Analysis & Diagnosis:
The Cooler Base:
Xigmatek is implementing the H.D.T. design into the LOKI. The 3 heatpipes come across the base and make direct contact with the CPU’s heat spreader. The nature of the H.D.T. design inherits small grooves between the heatpipes and the rest of the block.
The cooler base is encased with an aluminum block which fills the gaps between the heatpipes and ensures that the entire area of the CPU’s heat spreader is covered.
The aluminum base has no fins on the topside.
The Heatsink and Fins:
The heatsink is made up of 42 aluminum alloy fins. The surface is brushed and polished which makes the surface smooth and shiny.
The fins have a sinus wave like pattern cut into them in the front and back. The fins are also concave cut which makes them wider on the outer edges and shorter in the middle.
The Heat pipes:
The Xigmatek LOKI deploys 3 full copper heatpipes. The heatpipes are not coated, are “U” shaped and 6mm in diameter.
The heatpipes are soldered to the base. They are located in a straight line.
The Fan:
The fan used for this cooler is coming out of Xigmatek’s standard line-up of fans. It’s a 92mm HYDRO bearing fan with 4-pin PWM molex connector. The fan puts out 52 CFM while only consuming 3.6w. The fan also has 7 blades and supports variable speed. The minimum spin up voltage is 7v, and it will generate 20 – 28 dBA across a fan speed range of 1200-2800 RPM.
The Dimension and Weight:
This cooler is a light weight at a mere 330g. That is 50g less then the 380g of Intel’s stock cooler. Even adding the fan pushes this setup barely past the Intel stock cooler with a total of 426g. The Xigmatek LOKI allows for a 2nd fan to be installed. With two fans, the cooler weights in at 522g, which is still not a heavy weight by any means. The mounting assembly is solid and will have no problem keeping this cooler in it’s place.

I fitted this fan into a build for my partner. The Asus board P8Z68 V accepted it without problems, leaving enough side clearance at the nearest memory module. It keeps the CPU Intel i5 2400 LGA1155-at a steady 19/20c at idle.
I paid about £13.50 for it and it has proved to be an excellent cooler.
Highly recommended. 5/5
I would like to get another fan as supplied for it, but to date I have not been able to locate one.

Thanks for that real world feedback. =)
Forgot….you should also lubricate the fan before using it. I opened it up and it looked bone dry so far as I could tell.
I installed this puppy today. Few observations. a) The base is polished but not perfectly smooth. There are very clear and machining marks, but they are very shallow. b) The base is completely flat on all axes compared against a razor blade. c) There is a gap between the copper heat pipe and the aluminum bits of the base.
Other than that it works much better than the stock AM3 cooler. Installation is pretty painless too.
