This fan is a great choice for cooling components that heat up to temperatures similar to that of the sun's core.

These are great fans. Plenty loud unless you get a fan controller, then they are manageable. FYI though, if you stick your finger into the fan as I did by accident, the blades will break off easily. I was tapping the lines to cooling system and wasn''t paying attention to where my thumb was. It hit the fan and two blades broke off. My thumb is fine thankfully, but now I have to get a new fan. They do push a lot of air. I put two of these in my case, and two in my cooling system replacing the stock fans. It definitely keeps the temps down below stock level for the cooling system.

Get yourself a beefy fan controller before even considering these fans. You''ll need a controller that can handle at least 30 watts for each fan!! Yes these are the best 25mm fans on the market and blow everyone out of the water on martins flow charts in terms of CFM. Noise? Like I can hear anything over these babies. (all kidding aside these are very quiet when run below half speed)
