Setup & Test Results
Kingston was nice enough to send along this rockin' set of DDR3 to use for my testing and images. This is a 12 GB tri-channel kit. Unfortunately I'm not a current owner of an i7 rig, so I will be testing in dual channel mode, as we are after temps and not performance of the memory.
See what I mean about the KHX-FAN being tall? The RAM provided has no issues with clearance, but Kingston's offerings that they plan to package this cooler with are tall like most other high end RAM these days.
The height of the KHX-FAN may have its drawbacks as well. While the 92mm Noctua fan exaggerates it a bit, the KHX-FAN does block a fair amount of the CPU coolers intake. This is also a good look at the clamping tips of the sides, you can see where they line up to grab onto the actual clip ends of the slots.
Putting things into better perspective, I stepped back a bit here to give an overall image for the size of the KHX-FAN. It's a bit wider than the Corsair, but close to the OCZ, while taller than both. The length of wire is sufficient to reach even across the motherboard if needed. I had to loop it up to keep the length at bay.
Once I got everything wired up, I took the fan for a test run. Here is the KHX-FAN in action.
I didn't think the amount of light that the KHX-FAN emits was easy to see when it was on the red motherboard, so I took these last two images to try to help show this. The KHX-FAN is sitting about 9" from the back of the box in this image; even with the lighting on you can see the glow it puts on the back wall.
One last one to leave you with the positive image of this sexy blue cooler with a flood of blue LED's to illuminate your motherboard with light.
Testing was done in dual channel mode on my X38A motherboard, both with and without the use of the KHX-FAN. All rounds of testing were done with an ambient temperature of 26.5 degrees Celsius to keep things on a level playing field. Numbers for testing were generated by allowing the PC to get into Windows and allowed to idle for fifteen minutes prior to taking a reading of the temperature on my Accurite LED thermometer that I taped under the spreader next to an IC. Once my idle number was attained, I rebooted the PC to allow Memtest 86+ Version 2.01 to boot via CD for load testing.
Watching the temperatures closely for three passes of testing, I reported the highest number I saw, usually during test #6. Our testing shows that the KHX-Fan does in fact do the job it's intended for and dropped the temperatures of the DDR3 seven full degrees under load testing.
