Cooler Master Hyper 212 EVO CPU Cooler: j.mp Cooler Master Hyper 212 Plus j.mp Cooler Master BladeMaster 120mm PWM j.mp Cooler Master Computer Case Cooling j.mp For those of you who don't really care about looks, pickup this 4 pack of 120mm fans. Not only can you add a second fan to the cpu cooler, you can add more fans to the rest of your case. It is a really good deal!: j.mp Fan types: The common cooling fans used in computers use standardized connectors with 2 to 4 pins. The first two pins are always used to deliver power to the fan motor, while the rest can be optional, depending on fan design and type: Ground Power - +12 V Sense - a tachometer that measures the actual speed of the fan as a pulse train, frequency being proportional to speed. With each fan rotation, there are two pulses sent through this pin. Control - PWM signal Pulse-width modulation), gives the ability to adjust the rotation speed on the fly wit hout changing the input voltage delivered to the cooling fan Cooling fans equipped with either 2 or 3 pin connectors are usually designed to accept a wide range of input voltages, which directly affects the rotation speed of the blades.

Have you ever wondered why your machine has computer cooling fans inside it? From the name itself, you can already deduce that these fans are intended to cool your computer. But is there absolutely necessary for your computer to have these fans? In order to answer this question, one has to closely examine the close relationship between machine performance and the heat produced by the numerous computer components.

The biggest or smallest size computers have different components that allow it to function properly and in a timely manner. Some of these are the central processing unit (CPU), random access memory (RAM), hard drive, and many other components in form of chips spread across the main computer board.

When the computer is in operation, these components produce heat to a point that some of them have even the capacity to give your fingers a nasty burn. The high temperature of these components can damage them and in order to ensure that their temperature remains manageable, computer cooling fans are used.

There are some first generation desktop computers which do not have any cooling fans on their casings. This was because their designers have decided that computer fans just destroy the general appearance of their desktop machines. However, to the annoyance of end users operating these computers, the heat generated by their machines is so extreme that it causes some chips to be dislodged off the main board. This causes the screen to display garbled data. In some cases, the disk of users would come out of its slot partially melted due to the hot environment inside the computer case.

In fact, when cooling fans on modern computers fail, users immediately sense that drop in their computing speed. This only shows that there is a direct relationship between the performance of your machine and the heat dissipation made possible by computer fans. This is why until now, most desktop computers are equipped with fans to hel p the various components, particularly the CPU, maintain a tolerable temperature.

While it is true that there are some laptop computer models that do not have built-in cooling fan, users buy separate fan pads to help dissipate the heat on their computers. This just goes to prove that indeed, computer cooling fans, by themselves, are also important components of any computer system. So if the temperature on the surface of the case of your desktop computer is unusually high, try to see if the fans are still working. This may be a bit of a nuisance thing to do for you, but it could also be the very act that could save you from a greater trouble.

Question by Aaron: Can I hook up my computer cooling fans in a series? I am building a computer, and I bought a Raidmax case with 4 cooling fans. Is it safe to hook all of the fans together in series, then just plug one of them into the power supply to power all of the fans? That would save some of my power connectors for other things. Best answer for Can I hook up my computer cooling fans in a series?:

Answer by MosesN
Yeah, it should be fine. If your computer starts bluescreening, pull one of them off, but Raidmax cases usually come with good enough PSUs that there shouldn't be a problem

Answer by sashawhitefur
In series, the voltage is constant, the resistance adds, but the current drops. In parallel the remains constant, the resistance stays constant, and the voltage drops. So it should work, but the fans will turn slower.

Answer by Beast
yes but if you see them going slow use two on one and two on another power cable.
