HHC-L61 From All
Angles |
 |
The Fan:
The fan rotates
quite slowly and does not product that much noise so the heatsink really doesn't need that fan grille for
any sort of finger protection. Luckily, the wire fan grilles pose negligible amounts
of resistance and do not obstruct airflow in any fashion. The fan connects to
the motherboard and supports RPM monitoring, as do all heatsinks these days.

Top: It is important to remember that all
heatpipes have a working temperature range where they reach maximum
efficiency. If temperatures rise too high all the liquid in the pipes is
turned to vapor and the processes is stopped dead in its tracks. If the temperature is not
warm enough then the liquid does not evaporate inside the tube either. The heatpips
in the HHC-L61 move thermal energy from where the processor core sits on the
base to the outer edges of the fins in a very clever fashion. Those areas where the
heatpipes meet the fins are directly under the fastest moving flow of air from the
fan. |

Side
A: The HHC-001 and HHC-L61 fins
differ only by that diagonal mark in the copper fins. I would assume that bump is simply there to keep the copper rigid, but who knows there may also be some other advantages to it. The aluminum fan shroud is screwed into place which is another sign of quality and attention to detail, and the Coolermaster logo is also stamped on the side. The very tips of the heatpipes poke out from the opposite side. |
 |
Side B:
The two
heatpipes stick out from the side of the heatsink a fair amount, and
depending on the motherboard you are using, this could pose a problem. At
the edge of the curve, the heatpipes are extending 20mm beyond the sides
of the cooler, so have a look out of closely placed capacitors which may be getting
bent out of the way. The thumb clip Coolermaster use on this, and
every other recent heatsink we've looked at is really nice, and very easy to
get a hold on. No tools are required and that is something we really like
to see. At the same time, the clip is not so flimsy that it bends
out of shape while you are in the middle of removing the heatsink. |

Heatsink Base:
The HHC-L61
arrives in the box with a small sticker over the base to presumably protect it from scratching and other slight marks which would
obviously pose a superficial problem. The undercut for socket cam arm clearance is good,
and in general the base is very nicely finished. It is not perfectly flat,
but the amount of 'wavyness' is very low so this should not post any major problems
as long as good thermal compound is
used. |
