As you can see, the HR-07 is a new type of cooler, based upon the principles of Heatpipe cooling. Heatpipes have been very popular the last couple of years when it comes to CPU and GPU cooling, but for ram cooling, this has not been done before. The coolers have a shiny silver finish, and can, besides the cooling effect, make your rig in a windowed case look that little bit more "extreme" as well. The finish of the cooler is extraordinary: I could not detect one sharp edge or unfinished metal fin on the entire cooler. Thermalright made sure the quality is up there with the very best.

Every cooler has a double heatpipe system, which leads heat away from the heat spreader plate which is in contact with the ram chips, towards the multitude of small metal plates, or fins if you like, which sit on top of the heatpipes. All of these fins are in fact small "radiators", spaced closely together. The air inside your case can move between them, and heat can be moved away by a convective airflow between the fins. Furthermore, small holes are made into the fins to allow air to circulate even better and allow for better ventilation in passive mode. In addition to the passive mode, Thermalright has built in the possibility of active cooling when you're using dual ram coolers, in dual channel operation. The fans can be directly attached to the coolers, and can provide active airflow to offer even better convective heat dissipation.

One of the drawbacks of full graphics card water blocks is that they don't always fit the cards being used like they should. There are tolerance issues depending on the height of the ram versus the height of the GPU. Swiftech offers a cure to those ills with the MCWRamcool.

It is an understatement that performance computer hardware gets a little warm. Even with the best cooling on your CPU, motherboard, and video card, there are still components which may suffer from thermal breakdown. Despite advances in design and architecture of computer cases, the hard disk drive still manages to show a weakness in passive cooling. This is why supplimental cooling solutions will prove invaluable to preserving performance and stability. The VIZO Voyager is a just what high-performance hard drives need to sustain high output and maintain stability.

We test 4 after market VGA coolers from Thermalright, Zalman, Sytrin and Arctic Cooling on a hot running Powercolor ATI X1900 GT. Which one keeps the card the coolest and how quiet can it be done? Find out in this group test.

As you guys know by now water-cooling is one of the most efficient ways of cooling down a CPU. And it's not just efficient, it's usually very quiet to the ears and it can look fantastic in a system.

With these three key factors in mind that extremely big company, Gigabyte. Gigabyte have got a good thermal products, among them air coolers and now H2O kits. They started developing a water-cooling kit over the past year. Back in March 2006 when I was at the CeBIT their kit was still in development yet it immediately caught my attention as it was just looking really cool. What we'll be testing today is a water-cooling kit called 3D Galaxy II (GH-WIU02) and additionally to that kit something called the Blue Eye, which is water block for graphics cards that you can buy optionally with this kit.

Their new CNPS9700 LED cooler is the real deal. It's got performance, even easier installation and virtually universal compatibility. With outstanding fit and finish, a big aggressive presence and the blue LED fan, it also has great looks and would be an excellent upgrade for the stock cooler. The design could result in lower case temperatures as well, providing there's an exhaust fan in the vicinity. Overclockers can have some fun with this cooler, and in silent mode, the quiet computing crowd will be very happy as well.

To help solve this problem Cooler Master has developed a VGA water cooling solution that will remedy the heat problem as well as eliminate the noise problem. Cooler Master's Aquagate VIVA VGA cooling is an all-in-one sealed unit that offers the added benefit of being able to convert over to a CPU water cooling unit if the end-user so sees fit.

The testing results also dictate that the HR-05-SLI can be added to a system to simply remove a noisy chipset cooling solution with a silent passive one while retaining all the cooling power if not providing more. I was impressed with the HR-05-SLI for both its cooling ability and the flexibility it provides to unique layout issues. Thermalright has always been a favorite of mine with a wide range of cooling products. Introducing the HR-05-SLI after the HR-05 proved to be troublesome in certain setups, shows that Thermalright are dedicated to helping every single user that has cooling needs.

Granted, the ZEROtherm CF900 isn't up to the task for maximum effort overclockers, but that's not its target. No gimmicky design elements, no LEDs, just solid, quiet everyday performance. The CF900 would be an excellent choice for any application where good cooling and quiet operation are necessary. Its compact size only adds to its appeal.

