Useful PWM cables
Every modern gaming rig is more dependent on the GPU than the CPU. Every gaming oriented GPU that can handle most of the mainstream games produces roughly two to three times the amount of heat of an average Intel® Core™ i5 processor (which is plenty for mainstream gaming).
Be aware that the power limitation of the fan connector found on modern graphics cards is limited to 2 amperes! This means that if the 4-pin header on the graphics card delivers 2 amperes, it can handle up to four EK-Furious Vardar FF5-120 fans, ten EK-Vardar F4-120ER fans or even more F3, F2 or F1 Vardar fans. Just pay attention that not all fans on the market are so power efficient as the EK Vardar fans. There are examples where a single 120mm fan can draw 0.6A – 7.2W, which is more than three times of the EK-Vardar F4-120ER power consumption.
