Thermalright Ultra-120 eXtreme-1366 RT and TRUE Copper

Ultra-120 eXtreme cooler from Thermalright has long been one of the leaders among contemporary cooling solutions and we have tested it quite a few times already. The modification supporting LGA1366 platform comes in a clear plastic package that differs tremendously from the traditional cardboard boxes from this manufacturer:

Now the cooler model name has “1366” added to it. It indicates that the cooler is compatible with the new Intel platform for Core i7 processors. The cooler is, in fact, intended only for the LGA1366 platform, because there are no other retention kits bundled with it:

So, if you wish to us it on any other platform, you will have to purchase the necessary retention kits separately.

Let’s take a look at the cooler:


As you can see, now it comes with a fan in a plastic frame that catches on to the sides of the heatsink with special hooks. Thermalright TR-FDB-1600 fan is built using Fluid Dynamic Bearing technology with promised 60,000 hours MTBF:

The fan rotation speed is constant and equals 1600RPM. The generated airflow is 63.7CFM and the noise shouldn’t exceed 28dBA. The cooler with a fan attached to it weighs 946g.

Our cooler sample was not free from the issue typical of almost all CPU coolers from Thermalright, namely, prominent base:


Note that one of the corners of the base plate is dropped more than the other three. The thermal compound imprint on the CPU heat-spreader speaks for itself:

The cooler is installed onto LGA1366 mainboards with the help of an X-shaped plate that should be put over the base and tightened with included screws to the backplate:

Besides Thermalright Ultra-120 eXtreme-1366 RT, we also have an all-copper version of it in our lab called Thermalright TRUE Copper Ultra-120 eXtreme:


The only differences between these two models are the heatsink material and a significantly larger weight of the copper cooler (it increased from 790g to 1900g). The base is even, which we have already pointed out in the dedicated cooler review.

Both modifications of Thermalright Ultra-120 eXtreme cooler look the same when they are installed into the system case, so I will only provide the photo of the copper version here:


I would like to add that during our test session we used two plastic ties attached to the top case panel to hold the copper Thermalright Ultra-120 eXtreme. Just like Prolimatech Megahalems, both Ultra-120 eXtreme coolers proved more efficient when they were installed with the heatpipes going across the processor heat-spreader.
