More and more I get people approaching me asking about cooling their rig. Sunbeamtech never really crossed my mind when people ask me. I tend to go with Thermalright, Zalman, Noctua, or Tuniq myself. After having my hands on the Core-Contact Freezer from Sunbeamtech, I might have to start adding them to the list of viable solutions to today's cooling needs.

The FuZion v.2.0 may not be a monumental difference from its older brother, but this prettier version has a lot going for it. Outside of the convenient Pro-Mount for LGA-775 users who want to set it and forget it, it's got a lot of fluid running through its veins.

The differences in this test may seem small, but we're dealing with a battle of some of the best of the best. The TDX, as I've said time and again, is far from too old to compete. But the FuZion manages to shave degree after degree off as my beefy test system starts to stretch its legs. It's to the point where I look at the radiator and wonder if it's becoming the limiting reagent of the system...

All of this is before you even begin looking into "options" like the same pressure nozzles you can slap onto the TDX. Restriction will be cut down to...what, the second best block in watercooling? If it's the only block in your loop, you might as well -- it's just going to bring temps down further. The whole idea of the FuZion 2.0 is attractive at this rate, and its price doesn't hurt either. At only ten quid at max over competing blocks, it's hard not to love it.

Whether you like the Delryn and chrome look or it's really not your thing, there's one thing that is undeniable. The D-Tek FuZion v.2.0 may be little more than a form revision, but that's because its function still sits as king of the high-flow world. If low temps and lower restriction are your thing, you won't go wrong choosing this block.

Unlike conventional laptop computers, the C90S is an upgradeable laptop, meaning that the user is free to replace many of its core components including the processor and the graphics card. Possibly even more interesting than this is Asus' choice of platform, not quite the standard for a mobile system.

The Asus C90S is powered by Core 2 desktop processors rather than the 'Merom' mobile variety. That includes support for the 800MHz FSB Allendale models, as well as the 1066MHz FSB Conroe processors. It is possible, then, to configure the C90S with a Core 2 Extreme X6800 processor operating at 2.93GHz if you'd choose to do so, which certainly makes the C90S a very unique laptop, or should we say mobile desktop replacement.

CoolIt Systems has a solution to tame those heat generating GPU workhorses that they call the Dual Drive Bay VGA Cooler NV Reference Series. It is a closed loop, factory sealed pre-filled system that offers maintenance free operation for SLI setups. They claim easy installation and they say that it's 'the perfect solution for any extreme gamer or overclocker that wants to push their nVidia 8800GTX, 8800GTX Ultra SLI VGA setup to the limits.' Let's see if this holds up. But first, let's delve into a little more detail as to what it is.

CoolIt Systems' Dual Drive Bay VGA Cooler NV Reference Series is comprised of a dual drive bay enclosure that houses the pump, radiator, and fan. Attached to the fan with neoprene tubing are two nVidia VGA MTEC Cooler Cold Plates. MTEC is a patented technology using multiple TECs (thermal-electric coolers) or peltiers to actually refrigerate the liquid in this pre-filled system. Since liquid cooling is better than air cooling, surely then, chilled liquid must be better even still. To learn more about thermal-electric cooling and the peltier effect, take a quick peak at the wiki. They do a much better job at explaining it than I ever could as I seem to have misplaced my slide ruler somewhere.
