REVIEW DATE: 07/29/05
COST: Under $50 USD
AUTHOR: David Kroll
SPONSOR: Gigabyte
Intro:
Gigabyte, a name
you'd come to think of as a motherboard company, has been diversifying
themselves over the past few years. Video cards, wireless networking, laptops,
even HSF's, and there are many more things that I didn't mention. We'll take a closer look
at one of their HSF's, the G-Power Pro cooler. Sporting support for pretty much
any mainstream system board out now, it sure could be a great HSF now, and it'll
probably handle your next mainboard upgrade as well later. If that sounds
remotely enticing, continue on for the review...

The packaging:
As you can see from the below 4 pictures, the packaging that
Gigabyte used to show off the G-Power Pro is quite pleasing, and contains all
the "pertinent" information that you would need to justify your purchase. As in,
everything you just saw above and more. I'll get into more of the details of
what is in the package in the next section.
My only two comments in closing are that the knob that you
can see in picture 1, did rub against the plastic packaging, and received some
minor abrasion in shipping. Not shipping to me, but shipping from the factory I
would suspect. You can see how minor it is in picture 6 below. Getting
everything out of the packaging was more like trying to open a puzzle box. Ok,
it wasn't that bad, but it was interesting to say the least. It wasn't just pull
this flap and it's open. Not a big deal in that regard at all, I just thought
I'd mention it. And I mean that to be taken in passing.

What's inside you ask?:
I guess I'll just start with everything in picture 5. The
other two are just close-ups really, so...We have clipping mechanisms for the
LGA775, the P4, K7, and K8 sockets. We also have a manual, which I'll get into
shortly, the 3.5" bay fan controller knob, the fan controller itself, (with two
sided mounting tape) a specially designed PCI slot, incase you wanted to put fan
control at the back of your PC, arguably generic type thermal paste, mounting
hardware for the various mechanisms, cables needed for hooking up your fan
controller knob, and of course the fan controlling box.
The Manual:
To be fair, and well, honest, for the most part, the manual
is almost useless. Although it's in many languages, the pictures are far too
small, and in gray scale, to be of any use. The manual is also a bit light on
words. For example, in changing out the fan controller knob from the 3.5" bay,
to the back PCI bracket, the manual says, "Disassemble the turn knob, bolt, and
fan speed controller from the 3.5" bracket and reassemble these parts onto a PCI
bracket in sequence." There are two maybe Dime sized pictures showing the knob
disassembled from the 3.5" bay, and then the other one shows it complete in the
PCI bracket. It's just not clear on how to do it. While I'm not trying to play
dumb, and perhaps being a bit harsh, the fact of the matter is most definitely,
I had to use the PDF file of the manual to get some of the crappy pictures in
color, for a better understanding of how to mount the cooler on the K7 socket. The
other clip instructions seem a bit better, but even in the .pdf, the pictures
were too small to be useful. Go see for yourself! I've put the .pdf on my site.
It's right
HERE! It's only about 550kb, so please take a look...

Everything else that needs some commenting on:
I do really like the mounting options for this HSF. It's also
nice to see the thermal paste included. Albeit it's not a premium thermal paste,
it'll get the job done. I would probably think any self respecting enthusiast
already would have their own favorite premium paste already though. Having the
fan controller separate from the knob is a mixed blessing. The good is that you
have two mounting options for the fan controlling knob. On the other hand, there
is one more thing to hide in your case. (The fan controlling module.) That would
be important if you have a window, and it
also adds two more wires into the probably already mess of wires that are inside
your case already. My test system is...Cough...
I would like to comment a bit on the fan controlling knob.
If you weren't interested in clicking picture 6 before, you should now. Gigabyte
did a helpful thing, and put the fan speed, and Decibel rating right on the
shroud of the 3.5" bay. Perhaps not an option that is going to really make you buy it,
because generally, if you use a rheobus already, you either turn your fans down
to where you can stand it, or watch your temps, and turn them to where you feel
comfortable on your case and CPU temps. If the 3.5" bay controller looks a bit
dull, it's because there is a protective layer of film on it. It's easily peeled off,
and it protects the front of the bay device...Too bad nothing like that was on the knob...
The HSF:
In picture 8, we can see the large 110mm fan. It does look
impressive, and even more impressive when in use, I can't help to wonder why
Gigabyte didn't use a more standard fan on this HSF. It becomes quite obvious,
that after your fan fails, or heaven forbid, you break it off somehow, you have
a perfectly good HSF, or really, HS. Another thing that comes to mind is that
there is NO fan guard on it. Yes, keep your wires and fingers out of it. I can
guarantee you that if you stuck your finger at the edge of the fan when running,
it'll tear a chunk out of your finger. The tips of the blades are very sharp.
Multiply that by rotation, and like I said, missing chunk of finger...
You'll also notice the open sides of the fan. Those decrease
noise, and at the same time increase the amount of air that gets pushed down
over the fins of the HSF. That's in theory. I have no proof of concept for that,
but other HSF manufacturers are using this new technology as well. Thermaltake
comes to mind immediately.
You'll undoubtedly notice the small base of the HSF. It's
copper, and nickel plated. Copper oxidizes with exposure to air, so the Nickel
coating protects that. Copper, which incidentally is my dog's name, absorbs heat
faster than aluminum, but can't get rid of it as fast as aluminum.
Aluminum absorbs heat more slowly than Copper, but can get rid of it quicker, as
I sort of just said. That is why you see a lot of hybrid Copper/Aluminum HSF's.
There are some better alternatives to both Copper and Aluminum, but the cost in
manufacturing, and reselling with exotic metals is far away from being cost
effective for anyone. Manufacturers, sellers, or end users. I suppose someday
we'll see some, but who is going to want to buy a $600 HSF? Crap, got off topic,
not really, but...Anyway, this HSF uses heat pipe technology. heat from the base
is transferred up the four pipes which you can see, into a radiator basically.
The greater surface are of the radiator is used to disperse the heat faster than
a solid core to a "normal" HSF would do. It apparently works. Heat pipes for
HSF's are all the rage as of late aren't they?
Lastly, for this section, if in picture 9, the HSF doesn't
look quite, well, even spaced, or at a right angle, it's not. I doubt this would
affect performance in anyway, I'm just a perfectionist in some aspects. I later
gave the HSF a little bend, to look correct to me. It didn't take much, and
luckily I didn't break the damn thing like I did the clip. More on that later.

