I’ve been using Fluid XP+ Nano-Fluid Alien Green UV liquid coolant in a custom liquid cooling system for a while now and I’m quite happy from its performance, especially being one of the most expensive and claimed to be top performing liquid coolant at the moment. This special liquid uses nano-technology to stop ions from attaching themselves to the coolant, creating a molecular barrier around the coolant. Unlike other coolants which contain harmful substances like ethylene glycol, which have salts that corrode and become conductive, Nano-Fluid is all Eco based with non-ionic corrosive inhibitors, which contain no salts and no corrosive properties and this is one of the most important advantages that made me choose that coolant…

However after a few weeks of use I’ve noticed that the liquid flow inside the water cooling system has been reduced significantly and there seems to be no any apparent problem to cause that as everything seemed to work just fine. After disassembling the water cooling block on the CPU which is the most restrictive part of the water cooling system I was surprised to see the above thing showing how the liquid coolant has actually blocked the thin channels of the water block. The most likely culprit to cause that is the green coloring being used, however I did not expect so acclaimed cooling liquid to have such a serious drawback. If I’m right and the problem is with the green “paint” then probably the best choice would be to go to the clear Fluid XP+ Nano-Fluid as there should be no coloring solution of any kind added, so be careful if you are considering to use that solution!

Asus G51J 3D is actually the first gaming laptop that is intended for stereoscopic 3D gaming using the 3D Vision active shutter glasses, although you can still play in 2D mode at 120Hz without any problems if you wish to. Asus did very well in designing a very nice and attractive looking laptop on the outside with an extensive set of features and quite powerful hardware inside. Along with the laptop you also get a nice bagpack to easily carry it everywhere with you along with all the additional accessories and these include not only the bundled 3D Vision glasses, but also a gaming mouse in the form of Razer Abyssus, so you can actually be ready for gaming on the go and in S3D too…

The general idea behind the new NVIDIA Optimus technology for notebook is that it chooses the best graphics processor for running a given application and automatically routes the workload to either an NVIDIA discrete GPU or Intel integrated graphics – delivering great performance while also providing great battery life. This happens just as a Hybrid car chooses between the gas-powered and electric car engine on-the-fly and uses the most appropriate engine, NVIDIA Optimus technology does the same thing for graphics processors. NVIDIA Optimus Technology instantly directs the workload through the most efficient processor for the job, extending battery life by up to 2 times compared to similarly configured systems equipped with discrete graphics processors (GPUs). When playing 3D games, running videos, or using GPU compute applications the high-performance NVIDIA discrete GPU is used. When using basic applications, like web surfing or email, the integrated graphics processor is used and all this leads to longer lasting battery life without sacrificing great graphics performance.

Now, what we should see are companies like Alienware, for example and others that do have big and powerful gaming laptops to go and integrate Optimus, so that the battery life on these graphic powerhouses won’t be too low. I mean less than an hour on a battery while you are using the laptop for browsing and the powerful video card or even two video cards are actually not being loaded and even needed. Why should we cope up with that when with the help of Optimus the power hungry GPUs can be completely switched off electrically while they are not needed and get lets say two-three-four times longer battery life from the same laptop. Of course when you run a game it should back again switch on the powerful GPU and you’ll be able to take advantage of the top performance although the battery life will be reduced. But then again why should we sacrifice battery life when we don’t need the powerful discrete GPU and that is the most serious issue the Optimus technology is addressing and is doing this with a simple, but very effective approach that simply works for just about everyone. You don’t have to be a power user or aware of the fact you need to switch something by hand every time, it all happens automatically, but only when you need it…
