I get a lot of questions about overclocking and watercooling here on my website. Here is an article where I clarify all the myths about overclocking and watercooling.
1- Watercooling is dangerous. No, it isn’t. Well, in some cases maybe it is. You have two different types of watercoolings. The first one is the prebuilt one, think about the thermaltake big water. The second one is the home made one. It’s obvious that the second one is the most dangerous one.
Second point is how you built your watercooling. It’s always interesting to have a scheme before you start. You can post it on the internet and see what other, maybe more experienced users, says about it.
Third point is the testing of the watercooling. It’s always safe to test your watercooling outside your case to check if there are any leaks.
2- Watercooling is expensive. No, it isn’t. And here, it also depends on the kind of watercooling. A home made, state-of-the art watercooling system, with a loop for cpu-vga-hdd-chipset-ram… will be expensive. But a watercooling system like a corsair H50, will be as cheap as a good aircooling system, with much more performance.
3- A watercooling is inconvenient and heavy. Yes, sometimes it is. If you’re planning to get that state of the art watercooling system as described above, you will need a big case, or a case where you are sure everything will fit in. Besides, the scheme will be a good help here.
All the copper elements, tubes, pump and radiator will be heavier than normal aircooling. I guess it’s the price to pay for an optimal performance.
4- It’s too difficult. No, and again NO. I have already built a dozens of watercoolings, and no one ever failed. Why? Because you have to make some time free and be fully concentrated with what you are doing. If you can build a computer by your own, you can surely built a watercooling without any troubles. Just stay focused.
5- It looks nice. YES IT DOES
1-It is dangerous. No, it isn’t. Till a certain point. As with everything, if you know what you are doing, it isn’t dagerous. Overclocking is making your cpu running faster than he is meant to work. The frequence of a cpu is defined by FSBxMultiplier, in most of case you can’t modify the multiplier, so you will need to increase the FSB. By increasing the FSB, and increasing the frequency, the CPU will need more power. At one point he won’t have enough power and will freeze or make your computer instable. From that point you need to give him more power, or increase the Vcore. At this point it’s getting dangerous, because you will increase also the temperature of your CPU.
2-It’s easy. No, it isn’t. Many motherboard/vga brands provide you a set of tools with which you can overclock automatically, without any knowledge => NO GO. You will never gain as much performance as if you do it by your own. Check my overclock category in the menu to see my logs of overclocking, it’s always about that little Mhz more.
3-It’s illegal. No, it isn’t. There is no law that forbids you to overclock your computer. But you will loose your warranty, keep that in mind.
4-It’s expensive. No, undercontrary. You can get higher speeds at a lower price. But if you want more and more performance, by increasing the Vcore, you will need to buy better cooling. At this point, it can be expensive.
5-It’s cool. YES IT IS
