They use the same OEM. If you check GC68 you will find Akasa written somewhere on it, because they actually make them for Akasa. But you might be right, Akasa does look polished better.
Wow garyboz, you are right!
But then that would mean stevejst must be wrong.
How could that be????:Q:Q
It now looks like the Akasa 824 may simply be a cheap knockoff.
As pointed out, close inspection shows that the SVG HSF has more "meat" (therefore better cooling)
and the knockoff is not tapered as much.
This would explain why the review stevejst pointed out didn't back up the results we testers got with the unit's ourselves.
So that HSF that stevejst pointed too, and the one rated at XP2100+, actually does perform worse than SVG GC68.
And sorry stevejst, but looked high and low, and nowhere does Akasa appear on the SVG hsf.
But, you could confirm that yoursekf by simply looking at yours.
Oops, I forgot. You don't even have this unit that you know so much about!

You check openlynx web site, they are selling Akasa under their original names, GC. That is OEM.
You guys are so full of it no wonder you have no idea what thermal resistance is.
Try again:
Quoted:
--------------------------------------------------------------------------------
The thermal resistance determines the quality of a heatsink - the lower the number, the better the cooling performance. In principle, the results of the thermal resistance are closely connected to the cooling temperature. The best result was achieved by the Swiftech MC462, which reached a C/W value of 0.16. This places it considerably ahead of its sister product (the Swiftech MC370-0A) which ranked first in the previous test.
In general, if the specific cooling capability is within the range of 0.35 and 0.4, then we are dealing with a fairly usable heatsink/fan system. Measurements below 0.35 are very good, and those below 0.2 are absolutely top class.
--------------------------------------------------------------------------------
That is from Tom's hardware web site, heard of it? http://www6.tomshardware.com/cpu/01q1/010306/cooler-05.html
You should start reading that instead of web sites that test overclocking on a Duron 600. If you try to find a place for your GC68 on the graph from Tom's Hardware article, you would quickly realize why there is no reputable review of it except the one I found on Akasa 824.
Your GC68 cooler has thermal resistance above 0.6, Galaxy puts it at 0.683. Need reference?
I mentioned as well that if you want a significantly better cooler, you can get it at SVC if that is your favorite site. They have a nice TI-V77L, which is very high in the database of frostytech (another web site you should start reading to inform yourself) and has stated thermal resistance of 0.4 which means it is a nice deal for $16.
It seems miracle happens only for you. What you pay $6 is worth $6, there is no magic about it. You can find these and similar with a better fan on many places, I can count at least 4 that I know of, all for $6-8.

RobsTV, get glasses, take the fan off and look better.

To give you more to look for, Nexgen uses GC heatsink as well and puts Sanyo-Denki high speed fan on it. Then it becomes $12 more which is about the value of fan. Need reference?
Have a good day, it has been nice talking to you.

Children, children!! Looks like we might have to clip some heatsinks on a few heads here. I suggest you take any technical discussions / arguments over to the Cases and Cooling forum.
When I ordered the GC68 the box said GC118 on it. SVC don't advertise a GC118 so I guess this is what they're now calling a GC68. It has a *mirrored* finish, as I said in my first post. The heatsink it replaced on my system was a Dynatron copper one with a 60-80mm converter and a 80mm 2500rpm 80 fan. With the same spec of fan the GC is outperforming the Dynatron by 3 or 4C. Another reason I'm glad to be shot of the Dynatron is because its fins were so close together it was clogging up with dust every couple of weeks. I doubt if the GC will have as bad a problem with dust.

YOU CANNOT COMPARE THERMAL RESISTANCE FROM DIFFERENT REVIEWS! THE HEATSINKS ARE SIMILAR BUT NOT THE SAME. You CANNOT do a direct comparison of the two. Many manufacturers manufacture things for different companies. Just because one company manufactures both does not mean that they are the same. JVC and Panasonic are the same company. Are all their products the same? No. Are many similar? Yes. Same with Ford and Mazda, etc.
The stevejst is a threadcrapping post whore timeline. THIS IS JUST FROM ONE DAY IN ONE THREAD. I have not cross referenced his posts in other threads or the FW posts. I haven't crono'd them and left them post by post so you can verify if you want to. I couldn't make something like this up.

80 replies to get us this far from hot deals. Much faster than 300.
It seems to me I saw a hardware forum somewhere on the Anandtech site. Something like "General Hardware". I think they also have one on overclocking.
I'm trying to resist, by the heck with it!
Thermal resistance is simply a calculated value done from measuring temperature difference, and supposed wattage. I say "supposed" because no one measures the CPU watts; it is too difficult. One site that liked to put this figure in their reviews invariably got higher thermal resistance as the supposed watts the CPU was generating went up. But if thermal resistance is real, it should be very nearly constant for a given HS. The guy that wrote the reviews said the HS's were "saturating". More likely the watts increased differently than predicted.
People argued with the temperature measured for one notorious HS because the fan blew directly on the CPU case, which "distorted" the measurement. Was it a distortion, or reality? However real cooling does depend on the air circulation, which may be different on different HS layouts. Circulation, where air is carried away from the CPU area, seems to drastically improve with fast fans. Another way to do this is to use a slow fan on the HS, and a big slow fan elsewhere to move air away from the CPU. It won't show up as lower thermal resistance because both the CPU slug and the air close to the HS will drop in temp about the same amount, and the difference will be the same, but the actual temps will be lower. This same thing happens with powerful fans on HS's. So besides thermal resistance, there is a second relavent condition.
All this excruciatingly scientific measuring is usually done on a test bench, not in a case where air stagnation and circulation anomalies are the norm. One might think that just removing enough air fast enough would be all you need to do, but this is simply untrue. (Put a 10" fan in a room and move around. You will find the air circulation and velocity varies drastically depending on where you are.) The air around the CPU is stuborn because the circulation is dominated by the HS fan. Getting that hot air away from the CPU is tricky.

I think a lot of people get two things mixed up. THe performance of the heatsink by itself versus the performance of the heatsink with a fan. The best heatsink in a heatsink+ fan combo round up may not be the best passive heatsink. To be more precise, the performance of heatsink/fan combos with a high speed fan and a low speed fan are also different. They do not scale linearly. I have a AX-7, among THE best in heatsink/fan combo tests, yet it's about average in terms of passive cooling. Other factors that can have a dramatic effect include the orientation of the CPU socket on the MB relative to the heatsink fins. If the fins are horizontal in a tower case, then performance is worse than if the fins are vertical.
