Replacing default Liquid CPU cooler fans

Hey guys,
I have purchased a msi dragon all in one liquid cooler (very similar to the H55) and the pre installed zalman fan on the radiator is very loud and does not seem to be pushing much air. I have it so the radiator is at the top of my case and the fan is blowing into the radiator.

I have been looking at a fan to replace the zalman one and have came across the corsair sp120s silent editions and am wondering if this would be okay to put on my radiator? Would it push enough air to cool my cpu? Also would I connect the fan into the cpu fan socket, or use a case socket?

My cpu isles around 40-45 and I would say that is quite high and when gaming reaches 67degrees. Is this number high and could using aftermarket thermal paste help the temps?
 
In principle, it's OK to replace the fan. I do it often, for exactly the same reason noise. The SP series are pretty good.

I don't know if your cooler has the ability to adjust fan speed. THose that I have knowledge of (NZXT, Intel and Corsair) usually tries to run the pump at full speed and adjust fan speed along heat. SO try and follow the installation instructions that came with your cooler and make sure to pay attention to whether the fan you are replacing is 3-pin or 4-pin (Voltage or PWM speed regulation) so you can buy the same.

There isn't much about my cooler but I found this:
The pump is designed to connect to a motherboard fan header. The CPU fan header or any other motherboard fan connector may be used. The pump provides a tach signal enabling the PC to monitor the pump operation. The pump operates at a fixed speed, no PWM signal is required.
The coolant is a mixture of demineralized water and propylene glycol with the following benefits: Anti-Freeze, Anti-Corrosion, and Anti-Bacterial. Unlike automotive anti-freeze, the coolant is safe and environmentally friendly.

Does anything in there answer anything? It mentions about PMW
