I just bought some new components and with this upgrade got a liquid cooling system. Specifically I got this one:

MasterLiquid Lite ML240L RGB All-in-one CPU Liquid Cooler with Dual Chamber Pump by Cooler Master

My issue is that when I went to install it I found I goofed and it won't fit in the case unless I only use one of the two fans it comes with.

I was wondering if I could just use one fan or should I exchange it for one that fits/get a new case.
 
Solution
Of course you can but it will make cooling less efficient so remaining fan may have to run faster. If that cooling is more than sufficient for it's application it may not make any difference.
