Heatsink From All Angles|
YS Tech have got their 11-bladed 70mm fan on top of the
TI-V77L this time around. Many of the original Thermoengine retailers shipped the heatsink with an after market 7000RPM fan to satisfy performance cravings. Personally, I'd rather have a quiet computer. The fan is 15mm thick, and connects to the motherboard fan header by
a 3-pin connector which supports RPM monitoring.
The heatsink top is just about the
same as the heatsink bottom, but bear with us for a moment. Each side of
the TI-V77L has 15 curved fins that range in length from 4mm to 23mm. We
were impressed to see that the fins were scalloped on both side to
increase surface area and promote turbulence. Also note that screw holes
have been made in the extrusion to accept both 70mm and 60mm
configurations. The central copper core appears to be 20mm in
No matter how much we would all like to see
tooless heatsinks become standard, the TI-V77L does require a small screw driver at some point.
Much of the tensioning is taken up by the small lever on the left hand side.
Each of the 15 fins are roughly 0.9mm thick and 21mm tall. The fins are spaced widely
at 3mm distances.
The fan shroud which supports the YS Tech fan 6.5mm above the top of the heatsink also doubles as a frame for the attachment mechanism and lever. The base of the heatsink has a bevel to help keep fingers from being sliced up. The base is undercut 2mm to clear the socket cam arm.
Looking at the base of the TI-V77L
is like looking at the top of it.
Unlike traditional extruded heatsinks this one is essentially sitting on its side. The base finish
is very good, and the left hand
side undercut 2mm for socket cam arm clearance. The heatsink comes with a small patch of
gray wax-like phase change material over the copper core. We removed this material before going about our thermal tests.