A little closer look at the HSF:
In picture 11, you can see the very thin fins around the
4 wicks that bring heat up from the CPU. Quite an engineering feet, or not
really when you really think about engineering feats, but they are all perfectly
even, and spaced perfectly. In picture 12, you can see one of the LED's that
comes out of the fan base. There are of course 4 of them, and with any LED lit
fan, looks quite spectacular. More so in person, than what a camera captures
obviously.

The base:
A bright red sticker protects the HSF base in transit, and
probably you moving around while you fumble through the manual. Fortunately, for
some n00bs, the HSF industry has realized that some people leave on protective
film accidentally. This leads to disaster as you can imagine. I'm pretty sure
there is no way someone would leave the protective sticker on this one when
installing. I'd hope not anyway. While the Nickel plated base isn't as smooth as
I would have liked to have seen, it's definitely not the worst. Although it is
pretty dull in HSF standards. I'm sure you could get a
lapping kit, and go to work if you
really wanted to. I have no idea how thick the Nickel is, but perhaps getting to
the Copper base would make you feel better. I don't know...I'm just speculating.
Maybe you can get a nice shine on the Nickel though...

Clipped:
Clipping the HSF with the K7 clip is tooless. That is much
appreciated, because if you have ever been there, in other words, putting a flat head
screwdriver, probably 30+ foot pounds of pressure to try and clip your
HSF on the socket, while pointing down at your motherboard is pretty scary. Usually,
because you can never find the exact size screwdriver to get the job done right.
I've never done it myself, but at pressure, a little slip, and it's very easy to
pop off a capacitor, or break a few traces on your mobo. After that, major
miniature soldering comes into play at a last resort, because you just
killed your board.
There are two holes lets say, for the K7 clip to fit into. That
holds the K7 bracket onto the HSF base. I did have to squeeze them a bit
together with pliers for the K7 bracket to stay snug enough, that in mounting,
it wouldn't fall out, or worse, shift a little after mounting. Not cool when you
have to mod your new HSF to work right. So yeah, seriously, the K7 bracket
wouldn't stay in between the two holes. Mounting on the K7 is the only one that
you have to take the larger base of off, to mount the K7 clip if I'm not
mistaken. Since all the other sockets have larger mounts than the old socket A,
462, or K7, ya know...
Note on picture 15: Even though the below picture seems to portray the clip
not being clipped correctly, I think it was. Or, hmm, maybe it wasn't. I think
it was just the camera angle, and I did use the flash, so...Yeah, at this time
of writing, it has been many weeks since that particular picture, in a low light
situation, was taken. I try not to remember yesterday, so I definitely try not
to remember last month.

Oh Nooo. We have a problem, and even a bigger problem:
Well, With my Lian Li 6010 case, the thumb clip unfortunately
is just about an 1/8" of an inch too high to fit back into the removable mobo
tray. I used two pairs of needle nosed pliers to try and "just bend" the thumb
clip back to clear the back of the case. I was as careful as I could be, or
thought to be, as I didn't want to break the clip. I guess I did put enough
pressure on the place I didn't want to put pressure on, because I'd know I'd
break the clip. Picture 17 explains the outcome. Oops!
Fortunately, doing some look up of other people's reviews, to try and convince
another review site to send me their K7 clip that they may not use in the
future, since Gigabyte didn't have another review sample available at the time.
A huge thanks to Jason from BigBruin.com for sending his "extra" clip, via USPS,
on his dime even. So without trying to go overboard, I am very
grateful for the clip. Thanks again bro!
I was very careful not to break this one. I found
a sanding bit that fit in an electric drill, and went to work on the stainless steel
clip. After half an hour, a drink, and a couple smokes, I figured I had ground
enough off of
the clip for it to fit. I was correct. I didn't take a picture of that, but
imagine the thumb clip with less metal on it. Shouldn't be much of a stretch
now is it?

| (16) Crap. No fit! |
(17) Oops, I broke it. My
bad! |
We'll light it up next, and do
the testing. This is the best part...
