Question Fan problem on CPU cooler ?

[Jakebob]

Hello,

I have a DeepCool LS720 WH CPU Cooler and one fan is having really hard time. It's barely spinning and making awful noise.

My CPU is 13700K.

My question is, can I disconnect it and go only on 2 fans for at least a few days until I replace it? Obviously, I wouldn't try to run my CPU on 100% during that time.

I want to replace the damaged fan for another DeepCool FC120. The problem is that in their specs it says that the max RPM on these fans is 1800. However, the max RPM on my stock fans in LS720 WH is 2200 RPM. So is it still OK if I change one of them if it has different max RPM?

Thank you so much for any potential suggestions.

Yeah sure you can run without it as long as your temps don't go overboard. If case cooling is adequate, dual fan on the cooler makes minimal difference.
As for fan speeds, that doesn't matter much, it's flow and pressure that count. That's what you should compare. For a dual fan on an air cooler, second one (exhaust side) should be one with higher flow and intake one with higher pressure unless both are equal. If you are stuck with only one, it would be good to stay on intake side so it blows on the fins. Until you get it replaced you can change it's speed curve to run a bit faster than usual.
Controlling rpm for different speed fans can be a bit difficult depending on how both are connected, if both to one header, the "slower one" should have it's RPM sense lead disconnected so it doesn't confuse speed control.
Those are just fine points, in practice it makes little difference
