Pros: Easy installation, low noise, excellent cooling, quality TIM, raised heatsink will clear mobo/chipset/VRM heatsinks, looks nice, fairly lightweight
Cons: Contact surface not perfectly flat, heat pipes may block one RAM slot

The Enermax ETD-T60-TB is a top-down flow cooler, and works similar in concept to the Intel stock CPU coolers, in that it blows cool air in from the side panel/window and distributes it over the CPU, motherboard, RAM, and chipset/VRM heatsinks. However, as you can see in the schematic below in the "Clearance" section, the design is quite different from Intel's.
The "TB" in the model name ETD-T60-TB indicates that the fan is a T.B. Silence fan, which is stabilized with magnets to reduce friction. The fin design allows for greater concentrated airflow.
Enermax also sells the ETD-T60-VD, with "VD" indicative of a Vegas Duo fan, which is slightly louder and provides slightly less cooling. The Vegas Duo fan contains multiple red and blue LEDs, and has 11 different LED rotating/revolving patterns (shown towards the end of this unboxing/review: http://www.youtube.com/watch?v=LnbwT5PrWnU). If you're willing to sacrifice performance for eye candy, check out the ETD-T60-VD.
The Enermax ETD-T60-TB has a raised heatpipe and heatsink design, which allows plenty of clearance for your motherboard/chipset/VRM's heatsinks (see a schematic of the GA-Z68MA-D2H-B3 for reference).
Unfortunately, when installed in the recommended orientation, 4 heatpipes will block the RAM slot closest to your CPU (see picture below). Not only will you be short one stick of RAM, you cannot mount RAM coolers. For those of you who are able to run enough RAM in the other adjacent slots, this should be no problem. From the second RAM slot and onwards (away from the CPU), RAM with/without large heatspreaders should be OK.
When installed, this cooler will have about a half inch of clearance from your upper-most PCI-E lane.
The wire brackets that hold the 120mm fan to the heatsink extend outwards from the heatsink less than half an inch, so you do not have to worry about the brackets making contact with a device occupying your first PCI-E lane, nor do you have to worry about the brackets making contact with exhaust fans.

The guide is fairly straightforward, all components are labeled with various letters, and the figures are printed clearly. Be sure to use the included washers!
Depending on the placement of your 4-pin fan power connector, you may consider plugging in that connector BEFORE installing the heatsink and fan. I also highly recommend leaving your 4-pin ATX power cable plugged in, as it may be more difficult to reach once the HSF assembly is installed.
The retention mechanism that holds the heatsink in place is VERY sturdy and is well designed. The HSF also comes with an adapter that allows you to convert your normal flathead/Philips-head screwdriver into a nutdriver, very handy for tightening it down!
The Enermax ETD-T60-TB comes with a small tube of Dow Corning TC-5212, a very high quality thermal paste, even comparable to Arctic Silver 5 in some benchmarks.
From a cold boot to working desktop:
Enermax ETD-T60-TB idle temperature reaches 34C.
Intel stock CPU cooler idle temperature reached 44C.
After the computer has been running for several hours and has "warmed up":
Enermax ETD-T60-TB idle temperature reaches 37C.
Intel stock CPU cooler idle temperature reaches 47C.
When running Folding@Home in uniprocessor mode (25% usage distributed among all cores), the ETD-T60-TB load temperature reaches 43C.
When running Folding@Home in uniprocessor mode (25% usage distributed among all cores), the Intel stock CPU cooler load temperature reaches 59C.
**These temperature readings were taken using Speccy (from Piriform, makers of CCleaner). Ambient temperature in the room is around 80F/~27C.
**Exhaust and intake fans on the case were all at lowest RPM settings via NZXT's built-in fan controller in the NZXT Vulcan. These fans are the default white-bladed stock fans provided by NZXT.
The fan is completely silent when the computer is idle, but when you add load and temperatures begin to increase, the PWM fan will adjust and you can definitely hear the air moving through the heatsink fins. It's still quieter than the stock Intel cooler running under the same load, but the change in fan speed and subsequent increase in airflow is definitely audible.
Definitely a solid heatsink, it can even hold its own compared to other tower-style CPU coolers. If you have a small case, this is definitely a HSF worth considering. If your motherboard chipset heatsinks tend to get hot, this cooler will pass cooler air over all of your components. Just make sure you have adequate intake and exhaust fans to keep this flow going. This cooler is priced a little higher than the competition, e.g. the Cooler Master GeminII S524, but the greater CFM and lower dBa are worth it in my opinion.
4.5/5 stars from me! This review was last updated 4/16/2012
