ChipCoolers HTS421B-SB Athlon
CPU Fan
Review and Installation
Last Updated: 10/30/99
INSTALLATION. The HTS421B-SB
includes a 4" X 2" X 1.5" heat sink, a high speed fan, fan
shroud, attachment clips and Shin-Etsu G749
thermal grease for maximum cooling  efficiency. The
diagram to the right came from the AMD
Athlon Processor Thermal Solution document. It is a
bird's eye view of an Athlon mated with a heat sink. I added the red
to show where the heat sink comes into contact with the CPU and where the
thermal grease goes. This stuff comes in a small plastic bag and has
the viscosity of old chewing gum. The idea is to smear a very thin
layer of the grease on the mating surfaces to fill microscopic scratches. Be
careful, the heat sink fins bend very easily and the grease likes to stay
on skin and smear on everything but the intended surfaces. I applied
the grease by dabbing a little here and there on both surfaces and gently
slicking it to a thin sheen with a disposable dishcloth. Again, be
careful. The surfaces are easily scratched and you do not want to introduce
any foreign materials (lint, dirt, or dog hairs).
 The
CPU looks like a P3 Single Edge Contact Cartridge (SECC ) and retention mechanism
looks very similar (they may be identical). The heat sink is married to the
back of the CPU (side towards the front of the computer) with two metal
attachment clips. The clips straddle the heat sink and go into the
four holes shown in red to the right. Slip the clips into the
bottom holes first and then spring them firmly into the top holes. It
takes some fidgeting; so be patient. The fan shroud with the fan snaps
onto the heat sink. I fold-up the fan cable and zip-tie it to reduce
the chance that it will get into the fan.
This heat sink does not use a heat sink support
like most others and it practically rests on the AMD North Bridge chip when
installed on an MSI MS6167 motherboard. Although it is physically large,
I do not believe the unit has enough mass to be endanger of popping loose
during shipping like some of the real large Socket 7 coolers.
