Cooling a RAID card with a small noctua fan (lemmy.world)

Hi everyone,

I have a DL380 G8 server with a pretty hot raid controller, which crank the fans up in the server;

I would like to add a small 40x10 noctua fan on top of its heatsink but I don't know how can I power the fan in such a server.. I thought about USB to PWM connectors but it doesn't feel right...

There are 10pins connector inside the server, but buying a 10 pin to molex then molex to pwm feels weird too... maybe

Did any of you did something similar ? What are your idea to power the fan ?

Thank you!

Im not familiar with that hardware, but if you have fans already, you can use 3/4 pin Y fan splitter cable (might be wrong name, but ut shouls point you to the right item). Any 12V or 5V pin on MBO should also work, like buying 10 pin to molex and replacing molex connector with a fan. Pay attention to voltage, you can buy 5V or 12V noctua. If you connect 12V fan to 5V line it will spin slower, but never do the other way around. Noctua 40x10 fan probably drains <1W, but still be careful

Well, problem with servers mobo is that they don't have normal fan header on them sadly... I will be careful with plugging in the right voltage fan in the right place tho, thanks for the reminder!
