Cooler Master Seidon 120v modding (?)

[Tremorhood]

Hi guys.

Trying to get my ITX build as silent as possible without sacrificing too much on the power end.

I recently "Modded" my Seidon 120v water cooling. I replaced the original 120mm fan with a Noctura NF-P12, which is just simply awesome - its silent as in SILENT, and it moves almost the same ammount of air as the original 40db+ fan.

After this mod, I still had a sound (loud mid-high frequency hummin) comming from the pump/cooling head itself. The pump is connected to a molex 12v (using adapter). Then i tried mounting it to the 3 pin sysfan on the mobo, which resulted in even louder noise + clicking(!).

Got myself a zalman fan mate, and connected it to the sysfan, then connected the 3pin pump to the other end of the fan mate - now, when i turn the nob all the way down (around 5v) the pump shuts up! It's perfect... Or is it?! Ive been monitoring HW monitor in idle and during load with this setup, and the temps are still fine (tho a tiny bit higher than before using the fan mate).

So temps arent a problem - but will the pump itself take damage from this "under-voltage" setting? Or will it just enhance the lifespan?

Any knowledge on this subject would be greatly appriciated! 🙂

Cheers.

Quite the opposite actually, under powering the system should make it's lifespan longer, but will sacrifice the performance of the pump. This is especially true if you are pushing your CPU to it's limit (playing games or editing video, ect.), the pump would usually compensate for this by increasing it's speed, but it can't do that when you're limiting it's power, so it might actually damage the CPU by overheating it.
