions. We strapped on a single 120mmx38mm fan in the shape of the San Ace 9G1212H1011, widely considered one of the best fans on the market due to its under-volting ability (lower RPM) and high static pressure – perfect for heatsinks. This fan can produce up to 99CFM at full speed. If a heatsink is supplied with a fan, we shall be testing that stock fan(s) on full RPM.
We now use LinX Build 0.6.1 for our entire load testing of heatsinks as this stresses the CPU more so than other load tests and really puts strain on the heatsinks. Idle testing was taken after a LinX run had finished. We allowed a ‘cooling off period’ of 10 minutes for the idle test. Both minimum and maximum temperatures were taken from Real Temp Build 3.58; an average of the cores was taken. Any energy saving features were disabled in the BIOS. OCZ Freeze was the TIM of choice.
All tests were run a minimum of 3 times (each run was followed by a remounting of the heatsink) and only the best results are represented. Our test system can hit 4.41GHz stable with 1.45v. However, due to the high voltage, not all heatsinks can cope, so we decided on a ‘safe’ voltage level of 1.35v, and a lower stable clock speed of 4.20GHz for our testing.
Test System
Intel Core i7 930 @ 4.20GHz w/ 1.35v
Gigabyte GA-X58A-UD7
HIS HD 5850 1024MB
Corsair Dominator GTX2
Enermax Modu87+ 700W
Intel X25-M G2 80GB
Installation
The EVO is supplied with the usual kit that has previously graced past Fenrir coolers, except this time the Socket LGA 1156 kit is included inside rather than a plastic bag stuck on outside that usually splits open.
Supported Sockets: Intel LGA775, Intel LGA1156, Intel LGA1366, AMD 754, 939, 940, AM2, AM2+, AM3.
Supplied:
- Intel and AMD mounting kit
- TIM (Royal Grease)
- 1 set of fan clips
- Fan Resistor
Concerning installation on LGA 1366, setup was a breeze. Placing the pre-fitted 1366 backplate through the back of the motherboard was simple enough. The next step was to apply some TIM (in our case OCZ Freeze) to the processor.
The next job on the list was to fit the hold down in place. The hold down plate is seated over the contact plate with small notches cut in the plate itself to keep it relatively secure.
With the hold down in place, its simply a job of placing the cooler with the loosely attached hold down over the backplates screws shoot up through the motherboard mounting holes.
With the thumb screws supplied, attached the four screw to each of the four corners to secure the cooler in place – finish off with a screwdriver for full contact and pressure. Job done. Its that simple.
For those wondering, the clearance and height issue is not really of concern too much as if you look at the photo above, you can still fit 6GB of memory fine but only just. For taller heatspreaders, you may have airflow issues with the fan intake as the taller heatspreader may impede airflow. You could lift the fan higher though.