The Vantec Stingray does surprisingly well for a single 12cm radiator water cooled system. It is also what keeps the Stingray from really performing as it easily could do much better with a dual 12cm radiator. While it's a shame it doesn't currently come with one, you can bet Vantec is improving their product.

To the point, though. For $150, you could either outfit the perpetual in your system with good, silent air cooling, or the Nautilus 500, and considering that you'll be running just one fan instead of several, it just makes sense to use something like this when it comes to systems where silence is a golden key.

Is this the most extreme cooling mod we've seen? We follow the progression of a PC70 mod that not only adds a Prometia box on the bottom, but a watercooling box on top. Some Orac-style sleeving and neat lighting effects makes this a great build!

Just last week reviewed one of the first Cooljag coolers, the AMA-H, assigned to work on the AMD AM2 platform. It was aimed at totally replacing the stock OEM unit and adding just a touch more performance. Today, Cooljag has sent us another cooler that should top the AMA-H, the AMA-P. The AMA-P is a light heavyweight that is sure to pass up the H version due to it being completely made of copper. Let's see how well it does.

The Zalman ZM-RF1 is an attractive Reserator modification that is very easy to add and configure. Despite its high quality design, it did not cool the Reserator any more than its fan-less stock housing. While it may be a great mod idea or helps finish off your desk top Reserator, it doesn't seem feasible to spend the $34.99 just to see a dim blue glow from a fan that can reach noise levels of 32db or higher.

Today we have the opportunity to look at one heavy-duty heatsink from an Austrian company by the name of Noctua, the unit we are looking at is their model NH-9U. This unit will work with either an 80 - 90 or 92mm fan and has four (4) heat pipes to help keep you system in the safe zone. Come on along as we check it out and see how well it performs against other heatsink of similar design.

Unfortunately, as this is really the first (and unfortunately, maybe the last) BTX heatsink review, the Safari stands on its own. By that I mean that I don't know how it rivals the reference solution, or other marketed coolers. There is one thing I can tell you, though. The second you boot the PC, it's like somebody's slammed a NOS bottle hooked up to a Screamer. This fan gets frelling loud. Even as the fan spins down and you idle into windows, it still has a thick, powerful growl that's more than willing to turn into a whooshing whine at the first chance. In the endgame with all its Ups and downs, it came to a point where I'd rather listen to an infant cry next to my ear than hear this heatsink. Sorry folks!

The Verax Quattro 1 is a large squarish heatsink, accented by two specialized fans which produce barely a whisper of noise. Six copper heatpipes extend up from a large copper base through a cube of aluminum cooling fins, as is popular with many silent heatsink designs. A multi-socket mounting bracket makes it possible to use the Quattro 1 with just about any processor platform. The two Verax ultra-quiet CAIRdB fans are the real selling point of the Quattro 1 heatsink however, and under power both fans generate less than 31 dbA according to FrostyTech's own measurements.

One thing that I don't like with many nForce4 motherboards is that their Northbridge chipset get quite hot and most companies thus have to use fans to coole the chipset. There's nothing wrong with using a fan but too many companies put fast spinning fans that both are loud and prone to failure after a while. I had an ASUS nForce 4 motherboard where the chipset fan not only was loud but also died on me after a year.

CrazyPC sent us an interesting chipset-cooler from Swiftech, the MCX159-CU, which uses a pure copper heatsink together with a Sunon 40mm fan.

Nowadays motherboard has many functional designs, storage interfaces and multimedia support following with more waste heat of north and south chip. Regarding this "Forcetake" releases the sole patented chip cooler that has high performance. Chipforce(JTS-0006) with adjustable heatpipe not only resolves the most crash problems of installing VGA card or other components of motherboard but also has silent feature that uses 21dBA blue led fan. The Chipforce(JTS-0006) with unique "swing" heatpipe design is absolutely your annual best choice of chip cooler. Lets get a better look.

As processors get faster so do some heatsinks, and today for review I have one that is huge. Sometimes size does matter, and sometimes it doesn't, depending who you ask of course...Anyway the guys over at AeroCool sent me their new Dominator CPU cooler to check out for review. As it is getting pretty hot here now, now is a good time to test the ability of a CPU cooler to really cool a CPU when the ambient temperature is above 90F or 32.2C for the rest of the world, but you get the point, read on tot learn more about this cooler and see if it can handle the heat.
