[H] closed loop water coolers

[Winterlight]

I am putting a media server together using parts 
I have around my office.I have everything except 
for the  Intel® Core™ i7-4930K 130TP cooler. This 
computer will never be over clocked in any way 
and will always be run at default speeds. I will 
handle my media and security camera needs.  I 
would like to use a closed loop liquid CPU cooler 
to keep things quiet. The cheapest one would be 
fine. Do they all start at around  $70 or does 
anybody  know of a good one for around $40? thanks
