Although we were a little concerned about the location of one of heatpipes in the heatsink array, the contact between the heatpipes and the heatsink plates is impeccable. We see that they are soldered together instead of being glued with thermal glue:
The heatpipes are also carefully soldered to the cooler base grooves, which is another pleasing observation:
The thinnest part of the heatsink base plate beneath the heatpipes measures 1.8mm. The base surface finish is absolutely stunning: it is just a tiny bit away from the mirror-shine:
However, Thermaltake TMG IA1 cooler we received couldn’t boast an impeccably even base. As you see from the thermal interface imprint, one of the corners of the base is bent. Nevertheless, we decided not to fix this issue, because the contact area between the cooler base and the CPU heat-spreader is still smaller than the base plate itself. In other words, that part of the base that contacts the CPU heat-spreader is even enough to ensure tight contact. Anyway, let this be the manufacturer’s concern.
The fan is attached to an aluminum stand that is screwed on to the top and bottom heatsink plates. This is what the heatsink looks like with the fan and its retention stand removed:
The heatsink plates are of petty complex shape, so it is very hard to calculate its effective surface without any graph paper at hand.
The 120-mm fan has 9 blades. It is attached to the stand with three screws. The fan uses a slide bearing with 30,000 hours or about 3.4 years MTBF.
The rotation speed of the fan may be adjusted with a small and not very handy regulator in the 1300-2100 RPM interval. The manufacturer claims that the maximum airflow is 70.3 CFM at maximum fan rotation speed. The minimum level of noise is claimed to be 20 dBA at the lowest fan rotation speed. The maximum static pressure is 2.51 mmH2O, current – 0.55A and power consumption about 6.6W. Moreover, the fan of this new cooler has blue LEDs in it.
