Titan Fenrir Siberia TTC-NC55TZ(RB) Heatsink Review
Titan Fenrir Siberia TTC-NC55TZ(RB) Heatsink Review

Abstract: Top down cooling has its advantages, though tower cooling is usually the preferred method given its compact footprint. In this review Frostytech will be testing out a heatsink from Titan that aims to satisfy both tower and top-top heatsink designs, in one.

Information on Frostytech's test methodology is available here.

The vertical 120mm fan spins at 800-2200RPM and draws power from a 4-pin PWM motherboard fan header. The fan is held on with two wire clips and rests against vibration absorbing rubber pads. With the vertical fan removed the five 8mm diameter copper heatpipes rising up through the 106mm tall aluminum fin stack are clearly visible. Each aluminum fin here measures 0.4mm thick and is spaced ~2.5mm apart. Clearance below the bottom-most aluminum fin is 46mm.

The horizontal 140mm PWM fan spins at 700-1800RPM. The fan is loosely held on with two wire clips and rests against vibration absorbing rubber pads as well. The horizontal aluminum fin stack is about 104mm long, 130mm across. Each aluminum fin here measures 0.4mm thick and is spaced ~2.5mm apart. Clearance below the bend in the copper heatpipes is ~49mm.

The five copper heatpipes are soldered to a 6mm thick copper base block and capped off with a 7mm thick aluminum section that provides support for clamping. Much of the heatsink is elevated 45-49mm above the CPU - while it's 225mm long, there's good clearance for board mounted devices.

Looking at the Titan Siberia TTC-NC55TZRB heatsink from the top we can see the 140mm fan head on. The edges of the stamped aluminum fins are jagged to break up airflow. The base of the heatsink measures 40x45mm in size. The five 8mm diameter heatpipes are spaced side-by-side.

Base Finish and Flatness

Flipping a heatsink over to inspect the business end is often a simple indicator of overall cooler quality. More practically speaking, a heatsink is in many ways only as effective as the contact it makes with the processor - the flatter and smoother the better. Base finish is one of the criteria that Frostytech measure in the course of evaluating heatsinks, and it involves two distinct aspects. Surface Finish is the first; this is calculated with the aid of Surface Roughness Comparator that has a cross section of common machine surface finishes and their numerical surface roughness equivalents in microinches. The second is Surface Flatness. This is tested with an engineers straight edge or proven flat surface, in two axis.

The copper base of the Titan Siberia TTC-NC55TZRB heatsink is machined perfectly flat in both axis and has a surface roughness of approximately 16 microinches, which is considered very good.

Sound level measurements are coming right up next.
