Power consumption of PC case fans.

[The_Absolute]

I just bought a Coolermaster HAF 932 full tower PC case for my gaming rig. It has about Five or Six, large case fans in it. I also bought a Coolermaster V8 CPU air cooler. It say's on the box of the V8, that the cooler itself can consume a maximum of 180 watts of electricity. I find it utterly impossible that it would require that much power to spin a fan. I have a Corsair TX750, 750-watt PSU. Does this cooler really take up that much power? What about the case fans?

No. http://www.frostytech.com/articleview.cfm?articleID=2314"

It consumes 3.84 watts, it dissipates up to 180.

I can assure you that the power consumption of PC case fans and CPU coolers is an important consideration when building a gaming rig. While it may seem unlikely that a fan would consume a significant amount of power, it is important to remember that even small changes in energy usage can have a big impact over time.

In regards to your specific case, the Coolermaster V8 CPU cooler is designed to provide efficient cooling for high-performance CPUs, which can generate a significant amount of heat. The 180-watt power consumption listed on the box is likely the maximum power draw that the cooler may consume under extreme conditions. In normal use, the power consumption may be lower.

As for the case fans, the number and size of fans can also impact power consumption. Larger fans typically require more power to operate, and having multiple fans in a full tower case can add up to a significant amount of power consumption. However, this is also dependent on the specific model and design of the fans.

In terms of your Corsair TX750 PSU, it is important to note that the wattage listed is the maximum output of the power supply, not the amount of power it constantly draws. Your PSU is designed to provide enough power for your entire system, including the CPU cooler and case fans.

In conclusion, while it may seem surprising that fans and coolers can consume a significant amount of power, it is important to consider their role in maintaining the performance and longevity of your gaming rig. It is always a good idea to research and choose components that balance energy efficiency with performance to ensure the best overall experience.
