Thermalfly are a new heatsink manufacturer out of Taiwan,
and the company is introducing itself with a collection of fresh thermal
solutions in a nice shade of nuclear green. FrostyTech wil be testing out a
couple of Thermalfly's CPU coolers for the socket 775 and 939/AM2 platforms in
the coming weeks, so keep you're eyes peeled! In this review it's the Thermalfly
F1-IACSHA heatsink that we'll be putting through its paces on both the
thermal and acoustic front's, and on both Intel LGA775 and AMD
K8 thermal platforms.
This is the debut for FrostyTech's new Intel
LGA775 version of the Mk.II synthetic thermal temperature
test platform! Given Intel's rapidly changing trends in lower power desktop
processors, and high wattage multi-core chips, we'll be testing with two different
heat load this time around. Anyhow, we'll touch upon the details of the new
test platform a little later in the review. Right now it's time to get back on track
as we evaluate the
F1-IACSHA, a large fully copper heatsink
which combines a 63mm diameter squirrel cage fan and a unique L-shaped copper cooling
fin array. This heatsink has a couple attributes we've never seen before in a desktop cooler...
F1-IACSHA is equipped with a four-pin Pulse Width Modulation (PWM) squirrel
cage fan that goes one step further than
BIOS determined fan speed control. At the base of the F1-IACSHA heatsink is its very
own thermistor temperature sensor, taped to the top of the copper processor block with a
small aluminum sticker. The thermistor provides accurate temperature readings to the
fan, and this determines how quickly it spins at any given moment.

If you prefer manual control over you processor
heatsink, the Thermalfly F1-IACSHA supports this as well.
A simple fan speed control dial set on a PCI bracket allows the
F1-IACSHA heatsinks' fan speed, and hence noise, to be adjusted at will.
The dial can be shut
off, reverting control of the fans' speed back to the PWM system and motherboard BIOS. All this can be
done without disconnecting any wires, which is a nice adaptation other manufactures ought
to take notice of. If you intend for
the PWM circuit to control the fan entirely, the fan speed control bracket needn't
be connected at all.
Core 2 Duo and AMD Athlon64
The Thermalfly F1-IACSHA heatsink comes with it's own
custom heatsink retention frame that's compatible with both socket 754/939/940
AMD Athlon64 and socket 775 Intel Pentium / Core 2 Duo processors. Socket AM2 is not supported as of this writing. For either
application, the plastic retention frame is attached to an included rear
motherboard metal support bracket, which uses non-standard metric threads.
AMD Athlon64 K8 motherboards and socket 775 Intel
motherboards will both need to removed from the case prior to installing the big
Thermalfly F1-IACSHA heatsink into the system.
On the positive side, the heatsink is held
in place with four tool free metal clips in a similar manner as
socket 478 heatsinks used to be, so it's very easy to configure.
FrostyTech's heatsink test methodology is outlined in detail
here if you care to know what equipment is
used, and the parameters under which the tests are conducted. Now let's move
forward and take a closer look at the Thermalfly F1-IACSHA heatsink, its
acoustic characteristics, and of course it performance in the thermal
