Thermaltake Chrome Orb
The Socket-A-compatible version of the Golden Orb, the Chrome Orb has the same basic design and a sensible one-piece clip that's no big deal to attach. It's rather more annoying to remove, but that's a common problem.
The Chrome Orb fits on most Socket A motherboards, but fouls capacitors on a few, like the Abit KT7 for instance. A quick kiss from a grinder can solve that problem.
Because it's got the same basic design as the original Orb, it doesn't work any better. The one I tested scored 0.81°C/W. but at $AU34.10 delivered, it's a good-looking, capable enough cooler for midrange systems.
Thermaltake Volcano 7
It didn't take Thermaltake long to hop on the giant-socket-cooler bandwagon and come up with their own monster unit with an 80mm fan - and this is it. The Volcano 7 is a conventional fan-on-a-heatsink cooler, basically, but it's got a number of unusual features.
Fist up - it's a flashy blighter. Shiny spiral "Tt" monogrammed finger guard, similarly shiny shroud around the top of the heat sink, blue anodising. Thermaltake do not make subtle-looking products.
If aesthetics aren't your first priority, though, there's plenty else to look at here.
The Volcano 7's big fan is thermally controlled, with a sensor that sticks out of its side to sample the air temperature inside the PC. The fan's alleged to reach a maximum speed of 5000RPM when the sensor's at or above 35°C, and drop to 2900RPM at 25°C and below.
When I tested it, I found the fan's full run-power range went from less than a watt at low temperatures (easily achieved by applying some freezer spray to the sensor) to more than 5.6 watts, achieved at about 40°C. The fan runs fairly loudly, for an 80mm unit, at full speed - but that's because it's got more power than most 80mm fans, and it's still much less annoying than a 7000RPM 60mm unit. At medium speed, it's quiet enough for all but the pickiest silent-computing enthusiasts, and at low speed it's close to inaudible.
To accommodate all users, the Volcano 7's fan is powered from one three-pin plug, and has its speed sensor wire directed to another, with a pass-through PSU-plug adaptor included as well. This lets you plug the sensor wire into your motherboard for speed monitoring, but power the relatively grunty fan from a more capable source, removing the chance of blowing up motherboard circuitry that only expects to have to run weedy little fans.
The base of the Volcano 7's aluminium heat sink has a substantial copper disc inlaid into it...
...and the disc makes direct contact with the bottom of the central fins.
This cooler may be mainly aluminium, but it's big enough to be heavy - more than half a kilogram. Despite this, the Volcano 7 only has a normal single-hook screwdriver-attach clip, which is not what I'd choose for connecting such a big chunk of metal to my motherboard. The thing'll probably be fine just sitting there, but I wouldn't knock the computer case over, if I were you.
It's hard to benchmark a cooler that changes its fan speed according to the ambient temperature, but I made numbers on the Volcano 7 at medium and full power, by testing it with the sensor hanging out in the 18°C air in my workshop, and then testing it again with a little heater resistor pushing the sensor temperature well up past the maximum-power point.
At 18°C ambient, the big cooler managed an OK but not exciting 0.71°C/W. This is a plausible inside-case temperature if your computer's well ventilated and the ambient temperature in your computer room is below 15°C - or if your computer's fairly poorly ventilated, but you're using it in an unheated room in Glasgow in January. Most computers will be a fair bit warmer than that inside.
At full power, the Volcano 7 clocked 0.61°C/W. Which is very close to copper-nutty-cooler territory.
I wouldn't be surprised if this cooler, in a normal case, managed to deliver 0.65°C/W or better when you needed it, while being able to drop back to near-silent operation when the ambient temperature falls.
The Volcano 7 is a big cooler, but the heat sink's got a rather smaller footprint than the fan suggests, so it should fit on most motherboards. I'm still a bit nervous about the clip, though. But the Volcano 7 ought to cost a lot less than the really funky 80mm-fan coolers, and it's got that distinctive Thermaltake look-at-me styling. People will buy these things by the bucketload, you mark my words.
If you want full welly all the time, you can of course install the normal 80mm fan of your choice. But the Volcano 7 should do just fine in standard trim.
At $AU57.20 delivered from Aus PC Market, the Volcano 7's well priced for what you get.
